The possible use of these compounds in the treatment of androgenic alopecia and male pattern baldness in women is proposed, but not substantiated.
  • GB 1 538 227 describes compounds of formula (I):
  • Rj is a C* ⁇ _5 alkyl group, a C ⁇ ⁇ .Q alkenyl group, a C ⁇ .g cycloalkyl group, or a phenylalkyl group in which the alkyl moiety contains 1 to 3 carbon atoms and the phenyl moiety is optionally substituted;
  • R2 is a hydroxyl group, or a group OR4 wherein R4 is a C2-7 alkanoyl group, a CJL_4 alkyl group, or an optionally substituted benzyl group; and R3 is hydrogen or a C ⁇ _5 alkyl group; or 2 and R3 together with the carbon atom to which they are joined represent a carbonyl group.
  • Optional substituents for phenyl moieties include C ⁇ _4 alkyl, halogen and nitro.
  • i is a methyl, ethyl or n- or i ⁇ o-propyl group, and most preferably a methyl group.
  • 2 is a hydroxyl group.
  • Variable R2 suitably has the ⁇ -configuration.
  • R3 is hydrogen or methyl, and most preferably hydrogen.
  • GB 1538 227 discloses a pharmaceutical composition
  • a pharmaceutical composition comprising a compound of formula (I) together with a pharmaceutically acceptable carrier, for topical or oral administration.
  • GB 1538 227 describes a preferred composition for topical administration to the skin as comprising a compound of formula (I) which has been formulated as a cream or ointment using conventional formulations well known in the art, for example as described in standard text books of pharmaceutics and cosmetics, such as Harry's Cosmeticology and the British Pharmacopoeia-
  • compositions according to the present invention are considered to have utility in arresting hair-loss, female hirsuitism, in promoting hair-growth, in the treatment of acne, and in reducing excessive secretion of sebum from the sebaceous glands in particular as a cosmetic treatment for greasy skin and hair.
  • a topically administrable composition comprising a compound of formula (I) as hereinbefore defined and a topically acceptable carrier which includes a volatile solvent and a non- volatile solvent wherein the composition is specifically adapted to present a compound of formula I to a site of action on the skin or scalp in a substantially saturated or supersaturated concentration such that penetration of the skin or scalp is promoted, characterised in that the non ⁇ volatile solvent is isopropyl isosterate or a non-volatile mixture containing isopropyl isosterate.
  • a particularly preferred compound of formula (I) for use in compositions of the present invention is the compound androst-4-ene-16,16-dimethyl-17 ⁇ -ol- 3-one.
  • the volatile solvent is selected from a volatile alcohol such as ethanol or propan-2-ol, a volatile oil such as a volatile silicone fluid, and mixtures thereof.
  • the topically acceptable carrier may further comprise further a less-volatile or non-volatile co-solvent. It is not necessary for the compound of formula (I) to be readily soluble in the co-solvent but it will be appreciated that the ratio of volatile solvent to co-solvent will generally be selected to solubilise the compound of formula (I).
  • less-volatile co-solvents include benzyl alcohol dimethicone silicone oil and water.
  • non-volatile co-solvents include propylene glycol, polyethylene glycol, non-volatile silicone fluids and Arlasolve DMI (dimethyl iso-sorbide).
