Injection system for the application of semi-solid, depot-shaped pharmaceutical compositions of gellable peptide salts

摘要

The invention features a solid, non-particulate, sustained-release pharmaceutical composition for parenteral administration to a patient. The composition consists essentially of (1) a soluble, gelable peptide salt, and (2) up to 30 percent, by weight, of a pharmaceutically acceptable, monomeric, soluble carrier, compounded into a solid cylindrical form, wherein the solid composition automatically forms a gel after interaction with the patient's bodily fluids, the gel releasing the peptide continuously within the patient over an extended period of at least three days.
