Ulobetasol was granted FDA approval on 17 December 1990.

Ultravate (Westwood-Squibb).

Pharmacokinetics

Corticosteroids bind to the glucocorticoid receptor, inhibiting pro-inflammatory signals, and promoting anti-inflammatory signals. Ulobetasol has a moderate duration of action as it is applied once or twice daily. Corticosteroids have a wide therapeutic window as patients may require doses that are multiples of what the body naturally produces. Patients taking corticosteroids should be counselled regarding the risk of hypothalamic-pituitary-adrenal axis suppression and increased susceptibility to infections.
