Active ingredients: Olmesartan medoxomil
OLMETEC 10mg, 20mg, 40mg film-coated tablets
Indications Why is Olmetec used? What is it for?
Olmetec belongs to a group of medicines called angiotensin II receptor antagonists. They lower blood pressure by releasing blood vessels.
Olmetec is used to treat high blood pressure (also called "high blood pressure"). High blood pressure can damage blood vessels in organs such as the heart, kidney, brain and eye. In some cases, this can lead to heart attacks, heart or kidney failure, stroke, or blindness. Usually, high blood pressure does not have symptoms. It is important to check your blood pressure to prevent damage.
High blood pressure can be controlled with medicines such as Olmetec tablets. Your doctor has probably also recommended that you make some lifestyle changes to help lower your blood pressure (for example, lose weight, quit smoking, reduce alcohol intake, and reduce dietary salt intake. ). Your doctor may also have advised you to exercise regularly, such as walking or swimming. It is important that you follow these advice from your doctor.
Contraindications When Olmetec should not be used
Do not take Olmetec
- if you are allergic to olmesartan medoxomil or any of the other ingredients of this medicine (listed in section 6).
- if you are more than three months pregnant (it is also better to avoid Olmetec in early pregnancy - see "Pregnancy" section).
- if you suffer from yellowing of the skin and eyes (jaundice) or from changes in the outflow of bile from the gallbladder (biliary obstruction, for example stones).
- 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 Olmetec
Warnings and precautions Talk to your doctor before taking Olmetec.
Consult your doctor if you are taking any of the following medicines used to treat high blood pressure:
- an ACE inhibitor (for example enalapril, lisinopril, ramipril), particularly if you have diabetes-related kidney problems.
- Aliskiren
Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (such as potassium) in your blood at regular intervals.
See also information under the heading "Do not take Olmetec"
Consult your doctor if you also have any of the following health problems:
- Kidney problems.
- Liver disease.
- Heart failure or problems with your heart valves or heart muscle.
- Severe vomiting, diarrhea, treatment with high doses of diuretics or if you are on a low-salt diet.
- Increased levels of potassium in the blood.
- Problems with the adrenal glands.
Tell your doctor if you experience severe and prolonged diarrhea with significant weight loss. Your doctor will evaluate your symptoms and decide whether to continue this antihypertensive treatment.
As with any medicine that lowers blood pressure, too much blood pressure reduction in patients with circulatory disorders of the heart or brain could lead to a heart attack or stroke. Your doctor will then check your blood pressure carefully.
You should tell your doctor if you think you are pregnant (or if there is a possibility of becoming pregnant). Olmetec is not recommended in early pregnancy and must not be taken if you are more than three months pregnant, as it may cause serious harm to your baby if used at that stage (see "pregnancy" section).
Children and adolescents
Olmetec is not recommended for children and adolescents under 18 years of age.
Interactions Which drugs or foods can change the effect of Olmetec
Other medicines and Olmetec
Tell your doctor or pharmacist if you are taking, have recently taken or might also take any of the following medicines:
- Other medicines that lower blood pressure may increase the effect of Olmetec. Your doctor may need to adjust the dose and / or take other precautions: If you are taking an ACE inhibitor or aliskiren (see also information under "Do not take Olmetec" and "Warnings and Precautions".
- Potassium supplements, salt substitutes that contain potassium, diuretics or heparin (to thin the blood). The use of these medicines taken together with Olmetec can increase the levels of potassium in the blood.
- Lithium (a medicine used to treat mood swings and some types of depression) used together with Olmetec can increase the toxicity of lithium. If you have to take lithium, your doctor will measure your lithium blood levels.
- Non-steroidal anti-inflammatory drugs (NSAIDs, medicines used to decrease pain, swelling and other symptoms of inflammation, including arthritis) used together with Olmetec may increase the risk of kidney failure and the effectiveness of Olmetec may be reduced by NSAIDs .
- Colesevelam hydrochloride, a medicine that reduces cholesterol levels in the blood, which may decrease the effect of Olmetec. Your doctor may advise you to take Olmetec at least 4 hours before colesevelam hydrochloride.
- Some antacids (used for indigestion) may slightly reduce the effectiveness of Olmetec.
Older people
If you are over 65 years of age and your doctor decides to increase your dose of olmesartan to 40 mg per day, your blood pressure should be regularly checked by your doctor to prevent it from falling too low.
Patients of black ethnicity
As with other similar medicines, the blood pressure lowering effect of Olmetec is somewhat reduced in black patients.
Taking Olmetec with food and drink
Olmetec can be taken on a full or empty stomach.
Warnings It is important to know that:
Pregnancy and breastfeeding
Pregnancy
You should tell your doctor if you think you are pregnant (or if there is a possibility of becoming pregnant). As a rule, your doctor will advise you to stop taking Olmetec before becoming pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Olmetec. Olmetec is not recommended for all early pregnancy and should not be taken if you are more than three months pregnant as it may cause serious harm to your baby if taken after the third month of pregnancy.
Feeding time
Tell your doctor if you are breastfeeding or about to start breastfeeding. Olmetec is not recommended for women who are breastfeeding, and your doctor may choose another treatment for you if you wish to breastfeed, especially if your baby is just born or premature birth Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
You may feel sleepy or dizzy while being treated for high blood pressure. If this happens, do not drive or use machines until the symptoms have disappeared. Ask your doctor for advice.
Olmetec contains lactose
This medicine contains lactose (a type of sugar). If you have been told by your doctor that you have an "intolerance to some sugars, contact your doctor before taking this medicine.
Dose, Method and Time of Administration How to use Olmetec: Posology
Always take this medicine exactly as your doctor has told you. If you are unsure, consult your doctor or pharmacist.
The recommended starting dose is one 10 mg tablet once a day. However, if your blood pressure is not controlled, your doctor may decide to increase the dose to 20 or 40 mg once a day, or he may prescribe other medicines. In patients with mild to moderate renal impairment, the dose should not exceed 20 mg once daily.

04.2 Posology and method of administration
Dosage
Adults
The recommended starting dose of olmesartan medoxomil is 10 mg once daily. In patients for whom this dosage does not ensure adequate blood pressure control, the dose of olmesartan medoxomil can be increased to 20 mg once daily as the optimal dose. If further reduction in blood pressure is required, the dose of olmesartan medoxomil can be further increased to a maximum of 40 mg per day or combined with hydrochlorothiazide therapy.
The antihypertensive effect of olmesartan medoxomil is substantially achieved within 2 weeks of initiation of therapy and reaches its maximum level within approximately 8 weeks of initiation of treatment. These data should be taken into account when planning dose adjustments for any patient.
Older people (65 years or older)
Dosage adjustments are generally not required in elderly people (see below for dosage recommendations in patients with impaired renal function). If administration of the maximum dose of 40 mg per day is required, blood pressure should be carefully monitored.
Altered kidney function
The maximum dosage in patients with mild or moderate renal impairment (creatinine clearance between 20 and 60 ml / min) is 20 mg olmesartan medoxomil once daily due to limited clinical experience with higher doses in this patient group. . The use of olmesartan medoxomil in patients with severe renal impairment (creatinine clearance less than 20 ml / min) is not recommended due to limited clinical experience in this patient group (see sections 4.4 and 5.2).
Altered liver function
No dosage adjustments are required for patients with mild hepatic impairment. In patients with moderate hepatic impairment, the recommended starting dose of olmesartan medoxomil is 10 mg once daily and the maximum dose should not exceed 20 mg once daily. In patients with hepatic impairment taking diuretics and / or other antihypertensive drugs, careful monitoring of blood pressure and renal function is advised. There is no experience of the use of olmesartan medoxomil in patients with severe hepatic impairment, therefore use in this patient group is not recommended (see sections 4.4 and 5.2). Olmesartan medoxomil must not be used in patients with biliary obstruction (see section 4.3).
Pediatric population
The safety and efficacy of Olmetec in children and adolescents below 18 years of age have not been established. There are no data available.
Method of administration
For better compliance, it is recommended to take the OLMETEC tablets every day at approximately the same time, either on an empty stomach or on a full stomach, for example with breakfast. The tablets should be swallowed with a sufficient amount of liquid (eg a glass of water). The tablets should not be chewed.
04.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients (listed in section 6.1).
Second and third trimester of pregnancy (see sections 4.4 and 4.6).
Biliary obstruction (see section 5.2).
04.4 Special warnings and appropriate precautions for use
Intravascular volume depletion
In patients with hypovolaemia and / or sodium depletion caused by high doses of diuretics, reduced dietary sodium intake, diarrhea or vomiting, symptomatic hypotension may occur, especially after the first dose. These conditions must be corrected before starting treatment with olmesartan medoxomil.
Other conditions related to stimulation of the renin-angiotensin-aldosterone system
In patients whose vascular tone and renal function are primarily 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 other drugs that affect this system it has been associated with acute hypotension, azotemia, oliguria or, in rare cases, acute renal failure. The possibility of similar effects cannot be excluded with angiotensin II receptor antagonists.
Renovascular hypertension
In patients with bilateral renal artery stenosis, or stenosis of the afferent artery to a single functioning kidney, treated with drugs that affect the renin-angiotensin-aldosterone system, there is an increased risk of severe hypotension and renal failure.
Impaired renal function and renal transplant
If olmesartan medoxomil is administered to patients with impaired renal function, periodic monitoring of serum potassium and creatinine levels is recommended. The use of olmesartan medoxomil is not recommended in patients with severe renal impairment (creatinine clearance less than 20 ml / min) (see sections 4.2, 5.2). There is no experience of the administration of olmesartan medoxomil in patients recently undergoing kidney transplantation or in patients with end stage renal insufficiency (creatinine clearance
Altered liver function
There is no experience in patients with severe hepatic impairment, and therefore the use of olmesartan medoxomil is not recommended in this patient group (see section 4.2 for dose adjustments in patients with mild or moderate hepatic impairment).
Hyperkalaemia
The use of drugs that affect the renin-angiotensin-aldosterone system can lead to hyperkalaemia. The risk, which can be fatal, is increased in the elderly, in patients with renal insufficiency, in diabetics, in patients taking concomitant other drugs in able to increase potassium and / or in patients with intercurrent events.
Before considering the concomitant use of drugs affecting the renin-angiotensin-aldosterone system, the benefit-risk ratio should be assessed and other options considered.
The main risk factors to consider for hyperkalaemia are:
- Diabetes, renal impairment, age (> 70 years)
- Association with one or more drugs that affect the renin-angiotensin-aldosterone system and / or potassium supplements. Certain drugs or therapeutic classes of drugs can cause hyperkalaemia: potassium-containing salt substitutes, potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists, non-steroidal anti-inflammatory drugs (including selective COX-2 inhibitors), heparin, immunosuppressants such as cyclosporine or tacrolimus, trimethoprim
- Intercurrent events, in particular dehydration, acute heart failure, metabolic acidosis, worsening of kidney function, sudden worsening of kidney conditions (e.g. infections), cell lysis (e.g. acute limb ischaemia, rhabdomyolysis, extensive trauma)
In patients at risk, careful monitoring of serum potassium levels should be performed (see section 4.5).
Lithium
As with other angiotensin II antagonists, the combination of lithium and olmesartan medoxomil is not recommended (see section 4.5).
Stenosis of the aortic or mitral valve; obstructive hypertrophic myocardiopathy
As with other vasodilators, special caution is recommended in patients with aortic or mitral valve stenosis or obstructive hypertrophic cardiomyopathy.
Primary aldosteronism
Patients with primary aldosteronism generally do not respond to antihypertensive drugs acting by inhibition of the renin-angiotensin system. Therefore, the use of olmesartan medoxomil is not recommended in the treatment of these patients.
Ethnic differences
As with all other angiotensin II antagonists, the antihypertensive effect of olmesartan medoxomil may be less in black patients, possibly due to the higher prevalence of low renin levels in the black hypertensive population.
Pregnancy
Therapy with angiotensin II receptor antagonists should not be initiated during pregnancy. Alternative antihypertensive treatments with a proven safety profile for use in pregnancy should be used for patients planning to become pregnant, unless continued therapy with an angiotensin II receptor antagonist is considered essential. When pregnancy is diagnosed, treatment with angiotensin II receptor antagonists should be stopped immediately and, if appropriate, alternative therapy should be started (see sections 4.3 and 4.6).
Other
As with any antihypertensive agent, an excessive decrease in blood pressure in patients with ischemic heart disease or ischemic cerebrovascular disease can cause myocardial infarction or stroke.
This drug contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp-lactase deficiency or glucose-galactose malabsorption should not take this drug.
04.5 Interactions with other medicinal products and other forms of interaction
Interaction studies have only been performed in adults.
Effects of other medicinal products on olmesartan medoxomil
Potassium supplements and potassium-sparing diuretics
Clinical experience indicates that the use of other drugs that affect the renin-angiotensin system in combination with potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes or other drugs capable of increasing serum potassium levels (eg heparin) may cause an increase in serum potassium (see section 4.4). Such concomitant use is therefore not recommended.
Other antihypertensive drugs
The hypotensive effect caused by olmesartan medoxomil may be potentiated by the concomitant use of other antihypertensive drugs.
Non-steroidal anti-inflammatory drugs (NSAIDs)
NSAIDs (including acetylsalicylic acid at doses> 3 g / day and COX-2 inhibitors) and angiotensin II receptor antagonists may act synergistically by reducing glomerular filtration. The risk of concomitant use of NSAIDs and angiotensin II antagonists is acute renal failure. It is recommended to monitor renal function at the start of treatment and to hydrate the patient regularly.
Furthermore, concomitant treatment may reduce the antihypertensive effect of angiotensin II receptor antagonists, leading to their partial loss of efficacy.
Other drugs
After treatment with antacids (magnesium aluminum hydroxide), a modest reduction in the bioavailability of olmesartan was observed. Concomitant administration of warfarin and digoxin has no effect on the pharmacokinetics of olmesartan.
Effects of olmesartan medoxomil on other medicinal products
Lithium
Reversible increases in serum lithium concentrations and its toxicity have been reported during administration of lithium in combination with angiotensin converting enzyme inhibitors and angiotensin II antagonists. Therefore, the use of olmesartan medoxomil and lithium in combination is not recommended (see section 4.4). If the use of this combination is deemed necessary, careful monitoring of serum lithium levels is recommended.
Other drugs
Warfarin, digoxin, an antacid (magnesium aluminum hydroxide), hydrochlorothiazide and pravastatin were studied in specific clinical studies conducted in healthy volunteers. No relevant clinical interactions were observed and, in particular, olmesartan medoxomil had no significant effect on the pharmacokinetics or pharmacodynamics of warfarin or on the pharmacokinetics of digoxin.
Olmesartan has no clinically relevant inhibitory effects on human cytochrome P450 enzymes 1A1 / 2, 2A6, 2C8 / 9, 2C19, 2D6, 2E1 and 3A4 in vitro, while induction effects on rat cytochrome P450 are minimal or absent. Therefore, no in vivo interaction studies have been performed with known cytochrome P450 inhibitors and enzyme inducers, and clinically relevant interactions between olmesartan and drugs metabolised by the aforementioned cytochrome P450 enzymes are not expected.
04.6 Pregnancy and lactation
Pregnancy
The use of angiotensin II receptor antagonists is not recommended during the first trimester of pregnancy (see section 4.4). The use of angiotensin II receptor antagonists 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 controlled epidemiological data on the risk with angiotensin II receptor antagonists are not available, a similar risk may also exist for this class of drugs.. Alternative antihypertensive treatments with a proven safety profile for use in pregnancy should be used for patients planning pregnancy unless continued angiotensin II receptor antagonist therapy is considered essential. When pregnancy is diagnosed, treatment with angiotensin II receptor antagonists should be stopped immediately, and, if appropriate, alternative therapy should be started.
In women, exposure to angiotensin II receptor antagonists 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) (see also section 5.3 "Preclinical safety data").
Should exposure to an angiotensin II receptor antagonist have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended.
Neonates whose mothers have taken angiotensin II receptor antagonists should be closely monitored for hypotension (see also sections 4.3 and 4.4).
Feeding time
Olmesartan is excreted in the breast milk of rats, but it is not known whether the same occurs in human milk. As no data are available regarding the use of Olmetec during lactation, Olmetec 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.
04.7 Effects on ability to drive and use machines
Olmetec has a mild or moderate influence on the ability to drive and use machines. Dizziness or symptoms of fatigue, which may impair the ability to react, may occasionally occur in patients on antihypertensive therapy.
04.8 Undesirable effects
Summary of the safety profile
The most commonly reported adverse reactions during treatment with Olmetec are headache (7.7%), flu-like symptoms (4.0%) and dizziness (3.7%).
In the placebo-controlled monotherapy studies, the only unequivocal adverse reaction related to treatment was dizziness (2.5% incidence with olmesartan medoxomil and 0.9% with placebo). The incidence was also somewhat higher with olmesartan medoxomil compared to placebo for hypertriglyceridaemia (2.0% versus 1.1%) and for the increase in creatine phosphokinase (1.3% versus 0, 7%).
Tabulated list of adverse reactions
The following table summarizes the adverse reactions from Olmetec observed in clinical studies, post-registration safety studies and spontaneously reported.
The following terminology has been used to classify the frequency of adverse reactions: very common (≥1 / 10); common (≥1 / 100,
Single cases of rhabdomyolysis have been reported in temporal association with the intake of angiotensin II receptor blockers.
Additional information on special populations
In older people, the frequency of hypotension is slightly increased from rare to uncommon.
Reporting of suspected adverse reactions
The reporting of suspected adverse reactions occurring after authorization of the medicinal product is important, as it allows continuous monitoring of the benefit / risk ratio of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions to their Territorial Reference Center for Pharmacovigilance or through the Italian Medicines Agency.
04.9 Overdose
Only limited data are available regarding overdose in humans. The most likely effect of overdose is hypotension. In the event of an overdose, the patient should be closely monitored and treatment should be symptomatic and supportive.
There are no data on the dialysability of olmesartan.
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group:
Angiotensin II antagonists, ATC code: C09CA08.
Mechanism of action / Pharmacodynamic effects
Olmesartan medoxomil is a potent orally effective selective angiotensin II receptor antagonist (type AT1). Its effect is to block all AT1 receptor-mediated angiotensin II activities, regardless of origin and route of synthesis. "angiotensin II. Selective angiotensin II receptor antagonism (AT1) produces an increase in plasma renin levels and angiotensin I and II concentrations and a decrease in plasma aldosterone concentrations.
Angiotensin II is the main vasoactive hormone of the renin-angiotensin-aldosterone system and plays a significant role in the pathophysiology of hypertension by means of the type 1 receptor (AT1).
Clinical efficacy and safety
In cases of hypertension, olmesartan medoxomil results in a dose-dependent, long-term reduction in blood pressure. There are no reports of hypotension after the first administration, of tachyphylaxis during prolonged treatments or of rebound hypertension on discontinuation of therapy.
The once-a-day administration of olmesartan medoxomil ensures an effective and constant reduction of blood pressure in the 24-hour interval between one dose and the next. With the same overall dosage, once-daily administration produced the same results in decreasing blood pressure. compared to administering the drug twice a day.
With continued treatment, the maximum reduction in blood pressure is achieved within 8 weeks following the initiation of therapy, although a substantial decrease in blood pressure is already observed after 2 weeks of treatment. When used in combination with hydrochlorothiazide, a "further decrease in blood pressure and co-administration is well tolerated.
The effects of olmesartan on mortality and morbidity are currently unknown.
05.2 "Pharmacokinetic properties
Absorption and distribution
Olmesartan medoxomil is a pro-drug rapidly converted to a pharmacologically active metabolite, olmesartan, by esterases in the intestinal mucosa and portal circulation during absorption from the gastrointestinal tract. There is no trace of intact olmesartan medoxomil or the intact medoxomil side chain in plasma. or excreta The mean absolute bioavailability of olmesartan, in the tablet formulation, was 25.6%.
The mean peak plasma concentration (Cmax) of olmesartan is achieved on average within approximately 2 hours after oral administration of olmesartan medoxomil; Plasma concentrations of olmesartan increase approximately linearly as the single oral dose increases to approximately 80 mg.
Food administration has minimal effects on the bioavailability of olmesartan and, therefore, olmesartan medoxomil can be administered in the fasted or fed state.
No clinically relevant differences in the pharmacokinetics of olmesartan dependent on patient sex were observed.
Olmesartan is strongly bound to plasma proteins (99.7%), but the potential for clinically significant protein binding displacement interactions between olmesartan and other co-administered highly bound drugs is low (as confirmed by the "absence of a" clinically significant interaction between olmesartan medoxomil and warfarin). The binding of olmesartan to blood cells is negligible. The mean volume of distribution after intravenous administration is small (16-29 l).
Biotransformation and elimination
Total plasma clearance was 1.3 l / h (CV 19%), relatively low when compared to hepatic flow (approx. 90 l / h). Following a single oral dose of 14C-labeled olmesartan medoxomil, 10-16% of the administered radioactivity was excreted in the urine (largely within 24 hours following administration), while the remaining radioactivity was eliminated with the feces. Based on a systemic bioavailability of 25.6%, it can be estimated that absorbed olmesartan is eliminated by renal (approximately 40%) and hepatobiliary (approximately 60%) excretion. All recovered radioactivity was identified as olmesartan No other significant metabolites identified. The enterohepatic circulation of olmesartan is minimal. Since a large amount of olmesartan is eliminated via the biliary route, use in patients with biliary obstruction is contraindicated (see section 4.3).
The terminal elimination half-life of olmesartan varies between 10 and 15 hours after repeated oral administration. Steady state was reached after the first few administrations and no further accumulation was detected after 14 days of repeated administration. Clearance renal rate was approximately 0.5-0.7 L / h and was independent of the dose.
Pharmacokinetics in special patient groups
Older people (65 years of age or older)
In hypertensive patients, steady state AUC was approximately 35% higher in older people (65 to 75 years old) and about 44% higher in very old people (≥ 75 years old) than in younger patients This may be due, at least in part, to a mean decrease in renal function in this patient group.
Altered kidney function
In cases of renal impairment, steady state AUC was 62%, 82% and 179% higher in patients with mild, moderate and severe renal impairment, respectively, compared to subjects with normal renal function (see sections 4.2 and 4.4 ).
Altered liver function
After single oral administration, the AUC values of olmesartan were 6% and 65% higher, respectively, in patients with mild and moderate hepatic impairment compared to subjects with normal hepatic function. The unbound fraction of olmesartan two hours after dosing was 0.26% in healthy subjects, 0.34% in patients with mild hepatic impairment and 0.41% in those with moderate hepatic impairment. Following repeated dosing in patients with moderate hepatic impairment, the mean AUC of olmesartan was still approximately 65% higher than in healthy controls. The mean C values of olmesartan were similar in patients with impaired hepatic function and in the healthy subjects Olmesartan medoxomil has not been studied in patients with severe hepatic impairment (see sections 4.2 and 4.4).
05.3 Preclinical safety data
In chronic toxicity studies in rats and dogs, olmesartan medoxomil showed similar effects to other ACE inhibitors and AT1 receptor antagonists: increased urea nitrogen (BUN) and creatinine (due to functional changes in the kidney caused by receptor blockade AT1); weight reduction of the heart; reduction of erythocitrar parameters (erythrocytes, hemoglobin, hematocrit); histological indications of renal damage (regenerative lesions of the renal epithelium, thickening of the basement membrane, dilation of the tubules). These adverse effects caused by the pharmacological action of olmesartan medoxomil have also occurred during preclinical trials on other ACE inhibitors and AT1 receptor antagonists and can be reduced by the simultaneous administration of sodium chloride.
In both species, increased plasma renin activity and hypertrophy / hyperplasia of renal juxtaglomerular cells were observed. These changes, which represent a typical effect of the class of ACE inhibitors and other AT1 receptor antagonists, do not seem to be of relevance. clinic.
Like other AT1 receptor antagonists, olmesartan medoxomil causes an increased incidence of chromosomal breaks in in vitro cell cultures. No relevant effects have been observed in numerous in vivo studies in which olmesartan medoxomil was administered at very high oral doses up to 2000. mg / kg Overall data from genotoxicity tests suggest that olmesartan is very unlikely to exhibit genotoxic effects under conditions of clinical use.
Olmesartan medoxomil was not carcinogenic, neither in rats in 2-year studies nor in mice studied in two 6-month carcinogenicity studies using transgenic models.
In reproduction studies in rats, olmesartan medoxomil did not impair fertility and there was no indication of teratogenic effects. Like other angiotensin II antagonists, offspring survival was reduced following exposure to olmesartan medoxomil and dilation of the renal pelvis was observed following exposure of females during late pregnancy and during pregnancy. feeding time. As with other antihypertensive agents, olmesartan medoxomil showed a higher toxic potential in rabbits than in pregnant rats. However, no indications of foetotoxic effects were found.
