Preparation and evaluation of matrix type of transdermal patches containing anti –diabetic drug

The current research aims to formulate and evaluated medicated transdermal patches containing an anti-diabetic drug. A good penetration enhancer would improve drug delivery from various polymer-based transdermal patches. Transdermal patches of the matrix type are made. Using various PVP K30, MC ratios and solvent evaporation techniques. All prepared formulations were tested for weight variation, thickness, drug content, moisture content, moisture uptake, flatness, and in vitro drug release. Bath F3 was optimised formula from all formulation baths shows linear zero order release for 24 hours, with a cumulative percentage of drug diffusion of 87.35% from 4cm2 patches. It has been determined that polymer concentration. When the concentration of PVP K30 increases in the primary layer, the in – vitro diffusion rate increases, and when the concentration of PVP K30 decreases, the drug diffusion decreases. It allows for more controlled drug release from the patch.
