In this research, Camptothecin-loaded mixed micelles (CPT-MMs) were formulated by combining Soluplus®, a novel amphiphilic excipient, with D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS). The use of appropriate excipients is crucial in stabilizing micellar structures and improving drug…

Abstract Capsaicin (CAP) has been implicated as a gastroprotective agent in the treatment of peptic ulcers. However, its oral administration is hampered by its poor aqueous solubility and caustic effect at high administered doses. To address these limitations, we describe the development of gastric…
