Abstract: Synergistic compositions for inhibiting the action of androgens comprise the combination in a single topical preparation of a 5.alpha.-reductase enzyme inhibitor and an androgen receptor blocking agent in a pharmaceutically and dermatologically acceptable vehicle. The compositions may be topically applied to affected areas of the skin in the treatment or prevention of sebaceous gland hypertrophy, hirsutism and male-pattern baldness in mammals. The inhibitor and blocking agent are present in the composition in a weight ratio of about 1:20 to 5:1, with the inhibitor comprising up to about 0.1% w/v of the composition and the blocking agent comprising up to about 1% w/v of the composition.

Abstract: Steroid compounds of the 20-spiroxane series and their analogues having an open ring E of the formula, ##STR1## in which --A--A-- represents the group --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--,R.sup.1 represents hydrogen, andR.sup.2 represents an .alpha.-oriented lower alkoxycarbonyl radical, orR.sup.1 and R.sup.2 together represent an .alpha.- or a .beta.-oriented methylene radical,--B--B-- represents the group --CH.sub.2 --CH.sub.2 -- or an .alpha.- or .beta.-oriented group ##STR2## X represents two hydrogen atoms or oxo, Y.sup.1 and Y.sup.2 together represent the oxygen bridge --O--, orY.sup.1 represents hydroxy, andY.sup.2 represents hydroxy, lower alkoxy or, if X represents H.sub.2, also lower alkanoyloxy,and salts of compounds in which X represents oxo and Y.sup.2 represents hydroxy, are distinguished as effective aldosterone-antagonists with minimal side-effects and, for that reason, are especially suitable for the treatment of all forms of hyperaldosteronism.

Abstract: Topical pharmaceutical compositions containing a corticosteroid component and a penetration-enhancing vehicle are disclosed. The vehicle comprises a binary combination of a C.sub.3 -C.sub.4 diol and a "cell-envelope disordering compound". The vehicle provides marked transepidermal and percutaneous delivery of corticosteroids. A method of treating certain rheumatic and inflammatory conditions, systemically or locally, is also disclosed.

Abstract: (5.alpha.)-20-spirox-1-en-3-ones (I) and 17-hydroxy-5.alpha.,17.alpha.-pregn-1-en-3-ones (II) of the formulae ##STR1## in which X represents O or H.sub.2, R.sub.2 represents O and R.sub.1 represents OH, OMe, OAlk, NH.sub.2, NHR.sub.3, NR.sub.3 R.sub.4, or R.sub.2 represents H.sub.2 and R.sub.1 represents OH, OAlk, OAr, OAralk or OAc,in which R.sub.3, R.sub.4 and Alk represent lower alkyl, Me represents a metal atom or metal equivalent or the cation of an organic base, Ar represents monocyclic aryl, Aralk represents monocyclic aryl-lower alkyl, and Ac represents lower alkanoyl, monocyclic aroyl, lower alkylsulphonyl or monocyclic arylsulphonyl, it being possible for R.sub.3 together with R.sub.4 also to represent a lower alkylene group optionally interrupted by a hetero atom,are manufactured by known analogy processes.
