Benzydamine Cream 

Action and use

Cyclo-oxygenase inhibitor; analgesic; anti-inflammatory.


Benzydamine Cream contains Benzydamine Hydrochloride in a suitable basis.

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

Content of benzydamine hydrochloride, C19H23N3O,HCl

92.5  to 107.5% of the stated amount.


A.  Heat a quantity of the cream containing 25  mg of Benzydamine Hydrochloride with 50  ml of absolute ethanol until the cream is completely dissolved and place in an ice-bath until a white precipitate forms. Allow to warm to 20°, dilute to 100  ml with absolute ethanol and filter. Dilute 10  ml of the filtrate to 100  ml with absolute ethanol. The light absorption of the resulting solution, Appendix II B, in the range 230  to 350  nm exhibits a maximum at 308  nm.

B.  In the test for 1-Benzyl-1H-indazol-3-ol, the principal spot in the chromatogram obtained with solution (1) corresponds to that in the chromatogram obtained with solution (2).



Carry out the method for thin-layer chromatography, Appendix III A, using the following solutions in methanol.

(1)  Extract a quantity of the cream containing 60  mg of Benzydamine Hydrochloride with 25  ml of hot methanol, cool the solution in ice and filter; repeat the extraction twice, filtering each extract and evaporate the combined extracts to dryness using a rotary evaporator; dissolve the residue in 5  ml of methanol.

(2)  1.2% w/v of benzydamine hydrochloride BPCRS.

(3)  0.0024% w/v of 1-benzyl-1H-indazol-3-ol BPCRS.

chromatographic conditions

(a)  Use as the coating silica gel GF254.

(b)  Use the mobile phase as described below.

(c)  Apply 40 µl of each solution.

(d)  Develop the plate to 15 cm.

(e)  After removal of the plate, dry in air and examine under ultraviolet light (254  nm and 365  nm).

mobile phase

30  volumes of triethylamine and 80  volumes of toluene.


By each method of visualisation, any secondary spot in the chromatogram obtained with solution (1) is not more intense than the spot in the chromatogram obtained with solution (3) (0.2%).


To a quantity of the cream containing 25  mg of Benzydamine Hydrochloride add 50  ml of ethanol (96%), heat until the cream is completely dissolved and cool in an ice-bath until a white precipitate forms. Allow to warm to 20°, dilute to 100  ml with ethanol (96%) and filter. Dilute 10  ml of the filtrate to 100  ml with ethanol (96%) and measure the absorbance of the resulting solution at the maximum at about 308  nm, Appendix II B, using ethanol (96%) in the reference cell. Calculate the content of C19H23N3O,HCl from the absorbance obtained with a solution containing 0.0025% w/v of benzydamine hydrochloride BPCRS in ethanol (96%) and using the declared content of C19H23N3O,HCl in benzydamine hydrochloride BPCRS.

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.
