Abstract
Nausea and vomiting are frequent symptoms in emergency medicine and require a targeted drug intervention. Despite known disadvantages in terms of efficacy and side effects, metoclopramide is still often used in the emergency medical service to treat nausea and vomiting. Recent studies show that, especially in the therapy of opioid-triggered vomiting, metoclopramide is not significantly effective when compared to placebo. Dimenhydrinate seems to be an effective drug for various forms of nausea, but can often be relatively or absolutely contraindicated in emergency medicine due to its sedative effect. Based on a literature review, 5-HT3-antagonists appear to be a good alternative for the treatment of emesis in the emergency service. However, as for all antiemetics, the maximum dosage and potential side effects need to be paid attention to. In addition, neither of the 5-HT3-antagonists are approved for therapy of non-chemotherapy-induced vomiting or PONV. In conclusion, it may be considered to include 5-HT3-antagonists in addition to dimenhydrinate in the ambulance medical equipment. The routine use of a specific antiemetic is not recommended.
