ENTERIC COATED DILTIAZEM ONCE-A-DAY FORMULATION

摘要

A once-a-day diltiazem dosage form which comprises: (a) a core element which is a compressed tablet which contains a therapeutic dose of diltiazem and an amount of a solubility modulating substance that controls the release of said diltiazem in order to provide a therapeutic level over a period of about 24 hours; and (b) on the outer surface of the core element, a sufficient amount of an enteric coating that causes the diltiazem to release at a rate that permits the use of once-a-day dosing to maintain steady state therapeutic levels of diltiazem.
