摘要
Rizatriptan benzoate is a 5HT 1B/1Dreceptor agonist which is prescribed for the treatment of migraine.In the present study new,simple,specific ultraviolet spectrophotometric method for rizatriptan benzoate was developed and validated.Forced degradation studies were carried out in acidic,alkaline and neutral pH conditions.The absorbance maxima peak was found to be 224 nm and linearity was observed in the concentration range of 0.5~2.5μg·mL-1 with regression coefficient value of 0.998 8.The method was validated and found to be precise.The percent recovery for rizatriptan benzoate was found to be 98.576±0.202.The bulk drug was found to be stable in neutral and acidic pH conditions but got degraded in 1N NaOH solution.
