ABSTRACT
The effects of the antiandrogen drugs cyproterone acetate (CPA) and
spironolactone on hair growth and androgen levels were compared in a randomized
study of 48 hirsute women. Twenty six subjects completed 6 months of therapy
with 100 mg/day CPA and 19 subjects completed 6 months of 100 mg/day
spironolactone. All except 10 subjects received concomitant estrogen therapy.
Measured objectively, total hair diameter fell by 17.1% with spironolactone (P
less than 0.001), and by 16.8% with CPA (P less than 0.001). The diameter of
the hair medulla fell by 17.8% with spironolactone (P less than 0.01), and by
31.7% with CPA (P less than 0.001). There was no difference between the drugs
in their effect on hair diameter. Plasma testosterone levels also fell
significantly with both drugs. As a subjective assessment of treatment
efficacy, the frequency with which subjects performed cosmetic measures was
recorded. This fell by 38% with spironolactone and by 44.7% with CPA (P less
than 0.001 both drugs), and again there was no difference between the drugs.
Side effects caused cessation of treatment in one subject taking CPA and two
subjects taking spironolactone, and milder side effects were noted in two
further subjects from each treatment group. We conclude that spironolactone and
CPA, in the dosages used in this study, are effective and well tolerated agents
for the treatment of hirsutism, and that neither drug demonstrates a particular
advantage over the other. (AUTHOR)
