This is not the correct answer. Anti-muscarinic agents such as dicycloverine can be used to reduce gastrointestinal motility and associated symptoms seen in conditions such as irritable bowel syndrome (IBS) or diverticular disease. On the other hand, cimetidine is an H2 receptor antagonist. It competitively inhibits histamine in H2 receptors of parietal cells, suppressing the normal secretion of stomach acid from parietal cells, thus treating acid-related gastrointestinal conditions such as dyspepsia, peptic ulcer disease and gastro-oesophageal reflux disease.

Anti-muscarinic
QuestionChoice
This is the correct answer. Cimetidine is a H2 receptor antagonist. It competitively inhibits histamine in H2 receptors of parietal cells, suppressing the normal secretion of stomach acid from parietal cells, thus treating acid-related gastrointestinal conditions such as heartburn (dyspepsia), peptic ulcer disease and gastro-oesophageal reflux disease.

a
H2 receptor antagonist
QuestionChoice
This is not the correct answer. H1 receptor antagonists such as cyclizine are anti-emetics used to treat nausea and vomiting. On the other hand, cimetidine is an H2 receptor antagonist. It competitively inhibits histamine in H2 receptors of parietal cells, suppressing the normal secretion of stomach acid from parietal cells, thus treating acid-related gastrointestinal conditions such as heartburn (dyspepsia), peptic ulcer disease and gastro-oesophageal reflux disease.

b
H1 receptor antagonist
QuestionChoice
This is not the correct answer. Antacids such as aluminium hydroxide, calcium carbonate, sodium bicarbonate and so forth can come in liquid form or as chewable tablets. They neutralize stomach acid to relieve symptoms such as heartburn and dyspepsia, which this patient has. However, in this case, cimetidine was used which is a H2 receptor antagonist. It competitively inhibits histamine in H2 receptors of parietal cells, suppressing the normal secretion of stomach acid from parietal cells, thus treating acid-related gastrointestinal conditions such as dyspepsia, peptic ulcer disease and gastro-oesophageal reflux disease.

d
Antacid
QuestionChoice
This is not the correct answer. Mebeverine is an example of an antispasmodic used to relax intestinal smooth muscle, thus relieving symptoms associated with irritable bowel syndrome (IBS) such as crampy abdominal pain caused by intestinal spasms and bloating. On the other hand, cimetidine is an H2 receptor antagonist. It competitively inhibits histamine in H2 receptors of parietal cells, suppressing the normal secretion of stomach acid from parietal cells, thus treating acid-related gastrointestinal conditions such as dyspepsia, peptic ulcer disease and gastro-oesophageal reflux disease.
