Uniformity of dosage units <6.02> Perform the test accord- ing to the following method: it meets the requirement of the Content uniformity test. Disintegrate 1 tablet of Pioglitazone Hydrochloride Tablets with 10 mL of 0.1 mol/L hydrochloric acid TS, add 70 mL of methanol, shake vigorously for 10 minutes, then add methanol to make exactly 100 mL, and centrifuge. Take exactly V mL of the supernatant liquid, add a mixture of methanol and 0.1 mol/L hydrochloric acid TS (9:1) to make exactly V?mL so that each mL contains about 26 mg of pioglitazone hydrochloride (C 19 H 20 N 2 O 3 S.HCl), and use this solution as the sample solution. Separately, weigh accurately about 33 mg of Pioglitazone Hydrochloride RS (separately, determine the water <2.48> in the same manner as Pioglita- zone Hydrochloride), dissolve in 10 mL of 0.1 mol/L hydro- chloric acid TS, and add methanol to make exactly 100 mL. Pipet 4 mL of this solution, add a mixture of methanol and 0.1 mol/L hydrochloric acid TS (9:1) to make exactly 50 mL, and use this solution as the standard solution. Determine the absorbances, A T and A S , of the sample solution and stand- ard solution at 269 nm as directed under Ultraviolet-visible Spectrophotometry <2.24> using a mixture of methanol and 0.1 mol/L hydrochloric acid TS (9:1) as the blank. |
