All of the following are used in management of hirsutism except.
**Core Concept**
Hirsutism is a condition characterized by excessive hair growth in women, typically on the face, chest, and back. It is often caused by an excess of androgens, such as testosterone. The management of hirsutism involves various pharmacological and non-pharmacological interventions aimed at reducing androgen levels or their effects.
**Why the Correct Answer is Right**
The management of hirsutism often involves a combination of medications that reduce androgen production, block androgen effects, or prevent hair growth. **Spironolactone**, a potassium-sparing diuretic, is an example of a medication that blocks the effects of androgens by antagonizing the androgen receptor. **Flutamide**, a nonsteroidal antiandrogen, is another medication used to treat hirsutism by blocking androgen receptors. **Finasteride**, a 5-alpha-reductase inhibitor, reduces the conversion of testosterone to dihydrotestosterone (DHT), a potent androgen that contributes to hirsutism.
**Why Each Wrong Option is Incorrect**
**Option A:** **Metformin** is actually used in the management of hirsutism, particularly in women with polycystic ovary syndrome (PCOS), as it helps to reduce insulin resistance and androgen production.
**Option B:** **Cyproterone acetate** is a medication used to treat hirsutism by blocking the effects of androgens and reducing androgen production.
**Option C:** **Eflornithine** is a topical cream used specifically to treat hirsutism by inhibiting the enzyme ornithine decarboxylase, which is involved in hair growth.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the management of hirsutism should be individualized, taking into account the underlying cause, severity of symptoms, and potential side effects of medications.
**Correct Answer:** D.
