There is disclosed an improved long acting sustained release pharmaceutical composition for dihydropyridine calcium channel blockers wherein the calcium channel blocker and a pH-dependent binder, which are intimately admixed in essentially spherically shaped non-rugose particles of up to 1.2 mm in diameter, are provided with a coating to obtain slow, sustained release of a safe, therapeutically effective amount of the calcium channel blocker over a period of at least about 24 hours. Thus, the improved pharmaceutical composition for a dihydropyridine calcium channel blockers is suitable for once daily administration.
