Title:Echinocandin pharmaceutical formulations containing micelle-forming surfactants
Abstract:Pharmaceutical formulations are described comprising an echinocandin compound or echinocandin/carbohydrate complex and a pharmaceutically acceptable micelle-forming surfactant in a non-toxic aqueous solvent such that the solubilization of the echinocandin compound is optimized and the ability to freeze-dry the solution is maintained. Both the solution and freeze-dried formulations have increased stability. A bulking agent, tonicity agent buffer and/or a stabilizing agent may optionally be added to the formulations to further enhance the stability of the formulation.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
