Development of a liposome formulation of ethambutol.

A liposomal formulation capable of encapsulating 76 to 92% of the antimycobacterial drug ethambutol and showing prolonged in vitro release kinetics is described. In vitro efficacy is equivalent to that of the free drug, suggesting that encapsulation of ethambutol has the potential to shorten the current regimens for tuberculosis.

Pharmacokinetic comparison of intravenous carbendazim and remote loaded carbendazim liposomes in nude mice.

Carbendazim is a novel anticancer agent. The aim of this study was to prepare and characterize a remote loaded liposome preparation of carbendazim, and compare its pharmacokinetic profile to that of unencapsulated carbendazim. Carbendazim was encapsulated in liposomes composed of sphingomyelin-cholesterol (3:1, w/w) by remote loading in response to a transmembrane pH gradient (pH 0.
