Antirenin is a drug used in the treatment of benign and malignant tumors. It is also used to prevent this disease as it inhibits the formation of tumors in the body. Antirhein is a hormone that blocks the conversion of angiotensin I to angiotensin I, which reduces blood pressure. This reduces the risk of heart attacks, arrhythmias, myocardial infarction and other vascular diseases. If we talk about antirenin, it is injected intravenously or subcutaneously. After administration, the drug is not absorbed into the blood and its concentration in plasma decreases sharply. Antirenin is excreted within 3.5 hours.
