All of the following drugs causes hirsutism except:
**Core Concept**
Hirsutism is a condition characterized by excessive growth of body hair, particularly in women, due to increased **androgen** levels. Drugs that cause hirsutism typically do so by either increasing androgen production or mimicking the effects of androgens on the body.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general principle. Drugs that are known to cause hirsutism include **anabolic steroids**, **testosterone**, and certain **progestins** that have androgenic activity. These substances can lead to an increase in **dihydrotestosterone (DHT)**, a potent androgen that promotes hair growth.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific drug listed, we cannot provide a detailed explanation, but typically, drugs causing hirsutism would be those with androgenic effects.
**Option B:** Similarly, without the specific drug, we assume it could be a drug with androgenic properties.
**Option C:** Again, assuming this option is a drug that could lead to increased androgen activity.
**Option D:** This would presumably be the exception, a drug that does not cause hirsutism, possibly due to its lack of androgenic effects.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **spironolactone**, an **antiandrogen**, is actually used to treat hirsutism, highlighting the role of androgen blockade in managing this condition.
