Sulindac Tablets 

Action and use

Cyclo-oxygenase inhibitor; analgesic; anti-inflammatory.


Sulindac Tablets contain Sulindac.

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

Content of sulindac, C20H17FO3S

95.0  to 105.0% of the stated amount.

A.  Shake a quantity of the powdered tablets containing 0.1  g of Sulindac with 10  ml of a mixture of equal volumes of chloroform and methanol for 10  minutes, filter and evaporate the filtrate to dryness. The infrared absorption spectrum of the residue, Appendix II A, is concordant with the reference spectrum of sulindac (RS 323).

B.  The light absorption, Appendix II B, in the range 230  to 350  nm of the solution obtained in the Assay exhibits two maxima, at 284  nm and 327  nm, and a less well-defined maximum at 258  nm.


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 7.2 and rotate the paddle at 50 revolutions per minute. Withdraw a sample of 10  ml of the medium, filter and dilute with phosphate buffer pH 7.2 to give a solution expected to contain 0.001% w/v of Sulindac. Measure the absorbance of this solution, Appendix II B, at 327  nm using phosphate buffer pH 7.2 in the reference cell. Calculate the total content of C20H17FO3S in the medium taking 373 as the value of A(1%, 1  cm) at the maximum at 327  nm.

Carry out the method for liquid chromatography, Appendix III D, using the following solutions. Mix 160  volumes of tetrahydrofuran and 840  volumes of methanol (solution A). Mix equal volumes of solution A and a solution containing 0.358% w/v of disodium hydrogen orthophosphate and 0.34% w/v of tetrabutylammonium hydrogen sulphate (the mixture is solution B). For solution (1) shake a quantity of whole tablets containing 1  g of Sulindac with 175  ml of solution A mechanically for 15  minutes and then with the aid of ultrasound until the tablets have fully disintegrated (at least 15  minutes). Allow the resulting suspension to cool, add sufficient of solution B to produce 200  ml and mix. Dilute 10  ml of the resulting solution to 100  ml with solution B and filter through a 0.45-µm filter (Millipore Millex is suitable). For solution (2) dilute 1  volume of solution (1) to 100  volumes with solution B and further dilute 1  volume to 2  volumes with the same mixture of solvents. Solution (3) contains 0.050% w/v of sulindac EPCRS (which has an assigned content of the E-isomer) in solution B. For solution (4) add 0.05  ml of a 3% w/v solution of potassium permanganate to 5  ml of solution (1) (generation of sulphoxide impurity). For solution (5) add a few granules of zinc, in fine powder to 5  ml of solution (1), add 0.2  ml of hydrochloric acid, mix and filter through a 0.45-µm filter (generation of desoxy impurity). For solution (6) add 0.3  ml of methanol to 5  ml of solution (1), add 0.2  ml of sulphuric acid and mix (generation of methyl ester). For solution (7) add 0.3  ml of absolute ethanol to 5  ml of solution (1), add 0.2  ml of sulphuric acid and mix (generation of ethyl ester).

The chromatographic procedure may be carried out using (a) a stainless steel column (15  cm × 4.6  mm) packed with octylsilyl silica gel for chromatography (5 µm) (Beckman Ultrasphere C8 is suitable), (b) as mobile phases A and B with a flow rate of 2  ml per minute the solutions described below and (c) a detection wavelength of 330  nm. Carry out a linear gradient elution using the following conditions.

Mobile phase A  Mix 160  volumes of tetrahydrofuran and 840  volumes of methanol (solution C). Prepare a solution containing 0.358% w/v of disodium hydrogen orthophosphate and 0.34% w/v of tetrabutylammonium hydrogen sulphate and mix 380  volumes of solution C with 620  volumes of this solution, adjust the pH of the mixture to 6.0 with orthophosphoric acid or a 50% w/v solution of sodium hydroxide, mix with the aid of ultrasound for 10  minutes and filter through a 0.45-µm filter.

Mobile phase B  Acetonitrile.


Inject 20 µl of solution (3) and continue the chromatography for twice the retention time of the principal peak. The chromatogram obtained shows a principal peak corresponding to sulindac and a peak corresponding to the E-isomer with a retention time relative to sulindac of about 1.25.

From the chromatograms obtained with solution (1) and solution (3) calculate the content of E-isomer in the preparation being examined using the declared content of the E-isomer in sulindac EPCRS; the E-isomer content is not more than 0.5%. In the chromatogram obtained with solution (1), the area of any peaks corresponding to the desoxy impurity, the sulphoxide impurity, the ethyl ester impurity or the methyl ester impurity (identified by reference to the chromatograms obtained with solutions (4) to (7)) are not greater than the area of the principal peak in the chromatogram obtained with solution (2) (0.5%) and the sum of the areas of all the secondary peaks is not greater than twice the area of the principal peak in the chromatogram obtained with solution (2) (1%).


Weigh and powder 20  tablets. Shake a quantity of the powdered tablets containing 0.1  g of Sulindac with 80  ml of 0.1m methanolic hydrochloric acid for 10  minutes and dilute to 100  ml with the same solvent. Filter and dilute 3  ml of the filtrate to 200  ml with the same solvent. Measure the absorbance of the resulting solution at the maximum at 327  nm, Appendix II B, and calculate the content of C20H17FO3S taking 373 as the value of A(1%, 1  cm) at the maximum at 327  nm.
