Abstract
Abstract Pharmaceutical compositions which include in addition to the pharmaceutical ingredient or ingredients a water-insoluble, ionizable, partial salt of collagen or microcrystalline collagen. The composition may be in the form of a pourable liquid, a gel or ointment or a solid compressed tablet. The microcrystalline collagen colloidally dispersed in the liquid improves the stability of suspended ingredients in liquids and gels.
