Tamoxifen Tablets 

Action and use

Selective estrogen receptor modulator.

Definition

Tamoxifen Tablets contain Tamoxifen Citrate.

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

Content of tamoxifen, C26H29NO

90.0  to 110.0% of the stated amount.
Identification

A.  To a quantity of the powdered tablets containing the equivalent of 0.1  g of tamoxifen add 20  ml of water, warm, add 2  ml of 5m sodium hydroxide and cool. Extract with two 10-ml quantities of ether, filtering each extract in turn. Combine the ether extracts and evaporate to dryness in a current of nitrogen at room temperature. Dry the residue at a pressure not exceeding 0.7  kPa for 30  minutes. The infrared absorption spectrum of the dried residue, Appendix II A, is concordant with the reference spectrum of tamoxifen (RS 328).


B.  Shake a quantity of the powdered tablets containing the equivalent of 0.1  g of tamoxifen with 10  ml of methanol, filter, evaporate the filtrate to dryness on a water bath and dry the residue at 100° for 30  minutes. Dissolve 10  mg of the dried residue in 4  ml of pyridine, add 2  ml of acetic anhydride and heat on a water bath. A rose-pink to red colour is produced.

Tests

Related substances

E-Isomer and other related substances

Carry out the method for liquid chromatography, Appendix III D, protected from light and using the following solutions. For solution (1) to a quantity of the powdered tablets containing the equivalent of 50  mg of tamoxifen, add 35  ml of the mobile phase, mix with the aid of ultrasound for 5  minutes, dilute to 50  ml with the mobile phase, mix, centrifuge and filter the supernatant liquid through a membrane filter with a nominal pore size of 0.45 µm. For solution (2) dilute 1  volume of solution (1) to 100  volumes with the mobile phase. Solution (3) contains 0.15% w/v of tamoxifen citrate for performance test EPCRS in the mobile phase.


The chromatographic procedure may be carried out using (a) a stainless steel column (25  cm × 4.6  mm) packed with end-capped octadecylsilyl silica gel for chromatography (5 µm) (Columbus C18 is suitable), (b) as the mobile phase with a flow rate of 1.2  ml per minute a mixture of 40  volumes of acetonitrile and 60  volumes of water containing 0.09% w/v of sodium dihydrogen orthophosphate and 0.48% w/v of N,N-dimethyloctylamine, adjusted to pH 3.0 with orthophosphoric acid and (c) a detection wavelength of 240  nm.


Equilibrate the column with the mobile phase at a flow rate of 1.2  ml per minute for 30  minutes.


Adjust the sensitivity of the system so that the height of the peak due to the E-isomer in the chromatogram obtained with solution (3) is not less than 40% of the full scale of the recorder.


Inject 20 µl of each solution. Continue the chromatography for twice the retention time of the tamoxifen peak. The test is not valid unless the chromatogram obtained with solution (3) resembles that of the specimen chromatogram provided with the tamoxifen citrate for performance test EPCRS in that the resolution factor between the peaks due to the E-isomer and to tamoxifen impurity F is at least 3 and there is base-line separation of the peak due to tamoxifen impurity F from the following peak of the principal component.


In the chromatogram obtained with solution (1), the area of any peak due to the E-isomer is not greater than 0.3  times the area of the principal peak in the chromatogram obtained with solution (2) (0.3%) and the sum of the areas of all the secondary peaks apart from any peak due to the E-isomer is not greater than 0.5  times the area of the principal peak in the chromatogram obtained with solution (2) (0.5%). Disregard any peak with a retention time of less than 2.5  minutes and any peak with an area less than 0.05  times the area of the principal peak in the chromatogram obtained with solution (2) (0.05%).


Dissolution

Comply with the requirements for Monographs of the British Pharmacopoeia in the dissolution test for tablets and capsules, Appendix XII B1, using as the medium 1000 ml of 0.02m hydrochloric acid and rotating the basket at 150 revolutions per minute. Withdraw a sample of 5 ml of the medium. Measure the absorbance of the filtered sample, suitably diluted if necessary, at 275 nm, Appendix II B. Calculate the total content of C26H29NO in the medium taking 305 as the value of A(1%, 1 cm) at 275 nm.

Assay

Weigh and powder 20  tablets. To a quantity of the powder containing the equivalent of 25  mg of tamoxifen add 100  ml of methanol, shake for 15  minutes and add sufficient methanol to produce 250  ml. Filter, dilute 10  ml of the filtrate to 100  ml with methanol and measure the absorbance of the resulting solution at 275  nm, Appendix II B. Calculate the content of C26H29NO taking 325 as the value of A(1%, 1  cm) at 275  nm.

Storage

Tamoxifen Tablets should be protected from light.

Labelling

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