title: [The diffusion and dissolution of metronidazole and doxepin in semisolid pharmaceutical forms through synthetic membranes].
abstract: The dissolution and diffussion methods through homogeneous synthetic membrane were studied in different semisolid topical formulations containing metronidazole and doxepin. The results suggest that the rate of release showed a first order kinetic for one of the formulations and the rate of release described by Higuchi for the others.
