Correct Answer is B

Explanation

Choice A rationale

Cholinergic agonists primarily stimulate the parasympathetic nervous system rather than the central nervous system, affecting activities like digestion, salivation, and decreased heart rate.

Choice B rationale

Parasympathetic nervous system is the correct answer. Cholinergic agonists mimic acetylcholine and stimulate parasympathetic responses, promoting rest-and-digest functions such as reducing heart rate and enhancing glandular secretions.

Choice C rationale

The sympathetic nervous system is not stimulated by cholinergic agonists. Instead, this system is activated by adrenergic agonists, which prepare the body for fight-or-flight responses, increasing heart rate and blood pressure.

Choice D rationale

Voluntary nervous system control is not the primary target of cholinergic agonists. This system governs skeletal muscle movement and is influenced by neuromuscular junctions rather than the autonomic responses modulated by cholinergic drugs. .

A. Sumatriptan (Imitrex). B. Naratriptan (Amerge). C. Frovatriptan (Frova). D. Almotriptan (Axert).

Correct Answer is A

Explanation

Choice A rationale

Sumatriptan (Imitrex) is a selective serotonin receptor agonist that helps constrict blood vessels in the brain and is typically used to treat migraine and cluster headaches. Its effectiveness is due to its ability to reduce inflammation and alleviate the pain associated with these headaches.

Choice B rationale

Naratriptan (Amerge) is also a triptan used for the treatment of migraines but is not specifically indicated for cluster headaches.

Choice C rationale

Frovatriptan (Frova) is used mainly for the acute treatment of migraine headaches and is not indicated for cluster headaches.

Choice D rationale

Almotriptan (Axert) is used to treat migraines and does not have an indication for cluster headaches.
