The dissolution kinetics of sulfamethoxazol, trimethoprim and oxytetracycline hydrochloride from multicomponent solid
1Department of Applied Pharmacy, University of Medicine, Lublin, Poland.
Abstract:
Release profiles and dissolution kinetics of active substance, viz. sulfamethoxazol (SMO), trimethoprim (TMP), and oxytetracycline hydrochloride (OTC) from capsulated multicomponent dispersions was studied in a flow-cell apparatus at 37 degrees C by using a dissolution medium of 0.1 mol/l HCl. The results revealed that the relative dissolution efficiency (DE) and dissolution profiles of one active ingredient were affected by the presence of the two others. Vitamin C added caused the decreased the dissolution rate constants (K) and DE--values of all the active substances studied.
