23 An Erosion-Controlled Active Agent Release System and a Process for its Preparation Abstract The invention relates to a system for preferably peroral ad- ministration with erosion-controlled active agent release and a process for its preparation from which preferably low solubility active agents are released with delay, and in a possible combination of suitable, high solubility active agents the latter are released rapidly and with only slight delay. The active agent(s) is (are) fabricated in the usual manner with adjuvants capable of swelling, e.g. micro- crystalline cellulose or starch, with adjuvants which have higher affinity to water and function as swelling con- trollers (e.g. polyethylene glycols, strongly hydrating in- organic compounds) and optionally with additional adjuvants. The pharmaceutical preparations prepared in this manner con- tribute significantly to improving the therapy of various illnesses, for when suitable and preferably low solubility active agents are incorporated, the adjustment and main- tenance of therapeutically effective concentrations of active agent are ensured.
