Asimple, precise, accurate and rapid High Performance Thin Layer Chromatography (HPTLC) method was developed for the simultaneous estimation of Diclofenac Potassium and Tizanidine Hydrochloride in tablet dosage forms. A CAMAG Linomat IV Sample Applicator in Precoated silica gel Plate 60F 254 (Merck) and the mobile phase solvent system consisting of Toluene: Isopropyl alcohol:Ammonia (30:20:2.5)were used.The drugswere scanned for Rf values in the scanner at the wave length 280nm. The Rf value of Diclofenac Potassiumand Tizanidine were 0.62 - 0.69 and 0.85-0.92 respectively. The Linearity forDiclofenac PotassiumandTizanidineHCLwere in the range of 3000 to 7000 g/ml and 120 to 260 g/ml.Results of the analytical method were validated statically, and by recovery studies. The Proposed method can be successfully used to determine the drug contents ofmarketed formulation.
