Disclosed herein are compositions for the delayed delivery of peptide active agents, including compositions comprising; i) a salt of a peptide active agent comprising at least one positively charged peptide ion and at least one negatively charged counter-ion selected from a halide ion, a chloride and a bromide ion; and ii) a sustained-release delivery vehicle.


Patent
Camurus Ab | Date: 2013-09-04

The present invention relates to pre-formulations comprising low viscosity, non-liquid crystalline, mixtures of: a) at least one neutral diacyl lipid and/or at least one tocopherol; b) at least one phospholipid;c) at least one biocompatible, oxygen containing, low viscosity organic solvent;wherein at least one bioactive agent is dissolved or dispersed in the low viscosity mixture and wherein the pre-formulation forms, or is capable of forming, at least one liquid crystalline phase structure upon contact with an aqueous fluid. The preformulations are suitable for generating parenteral, non-parenteral and topical depot compositions for sustained release of active agents. The invention additionally relates to a method of delivery of an active agent comprising administration of a preformulation of the invention, a method of treatment comprising administration of a preformulation of the invention and the use of a preformulation of the invention in a method for the manufacture of a medicament.


Patent
