Methods and related compositions for reduction of fat

Abstract

Compositions and methods useful in the reduction of localized fat deposits in patients in need thereof using pharmacologically active detergents are disclosed. The pharmacologically active detergent compositions can additionally include anti-inflammatory agents, analgesics, dispersion or anti-dispersion agents and pharmaceutically acceptable excipients. The pharmacologically active detergent compositions are useful for treating localized accumulations of fat including, for example, lower eyelid fat herniation, lipodystrophy and fat deposits associated with cellulite and do not require surgical procedures such as liposuction.
