Formulation and Characterization of Aceclofenac -Aloe vera Transemulgel

Abstract

The present research was aimed to formulate aceclofenac transemulgel using Aloe vera as gel base. The prepared formulations were subjected to physical characterization, in-vitro and in-vivo assessment. Aceclofenac, a hydrophobic potential non steroidal anti inflammatory drug, causes ulceration upon chronic oral administration, could be formulated into transemulgel to enhance therapeutic efficacy and to lower the unwanted side effects. The transemulgel was prepared from aqueous Aloe vera gel and aceclofenac emulsion. The prepared transemulgel was evaluated for its pH, viscosity, drug content, skin irritation, in-vitro diffusion and accelerated stability studies. The prepared aceclofenac-Aloe vera tranemulgel and commercial aceclofenac gel were subjected to pharmacodynamic studies in albino rats of Wistar strain employing carrageenan induced left hind paw edema method to assess the anti-inflammatory effect. The transemulgel showed a pH of 6.78 and viscosity of 18 cps. In-vitro diffusion data revealed better permeation characteristics. Topical application of formulation found no skin irritation. Stability study has proved the integrity of the formulation. The prepared aceclofenac Aloe vera transemulgel showed better in-vitro drug release when compared with the commercial aceclofenac gel formulation. Anti-inflammatory activity in treated rats showed the significant paw volume reduction at p<0.05 compared with that of control. Thus, it is concluded that aceclofenac, a potential non steroidal anti inflammatory drug, showed high therapeutic efficiency when formulated into transemulgel using aqueous Aloe vera as gel base.

In vitro assessment of non-irritant microemulsified voriconazole hydrogel system

“…The selected MBH system was carefully applied on depilated portion of the animal skin. The treated rats were observed for the changes on their skin surface for a period of 36 h (Prasanna Raju et al 2015).…”
