    摘要: This invention concerns systems for the release of active principles which are capable of releasing active principle(s) into an aqueous medium at a controlled rate.More precisely, the invention concerns a monolithic system for the controlled release of active principles, consisting of:a) at least one swelling layer containing one or more active principles, in a matrix of swellable, hydrophilic polymers;b) at least one erodible and/or soluble layer comprising excipients and/or water soluble polymers, possibly containing one or more active principles, either the same or different from those present in the layer a), the said erodible and/or soluble layer being in contact with the swelling layer(s) a).

    摘要: Pharmaceutically active compounds of the formula ##STR1## wherein --OR.sub.1, --OR.sub.2, --OR.sub.3 and --OR.sub.4, which may be the same or different, each represents a free or esterified hydroxyl group and --COOR.sub.5 represents a free or esterified carboxyl group, are provided together with processes for their production and pharmaceutical compositions containing them. Compounds of formula II and III possess valuable cicatrizing and anti-inflammatory properties.
