Abstract
The method of making a solid drug with controlled effective ingredient delivery for oral administration includes selecting a predetermined number of at least three of four compressed compositions containing an effective ingredient or effective ingredient combination defined by their release profile of effective ingredient and/or effective ingredient combination. The solid drug or medicinal preparation is formed according to known methods requiring only comparatively small apparatus expense and minimal time. Perorally administered solid drugs are made by this process which can provide widely varying pharmaceutically-required release profiles of effective ingredients or effective ingredient combinations, for example delayed release, uniformly maintained release or pulsatile release adjusted to fit a special rhythm.
