ABSTRACT
Background: The aim of the study was to develop piroxicam-Aloe vera gel (PAG) formulation and make a pharmacodynamic evaluation of the formulation.Materials and Methods: The gel was prepared by using carbopol 934 as gelling agent and methyl paraben as a preservative in an Aloe vera gel base. The formulated gel was also evaluated for physicochemical parameters like pH, viscosity, drug content, and in vitro diffusion assessment. Pharmacodynamic activity of the formulation was evaluated in Wistar albino rats. The formulated gel was compared with that of similar marketed gel (commercial piroxicam gel (CPG)) against the same parameters.Results: From in vitro studies, an effective drug release from PAG was observed to be 68.17% when compared with that of the CPG (62.71%) at 180 min indicating better drug release from the gel formulated in this study. Percentage inhibition of edema was greater for the preparation of PAG (29.57 mean percent inhibition after 60 min) compared to marketed gel which exhibited 18.3% after 60 min.Conclusion: It was concluded from the results that the Aloe vera gel acts as an effective gel base to prepare piroxicam gel with high drug loading capacity and improved anti-inflammatory effect. From the statistical analysis the formulation of PAG showed better release than the CPG at p < 0.05 level of significance.
