FORMULATION STRATEGIES IN STABILIZING PEPTIDES IN ORGANIC SOLVENTS AND IN DRIED STATES

The invention relates to stabilized formulations of therapeutically active peptides, particularly PACAP 66. Formulations of the invention include a peptide containing at least one histidine residue, a transition metal salt and an organic solvent. The above formulations may contain peptides that have at least one asparagine residue and are acidified and dried (such as spray-dried or freeze-dried) before formulation preparation. Other formulations of the invention relate to stabilized formulations of PACAP 66 or peptides containing an asparagine residue, which are acidified and dried (such as spray-died or freeze-dried) with or without a transition metal salt.
