Corinfar and Kapoten are not complete analogues, each medication has its own peculiarities, therefore, a doctor should decide which antihypertensive agent is better, taking into account the patient’s state of health.
Pharmaceutical companies offer a wide range of drugs for the treatment of hypertension. These include Corinfar and Kapoten. Despite the general indications for use, medications have many differences that you need to know before starting a course of therapy.
Corinfar is available in prolonged round, biconvex, yellow tablets. They contain nifedipine as a therapeutic component.
In addition to it, the composition of the medicine includes:
- Milk sugar.
- Potato starch.
- Povidone K25.
- Propylene glycol.
- Titanium white.
Nifedipine is a selective calcium channel blocker . The drug has an antianginal and hypotensive effect, enhances blood supply in the kidneys and heart muscle, does not cause the phenomenon of “robbery”. The drug dilates the arteries, does not affect the tone of the veins. During therapy, the total peripheral vascular resistance, afterload, cardiac muscle tone, and its oxygen demand decrease.
The clinical effect after ingestion develops after 20 minutes, its duration in time takes from 4 to 6 hours. If the drug is drunk for 2-3 months, then it becomes addictive.
When ingested, up to 90% of the drunk dosage is absorbed . Bioavailability can vary from 50% to 70%, but with food it increases. In the liver, the drug is metabolized. The highest concentration after ingestion is achieved after 1-3 hours. Up to 95% of the drunk dosage binds to proteins.
The medication penetrates the placental and blood-brain barrier, is secreted through the mammary glands. Up to 20% is excreted through the intestines, the rest through the kidneys. The elimination half-life can vary from 2 to 5 hours , in patients with liver dysfunction it increases to 20 hours.
The drug is available in square tablets that have rounded edges. They are biconvex, on one side there is a cruciform notch. Slight marbling is allowed.
As an active ingredient, the medication contains captopril . In addition to it, the composition of the medicine includes inactive components:
- Milk sugar.
- Maize starch.
- Stearic acid.
Captopril is an ACE blocker . The drug suppresses the synthesis of angiotensin II, which causes vasoconstriction and increased blood pressure.
After taking captopril, afterload and OPSS, the production of aldosterone in the adrenal glands decreases. The maximum decrease in pressure is observed after 1-1.5 hours .
Captopril is rapidly adsorbed from the digestive tract, the highest concentration is noted after an hour. Bioavailability in different patients can vary from 60% to 70%. Up to 30% of the accepted dosage binds to blood proteins. Captopril is removed from the body mainly through the kidneys; the half-life varies from 2 to 3 hours .
