Method for preparing a stable aqueous dispersion of a Copolymer, Frozen, and a water soluble Drug. (breakdown and priority of the Spanish Patent no. 544.580 submitted on 26 June 1985).

摘要

Preparation method of Aqueous Dispersions of copolymers and Drug, Frozen, soluble in water. Is an amphipathic Copolymer dispersed in water with a Molecular Weight of at least 1.000, consisting of a Hydrophobic Component, a Hydrophilic Component biodegradable and biodegradable or not, regular dispersion to a Physiological pH buffered or neutral; mixing the dispersion with an aqueous solution of a water soluble Drug and freeze the resulting dispersion. These preparations have pharmacological applications in sustained release formulations.
