Abstract
The invention relates to a novel method of producing slow-release pharmaceutical forms administered per os, by simultaneously employing two resins having anionic character, the proportions of said resins being variable. By varying the ratio of the amounts of active principles on the respective two resins, it is possible to modify the release kinetics of active principle; and by independently varying the amount of carboxylic resin it is possible to produce stabile pharmaceutical preparations which are in liquid, semi-liquid, or solid form.
