The present invention relates to vesicular formulations containing a prodrug, characterized for comprising the combination of a prodrug of weak organic acids having the following general formula: R 1 COOH (I) or R 1 SO 2 H (II) wherein R 1 is preferably selected from the group containing a benzenic, pyridinic, pyrazinic or pyrimidinic aromatic ring, or a linear chain substituted or unsubstituted, saturated or unsaturated, such as benzoic, benzenesulphinic, cinnamic, salicylic, pyrazinoic, nicotinic, carboxylic pyridazine and carboxylic pyrimidine, caproic, caprylic, capric, lauric, myristic, palmitic and estearic acids; with a liposomal or micellar carrier, which protects the prodrug from plasma degradation. The invention further relates to the process of preparation of liposomal formulations, novel prodrugs and pharmaceutical compositions intended for use in the treatment of tuberculosis and other mycobacterioses. |
