Product Description

What is Cyproterone Acetate?

Cyproterone Acetate (abbreviated as CPA), sold alone under the brand name Androcur or with ethinylestradiol (EE) as Diane or Diane-35 among others, is an antiandrogen and progestogen that is used in the treatment of androgen-related conditions like acne, hirsutism (excessive hair growth), early-onset puberty, and prostate cancer, as a component of hormone therapy for transgender women, and in oral contraceptives. It is formulated and used both alone and in combination with an estrogen and is available for use both by mouth and by injection into muscle.

Cyproterone Acetate Usage

Androgen-dependent conditions

CPA is used in the treatment of prostate cancer, precocious puberty, androgen-dependent skin and hair conditions such as acne, seborrhea, hirsutism (excessive hair growth), and androgenic alopecia (pattern hair loss), hyperandrogenism (e.g., in PCOS), and to reduce sex drive in sex offenders or men with paraphilias or hypersexuality. CPA is also widely used as a component of hormone replacement therapy (HRT) for transgender women. 

In the treatment of acne in women, a formulation of low-dose CPA in combination with EE has been found to result in overall improvement in 75 to 90% of patients, with responses approaching 100% improvement.
