A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.

Described in this manuscript is the first reported new, simple high performance thin layer chromatographic method for the determination of tapentadol hydrochloride in bulk and its tablet dosage form. The drug was separated on aluminum plates precoated with silica gel 60 F254 with butanol: water: glacial acetic acid in the ratio of 6:2:2 (v/v/v) as mobile phase. Quantitative analysis was performed by densitometric scanning at 254 nm. The method was validated for linearity, accuracy, precision and robustness. The calibration plot was linear over the range of 200-600 ng band -1 for tapentadol hydrochloride. The method was successfully applied to the analysis of drug in a pharmaceutical dosage form.
