Why is Prelectal used? What is it for?
WHAT IS PRELECTAL 2.5 mg / 0.625 mg?
PRELECTAL 2.5 mg / 0.625 mg is a combination of two active substances, perindopril and indapamide. It is an antihypertensive and is used in the treatment of high blood pressure (hypertension).
What is PRELECTAL 2.5 mg / 0.625 mg used for?
Perindopril belongs to a class of drugs called ACE inhibitors. These drugs work by dilating blood vessels, which makes it easier for the heart to pump blood through them. Indapamide is a diuretic. Diuretics increase the amount of urine produced by the kidneys. Indapamide, however, differs from other diuretics in that it causes only a slight increase in the amount of urine produced. Each active ingredient lowers blood pressure and together they work to control blood pressure.
Contraindications When Prelectal should not be used
Do not take PRELECTAL 2.5 mg / 0.625 mg
- if you are allergic (hypersensitive) to perindopril or any other ACE inhibitor, or to indapamide or any other sulphonamides, or to any of the other ingredients of PRELECTAL 2.5 mg / 0.625 mg,
- if you have had symptoms such as shortness of breath, swelling of the face or tongue, intense itching or severe skin rashes related to previous ACE inhibitor treatment or if you or a member of your family have experienced these symptoms in any other circumstances (disorder called angioedema),
- if you have diabetes or impaired kidney function and you are being treated with a blood pressure lowering medicine containing aliskiren

04.4 Special warnings and appropriate precautions for use
Special warnings
Common to perindopril and indapamide
No significant reduction in undesirable effects was observed with the low dose PRELECTAL 2.5 mg / 0.625 mg combination compared to administration of the individual components at the lowest approved doses, with the exception of hypokalaemia (see section 4.8). frequency of idiosyncratic reactions cannot be excluded if the patient is treated at the same time with two antihypertensive drugs new to him.In order to minimize this risk, the patient should be closely monitored.
Lithium
The combination of lithium with the perindopril-indapamide combination is generally not recommended (see section 4.5).
Related to perindopril
Neutropenia / agranulocytosis
Cases of neutropenia / agranulocytosis, thrombocytopenia and anemia have been reported in patients treated with ACE inhibitors. In patients with normal renal function and in the absence of other complicating factors, neutropenia rarely occurs. Perindopril should be administered with extreme caution to patients with collagen disease, on therapy with immunosuppressive agents, treated with allopurinol or procainamide, or who have a combination of these complicating factors, especially in the presence of pre-existing renal impairment. Some of these patients developed severe infections, which in a few cases did not respond to intensive antibiotic therapy. If these patients are treated with perindopril, it is recommended that white blood cell counts be performed periodically and that these patients are advised to report any signs of infection (e.g. sore throat, fever).
Hypersensitivity / angioedema
Angioedema of the face, extremities, lips, tongue, glottis and / or larynx has been reported rarely in patients treated with angiotensin converting enzyme inhibitors, including perindopril. This can occur at any time during therapy. In such cases, perindopril treatment should be discontinued immediately and appropriate monitoring initiated to ensure complete resolution of symptoms prior to patient discharge. In the case of edema limited to the face and lips, the reaction generally resolved without treatment, although antihistamines were helpful in relieving symptoms.
Angioedema associated with laryngeal edema can be fatal. In the event that there is involvement of the tongue, glottis or larynx that can cause airway obstruction, appropriate therapy should be given promptly, which may include a 1: 1000 (0, 0.1) subcutaneous epinephrine solution. 3 ml to 0.5 ml) and / or measures for maintaining a patent airway.
A higher incidence of angioedema has been reported in black patients treated with ACE inhibitors than in patients of other races.
Patients with a history of angioedema unrelated to ACE inhibitor treatment may be at increased risk of angioedema when treated with an ACE inhibitor (see section 4.3).
Intestinal angioedema has been reported rarely in patients treated with ACE inhibitors. These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no previous facial angioedema and C-1 esterase levels were normal. Angioedema was diagnosed by procedures such as CT scan of the abdomen, ultrasound or during surgery and symptoms were resolved after discontinuation of the ACE inhibitor.
Intestinal angioedema should be included in the differential diagnosis of patients treated with ACE inhibitors who present with abdominal pain.
Anaphylactoid reactions during desensitization treatment
Isolated cases of severe and life-threatening anaphylactoid reactions have been reported in patients treated with ACE inhibitors undergoing desensitizing treatment for hymenoptera stings (bees, wasps). ACE inhibitors should be used with caution in desensitized allergic patients and avoided in those undergoing immunotherapy. However, such reactions can be prevented by temporarily withholding the ACE inhibitor at least 24 hours before starting desensitization treatment, in those patients who require both ACE inhibitor treatment and desensitization treatment.
Anaphylactoid reactions during LDL apheresis
Rarely, cases of life-threatening anaphylactoid reactions have been reported in patients treated with ACE inhibitors undergoing low density lipoprotein (LDL) apheresis with dextran sulfate. These reactions were avoided by temporarily withholding ACE inhibitor treatment prior to each apheresis.
Patients on hemodialysis
Anaphylactoid reactions have been reported in patients on dialysis with high flux membranes (eg AN 69) and concomitant therapy with ACE inhibitors. The use of a different type of dialysis membrane or a different class of antihypertensive agents should be considered for these patients.
Potassium-sparing diuretics, potassium salts
The combination of perindopril with potassium-sparing diuretics, potassium salts is generally not recommended (see section 4.5).
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.
Pregnancy
ACE inhibitor therapy should not be initiated during pregnancy. For patients planning to become pregnant, alternative antihypertensive treatments with a proven safety profile for use in pregnancy should be used, unless continued therapy with an ACE inhibitor is considered essential. When pregnancy is diagnosed, treatment with ACE inhibitors should be stopped immediately and, if appropriate, alternative therapy should be started (see sections 4.3 and 4.6).
Related to indapamide
In case of liver disease, thiazide and related diuretics can cause hepatic encephalopathy. In these cases, the administration of the diuretic must be stopped immediately.
Photosensitivity
Cases of photosensitivity reactions have been reported with thiazides and related diuretics (see section 4.8). If the photosensitivity reaction appears during the treatment, it is recommended to stop it. In case the re-administration of the diuretic is necessary, it is recommended to protect the areas exposed to the sun or to artificial UVA rays.
Appropriate precautions for use
Common to perindopril and indapamide
Kidney failure
In case of severe renal insufficiency (creatinine clearance
In some hypertensive patients with no pre-existing apparent renal injury and for whom kidney blood tests have shown functional renal insufficiency, treatment should be stopped and possibly resumed at a reduced dose or with only one of the components.
Current practice must provide for these patients a periodic control of potassium and creatinine, after two weeks of treatment and subsequently every two months in a period of therapeutic stability. Renal failure has been reported mainly in patients with severe heart failure or underlying renal failure, including renal artery stenosis. The drug is generally not recommended for bilateral renal artery stenosis or impaired function in one kidney.
Hypotension and hydroelectrolytic depletion
There is a risk of sudden hypotension in the presence of pre-existing sodium depletion (particularly in patients with renal artery stenosis). Therefore, clinical signs of fluid and electrolyte depletion, which may occur during an intercurrent episode of diarrhea or vomiting, should be systematically monitored and regular monitoring of the plasma electrolytes of these patients should be performed.
Marked hypotension may require an intravenous infusion of isotonic saline.
Transient hypotension is not a contraindication to continuing treatment. Once a satisfactory blood volume and blood pressure have been restored, treatment can be resumed at a reduced dose or with only one of the components.
Potassium levels
The combination of perindopril and indapamide does not exclude the occurrence of hypokalaemia, especially in diabetic patients or patients with renal insufficiency. As with any other antihypertensive in combination with a diuretic, regular monitoring of plasma potassium should be performed.
Excipients:
PRELECTAL 2.5 mg / 0.625 mg should not be used in patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
Related to perindopril
Cough
A dry cough has been reported following administration of angiotensin converting enzyme inhibitors, the characteristics of which are persistence and disappearance after discontinuation of treatment. In the presence of this symptom, a possible iatrogenic etiology must be considered. In the event that prescription of an angiotensin converting enzyme inhibitor is nevertheless preferred, continued treatment may be considered.
Pediatric population
The efficacy and tolerability of perindopril, alone or in combination, have not been established in children and adolescents.
Risk of arterial hypotension and / or renal failure (in case of heart failure, hydroelectrolytic depletion, etc ...)
Significant stimulation of the renin-angiotensin-aldosterone system has been observed in particular during marked water and electrolyte depletions (strict low sodium regimen or prolonged diuretic treatment), in patients with initially low blood pressure, in case of renal arterial stenosis, congestive heart failure or cirrhosis with edema and ascites.
The blocking of this system by an angiotensin converting enzyme inhibitor can then cause, especially at the first intake and during the first two weeks of treatment, a sharp drop in blood pressure and / or an increase in plasma creatinine, a sign of a "functional renal failure. Occasionally this may be acute in onset although rarely and after a variable time interval.
In these cases, treatment should be started at a lower dose and progressively increased.
Elderly patients
Renal function and potassium levels should be checked prior to the start of treatment. The initial dose should be further adjusted according to the blood pressure response, particularly in the case of water and electrolyte depletion, to avoid sudden hypotension.
Patients with known atherosclerosis
The risk of hypotension is present in all patients, but particular caution should be exercised with those patients suffering from ischemic heart disease or cerebral circulatory insufficiency, starting treatment at a reduced dosage.
Renovascular hypertension
The treatment of renovascular arterial hypertension is revascularization.
However, angiotensin converting enzyme inhibitors may be useful for patients with renovascular hypertension awaiting corrective surgery or when it is not possible.
If PRELECTAL 2.5 mg / 0.625 mg is prescribed to patients with known or suspected renal artery stenosis, treatment should then be initiated in a hospital setting, at a low dose and under close monitoring of renal function and potassium levels, as some patients developed functional renal failure, which was reversible on discontinuation of treatment.
Other patients at risk
In patients with severe heart failure (stage IV) or in patients with insulin-dependent diabetes mellitus (spontaneous tendency to hyperkalaemia), treatment should be initiated under close medical supervision and at a reduced initial dose. Any treatment with b-blockers in the hypertensive patient with coronary insufficiency: the ACE inhibitor must be combined with the b-blocker.
Diabetic patients
In diabetic patients previously treated with oral antidiabetic agents or insulin, blood glucose levels should be carefully monitored during the first month of therapy with an ACE inhibitor.
Ethnic differences
Like other angiotensin converting enzyme inhibitors, perindopril may be less effective in lowering blood pressure in black patients than in non-black patients, possibly due to a higher prevalence of low renin concentrations in the population. hypertensive black race.
Surgery / anesthesia
In the case of anesthesia, and even more so if the anesthesia is performed with agents with hypotensive potential, inhibitors of the angiotensin converting enzyme can cause hypotension.
Discontinuation of treatment, if possible, is therefore recommended one day before surgery for long-acting angiotensin-converting enzyme inhibitors, such as perindopril.
Aortic or mitral valve stenosis / hypertrophic cardiomyopathy
ACE inhibitors should be used with caution in patients with left ventricular outflow tract obstruction.
Hepatic insufficiency
In rare cases, ACE inhibitors have been associated with a syndrome that begins with cholestatic jaundice and progresses to fulminant hepatic necrosis and (sometimes) death. The mechanism of this syndrome is not known. Patients on ACE inhibitors who develop jaundice or marked elevation of liver enzymes should stop taking the ACE inhibitor and receive appropriate medical attention (see section 4.8).
Hyperkalemia
Increased serum potassium concentrations have been observed in some patients treated with ACE inhibitors, including perindopril. Risk factors for the onset of hyperkalaemia include renal failure, worsening of renal function, age (> 70 years), diabetes mellitus, concomitant events, particularly dehydration, acute heart failure, metabolic acidosis, and concomitant use of potassium-sparing diuretics. (e.g., spironolactone, eplerenone, triamterene, or amiloride), potassium supplements or potassium-containing salt substitutes; patients taking other drugs associated with an increase in serum potassium (e.g. heparin) are also at higher risk.
The use of potassium supplements, potassium-sparing diuretics, or potassium-containing salt substitutes, particularly in patients with impaired renal function, can lead to a significant increase in serum potassium. Hyperkalaemia can cause serious and sometimes fatal arrhythmias. If concomitant use of the above mentioned agents is deemed appropriate, they should be used with caution and frequent monitoring of serum potassium should be performed (see section 4.5).
Related to indapamide
Hydroelectrolytic balance
Sodium levels
They must be checked before starting treatment and afterwards. A diuretic treatment can in fact cause a reduction in sodium levels, with sometimes serious consequences. The drop in sodium levels may initially be asymptomatic and regular monitoring is therefore essential. Monitoring should be performed even more frequently in elderly and cirrhotic patients (see sections 4.8 and 4.9).
Potassium levels
Potassium depletion with hypokalaemia represents the major risk of thiazide and related diuretics. The risk of developing low potassium levels (
In these cases, in fact, hypokalaemia enhances the cardiac toxicity of digitalis and the risk of heart rhythm disturbances.
Individuals with a long QT interval, of both congenital and iatrogenic origin, are also at risk. Hypokalaemia, as well as bradycardia, acts as a predisposing factor for the onset of severe heart rhythm disturbances, especially torsades de pointes, which can be fatal.
In all these cases, more frequent monitoring of potassium levels is necessary. The first plasma potassium check should be done during the first week of treatment.
If low potassium levels are found, their correction is required.
Calcium Levels
Thiazide and related diuretics can reduce urinary excretion of calcium and cause a slight and transient increase in plasma calcium levels. A marked increase in calcium levels may be related to undiagnosed hyperparathyroidism. In these cases, treatment should be stopped. before exploring the parathyroid function.
Glycemia
It is important, in diabetic patients, to check blood glucose especially in the presence of low potassium levels.
Uric acid
In hyperuricaemic patients, the tendency to gout attacks may increase.
Renal function and diuretics
Thiazide and related diuretics are fully effective only if renal function is normal or minimally impaired (creatinine levels below values of the order of 25 mg / l, or 220 mcmol / l in adults).
In the elderly, the value of plasma creatinine levels must be adjusted taking into account the age, weight and sex of the patient, according to the Cockroft formula:
C1cr = (140-age) x weight / 0.814 x blood creatinine
with: the age expressed in years
the weight expressed in Kg
the plasma creatinine value expressed in micromol / l
This formula is valid for elderly male subjects and must be corrected for women by multiplying the result by 0.85.
Hypovolemia, due to the loss of water and sodium caused by the diuretic at the start of treatment, causes a reduction in glomerular filtration. This can result in an increase in blood urea and creatinine levels. This transient functional renal insufficiency does not cause consequences in the patient with normal renal function, but can instead aggravate a pre-existing "renal insufficiency".

04.5 Interactions with other medicinal products and other forms of interaction
Common to perindopril and indapamide
Associations not recommended
Lithium: Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with ACE inhibitors. Concomitant use of thiazide diuretics may further increase lithium levels and increase the risk of lithium toxicity with ACE inhibitors. The combination of perindopril and indapamide with lithium is not recommended but if such a combination is necessary, a strict control of serum lithium levels (see section 4.4).
Associations that require special precautions for use
- Baclofen: Potentiation of the antihypertensive effect. Control of blood pressure and renal function and adjustment of the dose of the antihypertensive, if necessary
- Non-steroidal anti-inflammatory drugs (including high-dose acetylsalicylic acid): when ACE inhibitors are administered concomitantly with non-steroidal anti-inflammatory drugs (eg acetylsalicylic acid at anti-inflammatory dosage regimens, COX-2 inhibitors and non-NSAIDs selective), "attenuation of the antihypertensive effect" may occur. The concomitant use of ACE inhibitors and NSAIDs may lead to an increased risk of worsening of renal function, including acute renal failure, and to an increase in serum potassium, particularly in patients with pre-existing renal insufficiency; this combination should be administered with caution, particularly in elderly patients. Patients should be adequately hydrated and monitoring of renal function should be considered after initiation of concomitant therapy and periodically thereafter.
Associations to be monitored
- Imipramine-like antidepressants (tricyclics), neuroleptics: potentiation of the antihypertensive effect and potentiation of the risk of orthostatic hypotension (additive effect).
- Corticosteroids, tetracosactide: reduction of the antihypertensive effect (salt and water retention by corticosteroids)
- Other antihypertensives: the use of other antihypertensives with perindopril / indapamide could induce an additional blood pressure lowering effect.
Related to perindopril
Clinical trial data 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 adverse events. 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).
Associations not recommended
- Potassium-sparing diuretics (spironolactone, triamterene, alone or in combination), potassium salts: ACE inhibitors decrease the potassium loss induced by diuretics. Potassium-sparing diuretics, such as spironolactone, triamterene or amiloride, potassium supplements or potassium-containing salt substitutes can lead to significant increases in serum potassium (life-threatening). If concomitant use of these drugs is prescribed for the presence of documented hypokalaemia, they should be taken with caution and with frequent monitoring of serum potassium and by ECG.
Associations that need special precautions
- Antidiabetics (insulin, hypoglycemic sulfonamides): described for captopril and enalapril.
The use of angiotensin converting enzyme inhibitors may cause an enhancement of the blood glucose lowering effect in diabetic treated with hypoglycemic insulin or sulfonamides.The occurrence of hypoglycaemic episodes is very rare (improving glucose tolerance leads to a reduction in insulin requirements).
Associations to be monitored
- Allopurinol, cytostatics or immunosuppressive agents, systemic corticosteroids or procainamide: concomitant administration with ACE inhibitors may lead to an increased risk of leukopenia.
- Anesthetic drugs: ACE inhibitors can potentiate the hypotensive effect of some anesthetic drugs.
- Diuretics (thiazides or loop diuretics): previous treatment with high dose diuretics may lead to volume depletion and a risk of hypotension when initiating therapy with perindopril.
- Gold: Nitritoid reactions (symptoms include flushing of the face, nausea, vomiting and hypotension) have been reported rarely in patients receiving injectable gold (sodium aurothiomalate) and concomitant therapy with ACE inhibitors, including perindopril.
Related to indapamide
Associations that require special precautions for use
- Drugs that cause torsades de pointes: due to the risk of hypokalaemia, indapamide should be administered with caution in combination with drugs that induce torsades de pointes such as class IA antiarrhythmics (quinidine, hydroquinidine, disopyramide); class III antiarrhythmics (amiodarone, dofetilide, ibutilide, bretilium, sotalol); some neuroleptics (chlorpromazine, ciamemazine, levomepromazine, thioridazine, trifluoperazine), benzamides (amisulpride, sulpiride, sultopride, thiapride), butyroperzide (other pyroperzide), pyroperidrophols other substances such as bepridil, cisapride, dihemanyl, erythromycin IV, halofantrine, mizolastine, moxifloxacin, pentamidine, sparfloxacin, vincamine IV, methadone, astemizole, terfenadine. QT.
- Hypokalemic drugs: amphotericin B (iv route), glucocorticoids and mineralocorticoids (systemic route), tetracosactide, stimulant laxatives: potentiation of the risk of reduction of potassium levels (additive effect).
Control of potassium levels and possible correction; cases treated with digitalis require particular attention. Use non-stimulant laxatives.
- Digitalis: the reduction of potassium levels favors the toxic effects of digitalis. Monitoring of potassium levels and ECG is necessary and treatment should be reconsidered if necessary.
Associations to be monitored
- Metformin: lactic acidosis due to metformin triggered by a possible functional renal insufficiency linked to diuretics and more specifically to loop diuretics. Do not use metformin if plasma creatinine levels exceed 15 mg / liter (135 micromol / liter) in men and 12 mg / liter (110 micromol / liter) in women.
- Iodine contrast media: in the case of dehydration caused by diuretics, there is an increased risk of acute renal failure, particularly with high doses of iodinated contrast media. Rehydration should be performed prior to administration of the iodinated medium.
- Calcium (salts of): risk of an increase in calcium levels due to reduced elimination of calcium via the urine.
- Cyclosporine: risk of increased creatinine levels without changing the circulating rates of cyclosporine, even in the absence of salt and water depletion.
04.6 Pregnancy and breastfeeding
Given the effects of the individual components of this combination on pregnancy and lactation PRELECTAL 2.5 mg / 0.625 mg is not recommended during the first trimester of pregnancy. PRELECTAL 2.5 mg / 0.625 mg is contraindicated during the second and third trimester of pregnancy. .
PRELECTAL 2.5 mg / 0.625 mg is contraindicated during breastfeeding. A decision must therefore be made whether to discontinue breastfeeding or to discontinue PRELECTAL 2.5 mg / 0.625 mg taking into account the importance of this therapy for the mother.
Pregnancy
Related to perindopril
The use of ACE inhibitors is not recommended during the first trimester of pregnancy (see section 4.4). The use of ACE inhibitors is contraindicated during the second and third trimester 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. For patients planning to become pregnant, alternative antihypertensive treatments with a proven safety profile for use in pregnancy should be used unless continued therapy with an ACE inhibitor is considered essential. When pregnancy is diagnosed, treatment with ACE inhibitors should be stopped immediately and, if appropriate, alternative therapy should be started.
Exposure to ACE inhibitors during the second and third trimester of pregnancy 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 ACE inhibitor have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended.
Neonates whose mothers have taken ACE inhibitors should be carefully observed for hypotension (see sections 4.3 and 4.4).
Related to indapamide
Prolonged exposure to thiazide during the third trimester of pregnancy may reduce maternal plasma volume as well as uteroplacental blood flow which can result in fetal placental ischaemia and growth retardation. In addition, rare cases of hypoglycemia and thrombocytopenia have been reported in newborn infants. following exposure at the end of pregnancy.
Feeding time
PRELECTAL 2.5 mg / 0.625 mg is contraindicated during breastfeeding.
Related to perindopril
Since no data are available regarding the use of perindopril during lactation, perindopril is not recommended and alternative treatments with a proven safety profile for use during lactation are preferred, especially when nursing a newborn or preterm infant.
Related to indapamide
Indapamide is excreted in breast milk. Indapamide is very similar to thiazide diuretics which have been associated with decreased or even suppression of breast milk production during lactation. Hypersensitivity to sulfonamide-derived drugs, hypokalaemia and nuclear jaundice may occur.
04.7 Effects on ability to drive and use machines
Related to perindopril, indapamide and PRELECTAL 2.5 mg / 0.625 mg
The two components, alone or combined in PRELECTAL 2.5 mg / 0.625 mg, do not affect the ability to drive or use machines; however, individual reactions related to a drop in blood pressure may occur in some patients, especially at the start of treatment or at the time of association with another antihypertensive drug.
As a result, the ability to drive or use machines may be impaired.

Perindoprilat, the active metabolite of perindopril, is dialysable (see section 5.2).
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: perindopril and diuretics.
ATC code: C09BA04.
PRELECTAL 2.5 mg / 0.625 mg consists of the combination of perindopril arginine salt, an angiotensin converting enzyme inhibitor, and indapamide, a chlorosulfonamide diuretic. Its pharmacological properties derive from those of each of its components. to which are added the properties due to the synergistic action of the two associated products.
Mechanism of action
Related to PRELECTAL 2.5 mg / 0.625 mg
The antihypertensive effects of the two components add up synergistically in PRELECTAL 2.5 mg / 0.625 mg.
Related to perindopril
Perindopril is an inhibitor of the conversion enzyme (ACE) of angiotensin I to angiotensin II, a vasoconstrictor substance; furthermore, the angiotensin converting enzyme stimulates the secretion of aldosterone by the adrenal cortex and the degradation of bradykinin, a vasodilator substance, into an inactive heptapeptide.
It follows:
- a reduction in aldosterone secretion,
- an increase in plasma renin activity, since aldosterone no longer exerts a negative feedback,
- a decrease in total peripheral vascular resistance with a preferential activity at the muscle and renal level, not accompanied by salt and water retention or reflex tachycardia, in chronic treatment.
The antihypertensive action of perindopril also occurs in subjects with low or normal concentrations of renin.
Perindopril acts by means of its active metabolite, perindoprilat; the other metabolites are inactive.
Perindopril reduces the workload of the heart:
- with a venous vasodilatory effect, probably due to a change in prostaglandin metabolism: reduction of preload,
- with a reduction of the total peripheral resistances: reduction of the afterload.
Studies conducted in patients with heart failure have shown:
- a drop in left and right ventricular filling pressure,
- a reduction in total peripheral vascular resistance,
- an increase in cardiac flow and an improvement in the cardiac index,
- an increase in regional muscle blood flows.
Stress tests are also improved.
Related to indapamide
Indapamide is a sulfonamide derivative with an indole nucleus, pharmacologically related to the group of thiazide diuretics. Indapamide inhibits sodium reabsorption at the dilution cortical segment level. It increases the urinary excretion of sodium and chlorides and, to a lesser extent, the excretion of potassium and magnesium, thus increasing diuresis and exerting an antihypertensive action.
Pharmacodynamic effects
Related to PRELECTAL 2.5 mg / 0.625 mg
In hypertensive patients of any age, PRELECTAL 2.5 mg / 0.625 mg exerts a dose-dependent antihypertensive effect on diastolic and systolic blood pressure in the lying and standing position. The antihypertensive efficacy lasts for 24 hours. The blood pressure decrease is achieved in less than 1 month, without loss of efficacy; Discontinuation of treatment is not accompanied by rebound phenomena. The concomitant administration of perindopril and indapamide in clinical studies has demonstrated synergistic antihypertensive effects compared to the two products administered separately.
The effect of the reduced dose combination of PRELECTAL 2.5 mg / 0.625 mg on cardiovascular morbidity and mortality has not been studied.
PICXEL, a multicentre, randomized, double-blind, active-controlled study evaluated by echocardiography the effect of the combination perindopril / indapamide on left ventricular hypertrophy (IVS) compared to enalapril monotherapy.
In the PICXEL study, hypertensive patients with IVS (defined as left ventricular mass index (IMVS)> 120 g / m2 in men and> 100g / m2 in women) were randomized to perindopril tert-butylamine 2 mg (equivalent to 2 , 5 mg perindopril arginine) / indapamide 0.625 mg, or enalapril 10 mg, once daily for one year of therapy. The dose was titrated based on blood pressure values, up to perindopril tert-butylamine 8 mg (equivalent to 10 perindopril arginine) and indapamide 2.5 mg or enalapril 40 mg once daily. Only 34% of patients remained on perindopril tert-butylamine 2mg (equivalent to 2.5mg perindopril arginine) / indapamide 0.625 mg (versus 20% with enalapril 10 mg).
At the end of treatment, the left ventricular mass index (IMVS) decreased significantly in the perindopril / indapamide group (-10.1 g / m2) compared to the enalapril group (-1.1 g / m2) in the whole randomized patient population. The difference between groups on the change in left ventricular mass index (IMVS) was -8.3 (95% CI (-11.5, -5.0), p
A better effect on left ventricular mass index (IMVS) was achieved with higher doses of perindopril / indapamide than the doses of PRELECTAL 2.5 mg / 0.625 mg and PRELECTAL 5 mg / 1.25 mg.
For blood pressure, the estimated mean differences between groups in the randomized population were -5.8 mmHg (95% CI (-7.9, -3.7), systolic blood pressure and -2.3, respectively. mmHg (95% CI (-3.6, -0.9), p = 0.0004) for systolic blood pressure, in favor of the perindopril / indapamide group.
Related to perindopril
Perindopril is active at all stages of arterial hypertension: from mild to moderate up to severe. A reduction in systolic and diastolic blood pressure has been observed in supine and standing positions.
The peak of the antihypertensive effect occurs 4-6 hours after a single administration and the antihypertensive efficacy is maintained for at least 24 hours.
The residual inhibition of the angiotensin converting enzyme at the 24th hour is high and is around 80%.
In responding patients, blood pressure normalization is achieved after one month of treatment and is maintained without tachyphylaxis.
The suspension of treatment is not accompanied by rebound phenomena on hypertension.
Perindopril possesses vasodilatory and restorative properties of the elastic qualities of large arterial trunks, corrects structural changes in arterial resistance and determines a reduction in left ventricular hypertrophy.
If necessary, the addition of a thiazide diuretic produces additive synergy.
The combination of an angiotensin converting enzyme inhibitor and a thiazide diuretic also reduces the risk of hypokalaemia induced by the diuretic given alone.
Related to indapamide
Indapamide, alone, produces an antihypertensive effect that lasts for 24 hours; this effect occurs at doses at which the diuretic effect is not very evident.
Its antihypertensive activity is expressed through an improvement in arterial compliance and a reduction in total and arteriolar peripheral vascular resistance.
Indapamide reduces left ventricular hypertrophy.
Beyond a certain dose, there is a plateau of the antihypertensive effect of thiazide and related diuretics, with a simultaneous increase in undesirable effects; in case of ineffectiveness of the treatment, the dose should not be increased.
It has also been shown in the short, medium and long term in hypertension that indapamide:
- has no effect on lipid metabolism: triglycerides, LDL-cholesterol and HDL-cholesterol
- it has no effect on glucose metabolism, even in diabetic hypertensive patients
Clinical trial data on 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
Related to PRELECTAL 2.5 mg / 0.625 mg
The administration of the combination perindopril and indapamide does not modify the pharmacokinetic parameters of the two drugs taken separately.
Related to perindopril
Orally, the absorption of perindopril is rapid and the peak concentration is reached within one hour. The plasma half-life of perindopril is one hour.
Perindopril is a prodrug. 27% of the administered perindopril dose reaches the bloodstream as perindoprilat as the active metabolite. In addition to the active perindoprilat, perindopril produces five metabolites, all of which are inactive. The peak plasma concentration of perindoprilat is reached in 3-4 hours.
Since food intake reduces conversion to perindoprilat, and hence bioavailability, perindopril arginine should be administered orally in a single daily dose in the morning before a meal.
A linear correlation has been demonstrated between the dose of perindopril taken and the relative plasma concentration.
The volume of distribution of free perindoprilat is approximately 0.2 l / kg. Plasma protein binding of perindoprilat is 20%, mainly to angiotensin converting enzyme, but is concentration dependent.
Perindoprilat is eliminated in the urine and the final half-life of the free fraction is approximately 17 hours, with steady state attainment within 4 days.
Elimination of perindoprilat is reduced in the elderly, as well as in patients with heart or renal insufficiency. In renal insufficiency, dosage adjustment is desirable according to the degree of insufficiency (creatinine clearance).
The dialysis clearance of perindoprilat is 70ml / min.
In the cirrhotic patient, the kinetics of perindopril are changed: the hepatic clearance of the parent molecule is reduced by half. However, the amount of perindoprilat formed is not reduced and therefore no dosage adjustment is necessary (see sections 4.2 and 4.4).
Related to indapamide
Indapamide is rapidly and totally absorbed from the digestive tract.
The maximum plasma peak is reached in humans approximately one hour after oral administration of the drug. The plasma protein binding rate is 79%.
The elimination half-life is between 14 and 24 hours (average 18 hours). Repeated administrations do not cause accumulation. Elimination occurs essentially via the urine (70% of the dose) and faecal (22%) in the form of inactive metabolites.
Pharmacokinetic parameters do not change in the patient with renal insufficiency.
05.3 Preclinical safety data
PRELECTAL 2.5 mg / 0.625 mg has slightly higher toxicity than its components. Renal manifestations do not appear to be enhanced in the rat; however, the combination showed digestive toxicity in dogs and higher maternal toxic effects in rats (compared to perindopril).
These side effects, however, occurred at high doses, significantly higher than those used in therapy.
Preclinical studies conducted separately with perindopril and indapamide did not reveal any genotoxic, carcinogenic or teratogenic potential.
