A Itraconazole B Oseltamivir C Acyclovir D Amphotericin B 3 ANSWER C — Acyclovir — Acyclovir is the drug of choice for both herpes simplex virus (HSV) and varicella-zoster virus (VZV) infections.

It works by binding to ergosterol in the fungal cell membrane, creating pores that increase membrane permeability and cause cell death. It is a broad-spectrum antifungal used for serious systemic fungal infections. Azoles (option B) are a separate antifungal class that inhibit ergosterol synthesis. n Source Image Q92 Which statement best describes the comparative efficacy of SNRIs and SSRIs?

The choice between them is often guided by side effect profiles, comorbid conditions (e.g., SNRIs may be preferred for comorbid pain), and individual patient response rather than superior antidepressant efficacy. n Source Image Q34 How does levodopa enter the brain to exert its therapeutic effects?
