Title: Injectable medicinal compounds
IPC: A61K31/56
Filed: 1975-12-29
Abstract: A compound of the formula <IMAGE> is copolymerised with a compound containing two or more OH or COOH groups or at least one OH group and at least one COOH group in the presence of an acid catalyst and of a steroid compound. The pharmaceutical prepared in this way contains a mixture of the copolymer with the steroid compound.
