RESUMO
The aim of the present study was to design and evaluate the suppositories of aceclofenac a non-steroidal anti inflammatory drug (NSAID). Aceclofenac, rectal suppositories were developed by employing various hydrophilic and hydrophobic polymeric bases like gelatin, PEG-400 and hydrogenated vegetable oil using propylene glycol as plasticizer and beeswax as hardening agent. The in-vitro release rate data was evaluated statistically and was found that from all the formulations the drug release is by diffusion mechanism (r = 0.9547 to 0.9967) according to Higuchi’s equation. All the prepared formulations have shown zero-order release kinetics except those prepared by utilizing 15% and 20 % of PEG-400. The formulation prepared using 7.5% beeswax in hydrogenated vegetable oil has dis-played zero-order drug release (r = 0.9927) and has released 99.18% of the aceclofenac within 4h, hence, this formulation is considered as a promising formulation. The stability study on the promising formulation was con-ducted over a period of 6 months and found that there are no significant changes in the drug content and in-vitro drug release rate (p<0.05). The result suggests that the suppositories can be prepared by employing hydrophilic and hydrophobic polymers.
