Abstract
The interactions between drugs (Fluoxetine hydrochloride, cyproheptadine hydrochloride and Metformin hydrochloride) and additives were studied by conductometric technique. Increase in conductance is observed as the percentage of ethanol decreases in ethanol-water mixture. However, when the additives NaCl, KCl, CuCl2, NiCl2 and glucose, are added, the magnitude of conductance differs for different additives. The Walden product decreases with increase in percentage of ethanol in mixture. The Walden product in presence of NaCl and KCl is observed to be less than the Walden product in presence of NiCl2 and CuCl2.
