Rifampicin is a powerful bactericidal antitubercular drug. The drug was formulated as suppositories. Witepsol H12 was used as the formulating base. Certain other bases as witepsol H15 and W35 and Massa estarinum B and BC as well as cacao butter replaced witepsol H12. Non-ionic surfactants with different chemical compositions, different HLB values as well as different physical and solubility properties were incorporated into witepsol H12 at 5% concentration, of the tested surfactants were polysorbates. Spans, Myrjs and Brijs. Drug dialysis into saline solution at 37°C was studied through cellophane membrane, of the tested bases. Witepsols gave the highest dialysis rates. Polysorbates proved to be superior among the tested surfactants.
