Contraindications
- Stenosis of the aortic mouth with severe hemodynamic disturbances;
- Severe liver failure (above 9 points on the Child-Pugh scale);
- Shock;
- Severe arterial hypotension;
- Age up to 18 years;
- Pregnancy and breastfeeding period;
- Hypersensitivity to the components of the drug.
It is recommended to prescribe Amzaar with caution: to patients on a diet that limits salt intake, with hyperkalemia, renal failure (creatinine clearance (CC) less than 20 ml/min) or hemodialysis, liver failure (below 9 points on the Child-Pugh scale), arterial hypotension, mitral stenosis, aortic stenosis, sick sinus syndrome (SSNS) (tachycardia, severe bradycardia), hypertrophic obstructive cardiomyopathy, chronic heart failure of non-ischemic origin (II-IV functional class according to the NYHA classification), acute myocardial infarction (and during 4 weeks after it), with a reduced circulating blood volume (CBV) associated with taking high doses of diuretics, severe diarrhea, vomiting and other conditions causing hypovolemia in old age.
Directions for use and dosage
The tablets are taken orally 1 time per day with a small amount of water, regardless of meals.
The use of Amzaar should be started after preliminary titration of the doses of losartan and amlodipine. If necessary, you can switch to combination therapy from taking losartan or amlodipine separately.
When switching from simultaneous use of losartan and amlodipine, the dose of the drug is prescribed in accordance with the doses of the previous monotherapy.
The use of tablets is indicated for patients in whom similar doses of losartan (50 mg) or amlodipine (5 mg) do not sufficiently control blood pressure (BP).
In case of renal failure with CC 20-50 ml/min, patients do not require dose adjustment. When CC is less than 20 ml/min and hemodialysis, it is necessary to adjust the doses of the active components of the drug; prescribing Amzaar in this case is not recommended.
In patients taking diuretics in high doses, taking the drug is possible if sufficient volume replenishment is ensured, but only if it is not necessary to reduce the dose of losartan to 25 mg.
In case of liver failure (below 9 points on the Child-Pugh scale), the use of the drug is allowed if, in the opinion of the doctor, it is possible to prescribe losartan at a dose of 50 mg.
Over the age of 65 years, the drug is prescribed to patients with adequate tolerance to a dose of losartan 50 mg.
