Clobetasone Cream 

Action and use

Glucocorticoid.

Definition

Clobetasone Cream contains Clobetasone Butyrate in a suitable basis.


The cream complies with the requirements stated under Topical Semi-solid Preparations and with the following requirements.

Content of clobetasone butyrate, C26H32ClFO5

90.0  to 110.0% of the stated amount.
Identification

A.  Carry out the method for thin-layer chromatography, Appendix III A, using silica gel 60 GF254 as the coating substance and a mixture of 5  volumes of absolute ethanol, 10  volumes of acetone and 100  volumes of chloroform as the mobile phase. Apply separately to the plate 10 µl of each of the following solutions. For solution (1) disperse a quantity of the cream containing 0.5  mg of Clobetasone Butyrate in a mixture of 5  volumes of ethanol (80%) and 10  volumes of n-hexane, taking 15  ml of the solvent mixture for each g of cream. Shake the mixture, allow to separate, filter the aqueous layer and add 1  ml of water for every 10  ml of n-hexane used. Cool the solution in ice for 30  minutes, centrifuge, filter the supernatant liquid and dilute with 10  ml of water for every 10  ml of n-hexane used. Add 1  g of sodium chloride for every 10  ml of water used and extract with 5  ml of chloroform for every 10  ml of water used. Evaporate the chloroform layer to dryness in a current of dry nitrogen with gentle heating and dissolve the residue in 0.5  ml of chloroform. Solution (2) contains 0.1% w/v of clobetasone butyrate BPCRS in chloroform. Solution (3) contains a mixture of equal volumes of solutions (1) and (2). After removal of the plate, allow it to dry in air and examine under ultraviolet light (254  nm). The principal spot in the chromatogram obtained with solution (1) corresponds to that in the chromatogram obtained with solution (2). The principal spot in the chromatogram obtained with solution (3) appears as a single compact spot.


B.  In the Assay, the chromatogram obtained with solution (2) shows a peak with the same retention time as the peak due to clobetasone butyrate in the chromatogram obtained with solution (1).

Assay

caution Carry out the preparation of solutions (2) and (3) with full facial protection and wearing heat-resistant gloves.


Carry out the method for liquid chromatography, Appendix III D, using the following solutions. Solution (1) contains 0.004% w/v of clobetasone butyrate BPCRS and 0.0028% w/v of clobetasol propionate BPCRS (internal standard) in ethanol (50%). For solution (2) add 10  ml of absolute ethanol to a quantity of the cream containing 1  mg of Clobetasone Butyrate. Stopper firmly using a plastic stopper and heat on a water-bath with intermittent shaking until the cream is completely dispersed. Cool the contents in ice for 30  minutes, centrifuge and dilute 5  ml of the supernatant liquid to 10  ml with water. Prepare solution (3) in the same manner as solution (2) but adding 5  ml of absolute ethanol and 5  ml of a 0.014% w/v solution of the internal standard in absolute ethanol. Solutions (2) and (3) may assume a gel-like appearance.


The chromatographic procedure may be carried out using (a) a stainless steel column (10  cm × 4.6  mm) packed with octadecylsilyl silica gel for chromatography (5 µm) (Spherisorb ODS 1 is suitable) and maintained at 60°, (b) as the mobile phase with a flow rate of 2  ml per minute a mixture of 40  volumes of absolute ethanol and 60  volumes of water and (c) a detection wavelength of 241  nm. The proportions of the mobile phase may be adjusted to give a retention time for clobetasone butyrate of about 5.5  minutes.


Calculate the content of C26H32ClFO5 in the cream using peak areas and the declared content of C26H32ClFO5 in clobetasone butyrate BPCRS.

Storage

Clobetasone Cream should be stored at a temperature not exceeding 30°.




The packaging can be customized. the shipping term can be by sea, by air, and sample or small quantity can be shipped by DHL, FEDEX, EMS and TNT.
