PREPARATION, CHARACTERIZATION, AND OPTIMIZATION OF MICROEMULSION FOR TOPICAL DELIVERY OF ITRACONAZOLE

Preparation and Characterization of Cyanocobalamin (Vit B12) Microemulsion Properties and Structure for Topical and Transdermal Application

  Objective(s): The objective of this study was to design a topical microemulsion of Vit B12 and to study the correlation between internal structure and physicochemical properties of the microemulsions. Microemulsions are thermodynamically stable mixtures of water, oil, surfactants and usually cosurfactants with several advantages for topical and transdermal drug delivery. The formul...

Preparation and Evaluation of Aceclofenac Topical Microemulsion

A topical preparation containing aceclofenac was developed using an o/w microemulsion system. Isopropyl myristate was chosen as the oil phase as it showed a good solubilising capacity. Pseudo-ternary phase diagrams were used to obtain the concentration ranges of the oil, surfactant (Labrasol) and co-surfactant (plurol oleique) for microemulsion formation. Five different formulations were formul...

Formulation and Evaluation of Hydrogel-Thickened Microemulsion For Topical Delivery of Minoxidil

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...
