Antibiotic formulation and use for drug resistant infections

A liposomal aminoglycoside formulation comprising a neutral lipid, a negatively charged lipids and a sterol. The formulation contains unilamellar vesicles having an average size below 100 nm. A process of making liposomes containing an aminoglycoside is provided where the hydration temperature is significantly below the transition temperature of the formulation. A method for the treatment of drug susceptible and drug resistant bacteria.

A thin-film evaporator for preparing liposomes in commercial quantities provides a film-forming zone of uniform thickness which enables the uniform evaporation of an organic solvent to form a film of uniform thickness, followed by in situ hydration of the film in an aqueous phase by agitation with a rotor.

Film-forming evaporation apparatus

A single-vessel method is provided for preparing liposomes in commercial quantities by forming a homogeneous and uniform lipid film in a thin-film evaporator by evaporation of the organic solvent, followed by in situ hydration of the film in an aqueous phase by agitation with the rotor.
