Glass Transition Temperature and Drug Release from PLGA-Based Microspheres
Poly(lactic-co-glycolic acid) (PLGA) is a widely used polymer in drug delivery systems, particularly for creating long-acting injectable microspheres. A crucial factor influencing the drug release profile of these formulations is the glass transition temperature (Tg), which represents the temperature at which PLGA transitions from a hard, glassy state to a softer, rubbery state. Impact of…
