Which of the following is 5-HT receptor antagonist?
The first-generation 5-HT3 receptor antagonist (ondansetron, dolasetron, granisetron, and tropisetron) have been the most important drugs in antiemetic therapy for emetogenic chemotherapy. They are especially effective in treating acute emesis, occurring in the first 24 hours following chemotherapy.
Is Ginger a serotonin antagonist?
Ginger is effective in alleviating nausea and emesis, particularly, for cytotoxic chemotherapy drug-induced emesis. Ginger-mediated antiemetic effect has been attributed to its pungent constituents-mediated inhibition of serotonin (5-HT) receptor activity but its cellular mechanism of action is still unclear.

- Prevention of radiation therapy-induced nausea and vomiting.
- Prevention of postoperative nausea and vomiting.
Is Prozac an antagonist?
Our results show that fluoxetine is a competitive and reversible antagonist of 5HT2C receptors and suggest that some therapeutic effects of fluoxetine may involve blockage of 5HT receptors, in addition to its known blockage of 5HT transporters.
Are antidepressants antagonist?

Is cisapride an HT antagonist?
Cisapride is a serotonin 5-HT4 receptor agonist and 5-HT3 receptor antagonist that increases gastrointestinal motility by augmenting cholinergic transmission through the myenteric plexus.
Do SSRIs reduce serotonin receptors?
SSRIs block the reabsorption (reuptake) of serotonin into neurons. This makes more serotonin available to improve transmission of messages between neurons. SSRIs are called selective because they mainly affect serotonin, not other neurotransmitters.
What supplements raise serotonin levels?
Instead, people can turn to natural supplements to increase serotonin.
- Tryptophan. L-tryptophan, shortened to tryptophan, is a precursor to serotonin production.
- SAMe (S-adenosyl-L-methionine)
- 5-HTP (5-hydroxytryptophan)
