Poly(lactic acid) PLA (PLA) is a versatile biocompatible polymer widely used in drug delivery systems. However, its rapid degradation and poor water solubility limit its efficacy. To overcome these challenges, PEGylation, the process of attaching polyethylene glycol PEG chains, has emerged as a promising strategy. Biocompatible PEGylation enhances PLA's dissolvability, promoting sustained drug release and reducingpremature elimination. This controlled drug delivery approach offers numerous benefits, including improved treatment outcomes and reduced side effects.
The biocompatibility of PEGylated PLA stems from its non-toxic nature and ability to evade the immune system. Furthermore, the hydrophilic nature of PEG improves the drug's solubility and bioavailability, leading to stable drug concentrations in the bloodstream. This sustained release profile allows for less frequent treatments, enhancing patient compliance and minimizing irritation.
