Co-crystal screening of poorly water-soluble active pharmaceutical ingredients. Application of hot stage microscopy on curcumin-nicotinamide system and construction of ternary phase diagram of fenbufen-nicotinamide-water co-crystal system.
Curcumin is the major phenolic diarylheptane derivative in Curcuma longa and has been reported to possess pharmacological activities. Unfortunately this compound suffers from poor bioavailability and rapid neutral-alkaline degradation. Co-crystal of curcumin is one option under exploration, …
