Novel retinoic acid esters of anti-inflammatory steroids of the pregnane series are described and their use in the treatment and control of acne vulgaris via the topical or intralesional route.

Pharmaceutical formulations and methods for the manufacture of the novel steroidal retinoates are also described.
