Formulation and Evaluation of Olmesartan Medoxomil Transdermal Drug Delivery System

Abstract

Transdermal patches are cutting-edge drug delivery methods that are essential to the management of many diseases. Due to the avoidance of first pass metabolism the drug molecules are delivered into the systemic circulation at a controlled and predefined pace with the help of TDDS, which also helps to achieve efficient bioavailability. This study's goal was to create matrix-type Olmesartan medoxomil transdermal patches utilizing the solvent evaporation method and various polymer ratios, including HPMC 15 cps, HPMC 5 cps, and Eudragit S 100. Plasticizers like glycerin, propylene glycol, and PEG 200 are used, along with solvents like methanol and chloroform. According to FT-IR studies, pure drugs and excipients are compatible with each other. The generated patches are assessed for their thickness, weight variation, folding endurance, moisture content, drug content, surface pH, and in vitro diffusion studies. Among all the formulations, F6 showed the best characteristic properties and in vitro drug diffusion.
