Phenindione Tablets 

Action and use

Oral anticoagulant (indanedione).

Definition

Phenindione Tablets contain Phenindione.

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

Content of phenindione, C15H10O2

92.5  to 107.5% of the stated amount.
Identification

A.  Shake a quantity of the powdered tablets containing 0.2  g of Phenindione with 50  ml of chloroform, filter and evaporate the filtrate to dryness. The infrared absorption spectrum of the residue, Appendix II A, is concordant with the reference spectrum of phenindione (RS 268).


B.  Recrystallise the residue obtained in test A from ethanol (96%), dissolve 20  mg in 10  ml of ethanol (96%) with the aid of heat, cool, dilute to 250  ml with 0.1m sodium hydroxide and dilute 5  ml to 100  ml with 0.1m sodium hydroxide. The absorbance of the resulting solution at the maximum at 278  nm is about 0.54 and at 330  nm is about 0.16, Appendix II B.

Tests

Related substances

Carry out in subdued light the method for thin-layer chromatography, Appendix III A, using a silica gel F254 precoated plate (Merck silica gel 60 F254 plates are suitable) and as the mobile phase a solution containing 0.02% w/v of butylated hydroxytoluene in a mixture of 4  volumes of glacial acetic acid, 20  volumes of ethyl acetate and 80  volumes of toluene. Allow the solvent front to ascend 4  cm, remove the plate and dry it in a current of cold air for 1  minute. Without delay apply separately to the plate 10 µl of each of the following solutions and develop immediately. For solution (1) shake a quantity of the powdered tablets containing 50  mg of Phenindione with 15  ml of dichloromethane, filter, evaporate the filtrate to dryness and dissolve the residue in 5  ml of dichloromethane. For solution (2) dilute 1  volume of solution (1) to 50  volumes with dichloromethane. For solution (3) dilute 1  volume of solution (1) to 200  volumes with dichloromethane. After removal of the plate, allow it to dry in a current of warm air and examine under ultraviolet light (254  nm). Any secondary spot in the chromatogram obtained with solution (1) is not more intense than the spot in the chromatogram obtained with solution (2) (2%) and not more than one such spot is more intense than the spot in the chromatogram obtained with solution (3) (0.5%).


Uniformity of content

Tablets containing 50  mg or less of Phenindione comply with the requirements stated under Tablets using the following method of analysis. Place one tablet in 50  ml of 0.1m sodium hydroxide, dissolve the tablet completely by shaking gently, add a further 100  ml of 0.1m sodium hydroxide and shake for 1  hour. Dilute to 250  ml with 0.1m sodium hydroxide, filter and dilute a portion of the filtrate with sufficient 0.1m sodium hydroxide to produce a solution containing 4 µg of Phenindione per ml. Measure the absorbance of the resulting solution at the maximum at 278  nm, Appendix II B. Calculate the content of C15H10O2  taking 1310 as the value of A(1%, 1  cm) at the maximum at 278  nm.

Assay

Weigh and powder 20  tablets. Shake a quantity of the powder containing 50  mg of Phenindione with 150  ml of 0.1m sodium hydroxide for 1  hour, add sufficient 0.1m sodium hydroxide to produce 250  ml, filter and dilute 5  ml of the filtrate to 250  ml with 0.1m sodium hydroxide. Measure the absorbance of the resulting solution at the maximum at 278  nm, Appendix II B. Calculate the content of C15H10O2  taking 1310 as the value of A(1%, 1  cm) at the maximum at 278  nm.
