Why is Karvezide used? What is it for?
Karvezide is a "combination of two active substances: irbesartan and hydrochlorothiazide.
Irbesartan belongs to a group of drugs known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body that binds to its receptors, located in the blood vessels, causing them to narrow. This leads to an increase in blood pressure
. Irbesartan prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax and lower blood pressure. Hydrochlorothiazide belongs to a group of medicines (so-called thiazide diuretics) which cause increased urine production and consequently lower blood pressure. The two active ingredients of Karvezide act together causing a lowering of blood pressure values that is greater than that caused by the single drugs administered individually.
Karvezide is used to treat high blood pressure when treatment with irbesartan or hydrochlorothiazide alone has not adequately controlled your blood pressure.
Contraindications When Karvezide should not be used
Do not take Karvezide
- if you are allergic to irbesartan or any of the other ingredients of this medicine
- if you are allergic to hydrochlorothiazide or to any of the medicines derived from sulphonamide
- if you are more than 3 months pregnant (it is also better to avoid Karvezide in early pregnancy - see pregnancy section)
- if you have severe liver or kidney problems
- if you have difficulty urinating
- if your doctor determines that you have a persistently high level of calcium or a low level of potassium in your blood
- if you have diabetes or impaired kidney function and you are being treated with a blood pressure lowering medicine containing aliskiren
Precautions for use What you need to know before taking Karvezide
Talk to your doctor before taking Karvezide and if you have any of the following:
- excessive vomiting or diarrhea
- if you have kidney problems or have had a kidney transplant
- if you suffer from heart problems
- if you suffer from liver problems
- if you have diabetes

§ Refractory hypokalemia, hypercalcemia
§ Severe liver failure, biliary cirrhosis and cholestasis
§ The concomitant use of Karvezide with aliskiren-containing medicines is contraindicated in patients with diabetes mellitus or renal impairment (glomerular filtration rate (GRF)
04.4 Special warnings and appropriate precautions for use
Hypotension - Hypovolaemic patients: Karvezide has rarely been associated with symptomatic hypotension in hypertensive patients without other risk factors for hypotension.This can occur in patients with hypovolaemia or with hyponatremia due to intense diuretic therapy, low sodium diet, diarrhea or vomiting. In such cases the underlying condition must be corrected before starting Karvezide therapy.
Renal artery stenosis - Renovascular hypertension: there is an increased risk of severe hypotension and renal failure in patients with bilateral renal artery stenosis, or renal artery stenosis with functioning mono-kidney, and treated with angiotensin converting enzyme inhibitors or antagonists of angiotensin-II receptors. Although this is not documented in Karvezide therapy, a similar effect is to be expected.
Renal failure and kidney transplant: periodic monitoring of potassium, creatinine and uric acid serum levels is recommended when Karvezide is used in patients with renal dysfunction. There are no clinical data regarding the administration of Karvezide to patients with recent kidney transplantation. Karvezide should not be used in patients with severe renal insufficiency (creatinine clearance azotaemia induced by thiazides. No dosage adjustments are required in patients with renal dysfunction whose creatinine clearance is ≥ 30 ml / min. However in patients with mild renal insufficiency. -moderate (creatinine clearance ≥ 30 ml / min, but
Dual blockade of the renin-angiotensin-aldosterone system (RAAS): There is evidence that concomitant use of ACE inhibitors, angiotensin II receptor blockers or aliskiren increases the risk of hypotension, hyperkalaemia and decreased renal function (including acute renal failure). Dual blockade of the RAAS through the combined use of ACE inhibitors, angiotensin II receptor blockers or aliskiren is therefore not recommended (see sections 4.5 and 5.1). If dual block therapy is considered absolutely necessary, this should only be done under the supervision of a specialist and with close and frequent monitoring of kidney function, electrolytes and blood pressure. ACE inhibitors and angiotensin II receptor antagonists should not be used concomitantly in patients with diabetic nephropathy.
Liver failure: special attention is required when thiazides are administered to patients with hepatic insufficiency or progressive liver disease, as slight alterations in the water and electrolyte balance can result in hepatic coma. There is no clinical experience with Karvezide in patients with hepatic insufficiency.
Aortic and mitral valve stenosis, obstructive hypertrophic cardiomyopathy: as with other vasodilators, special attention is required in patients suffering from aortic or mitral stenosis, or obstructive hypertrophic cardiomyopathy.
Primary aldosteronism: patients with primary aldosteronism generally do not respond to antihypertensive medicinal products which act through inhibition of the renin-angiotensin system. Therefore, the use of Karvezide is not recommended.
Metabolic and endocrine effects: the use of thiazides may interfere with glucose tolerance. In diabetic patients it may be necessary to adjust the doses of insulin or oral hypoglycemic drugs. Latent diabetes mellitus may become manifest during therapy with thiazides.
Increases in cholesterol and triglyceride levels have been associated with the use of thiazide diuretics; however, at the 12.5 mg dose present in Karvezide, no or minimal effects have been reported.
Hyperuricaemia or gout crisis may occur in some patients taking thiazides.
Electrolyte imbalance: as for all patients on diuretic therapy, periodic monitoring of serum electrolytes at appropriate intervals is recommended.
Thiazides, including hydrochlorothiazide, can induce a water-electrolyte imbalance (hypokalemia, hyponatremia and hypochloraemic alkalosis). Alarm symptoms for a water-electrolyte imbalance are: dry mouth, thirst, weakness, lethargy, drowsiness, agitation , muscle pain or cramps, muscle fatigue, hypotension, oliguria, tachycardia, and gastrointestinal disturbances such as nausea or vomiting.
Although hypokalaemia may occur in patients receiving thiazide diuretics, this may be reduced by concomitant therapy with irbesartan. The risk of hypokalaemia is greatest in patients with cirrhosis of the liver, in patients undergoing intense diuresis, in patients receiving insufficient oral intake of electrolytes and in patients receiving concomitant corticosteroid or ACTH therapy. Conversely, due to the presence of irbesartan in Karvezide, hyperkalaemia may occur, especially in the presence of renal dysfunction and / or heart failure, and diabetes mellitus. Adequate monitoring of serum potassium is recommended in patients at risk. Potassium sparing diuretics, potassium supplements or potassium-containing salt substitutes should be administered with caution concomitantly with Karvezide (see section 4.5).
There is no evidence that irbesartan reduces or prevents diuretic-induced hyponatremia. The hypochloraemia that may occur is usually mild and requires no treatment.
Thiazides can reduce urinary elimination of calcium and can cause an intermittent and mild increase in serum calcium levels in the absence of known disorders of calcium metabolism. Marked hypercalcaemia may reveal unmanifest hyperparathyroidism. Therapy with thiazides should be stopped before performing parathyroid function tests.
Thiazides have been shown to increase urinary excretion of magnesium, causing hypomagnesaemia.
Lithium: the combination of lithium and Karvezide is not recommended (see section 4.5).
Doping test: The hydrochlorothiazide contained in this medicine may give positive results in the anti-doping test.
General warnings: in patients whose vascular tone and renal function are predominantly dependent on the activity of the renin-angiotensin-aldosterone system (eg patients with severe congestive heart failure or with kidney disease, including renal artery stenosis), treatment with inhibitors Angiotensin converting enzyme or angiotensin-II receptor antagonists affecting this system has been associated with acute hypotension, azotaemia, oliguria or rarely acute renal failure (see section 4.5). As with any antihypertensive agent (see section 4.5). , an excessive drop in blood pressure in patients with ischemic heart disease or ischemic cardiovascular disease, can lead to myocardial infarction or stroke.
Hypersensitivity reactions to hydrochlorothiazide may occur in patients with or without a previous history of allergies or bronchial asthma; however, in the former, such reactions are more likely.
Onset and / or worsening of systemic lupus erythematosus has been reported with the use of thiazide diuretics.
Cases of photosensitivity reactions have been reported with the use of thiazide diuretics (see section 4.8). If a photosensitization reaction occurs during treatment, it is recommended that therapy be discontinued. If resuming treatment is deemed necessary, it is recommended that treatment be resumed. protect areas exposed to sunlight or artificial UVA rays.
Pregnancy: therapy with angiotensin II receptor antagonists (AIIRAs) should not be initiated during pregnancy. An alternative antihypertensive treatment with a proven safety profile for use in pregnancy should be used for patients planning to become pregnant. unless continued therapy with an AIIRA is considered essential. When pregnancy is diagnosed, treatment with AIIRAs should be stopped immediately, and, if appropriate, alternative therapy should be started (see sections 4.3 and 4.6).
Lactose: this medicine contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption should not take this medicine.
Acute Myopia or Secondary Acute Angle-Closed Glaucoma: Sulfonamide-based drugs or sulfonamide-derived drugs can cause an idiosyncratic reaction, resulting in transient myopia and acute angle-closure glaucoma. Although hydrochlorothiazide is a sulphonamide, only isolated cases of acute narrow-angle glaucoma have been reported so far with hydrochlorothiazide. Symptoms include acute onset of decreased visual acuity or eye pain and typically occur within hours to weeks of onset of treatment. drug administration. Untreated acute angle-closure glaucoma can lead to permanent vision loss. The main treatment is to stop the administration of the drug as soon as possible. If intraocular pressure remains uncontrolled, rapid medical or surgical treatment may need to be considered. History of allergy to sulfonamides or penicillins may be considered risk factors for the development of acute narrow-angle glaucoma (see section 4.8).
04.5 Interactions with other medicinal products and other forms of interaction
Other antihypertensives: the antihypertensive effect of Karvezide may increase with the concomitant use of other antihypertensive agents. Irbesartan and hydrochlorothiazide (at doses up to 300 mg irbesartan / 25 mg hydrochlorothiazide) have been safely administered with other antihypertensive agents, including calcium channel blockers and beta-adrenergic blockers. Prior treatment with high dose diuretics may result in hypovolaemia and, if not corrected earlier, may lead to a risk of hypotension upon initiation of irbesartan therapy with or without thiazide diuretics (see section 4.4).
Medicines containing aliskiren or ACE inhibitors: Data from clinical trials have shown that dual blockade of the renin-angiotensin-aldosterone system (RAAS) through the combined use of ACE inhibitors, angiotensin II receptor blockers or aliskiren is associated with a higher frequency of events. adverse reactions such as hypotension, hyperkalaemia and decreased renal function (including acute renal failure) compared to the use of a single agent active on the RAAS system (see sections 4.3, 4.4 and 5.1).
Lithium : A reversible increase in serum concentrations and toxicity of lithium has been found when it is administered concomitantly with angiotensin converting enzyme inhibitors. Similar effects have been reported very rarely with irbesartan so far. Furthermore, renal clearance of lithium is reduced by thiazides with an increased risk of lithium toxicity with Karvezide. Therefore, the combination of lithium and Karvezide is not recommended (see section 4.4). If there is a real need for the combination, careful monitoring of serum lithium levels is recommended.
Medicines that affect potassium levels: the potassium depletion caused by hydrochlorothiazide is attenuated by the potassium-sparing effect induced by irbesartan. However, this effect of hydrochlorothiazide on serum potassium would be potentiated by other medicinal products that induce potassium loss and hypokalaemia (other potassium-sparing, laxatives, amphotericin , carbenoxolone, penicillin G sodium). Conversely, based on experience with other medicinal products that reduce the activity of the renin-angiotensin system, concomitant use of potassium-sparing diuretics, potassium supplements, salt substitutes containing potassium or other medicinal products capable of Increased serum potassium levels (eg sodium heparin) may cause increases in serum potassium Adequate monitoring of serum potassium is recommended in patients at risk (see section 4.4).
Medicinal products affected by changes in potassium: when Karvezide is administered in combination with other potentially dangerous medicinal products in case of alterations in serum potassium (e.g. digitalis glycosides, antiarrhythmics), periodic monitoring of potassium is recommended.
Non-steroidal anti-inflammatory drugs: when angiotensin-II antagonists are administered concomitantly with non-steroidal anti-inflammatory drugs (i.e. selective COX-2 inhibitors, acetylsalicylic acid (> 3 g / day) and non-selective non-steroidal anti-inflammatory drugs), attenuation of the antihypertensive effect may occur .
As with ACE inhibitors, the simultaneous use of angiotensin-II antagonists and non-steroidal anti-inflammatory drugs may lead to an increased risk of worsening of renal function, including possible acute renal failure, and to an increase in serum potassium particularly. in patients with pre-existing modest renal function. The combination should be administered with caution, especially in the elderly. Patients should be adequately hydrated and renal function monitoring should be considered after initiation of combination therapy and periodically thereafter.
Further information on irbesartan interactions: in clinical studies, the pharmacokinetics of irbesartan were not affected by hydrochlorothiazide. Irbesartan is primarily metabolised by CYP2C9 and to a lesser extent via glucuronidation. No significant pharmacokinetic or pharmacodynamic interactions were observed following concomitant administration of irbesartan with warfarin, a medicinal product metabolised by CYP2C9. The effects of CYP2C9 inducers, such as rifampicin, on the pharmacokinetics of irbesartan have not been evaluated. The pharmacokinetics of digoxin were not altered by concomitant administration of irbesartan.
Further information on hydrochlorothiazide interactions: when given concomitantly, the following drugs may interact with thiazide diuretics:
Alcohol: potentiation of orthostatic hypotension may occur;
Antidiabetic medicines (oral antidiabetic drugs and insulin): dosage adjustment of the antidiabetic may be required (see section 4.4);
Cholestyramine and colestipol: the absorption of hydrochlorothiazide is impaired in the presence of the anion exchange resins. Karvezide should be taken at least 1 hour before or 4 hours after these medicines;
Corticosteroids, ACTH: electrolyte depletion, particularly potassium, may be increased;
Digitalis glycosides: hypokalaemia and hypomagnesaemia induced by thiazides favor the onset of digitalis cardiac arrhythmias (see section 4.4);
Non-steroidal anti-inflammatory drugs: in some patients the administration of a non-steroidal anti-inflammatory drug may reduce the diuretic, sodium uretic and antihypertensive effects of thiazide diuretics;
Pressor amines (e.g. norepinephrine): the effect of the pressor amines can be diminished, but not so much as to preclude their use;
Non-depolarising musculoskeletal muscle relaxants (e.g. tubocurarine): the effect of non-depolarising musculoskeletal relaxants can be enhanced by hydrochlorothiazide;
Anti-gout medicines: Dosage adjustment of antigout drugs may be required as hydrochlorothiazide may increase serum uric acid levels. An increase in probenecid or sulfinpyrazone dosage may be necessary. Co-administration of thiazide diuretics may increase the incidence of hypersensitivity reactions all "allopurinol;
Calcium salts: thiazide diuretics may increase serum calcium levels due to reduced excretion. If it is necessary to administer calcium supplements or calcium-sparing drugs (eg vitamin D therapy), the calcium level should be controlled and the calcium dosage adjusted accordingly;
Carbamazepine: Concomitant use of carbamazepine and hydrochlorothiazide has been associated with the risk of symptomatic hyponatremia. Electrolytes should be monitored during concomitant use. If possible, another class of diuretics should be used.
Other interactions: thiazides may increase the hyperglycemic effect of beta-blockers and diazoxide. Anticholinergic drugs (eg atropine, beperiden) may increase the bioavailability of thiazide-type diuretics through a decrease in gastrointestinal motility and gastric emptying rate. thiazides may increase the risk of side effects from amantidine. Thiazides may reduce the renal excretion of cytotoxic drugs (eg cyclophosphamide, methotrexate) and enhance their myelosuppressive effect.
04.6 Pregnancy and lactation
Pregnancy:
Angiotensin II receptor antagonists (AIIRAs):
The use of angiotensin II receptor antagonists (AIIRAs) is not recommended during the first trimester of pregnancy (see section 4.4). The use of AIIRAs is contraindicated during the second and third trimesters of pregnancy (see sections 4.3 and 4.4).
Epidemiological evidence on the risk of teratogenicity following exposure to ACE inhibitors during the first trimester of pregnancy has not been conclusive; however a small increase in risk cannot be excluded. Although no controlled epidemiological data on risk with angiotensin II receptor antagonists (AIIRAs) are available, a similar risk may also exist for this class of medicinal products. For patients planning pregnancy, alternative antihypertensive treatment should be used. with a proven safety profile for use in pregnancy unless continued therapy with an AIIRA is considered essential.When pregnancy is diagnosed, treatment with AIIRAs should be stopped immediately and, if appropriate, alternative therapy should be started.
Exposure to AIIRAs during the second and third trimesters is known to induce fetal toxicity (decreased renal function, oligohydramnios, skull ossification retardation) and neonatal toxicity (renal failure, hypotension, hyperkalaemia) in women (see section 5.3. ).
Should exposure to AIIRAs have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended.
Neonates whose mothers have taken AIIRAs should be closely monitored for hypotension (see sections 4.3 and 4.4).
Hydrochlorothiazide:
Experience with hydrochlorothiazide during pregnancy is limited, especially during the first trimester. Animal studies are insufficient. Hydrochlorothiazide crosses the placental barrier. Based on the pharmacological mechanism of action of hydrochlorothiazide, its use during the second and third trimesters may impair fetal-placental perfusion and may cause fetal and neonatal effects such as jaundice, electrolyte imbalance and thrombocytopenia.
Hydrochlorothiazide should not be used in gestational edema, gestational hypertension or preeclampsia due to the risk of decreased plasma volume and placental hypoperfusion, without beneficial effects on the course of the disease.
Hydrochlorothiazide should not be used for essential hypertension in pregnant women, except in rare exceptions when other treatments cannot be used.
Since Karvezide contains hydrochlorothiazide, it is not recommended for use during the first trimester of pregnancy. Switching to an appropriate alternative treatment should be considered before planning a pregnancy.
Feeding time:
Angiotensin II receptor antagonists (AIIRAs):
As no data are available regarding the use of Karvezide during lactation, Karvezide is not recommended and alternative treatments with a proven safety profile for use during lactation are preferred, especially when breastfeeding newborns and preterm babies.
It is unknown whether irbesartan or its metabolites are excreted in human milk.
Available pharmacodynamic / toxicological data in rats showed excretion of irbesartan or its metabolites in milk (for details see section 5.3).
Hydrochlorothiazide:
Hydrochlorothiazide is excreted in breast milk in small amounts. Thiazides in high doses can inhibit milk production causing intense diuresis. The use of Karvezide during breastfeeding is not recommended. If Karvezide is used during breastfeeding, the doses should be kept as low as possible.
Fertility:
Irbesartan had no effect on the fertility of treated rats and their offspring up to dose levels inducing the first signs of parental toxicity (see section 5.3).
04.7 Effects on ability to drive and use machines
No studies on the ability to drive and use machines have been performed. Due to its pharmacodynamic properties Karvezide is unlikely to affect these abilities. When driving vehicles or using machines, it should be noted that occasionally dizziness or fatigue may occur during the treatment of hypertension.
04.8 Undesirable effects
Irbesartan / hydrochlorothiazide combination
29.5% of the 898 hypertensive patients who received various doses of irbesartan / hydrochlorothiazide (range: 37.5 mg / 6.25 mg up to 300 mg / 25 mg), during the placebo-controlled studies, had reactions adverse. The most commonly reported adverse reactions were dizziness (5.6%), fatigue (4.9%), nausea / vomiting (1.8%) and abnormal urination (1.4%). In addition, azotemia (BUN) (2.3%), creatine kinase (1.7%) and creatinine (1.1%) elevation were commonly observed during clinical trials.
Table 1 reports adverse reactions from spontaneous and observed adverse reactions in placebo-controlled clinical trials.
The frequency of adverse reactions described below is defined using the following convention: very common (≥ 1/10); common (≥ 1/100 to
Additional information on the individual components: in addition to the adverse reactions described above for the combination, other previously reported adverse reactions with one of the components may be potential adverse reactions with Karvezide. In Tables 2 and 3 below, adverse reactions reported with the individual components of Karvezide are listed.
Dose dependent adverse events of hydrochlorothiazide (especially electrolyte disorders) may increase with gradual increase in its dosage.
Reporting of suspected adverse reactions
Reporting of suspected adverse reactions occurring after authorization of the medicine is important. It allows continuous monitoring of the benefit / risk balance of the medicine. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system.
04.9 Overdose
No specific information is available for the treatment of Karvezide overdose. The patient should be closely monitored, treatment should be symptomatic and supportive and will depend on the time since ingestion and the severity of symptoms. Suggested measures include induction of vomiting and / or gastric lavage. activated charcoal Serum electrolytes and creatinine should be checked frequently If hypotension occurs the patient should be placed supine and promptly replenished with salts and fluids.
The main manifestations of irbesartan overdose are hypotension and tachycardia; Bradycardia may also occur.
Hydrochlorothiazide overdose is associated with electrolyte depletion (hypokalaemia, hypochloraemia, hyponatremia) and dehydration following excessive diuresis. The main signs and symptoms of overdose are nausea and sleepiness. Hypokalaemia may cause muscle spasms and / or accentuate cardiac arrhythmias associated with the concomitant use of digitalis glycosides or certain anti-arrhythmic drugs.
Irbesartan is not dialysable. The amount of hydrochlorothiazide removed by hemodialysis is not known.
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: angiotensin-II antagonists, combinations
ATC code: C09DA04.
Karvezide is a combination of an angiotensin-II receptor antagonist irbesartan and a thiazide diuretic, hydrochlorothiazide. The combination of these active ingredients determines an additive antihypertensive effect, reducing blood pressure to a greater extent than the individual components.
Irbesartan is a potent and selective angiotensin-II receptor antagonist (AT1 subtype), active for oral administration. The drug is believed to block all AT1-mediated effects of angiotensin-II, regardless of the origin or route of angiotensin-II synthesis. Selective antagonism for angiotensin-II (AT1 ) causes an increase in plasma renin and angiotensin-II levels and a decrease in plasma aldosterone concentration. In patients not at risk of electrolyte imbalance (see sections 4.4 and 4.5), potassium is not substantially changed by irbesartan alone at the recommended dosages. Irbesartan does not inhibit ACE (kininase-II), an enzyme that generates angiotensin-II and degrades bradykinin to produce inactive metabolites. Irbesartan does not require metabolic activation to exert its pharmacological activity.
Hydrochlorothiazide is a thiazide diuretic. The mechanism by which thiazide diuretics exert their antihypertensive effects is not fully understood. Thiazides act on the renal tubular mechanisms of electrolyte reabsorption, directly increasing the excretion of sodium and chloride in substantially equivalent quantities. The diuretic action of hydrochlorothiazide reduces plasma volume, increases plasma renin activity, and increases aldosterone secretion, resulting in increased loss of urinary potassium and bicarbonate and decreased serum potassium. Presumably by blocking the renin-angiotensin-aldosterone system, concomitant administration of irbesartan tends to correct the potassium loss associated with these diuretics. With hydrochlorothiazide, diuresis begins within 2 hours, the peak occurs at approximately the fourth hour, and the effect lasts approximately 6-12 hours.
Within the therapeutic range, the combination of hydrochlorothiazide and irbesartan results in a dose-dependent additive reduction in blood pressure. The addition of 12.5 mg hydrochlorothiazide to irbesartan 300 mg once daily in patients inadequately controlled on irbesartan 300 mg monotherapy resulted in a further 6.1 mmHg reduction in diastolic blood pressure compared to placebo (24 hours later). administration). The combination of irbesartan 300 mg and hydrochlorothiazide 12.5 mg results in an overall reduction in systolic / diastolic blood pressure, compared to placebo, up to 13.6 / 11.5 mmHg.
Limited clinical data (7 of 22 patients) suggest that patients not controlled with the 300 mg / 12.5 mg combination may respond when treated with the 300 mg / 25 mg combination. A superior hypotensive effect on both systolic blood pressure (PAS) and diastolic blood pressure (PAD) was observed in these patients (13.3 and 8.3 mmHg, respectively).
In patients with mild to moderate hypertension once daily administration of 150 mg irbesartan and 12.5 mg hydrochlorothiazide produced a mean reduction of 12.9 / 6.9 mmHg in systolic / diastolic blood pressure compared to placebo (24 hours post dose). ). The antihypertensive peak is reached after 3-6 hours. Continuous 24-hour monitoring of blood pressure shows that the combination of 150 mg of irbesartan and 12.5 mg of hydrochlorothiazide once daily produces a similar reduction in blood pressure over 24 hours, with an average reduction in systolic / diastolic compared to placebo, over 24 hours of 15.8 / 10.0 mmHg. Measured with continuous monitoring over 24 hours, the trough / peak effect of Karvezide 150 mg / 12.5 mg was 100%. Measured by cuff during an outpatient visit, the trough / peak effect was 68% and 76% for Karvezide 150 mg / 12.5 mg and Karvezide 300 mg / 12.5 mg, respectively. These effects were observed during 24 hours. hours without excessive lowering of blood pressure to peak and are consistent with the safe and effective lowering achieved with once-daily dosing. In patients insufficiently controlled on 25 mg hydrochlorothiazide alone, the addition of irbesartan produced a further mean reduction in values. systolic / diastolic, compared to placebo, of 11.1 / 7.2 mmHg.
The antihypertensive effect of irbesartan in combination with hydrochlorothiazide occurs after the first dose and is evident within 1-2 weeks, with a maximum effect occurring within 6-8 weeks. In long-term studies, the effect of irbesartan and hydrochlorothiazide was constant for more than one year. Although not specifically studied with Karvezide, rebound hypertension was not observed with either irbesartan or hydrochlorothiazide.
The effect of the combination of irbesartan and hydrochlorothiazide on morbidity and mortality has not been studied. Epidemiological studies have shown that long-term treatment with hydrochlorothiazide reduces the risk of cardiovascular mortality and morbidity.
The effectiveness of Karvezide is not influenced by age or gender. As with other medicinal products that affect the renin-angiotensin system, black hypertensive patients respond significantly less to irbesartan alone. When irbesartan is co-administered with low-dose hydrochlorothiazide (e.g. 12.5 mg / day), the antihypertensive response in black patients approximates that in non-black patients.
The efficacy and safety of Karvezide as initial therapy for severe hypertension (defined as SeDBP ≥ 110 mmHg) was evaluated in an 8-week, multi-center, randomized, double-blind, active-controlled, parallel-arm study. A total of 697 patients were randomized in a 2: 1 ratio to receive either irbesartan / hydrochlorothiazide 150 mg / 12.5 mg or irbesartan 150 mg which was systematically titrated (before response to the minimal dose was found) and after one week of irbesartan / hydrochlorothiazide 300 mg / 25 mg or irbesartan 300 mg, respectively.
The study recruited 58% male patients. The mean age of the patients was 52.5 years, 13% were ≥ 65 years of age, and only 2% were ≥ 75 years of age. Twelve percent (12%) of patients were diabetic, 34% were dyslipidemic and the most frequent cardiovascular pathology was stable angina pectoris present in 3.5% of the subjects studied.
The primary objective of this study was to compare the percentage of patients in whom SeDBP achieved control (SeDBP
The quality and incidence of adverse effects recorded for patients treated with combination therapy was similar to the adverse event profile for patients on monotherapy. During 8 weeks of treatment, no cases of syncope were reported in either treated group. There were 0.6% and 0% cases of hypotension and 2.8% and 3.1% cases of dizziness as adverse events reported in the combination and monotherapy patient groups, respectively.
Dual blockade of the renin-angiotensin-aldosterone system (RAAS)
Two large randomized controlled trials (ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial) and VA Nephron-D (The Veterans Affairs Nephropathy in Diabetes)) have examined the use of the combination of an ACE inhibitor with an antagonist of the angiotensin II receptor. ONTARGET was a study conducted in patients with a history of cardiovascular or cerebrovascular disease, or type 2 diabetes mellitus associated with evidence of organ damage.VA NEPHRON-D was a study conducted in patients with type 2 diabetes mellitus and diabetic nephropathy.
These studies did not demonstrate any significant beneficial effect on renal and / or cardiovascular outcomes and mortality, while an increased risk of hyperkalaemia, acute renal injury and / or hypotension was observed compared to monotherapy. These results are also relevant for other ACE inhibitors and angiotensin II receptor antagonists, given their similar pharmacodynamic properties.
ACE inhibitors and angiotensin II receptor antagonists should therefore not be used simultaneously in patients with diabetic nephropathy.
ALTITUDE (Aliskiren Trial in Type 2 Diabetes Using Cardiovascular and Renal Disease Endpoints) was a study aimed at verifying the advantage of adding aliskiren to standard therapy of an ACE inhibitor or angiotensin II receptor antagonist in patients with diabetes mellitus. type 2 and chronic kidney disease, cardiovascular disease, or both. The study was terminated early due to an increased risk of adverse events. Cardiovascular death and stroke were both numerically more frequent in the aliskiren group than in the placebo group, and adverse events and serious adverse events of interest (hyperkalaemia, hypotension and renal dysfunction) were reported more frequently in the aliskiren group than in the placebo group.
05.2 "Pharmacokinetic properties
Concomitant administration of hydrochlorothiazide and irbesartan has no influence on the pharmacokinetics of either.
Irbesartan and hydrochlorothiazide are orally active as such and do not require biotransformation to be active. After oral administration of Karvezide the absolute oral bioavailability is 60-80% for irbesartan and 50-80% for hydrochlorothiazide. Food does not affect the bioavailability of Karvezide. The maximum plasma concentration is reached 1.5-2 hours after oral administration for irbesartan and 1-2.5 hours for hydrochlorothiazide.
Protein binding is approximately 96% with a negligible amount of binding to blood cells. The volume of distribution of irbesartan is 53-93 liters. The protein binding for hydrochlorothiazide is 68%, with an apparent volume of distribution of 0.83-1.14 l / kg.
Irbesartan exhibits linear and dose proportional pharmacokinetics over the dose range of 10-600 mg. A less than proportional increase in oral absorption was observed at doses above 600 mg; the mechanism by which this is determined is unknown. Total body and renal clearance are 157-176 and 3.0-3.5 ml / min, respectively. The terminal elimination half-life of irbesartan is 11-15 hours. Steady-state plasma concentrations are achieved within 3 days of initiation of once daily dosing. Reduced accumulation of irbesartan (plasma after repeated once daily dosing. In one study, slightly higher plasma concentrations were observed in hypertensive patients. However, there was no difference in the half-life or accumulation of irbesartan. dosage in patients AUC and C
Following oral or intravenous administration of 14C-labeled irbesartan, 80-85% of the detected plasma radioactivity is attributable to unchanged irbesartan. Irbesartan is metabolised by the liver via oxidation and glucuronide conjugation. The major circulating metabolite (approximately 6%) is irbesartan glucuronide. Studies in vitro indicate that irbesartan is mainly oxidized via the cytochrome P450 enzyme CYP2C9; the CYP3A4 isoenzyme has a negligible effect. Irbesartan and its metabolites are eliminated by both biliary and renal routes. After oral or intravenous administration of 14C irbesartan, approximately 20% of the radioactivity may be recovered in the urine, while the remainder is detectable in the faeces. Less than 2% of the dose taken is excreted in the urine as unchanged irbesartan. Hydrochlorothiazide is not metabolised but is eliminated rapidly by the kidney. At least 61% of the oral dose is eliminated unchanged within 24 hours. Hydrochlorothiazide crosses the placenta, but is unable to cross the blood-brain barrier, and is excreted in breast milk.
Kidney failure : in subjects with renal insufficiency or in hemodialysis patients, the pharmacokinetic parameters of irbesartan are not significantly modified. Irbesartan is not removed during the hemodialysis process. It is reported that in patients with creatinine clearance
Hepatic insufficiency : in subjects with mild to moderate cirrhosis, the pharmacokinetic parameters of irbesartan are not significantly changed. Studies in patients with severe hepatic impairment have not been conducted.
05.3 Preclinical safety data
Irbesartan / hydrochlorothiazide: the potential toxicity of the irbesartan / hydrochlorothiazide combination after oral administration was evaluated in rats and macaques in studies up to 6 months. There were no toxicological observations of relevance to human therapeutic use.
The following changes observed in rats and macaques treated with the irbesartan / hydrochlorothiazide combination at 10/10 and 90/90 mg / kg / day were also observed with either drug alone and / or were secondary to blood pressure decreases arterial (no significant toxicological interactions were observed):
§ renal changes, characterized by slight increases in uricaemia and creatininemia, and by hyperplasia / hypertrophy of the juxtaglomerular apparatus, which are a direct consequence of the interaction of irbesartan with the renin-angiotensin system;
§ slight decreases in erythrocyte parameters (erythrocytes, hemoglobin, hematocrit);
§ Gastric discoloration, ulcers and focal necrosis of the gastric mucosa were observed in a few rats in a 6-month toxicity study with irbesartan administered at a dose of 90 mg / kg / day, hydrochlorothiazide 90 mg / kg / day and irbesartan / hydrochlorothiazide 10 / 10 mg / kg / day. These lesions were not observed in macaques;
§ decreases in serum potassium due to hydrochlorothiazide and partially prevented when co-administered with irbesartan.
Most of the above effects appear to be due to the pharmacological activity of irbesartan (blockade of angiotensin-II-induced inhibition of renin release, with stimulation of renin-producing cells) and also occur with enzyme inhibitors. conversion of angiotensin. These observations appear to have no relevance to the therapeutic dosages of irbesartan / hydrochlorothiazide used in humans.
max
of irbesartan were also slightly higher in elderly patients (≥ 65 years) than in younger subjects (18- 40 years). However, the final half-life was not significantly changed. No dosage adjustments are required in the elderly population. The mean plasma half-life of hydrochlorothiazide varies between 5-15 hours.
No teratogenic effects were observed in rats treated with the combination of irbesartan and hydrochlorothiazide at doses that produce maternal toxicity. The effects of the combination ibersartan / hydrochlorothiazide on fertility have not yet been evaluated in animal studies, as they have not been reported. Evidence of effects on fertility in animals or humans with both irbesartan and hydrochlorothiazide when given alone. However, another angiotensin-II antagonist affected fertility parameters when given alone, in studies about animals. These findings have also been seen with low doses of this angiotensin-II antagonist when given together with hydrochlorothiazide.
There is no evidence of mutagenicity or clastogenicity with the irbesartan / hydrochlorothiazide combination. The carcinogenic potential of irbesartan and hydrochlorothiazide in combination has not been evaluated in animal studies.
Irbesartan: no signs of systemic or target organ toxicity are found at the dosages used in the clinic. In non-clinical safety studies, high doses of irbesartan (≥ 250 mg / kg / day in rats and ≥ 100 mg / kg / day in macaques) caused a reduction in some erythrocyte parameters (erythrocytes, hemoglobin, hematocrit). At very high doses (≥ 500 mg / kg / day), degenerative changes in the kidneys (such as interstitial nephritis, dilatation tubular, basophilic tubules, increased plasma concentrations of urea and creatinine). These effects are considered secondary to the hypotensive effect of the drug, which leads to decreased renal perfusion. Furthermore, irbesartan induced hyperplasia / hypertrophy of juxtaglomerular cells (≥ 90 mg / kg / day in rats and ≥ 10 mg / kg / day in macaques). All these changes are considered to be induced by the pharmacological action of irbesartan. . Hyperplasia / hypertrophy of kidney juxtaglomerular cells does not appear to be of relevance to therapeutic doses of irbesartan used in humans.
No mutagenicity, clastogenicity or carcinogenicity effects were detected.
Fertility and reproductive capacity were not affected in studies in male and female rats even at doses of irbesartan causing some parental toxicity (50 to 650 mg / kg / day), including mortality at the highest dose. No significant effects were observed on the number of corpora lutea, implants, or live fetuses. Irbesartan did not affect the survival, development, or reproduction of the offspring. Animal studies indicate that radiolabelled irbesartan is detected in fetuses of rats and rabbits.
Irbesartan is excreted in the milk of lactating rats.
Animal studies with irbesartan show transient toxic effects (dilatation of the renal pelvis, hydroureter and subcutaneous edema) in rat fetuses, which regress after birth. Abortion or early embryo resorption was reported in rabbits at dosages capable of causing maternal toxicity, including death. No teratogenic effects were observed in either the rat or the rabbit.
Hydrochlorothiazide: although uncertain evidence of genotoxicity and carcinogenicity has been observed in some experimental models, the extensive experience of use in humans with hydrochlorothiazide has not shown a correlation between its use and an increase in neoplasms.
