Novel Salts of Sunitinib an Anticancer Drug with Improved Solubility

Sangeeta Sangwan, Tapas Panda, Ram Thiamattam, Sharwan K. Dewan & Rajesh K. Thaper · International Research Journal of Pure and Applied Chemistry · 2014

Polymorph, co-crystal and salt screening experiments were carried out to identify novel solid forms with the improved physicochemical properties, particularly water solubility in the present case. Co-crystal formation was evaluated with urea and nicotinamide. These coformers do n...
