Tick the drug, a derivative of adamantane:

Correct Answer: B

Rationale: The correct answer is B: Rimantadine. Rimantadine is a derivative of adamantane due to its molecular structure containing an adamantane core. This structural similarity allows rimantadine to exert antiviral activity against influenza A viruses by inhibiting the viral uncoating process. Didanozine (A) is a nucleoside reverse transcriptase inhibitor used in HIV treatment, not related to adamantane. Gancyclovir (C) and Foscarnet (D) are antiviral drugs used for treating herpesvirus infections and cytomegalovirus infections, respectively, but they are not derivatives of adamantane.

Correct Answer: A

Rationale: The correct answer is A: Propranolol. Propranolol is a non-selective beta-blocker that can potentially cause vasoconstriction, increased blood pressure, and decreased oxygen supply to the heart, leading to myocardial infarction (MI) in susceptible individuals. Nitroprusside (B) and Nitroglycerin (C) are vasodilators that help improve blood flow and decrease cardiac workload, making them unlikely to cause MI. Nifedipine (D) is a calcium channel blocker that primarily affects blood vessels and the heart, but it is less likely to cause MI compared to propranolol.
