Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in a number of tissues. It does not cause persistent dry cough that normally complicates ACE inhibitors therapy. This is due to the fact that it does not inhibit the breakdown of Kinins. Pharmacokinetics: Telmisartan is rapidly absorbed from the gastrointestinal tract; the absolute oral bio availability is dose dependent and is about 42%f ollowing a 40mg dose and 58% following a 160mg dose. Peak plasma concentrations of Telmisartan are reached about 0.5 to 1 hour after oral dose. Telmisartan is over 99 % bound to plasma proteins. It is excreted almost entirely in faeces via bile, mainly as unchanged drug. The terminal elimination half-life of Telmisartan is about 24 hours.
Hypertension Treatment of essential hypertension in adults. Cardiovascular prevention Reduction of cardiovascular morbidity in adults with: manifest atherothrombotic cardiovascular disease (history of coronary heart disease, stroke, or peripheral arterial disease) or type 2 diabetes mellitus with documented target organ damage.
DOSAGE AND ADMINISTRATION:
The usual starting dose of Telmisartan is 40mg once a day;blood pressure response is dose related over the range of 20-80 mg. Patients with depletion of intravascular volume should have the condition corrected or Telmisartan tablets should be initiated under close medical supervision.
Posology and Method of Administration Treatment of essential hypertension The usually effective dose is 40 mg once daily. Some patients may already benefit at a daily dose of 20 mg. In cases where the target blood pressure is not achieved, the dose of telmisartan can be increased to a maximum of 80 mg once daily. Alternatively, telmisartan may be used in combination with thiazide-type diuretics such as hydrochlorothiazide, which has been shown to have an additive blood pressure lowering effect with telmisartan. Cardiovascular prevention The recommended dose is 80 mg once daily. Elderly patients No dose adjustment is necessary for elderly patients. Paediatric population The safety and efficacy of Telmisartan in children and adolescents aged below 18 years have not been established.
