Tamoxifen in topical liposomes: development, characterization and in-vitro evaluation.

Abstract

Tamoxifen molecules could be successfully entrapped in the liposomes with reasonable drug-loading and desired vesicle specific characters. Higher rate of drug transfer across the skin with liposomal formulations of tamoxifen, suggests that the drug in its lipo-solubilised state might have found facilitated entry into the tough barrier consisting of stratum corneum. The phospholipid enriched amphiphillic nature of the vesicles can be held responsible for modifying the properties of the keratinised layer. Integration of phospholipid molecules with the skin lipids might have served further, to help retain the drug molecules within the skin, thus leading to prolonged presence of drug molecules at the receptor site. These findings have been seen to support the improved and localized drug action in the skin, thus providing a better option to deal with skin-cited problems.
