Abstract

A bilayer tablet comprises a first layer formulated for instant release of the angiotensin II receptor antagonist telmisartan from a dissolving tablet matrix and a second layer formulated for instant release of the calcium channel blocker amlodipine from a disintegrating or eroding tablet matrix.

Description

[0001] The present invention relates to a first layer comprising the angiotensin II receptor antagonist telmisartan in a dissolving tablet matrix and a second layer of the calcium ion channel blocker amlodipine in a disintegrating or eroding tablet matrix. Layers of medicine tablets. Background of the invention [0002] As disclosed in EP-A-502314, Telmisartan is an angiotensin II receptor antagonist developed for the treatment of hypertension and other medical indications. Its chemical name is 4'-[2-n-propyl-4-methyl-6-(1-methylbenzimidazol-2-yl)-benzimidazol-1-ylmethyl]- Biphenyl-2-carboxylic acid; [0003] [0004] Telmisartan is manufactured and supplied in the free acid form. It is characterized by very poor solubility in aqueous systems of the gastrointestinal tract in the physiological pH range between pH 1 and pH 7. As disclosed in WO 00 / 43370, crystalline telmisartan exists in two polymorphic forms with different melting points. Under the influence of heat and ...
