Tick the drug belonging to lincozamides:

Correct Answer: B

Rationale: The correct answer is B: Lincomycin. Lincomycin belongs to the lincosamides class of antibiotics, which also includes clindamycin. Lincomycin works by inhibiting bacterial protein synthesis. Erythromycin (A) is a macrolide antibiotic, not a lincosamide. Azithromycin (C) is another macrolide antibiotic. Aztreonam (D) is a monobactam antibiotic, not a lincosamide. Therefore, the correct answer is B because it is the only drug belonging to the lincosamides class.

Correct Answer: A

Rationale: The correct answer is A: Praziquantel. Praziquantel is the drug of choice for treating neurocysticercosis as it is effective against the tapeworm causing this condition. It works by affecting the tapeworm's cell membrane, leading to paralysis and death of the parasite. Pyrantel is used for treating intestinal parasites, not neurocysticercosis. Piperazine is used for treating roundworm infections. Bithionol is used for treating certain types of flukes. Therefore, the most appropriate choice for neurocysticercosis treatment is praziquantel due to its effectiveness against the tapeworm causing the condition.

Correct Answer: B

Rationale: The correct answer is B: Anastrozole. Aromatase inhibitors block the enzyme aromatase, which converts androgens into estrogens. Anastrozole specifically inhibits aromatase, reducing estrogen levels. Octreotide (A) is a somatostatin analogue, Flutamide (C) is an androgen receptor antagonist, and Tamoxifen (D) is a selective estrogen receptor modulator (SERM), not an aromatase inhibitor. Thus, the only drug among the choices that directly targets aromatase is Anastrozole.

Correct Answer: C

Rationale: The correct answer is C: Lovastatin. Lovastatin is a statin drug that inhibits HMG-CoA reductase, a key enzyme in cholesterol synthesis. It is effective in reducing LDL cholesterol levels and decreasing the risk of cardiovascular events. Niacin (choice A) is also used for hyperlipidemia but has more side effects. Cholestyramine (choice B) is a bile acid sequestrant used for high cholesterol but is less effective than statins. Nicotinamide (choice D) is a form of vitamin B3 and is not indicated for hyperlipidemia.
