|Title:||Nefopam hydrochloride loaded microspheres for post-operative pain management: synthesis, physicochemical characterization and in-vivo evaluation|
|Publisher:||Taylor and Francis Ltd.|
|Abstract:||Once-daily oral dosage of nefopam hydrochloride loaded sustained release microspheres (NPH-MS) was investigated as novel therapeutic strategy for post-operative pain management. Microspheres were synthesized using poly-3-hydroxybutyrate and poly-(?-caprolactone) by double emulsion solvent evaporation technique. NPH-MS were characterized through FTIR, PXRD and SEM. In-vitro drug release study revealed sustained behavior till 24 h. Haemolysis was <5% which signified haemocompatibility of formulation. ED50 in rat tail-flick anti-nociceptive test was found ?18.12 mg/kg. In post-operative pain model, reversal of mechanical allodynia and thermal hyperalgesia by NPH-MS was statistically significant (p <.001) as compared with NPH till 24 h post-dose. � 2017 Informa UK Limited, trading as Taylor & Francis Group.|
