Formulation and evaluation of Ketorolac tromethamine for transdermal drug delivery system

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as Ketorolac Tromethamine are widely recommended to treat pain caused by osteoarthritis, ankylosing spondylitis, acute sciatica, rheumatoid arthritis and low back pain. Modern drug delivery technology, such as transdermal patches, is mostly used in the treatment of numerous diseases. As first-pass metabolism is avoided. Transdermal drug delivery systems (TDDS) can efficiently enhance bioavailability and help with the planned and controlled release of drug molecules into the systemic circulation. The purpose of this work was to produce matrix-type Ketorolac tromethamine transdermal patches by solvent evaporation using different polymer ratios, such as HPMC 15 cps, HPMC E5, and Eudragit S 100. Along with solvents like methanol and chloroform, plasticizers like glycerine, propylene glycol, and PEG 200 are used in this formulation. According to the FTIR study, Ketorolac Tromethamine had no significant interactions with other excipients. The following evaluations are carried out such as thickness, weight variation, folding durability, moisture content, drug content, surface pH, and In vitro diffusion are all evaluated for the prepared patches.
