A dosage form comprising of a high dose, high soly. active ingredient as modified release and a low dose active ingredient as immediate release where the wt. ratio of immediate release active ingredient and modified release active ingredient is from 1:10 to 1:15000 and the wt. of modified release active ingredient per unit is from 500 mg to 1500 mg; a process for prepg. the dosage form. An inner portion contained pravastatin sodium, lactose monohydrate, starch, Mg stearate, Na starch glycolate and dye to make tablets. An outer portion contained niacin, Eudragit RSPO to form granules and they were coated with hydrogenated castor oil in acetone and mixed with Mg stearate. Tablets were prepd. by compression such that the resultant tablets have an inner portion covered by the outer portion from all sides except the top surface that remains uncovered and the level of the inner portion and the outer portion is on the same surface.
