Question: 1 / 400

Which of the following belongs to the class of anti-spasmodic agents?

Atropine

Atropine is classified as an anti-spasmodic agent because it works by blocking the action of acetylcholine, a neurotransmitter that can cause muscle contractions in the smooth muscle of the gastrointestinal tract and other areas. By inhibiting these contractions, atropine helps to relieve spasms and reduce motility in the digestive system, making it effective in treating conditions characterized by excessive muscle contractions, such as irritable bowel syndrome.

In contrast, the other medications listed—esomeprazole, omeprazole, and rabeprazole—are all proton pump inhibitors primarily used to reduce stomach acid production. These drugs are effective in treating conditions like gastroesophageal reflux disease (GERD) and peptic ulcers but do not have anti-spasmodic properties. Their primary mechanism is to inhibit the proton pump in the stomach lining, thereby decreasing acid secretion rather than affecting muscle contraction.
