Plga water solubility
Webb1 dec. 2024 · Cannabidiol (CBD) has emerged as a potential therapeutic agent. However, its low aqueous solubility hinders the development of effective parenteral formulations. The use of polymeric microparticles as CBD carriers could resolve this challenge and allows to obtain an extended CBD release after a single administration. Poly(lactic-co-glycolic … WebbThe water solubility of CUR in NCs increased about 1500 fold compared to that of free CUR. TEM and AFM images proved the core–shell structure of PLGA NCs with narrow size distributions. The in vitro release profile of CUR from PLGA NCs showed a burst release in the initial 24 h followed by a sustained release of the interior CUR over 10 days.
