Formulation and In-vitro Evaluation of Tretinoin Microemulsion as a Potential Carrier for Dermal Drug Delivery
Authors
Abstract:
In this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. The effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. In released studies, static Franz diffusion cells mounted with dialysis membrane were used. Sampling was conducted every 3 h at room temperature over a period of 24 h. The amount of released drug was measured with UV-spectrophotometer and the percentage of drug released was calculated. Based on the results obtained, the oil phase concentration had a proportional effect on particle size which can consequently influence on drug release. The particle size and the amount of released drug were affected by the applied surfactants. The components of the optimized microemulsion formulation were 15% olive oil, 12% propylene glycol (as co-surfactant), 33% Tween®80 (as surfactant) and 40% distilled water, which was tested for viscosity and rheological behavior. The prepared tretinoin microemulsion showed pseudoplastic-thixotropic behavior. The profile of drug release follows zero order kinetics. The optimized tretinoin microemulsion showed enhanced in-vitro release profile compared to the commercial gels and creams.

Background and purpose: Tadalafil has gained wide clinical acceptance in treatment of erectile dysfunction due to its long treatment window and lower potential for visual impairment. Transdermal drug delivery prevents systemic elimination, drug-drug and food-drug interactions, and reduces side effects by reducing the dose of the drug. The aim of this study was to evaluate the effect of microemu...

The available minoxidil formulations for topical application suffer with major drawback and requires repeated application. The present study was aimed to investigate the effect of microemulsions and microemulsion based hydrogel-systems (MEHs) for increased percutaneous penetration of minoxidil. Minoxidil microemulsions were developed by conventional titration method using oleic-acid as oil, twe...
