Studies on Complex Formation in Aqueous Solution by Caffeine and Nicotinamide Interaction of Caffeine and Nicotinamide with Lidocaine and Saccharin

수용액중 Caffeine 또는 Nicotinamide 에 의한 Complex 형성에 대한 연구 Lidocaine 또는 Saccharin에 대한 Caffeine 또는 Nicotinamide의 상호작용

This investigation is the studies on the solubility analysis for several pharmaceuticals. The equilibrium reactions leading to complex formation of Caffeine and Nicotinamide with Lidocaine and Saccharin have been studied. The equilibrium constant of each complexes have also been calculated. It is shown that complex formation may lead to an increase in the solubilities of the reactants, and that Nicotinamide has more complexing activity than Caffeine. The influence of chemical structure of each components on interaction is also discussed.
