Which of the following drugs is used for candidiasis treatment:

Correct Answer: C

Rationale: Miconazole is an azole antifungal effective against candidiasis by inhibiting ergosterol synthesis, while griseofulvin targets dermatophytes, nitrofungin is less common, and streptomycin is an antibiotic.

Correct Answer: D

Rationale: Terbinafine, amphotericin B, and ketoconazole are fungicidal, killing fungi. Miconazole is typically fungistatic, inhibiting growth rather than killing, though it can be fungicidal at high doses.

Correct Answer: B

Rationale: Isoniazid depletes vitamin B6 (pyridoxine), causing peripheral neuritis (tingling, numbness), a common side effect preventable with B6 supplementation. (Note: Options were inferred as the question was incomplete.)

Correct Answer: B

Rationale: Rimantadine inhibits the M2 ion channel of influenza A, preventing uncoating of viral RNA, thus blocking viral replication.

Correct Answer: B

Rationale: Rimantadine prevents influenza A by inhibiting the M2 ion channel, blocking viral uncoating, making it effective for prophylaxis.
