It appears to be safe during pregnancy but has not been well studied in this group. [8] It is a serotonin 5-HT 3 receptor antagonist. [8] It does not have any effect on dopamine receptors or muscarinic acetylcholine receptor and therefore does not cause akathisia. [11] Ondansetron was patented in 1984 and approved for medical use in 1990. [12]
However, not all of them are safe to use during pregnancy. One of the components of bismuth subsalicylate is salicylate, which is a component that crosses the placenta. Due to this, there is an increased risk for intrauterine growth retardation, fetal hemorrhage, and maternal hemorrhage within organogenesis and in the second/third trimester. [ 12 ]
The 5-HT 3 receptor was later found to correspond to the M receptor. [34] In the 1970s, John Fozard found that metoclopramide and cocaine were weak antagonists at the 5-HT 3 (5-HT-M) receptor. Fozard and Maurice Gittos later synthesized MDL 72222, the first potent and truly selective 5-HT 3 receptor antagonist.

[3] [6] Cyclizine was discovered in 1947. [8] It is on the World Health Organization's List of Essential Medicines. [9] In the United States it is available over the counter. [6]
Hyperemesis gravidarum (HG) is a pregnancy complication that is characterized by severe nausea, vomiting, weight loss, and possibly dehydration. [1] Feeling faint may also occur.
