Following are effective against tinea versicolor EXCEPT:
**Core Concept**
Tinea versicolor is a superficial fungal infection caused by Malassezia species, leading to hyperpigmentation and scaling on the skin. Effective treatments aim to eliminate the fungus and restore skin pigmentation.
**Why the Correct Answer is Right**
The correct treatment options for tinea versicolor typically involve antifungal agents that target the cell membrane of the fungus, such as azoles (e.g., ketoconazole, fluconazole) and polyenes (e.g., clotrimazole). These medications inhibit the synthesis of ergosterol, an essential component of the fungal cell membrane.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a commonly used treatment for tinea versicolor. **Option B:** This option is incorrect because it is not effective against Malassezia species, which are responsible for tinea versicolor. **Option C:** This option is incorrect because it is not typically used as a first-line treatment for tinea versicolor.
**Clinical Pearl / High-Yield Fact**
It is essential to note that tinea versicolor can be challenging to treat, and relapses are common. Therefore, it is crucial to use a combination of topical and systemic antifungal agents, as well as to maintain good skin hygiene and sun protection.
**Correct Answer: C.**
