Poly(D,L-lactide) (PDLLA) is widely used in the medical and pharmaceutical industries due to its biodegradability and biocompatibility. It is commonly employed in the development of drug delivery systems, where it serves as a carrier for controlled release of medications, ensuring sustained therapeutic effects. PDLLA is also utilized in the fabrication of surgical sutures, implants, and scaffolds for tissue engineering, as it gradually degrades in the body without causing adverse reactions. Additionally, it finds applications in orthopedic devices, such as pins and screws, which provide temporary support during bone healing. Furthermore, PDLLA is used in cosmetic procedures as a dermal filler to stimulate collagen production, helping to reduce wrinkles and enhance skin rejuvenation. Its versatility and safety make it a valuable material in advancing medical technologies.
