Chemical relaxation in mixed micellar solutions containing surface-active drugs and hexadecyltrimethylammonium bromide micelles

Abstract

A study of chemical relaxation in mixed micellar solutions containing surface-active drugs and hexadecyltrimethylammonium bromide micelles is reported. The incorporation of drug molecules into the micelles takes place at a rate which appears to be diffusion controlled and the rate coefficient for the release of drug increases with the proportion of drug within the micelle. The ionic nature of the drugs appears to have little effect on the kinetic behaviour.
