The exact mechanism of this interaction is not well-defined, but it has been theorized that this effect may be due to, among many other causes, inhibition of prostaglandin synthesis, anti-inflammatory effects, immunosuppressive effects antiemetic effects of ondansetron and dexamethasone.

Lancet 1991 Aug 24 Both dexamethasone and ondansetron, a serotonin antagonist recently approved by the FDA, have been successfully used to prevent the nausea and vomiting induced by either dexamethasone 8 mg and ondansetron 4 mg (n =60) or ramosetron 0.3 mg (n =60).

This leads me to suppose that the antiemetic effect is not from hte steroid structure but must be a 3-dimensional moiety of In addition to its antiemetic efficacy, dexamethasone has been shown to have other beneficial effects. De Oliveira et al. 5 analysed 24 randomised controlled trials (n = 2751) published between 1997 and 2010 and concluded that an intermediate dose (0.11–0.2 mg. kg −1 ) of dexamethasone conferred significant benefits in early as well as late pain. Conclusion: Dexamethasone 4 mg or bethamethasone 12 mg did not provide prolonged post‐operative analgesic effect compared with ketorolac 30 mg, which was superior for analgesia and antiemesis in the PACU. 2017-02-15 · CONCLUSIONS Primary aprepitant as an addition to MEC demonstrated efficacy in improving digestive symptoms in the delayed phase.

Ketamine has unique central sympatho-mimetic, vagolytic and analgesic properties . These effects of ketamine are assumed to reduce the incidence of spinal induced hypotension and consequently nausea and vomiting. The exact mechanism of the granisetron-dexamethasone combination in increasing the complete response (no PONV, no rescur) is not known, but it has been suggested that granisetron may act on sites containing 5-HT 3 receptors with demonstrated antiemetic effects , and that dexamethasone may inhibit the synthesis of prostaglandin, which is related to the trigger of emesis . Dexamethasone is a corticosteroid with antiemetic and high anti-inflammatory effects. Use of dexamethasone in combination with the other drugs has been reported to increase the antiemetic or analgesic ef ficacy, and minimal side efects have been reported when it is used as a single agent 13-16.
