They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.
A mineralocorticoid receptor antagonist (MRA or MCRA) [1] or aldosterone antagonist, is a diuretic drug which antagonizes the action of aldosterone at mineralocorticoid receptors. This group of drugs is often used as adjunctive therapy, in combination with other drugs, for the management of chronic heart failure .

[28] [16] In addition, the AR antagonism of spironolactone is involved in its feminizing side effects, such as gynecomastia in men. [28] Spironolactone has been found to produce gynecomastia without changes in testosterone or estradiol levels, implicating AR antagonism in this side effect. [30] Gynecomastia is a major known side effect of AR ...
For people with hyperplasia of both glands, successful treatment is often achieved with spironolactone or eplerenone, drugs that block the aldosterone receptor. With its antiandrogen effect, spironolactone drug therapy may have a range of side effects in males and females, including gynecomastia and irregular menses. These symptoms occur less ...
