Pharmacodynamics

Losartan is a specific angiotensin II (AT1) receptor antagonist. It does not inhibit kinase II, an enzyme that destroys bradykinin.

Reduces total peripheral vascular resistance, reduces afterload, and lowers systemic blood pressure. Lowers blood pressure in the small circle of blood circulation

Losartan is well absorbed in the gastrointestinal tract after oral use and undergoes initial metabolism during primary passage through the liver.

The bioavailability of losartan is about 33%. The drug does not accumulate in the body.

The half-life of losartan is 2 hours. Both losartan and its metabolite are highly bound to plasma proteins 92-99%. Losartan is excreted in the urine and bile.
