- Surgical suture assembled with a drug-delivery polymer strand is proposed.
- Drug is released from the suture in a sustained manner.
- The mechanical strength needed for wound closure is retained.
- Drug-delivery suture can mitigate the pain in pain-induced animal models.
In this work, we propose a surgical suture that can sustainably release diclofenac (DF) for the local pain relief of surgical wounds. We separately fabricated a DF-loaded strand composed of a biodegradable polymer, poly(lactic-co-glycolic acid) (PLGA), which was then braided with a surgical suture already in clinical use, i.e., VICRYLâ¢. In this way, the drug-delivery suture presented herein could release DF in a sustained manner for 10 days while maintaining the mechanical strength needed for wound closure. According to the in vivo results of an induced-pain animal model, the drug-delivery suture mitigated pain throughout the period of persistent pain. The histological analysis of tissue around the sutures showed that the drug-delivery suture exhibited biocompatibility comparable to that of the VICRYL⢠suture in clinical use.
