Abstract
This investigation assessed 32 formulations of liquid self-microemulsifying drug delivery system (L-SMEDDS) for pioglitazone (PGZ). The optimal PLS12 formulation comprises 40% capmul MC8 (oil), 40% cremophore RH40 (surfactant), and 20% PEG (co-surfactant). PLS12 exhibited approximately 75 nm droplet size, below 200 nm, and a PDI of 0.47, indicating nanosized droplets with uniform distribution. The formulation demonstrated stability, and achieved supreme drug loading capacity. The enhanced L-SMEDDS was solidified into solidified SMEDDS utilizing Sylloid 244 FP, subsequently in a free-flowing powder without drug interactions. Tablets were successfully formulated by incorporating S-SMEDDS with diverse tableting excipients. The selected tablet batch passed quality control and stability tests. The tablet exhibited a rapid and pH-independent release profile. The combined impact of SMEDDS and tablets collectively enhanced the solubility and dissolution of PGZ hydrochloride
