A combination pharmaceutical composition is described, together with the process for manufacturing said pharmaceutical composition wherein the active ingredients, namely triamterene and hydrochlorothiazide, are incorporated into a solid dosage form via a single wet granulation process utilizing an acid component. Said process simplifies the formulation and manufacturing, permits greater uniformity, and increases in vitro dissolution.
A novel pharmaceutical combination is described, together with a method of making the same and a method of treating hypertensive patients using the same, wherein (1) the pharmaceutically active antihypertensive agent and citric acid and (2) the pharmaceutically active antikaliuretic agent and a nonionic surfactant are mixed, either together or separately, to form an essentially homogenous combination composition, and only thereafter blending with excipients to form the novel combination composition in solid dosage form.
A long acting diltiazem formulation is disclosed that comprises more than 35 percent by weight of a swellable hydrophilic polymer. Release rate is also controlled by the application of diffusion controlled membrane to the matrix tablet containing swellable hydrophilic polymers. The diffusion rate through the membrane depends upon the composition or ratio of hydrophilic to hydrophobic coating agent.
Pharmaceutical compositions containing irbesartan, alone or in combination with a diuretic, providing tablets with a high relative amount of active agent and excellent wetting and disintegration properties.
