Simple, accurate, rapid, economical spectroscopic methods namely Zero order have been developed and validated for estimation of Pentoxifylline in tablet dosage form using distilled water as a solvent according to ICH Guidelines Q2R1. Absorbance of each solution was measured at 271.8 nm for zero order spectrophotometry. Pentoxifylline show linearity over the range of 5-25 μg/ml for the developed method. Therefore, the proposed method can be applied for routine analysis of Pentoxifylline in tablet dosage forms.
