What is the mode of action of domperidone?

What is the mode of action of domperidone?

The DA2-receptor antagonist domperidone antagonizes the inhibitory effect of dopamine, resulting in stimulation of gastric muscle contraction. This provides a mechanism for the gastrokinetic effect of domperidone.

What is the classification of domperidone?

Domperidone belongs to the group of medications called dopamine antagonists. It is used to treat slowed movement in the gastrointestinal tract associated with diabetes and gastritis (inflammation of the stomach lining).

What is the indication of domperidone?

What is the mode of action of pantoprazole?

Pantoprazole exerts its stomach acid-suppressing effects by preventing the final step in gastric acid production by covalently binding to sulfhydryl groups of cysteines found on the (H+, K+)-ATPase enzyme at the secretory surface of gastric parietal cell.

What is the difference between domperidone and metoclopramide?

Domperidone is a motility modifier once used in people, but withdrawn because of cardiac arrhythmias. It has actions similar to metoclopramide, although it is chemically unrelated. A difference between metoclopramide and domperidone is that the latter does not cross the blood–brain barrier.

What is the mechanism of action of domperidone?

Domperidone acts as a gastrointestinal emptying (delayed) adjunct and peristaltic stimulant. The gastroprokinetic properties of domperidone are related to its peripheral dopamine receptor blocking properties.

How does domperidone interact with CYP3A4?

Interactions. Domperidone is almost exclusively metabolized by CYP3A4, and for this reason, inhibitors and inducers of this enzyme may alter the metabolism and concentrations of domperidone. Moreover, domperidone has been identified as a modest mechanism-based (irreversible) inhibitor of CYP3A4 (K = 12 μM),…

Does domperidone cross the blood-brain barrier in Parkinson’s disease?

Domperidone can be used to relieve gastrointestinal symptoms in Parkinson’s disease; it blocks peripheral D2 receptors but does not cross the blood–brain barrier in normal doses (the barrier between the blood circulation of the brain and the rest of the body) so has no effect on the extrapyramidal symptoms of the disease.

Which drugs increase the plasma concentration of domperidone?

Itraconazole and ketoconazole, both used to treat fungal infections, are potent CYP3A4 inhibitors and increase the plasma concentration of domperidone.
