Furosemide Tablets

Action and use

Loop diuretic.


Furosemide Tablets contain Furosemide.

The tablets comply with the requirements stated under Tablets and with the following requirements.

Content of furosemide, C12H11ClN2O5S

95.0  to 105.0% of the stated amount.

A.  The light absorption, Appendix II B, in the range 220  to 320  nm of the final solution obtained in the Assay exhibits two maxima, at 228  nm and 271  nm.

B.  In the test for Related substances, the principal peak in the chromatogram obtained with solution (2) shows a peak with the same retention time as the principal peak in the chromatogram obtained with solution (3).



Tablets containing less than 100  mg of Furosemide comply with the requirements for Monographs of the British Pharmacopoeia in the dissolution test for tablets and capsules, Appendix XII B1, using Apparatus 2. Use as the medium 900  ml of phosphate buffer pH 5.8 and rotate the paddle at 50 revolutions per minute. Withdraw a sample of 10  ml of the medium, filter and dilute the filtrate with sufficient of the dissolution medium to give a solution expected to contain about 0.001% w/v of Furosemide. Measure the absorbance of this solution, Appendix II B, at 277  nm using dissolution medium in the reference cell. Calculate the total content of furosemide, C12H11ClN2O5S, in the medium from the absorbance obtained from a 0.001% w/v solution of furosemide BPCRS in the dissolution medium and using the declared content of C12H11ClN2O5S in furosemide BPCRS.

Related substances

Carry out the method for liquid chromatography, Appendix III D, using the following solutions. Prepare the solutions immediately before use and protect from light. For solution (1) dissolve a quantity of the powdered tablets containing 20  mg of Furosemide in sufficient of the mobile phase to produce 50  ml and mix with the aid of ultrasound for 15  minutes. For solution (2) dilute 1  volume of solution (1) to 500  volumes with the mobile phase. Solution (3) contains 0.00008% w/v of furosemide BPCRS in the mobile phase. Solution (4) contains 0.00008% w/v of each of furosemide BPCRS and furosemide impurity A EPCRS in the mobile phase. Solution (5) contains 0.00032% w/v of 4-chloro-5-sulphamoylanthranilic acid BPCRS in the mobile phase.

The chromatographic procedure may be carried out using (a) a stainless steel column (25  cm × 4.6  mm) packed with octylsilyl silica gel for chromatography (5 µm) (ChromSpher C8 is suitable), (b) as the mobile phase with a flow rate of 1  ml per minute a mixture prepared in the following manner: dissolve 0.2  g of potassium dihydrogen orthophosphate and 0.25  g of cetrimide in 70  ml of water, adjust the pH to 7.0 with 6m ammonia and add 30  ml of propan-1-ol and (c) a detection wavelength of 238  nm.

Inject 100 µl of solution (4). Adjust the sensitivity of the system so that the heights of the two peaks in the chromatogram obtained are not less than 20% of the full-scale of the recorder. The test is not valid unless the resolution factor between the first peak (furosemide impurity A) and the second peak (furosemide) is at least 4.

Inject 100 µl of solution (1) and allow the chromatography to proceed for three times the retention time of the principal peak. In the chromatogram obtained with solution (1) the area of any peak corresponding to 4-chloro-5-sulphamoylanthranilic acid is not greater than the area of the peak in the chromatogram obtained with solution (5) (0.8%) and the sum of the areas of any other secondary peaks is not greater than 2.5  times the area of the first peak in the chromatogram obtained with solution (4) (0.5%). Disregard any peak with an area less than 0.1  times the area of the first peak in the chromatogram obtained with solution (4) (0.02%).


Weigh and powder 20  tablets. Shake a quantity of the powder containing 0.2  g of Furosemide with 300  ml of 0.1m sodium hydroxide for 10  minutes, add sufficient 0.1m sodium hydroxide to produce 500  ml and filter. Dilute 5  ml to 250  ml with 0.1m sodium hydroxide and measure the absorbance of the resulting solution at the maximum at 271  nm, Appendix II B. Calculate the content of C12H11ClN2O5S taking 580 as the value of A(1%, 1  cm) at the maximum at 271  nm.
