S. Nakhare et Sp. Vyas, PROLONGED RELEASE MULTIPLE EMULSION BASED SYSTEM BEARING RIFAMPICIN -IN-VITRO CHARACTERIZATION, Drug development and industrial pharmacy, 21(7), 1995, pp. 869-878
Multiple emulsions containing rifampicin were prepared and evaluated f
or in vitro characterisation. The effect of pH of internal and externa
l aqueous phase on in vitro release profile of rifampicin from multipl
e emulsions were studied. The partition coefficient of rifampicin betw
een internal aqueous phase (at variable pH) and liquid paraffin (oily
phase) was estimated and its effect on the release profile was elucida
ted.
