Abstract

See full text

The present invention relates to improvements in compositions containing peptides that are ligands of one or more of the melanocortin receptors (MC-R), or pharmaceutically acceptable salts thereof, methods for preparing such compositions, and method of using such compositions to treat mammals. In particular, the present invention relates to a pharmaceutical composition comprising a pamoate salt of Ac-Arg-cyclo(Cys-D-Ala-His-D-Phe-Arg-Trp-Cys)-NH2 which is a ligand of the melanocortin receptor subtype 4 (MC4-R), and in which, after subcutaneous or intramuscular administration to a subject, the peptide forms a depot at physiological pH that is slowly dissolved and released into the body fluid and bloodstream. The present invention may further comprise an organic component such as dimethylacetamide (DMA) or polyethylene glycol (PEG) with an average molecular weight of lower than 1000.
