Visceral meshes, functionalised with an efficient drug carrier system – hydroxypropyl beta-cyclodextrin polymer (polyHPβCD) coating, were developed to give a prolonged intraperitoneal analgesic drug release. We attempted to evaluate the in vivo pain-relief efficacy of ropivacaine loaded polyHPβCD functionalised polyester meshes in a rat model of visceral pain induced by colorectal distension (CRD). In vivo safety, pharmacokinetic profile and biodegradation were measured via histological analysis and high-performance liquid chromatography, etc. The results confirmed that the polyHPβCD on the functionalised meshes has a high adsorption capacity of ropivacaine and resulted in a sustained drug release in rats after mesh implantation. This was further reaffirmed by an elevated pain threshold (30%) up to 4 days after implantation in the rat CRD model, compared to 1–2 days for non-adapted meshes. Neither polyHPβCD nor the loaded ropivacaine had a major impact on the inflammatory response. This evidence strongly suggests that polyHPβCD functionalised visceral mesh could be a promising approach for post-operative pain control by improving the intraperitoneal drug delivery and bioavailability.Show less >
