UV, first derivative, second derivative and AUC-spectrophotometric methods for the
determination of Frovatriptan Succinate Monohydrate (FSM) in pharmaceutical formulations
have been developed. For the first method, UV-spectrophotometry, standard solutions were
measured at 279 nm. The linearity ranges were found to be 1?¢?????80 ?Ž?¼gml?¢?????1 in 0.1N HCl and the
regression equation was A=1.8866?????10?¢?????2C-2.3397?????10?¢?????3 (r=0.9992). For the second method,
first derivative spectrophotometry, the response (dA/d?Ž?») of standard solutions was measured at
292 nm. Calibration curve was constructed by plotting dA/d?Ž?» values against concentrations, 2.5?¢?????
80 ?Ž?¼gml?¢?????1 of FSM standards in 0.1N HCl. Regression equation of linear calibration graph was
calculated as D1= -6.36?????10?¢?????4C-1.73?????10?¢?????4(r=0.9997). For the third method, second derivative
spectrophotometry, the response (d2A/d?Ž?»2) of standard solutions was measured at 281 nm.
Calibration curve was constructed by plotting d2A/d?Ž?»2 values against concentrations, 10?¢?????80 ?Ž?¼g
ml?¢?????1 of FSM standards in 0.1N HCl. Regression equation of linear calibration graph was
calculated as D2= -9.7?????10?¢?????5C ?¢????? 6.1?????10?¢?????5 (r=0.9995). The fourth method was based on
calculation of Area under Curve (AUC) for analysis of FSM in the wavelength range of 274?¢?????284
nm. Calibration curve was constructed by plotting AUC values against concentrations, 1?¢?????80 ?Ž?¼g
ml?¢?????1of FSM standards in 0.1N HCl. Regression equation of linear calibration graph was
calculated as AUC=0.1855C-0.0246 (r=0.9992). The methods were validated by following the
analytical performance parameters suggested by the International Conference on
Harmonization. All validation parameters were within the acceptable range. The developed
methods were successfully applied to estimate the amount of FSM in pharmaceutical
formulations.
