Description
Curator's Comment: description was created based on several sources, including https://www.accessdata.fda.gov/drugsatfda_docs/label/2017/017531s014lbl.pdf | http://www.sciencedirect.com/science/article/pii/B9781416002086500231 | https://www.ncbi.nlm.nih.gov/pubmed/23002952

Trimethobenzamide (trade names Tebamide, Tigan) is an antiemetic used to prevent nausea and vomiting. Trimethobenzamide is an antagonist of the D2 receptor, that affects the chemoreceptor trigger zone (CTZ) of the medulla oblongata to suppress nausea and vomiting. The oral bioavailability of trimethobenzamide is 60% to 100%. The time to peak is about 45 minutes after oral administration and; I.M. about 30 minutes after intramuscular administration. The onset action of trimethobenzamide for antiemetic effects is 10-40 minutes after oral administration and; 15-35 minutes after intramuscular administration. The duration of action is 3-4 hours. Trimethobenzamide is generally considered the most potent antiemetic that does not have effects on the serotonergic, dopaminergic, or histaminergic systems, so it has a lower likelihood of causing undesired side effects. Possible side effects include drowsiness, dizziness, headache, diarrhea, muscle cramps, and blurred vision. More serious adverse effects include skin rash, tremors, parkinsonism, and jaundice.

Route of Administration: Other
Rat embryos were used for activity evaluation. Embryos were explanted on day 9.5 of gestation and cultured. Whole rat serum was used as a culture medium for the control group while different concentrations of dimenhydrinate (2.5–20 lg/ml), metoclopramide (10–50 lg/ml) and trimethobenzamide HCl (25–100 lg/ml) were added to serum for the experimental groups.
