Disopyramide Phosphate Capsules 

Action and use

Class I antiarrhythmic.

Definition

Disopyramide Phosphate Capsules contain Disopyramide Phosphate.


The capsules comply with the requirements stated under Capsules and with the following requirements.

Content of disopyramide, C21H29N3O

92.5  to 107.5% of the stated amount.
Identification

A.  Suspend a quantity of the contents of the capsules containing the equivalent of 0.2  g of disopyramide in 50  ml of chloroform, add 2  ml of 13.5m ammonia, shake and filter through anhydrous sodium sulphate. Evaporate the filtrate to dryness using a rotary evaporator and dissolve the residue in 2  ml of chloroform. The infrared absorption spectrum, Appendix II A, is concordant with the reference spectrum of disopyramide (RS 110).


B.  The light absorption, Appendix II B, in the range 230  to 350  nm of the solution obtained in the Assay exhibits a maximum only at 269  nm and a shoulder at 263  nm.


C.  Shake a quantity of the contents of the capsules containing the equivalent of 0.4  g of disopyramide with 20  ml of water and filter. The filtrate yields the reactions characteristic of phosphates, Appendix VI.

Tests

Dissolution

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 water and rotate the paddle at 50 revolutions per minute. Withdraw a sample of 10  ml of the medium and measure the absorbance of the filtered sample, suitably diluted if necessary, at the maximum at 262  nm, Appendix II B. Calculate the total content of disopyramide, C21H29N3O, in the medium taking 87 as the value of A(1%, 1  cm) at the maximum at 262  nm.


Related substances

Carry out the method for thin-layer chromatography, Appendix III A, using silica gel GF254 as the coating substance and a mixture of 1  volume of 18m ammonia, 30  volumes of acetone and 30  volumes of cyclohexane as the mobile phase. Apply separately to the plate 10 µl of each of the following solutions. For solution (1) shake a quantity of the contents of the capsules containing the equivalent of 0.20  g of disopyramide with 20  ml of methanol for 30  minutes and filter. For solution (2) dilute 1  volume of solution (1) to 200  volumes with methanol. After removal of the plate, allow it to dry in a current of 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) (0.5%).

Assay

To a quantity of the mixed contents of 20 capsules containing the equivalent of 40  mg of disopyramide, add 40  ml of 0.05m methanolic sulphuric acid, shake for 15  minutes, dilute to 100  ml with the same solvent and filter. Dilute 5  ml of the filtrate to 100  ml with 0.05m methanolic sulphuric acid and measure the absorbance of the resulting solution at the maximum at 269  nm, Appendix II B. Calculate the content of C21H29N3O taking 198.5 as the value of A(1%, 1  cm) at the maximum at 269  nm.

Labelling

The quantity of active ingredient is stated in terms of the equivalent amount of disopyramide.
