MISATEL - 40

Telmisartan is an angiotensin II receptor antagonist. Telmisartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow. Telmisartan is used to treat high blood pressure (hypertension). It is sometimes given together with other blood pressure medications.

Pharmacological Actions:
Telmisartan displaces angiotensin II with very high affinity from its binding site at the AT1 receptor subtype, which is responsible for the known actions of angiotensin II.

ABSORPTION:
Following oral administration of telmisartan, absorption is rapid (tmax ranges from 0.5 to 2 hours) although the amount absorbed varies. Absolute bioavailability of telmisartan was shown to be dose dependent. The mean absolute bioavailability of 40 mg telmisartan was 40%, whereas the mean absolute bioavailability of the 160 mg dose amounted to about 60%.
