Betamethasone cream

Heat a mixture of items 1-5 and item 6 separately to about 80°C. 

Heat items 7 and 8 until the active ingredient is dissolved, mix with above mixture, and continue to stir to cool to room temperature. This creates a white cream.

These related chlorinated phenols are used as preservatives in betamethasone cream, electrocardiogram paste, and in over 30 over-the counter products. Contact allergic eczema does occur sporadically. The two compounds may cross-react (Hjorth and Trolle Lassen 1963 Burry et al. 1975 Storrs 1975).

Excellent separations of corticosteroids can be achieved on an ODS column with a suitable ratio of methanol/water as an eluent. In this assay hydrocortisone is quantified using betamethasone as an internal standard. The structure of betamethasone is close to that of hydrocortisone but since it is more lipophilic it elutes from the ODS column after hydrocortisone (Fig. 12.12). The assay is a modification of the BP assay for hydrocortisone cream. In the assay described here the internal standard is added at the first extraction step rather than after extraction has been carried out in order to ensure that any losses in the course of sample preparation are fully compensated for. Extraction is necessary in the case of a cream because the large amount of oily excipients in the basis of the cream would soon clog up the column if no attempt was made to remove them. The corticosteroids are sufficiently polar to remain in the methanol/water layer as they have a low solubility in hexane, while the oily excipients are removed by extraction into hexane. The sodium chloride (NaCl) is included in the sample extraction solution to prevent the formation of an emulsion when the extract is shaken with hexane. Solution 2, where the internal standard is omitted, is prepared in order to check that there are no excipients in the sample which would interfere with the peak due to the internal standard.
