Abstract

A peroral depot medicament with controlled active substance release is composed of a gelatine matrix that continuously dissolves in an aqueous medium above 37.degree.

The release of the medicament, that may be easily or scarcely soluble, lipophilic or hydrophilic, is variable in time and may be adjusted according to the medicament.
