Particle formation pathways and polymorphism of curcumin induced by ultrasound and additives during liquid antisolvent precipitation

Precipitation of curcumin, a poorly water-soluble drug, has been carried out by the liquid antisolvent technique in the presence of ultrasound and stabilizers. Curcumin particles with varied morphology were observed to have formed during precipitation in the presence of ultrasound and additives such as sodium dodecyl sulfate (SDS), Tween 80, hydroxyl propyl methylcellulose (HPMC), polyvinyl pyrrolidone (PVP), and bovine serum albumin (BSA)....
