Abstract

Nifedipine is a potent Ca2+antagonist and is effective not only for vasospastic angina but also for stable-effort angina [1]. Nifedipine was initially supplied as a liquid-filled capsule formulation with rapid- but short-acting characteristics. The nifedipine capsule is generally administered every 8 h, however the administration of nifedipine t. i. d. cannot control episodes of the variant form of angina pectoris which occur early in the morning [2]. Adalat L (Bayer) was therefore developed for the purpose of producing a long-acting effect. It has been reported that 12 h after oral administration of 20 mg Adalat L, its plasma concentration was still higher than the minimal effective level[3].
