Which of the following medicines are associated with side effect of sexual dysfunction?
**Core Concept**
The question is testing the association between certain medications and the side effect of sexual dysfunction, which is a common issue in patients taking various classes of drugs. Sexual dysfunction can manifest as erectile dysfunction (ED), decreased libido, or anorgasmia, among others.
**Why the Correct Answer is Right**
Medications that affect the central nervous system, particularly those that interact with the dopaminergic and serotonergic pathways, can lead to sexual dysfunction. For instance, **Selective Serotonin Reuptake Inhibitors (SSRIs)**, such as fluoxetine, can decrease sexual desire and arousal by inhibiting serotonin reuptake in the brain. Additionally, drugs that block alpha-1 adrenergic receptors, like **Prazosin**, can cause priapism, a condition characterized by prolonged erections. **Option C:** **SSRIs** are correct because they are well-known to cause sexual side effects in a significant proportion of patients.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify a particular medication. While many medications can cause sexual dysfunction, the question asks for a specific example.
* **Option B:** This option is incorrect because it mentions a medication that is not commonly associated with sexual dysfunction. **Metformin** is a first-line treatment for type 2 diabetes and is not known to cause significant sexual side effects.
**Clinical Pearl / High-Yield Fact**
When evaluating a patient with sexual dysfunction, it's essential to ask about their medication list, as certain medications can exacerbate or cause these issues. A thorough history and physical examination can help identify underlying causes and guide treatment.
**Correct Answer:** C. SSRIs
