Zolmitriptan is used in the acute treatment of migraine attacks. It was quantified by reverse phase HPLC equipped with Sunniest (C18, 150 x 4.6 mm, 5.0 µ) column and mobile phase using pH 8.5 buffer and methanol as organic modifiers and flow rate is adjusted to 1.0 mL/min Column temperature is maintained at 40˚C. Injection volume is 10µL. the retention time was found to be 5.7 min. The standard plots were constructed between concentrations vs. peak area a linear response of peak area was observed over the concentration range of 125-750 µg/mL for Zolmitriptan The regression equations of concentration Zolmitriptan was found to be y = 324.47x + 3.400, where y is the peak area and x is the concentrations of drugs (μg/mL).
Key words: Zolmitriptan, RP-HPLC, Estimation and validation
