Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/12893841 | https://www.ncbi.nlm.nih.gov/pubmed/15212312 | http://adisinsight.springer.com/drugs/800016206

Etiprednol dicloacetate (BNP-166; ethyl-17alpha-dichloroacetoxy-11beta-hydroxyandrosta-1,4-diene-3-one-17beta-carboxylate) is a new soft steroid. The compound proved to be a dissociated glucocorticoid, showing a reduction in transactivating activity while preserving transrepressive abilities. The compound effectively decreased cytokine production in lipopolysaccharide-stimulated lymphocytes and attenuated lectin-induced proliferation of blood mononuclear cells in tissue culture. The significant local effect of the compound will very likely be accompanied by a drastically reduced systemic activity indicating an encouraging selectivity of the pharmacological action of etiprednol dicloacetate. Etiprednol dicloacetate had been in a clinical trial for the treatment of allergic rhinitis, asthma and Crohn's disease. However, development has been discontinued.
