The following helminthic disease can be treated by albendazole but not by mebendazole

Correct Answer: D

Rationale: Albendazole treats neurocysticercosis (unlike mebendazole) due to better CNS penetration.

Correct Answer: B

Rationale: First-line anti-TB drugs include isoniazid, rifampicin, ethambutol, and pyrazinamide. Cycloserine is a second-line drug used for resistant TB, not a first-line treatment.

Correct Answer: C

Rationale: Amphotericin B, nystatin, and griseofulvin are antibiotics derived from fungi, whereas miconazole is a synthetic azole antifungal, not an antibiotic.

Correct Answer: C

Rationale: Nystatin, like amphotericin B, binds ergosterol in Candida cell membranes, altering permeability and causing cell death, while ketoconazole inhibits ergosterol synthesis.

Correct Answer: B

Rationale: Isoniazid inhibits mycolic acid synthesis in Mycobacterium tuberculosis by targeting InhA and KatG, disrupting cell wall formation, a key mechanism in TB treatment.
