Purpose The present study aims to overcome the poor oral bioavailability of ezetimibe (EZ), a selective Biopharmaceutics Classification System (BCS) Class II cholesterol absorption inhibitor drug. EZ-loaded nanostructured lipid carriers (EZ-NLCs) were dried by lyophilization and incorporated in a convenient oral solid dosage form to enhance its dissolution, and absorption and increase patient compliance. Response surface metho...

Purpose Up-to-date literature offers limited data about utilizing atorvastatin calcium (ATV) as a promising chondroprotective agent in osteoarthritis (OA). So, this study aims to develop a depot intra-articular (IA) delivery system for ATV to enhance its deposition in the articular joint. Methods A 3 3 D-optimal design was implemented to prepare ATV-loaded lecithin-coated zein nanoparticles. The optimized formulation (Opt-LCZN...

Dysregulation of protein homeostasis, proteostasis, is a distinctive hallmark of many neurodegenerative disorders and aging. Deleteriously, the accumulation of aberrant proteins in Alzheimer’s disease (AD) is accompanied with a marked collapse in proteostasis network. The current study explored the potential therapeutic effect of vardenafil (VAR), a phosphodiesterase-5 inhibitor, in AlCl 3 / d -galactose ( d -gal)-induced AD i...
