FORMULATION AND EVALUATION OF ACECLOFENAC PRONIOSOME LOADED ORABASE FOR MANAGEMENT OF DENTAL PAIN

Objective: The main motive is to develop proniosomes loaded orabase for enhanced permeation and prolonged release of aceclofenac for oro dental conditions. Methods: Various aceclofenac (ACL) proniosomal gels were formulated employing various surfactants, span 60 was superior and significant for loading into orabase. The formulations were scrutinized for entrapment efficiency, optical microscopy, in vitro diffusion and release studies, mucoadhesive strength, ex-vivo permeation studies and drug-excipient interactions were determined by FTIR spectroscopy. Results: Considering best entrapment efficiency with span 60 (97.60±1.85) and optimum vesicle shape, along with prolonged drug permeation (45% for 24 h) the formulation F(ACL)1 was selected and optimized for loading into orabase. The F(ACL)1 loaded orabase exhibited significant prolonged release over 14 h, and permeation profiles exhibited nearly two-fold increased flux in comparison with control. Good mucoadhesive strength was observed for proniosomal orabase 6370 dynes/cm 2 . No evidence of incompatibility amongst formulation components from FTIR studies. SEM images revealed the particle size range from 136 µm to 236 µm for proniosomal orabase. Conclusion: Orabase can be an effective carrier for proniosomes with enhanced permeation and prolonged release for oro-dental conditions.
