Steroidal antiandrogen
A steroidal antiandrogen (SAA) is an antiandrogen with a steroidal chemical structure. They are typically antagonists of the androgen receptor (AR) and act both by blocking the effects of androgens like testosterone and dihydrotestosterone (DHT) and by suppressing gonadal androgen production. SAAs lower concentrations of testosterone through simulation of the negative feedback inhibition of the hypothalamus. SAAs are used in the treatment of androgen-dependent conditions in men and women, and are also used in veterinary medicine for the same purpose.
Antimineralocorticoid
An antimineralocorticoid, also known as a mineralocorticoid receptor antagonist (MRA or MCRA) 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. Spironolactone, the first member of the class, is also used in the management of hyperaldosteronism (including Conn's syndrome) and female hirsutism (due to additional antiandrogen actions).
Drospirenone
Drospirenone is a progestin and antiandrogen medication which is used in birth control pills to prevent pregnancy and in menopausal hormone therapy, among other uses. It is available both alone under the brand name Slynd and in combination with an estrogen under the brand name Yasmin among others. The medication is an analog of the drug spironolactone. Drospirenone is taken by mouth. Common side effects include acne, headache, breast tenderness, weight increase, and menstrual changes.
Spironolactone
La spironolactone est un composé organo-sulfuré de la classe des stéroïdes, antagoniste de la principale hormone minéralocorticoïde, l'aldostérone, par compétition de liaison sur le récepteur des minéralocorticoïdes. Elle est à ce titre un anti-hypertenseur et un faible diurétique. Dans une moindre mesure la spironolactone est un antagoniste des androgènes sur leur récepteur. Elle est commercialisée sous les noms de Aldactone, Novo-Spiroton, Aldactazine, Spiractin, Spirotone, Verospiron ou Berlactone.
