5.0 PROCEDURE
5.1 Label Claim:
Each film coated tablet Contains:
Febuxostat IP ……………….40/80mg
5.2 Assay Method:
5.2.1 Preparation of standard solution:
Dissolve 50mg of the Febuxostat in 25ml of methanol water and
further diluted to 50ml with methanol. Further dilute 1ml of the above solution
into 100ml with methanol.
5.2.2 Preparation of Sample solution:
Weight powder twenty tablets and take the powder equivalent to 50mg in methanol
was accurately weighed, dissolved in 25ml of methanol, filtered through
Whatmann filter paper No: 41 further diluted to 50ml with methanol.
Further dilute 1ml of the above solution into 100ml with methanol
5.2.3 Measure the absorbance at about 315nm
5.2.4 Calculate the content by
comparison.
Sample absorbance x Standard weight x Assay x
Average weight of the tablet =
Standard absorbance x Sample Weight x
