This was just recently answered , so I'll just copy paste (for the thousandth time) . In short , TLDR :
------------------------------------------------------------------------------------
The reasoning for that :
Other AEs? | Don't use –
- Ondansetron/Zofran
- Diphenhydramine/Benadryl
- Dimenhydrinate/Dramamine
Serotonin or Histamine only are not as effective.
Read guide ; List of AE by type – dopamine antagonists (Wikipedia) |
Why not Ondansetron? | "Metoclopramide is used by Dignitas and i think it's the recommened antiemetic in OD, the second one being domperidone, both dopamine antagonists. Ondansetron (Zofran) is a serotonin receptor antagonist and it's used for cancer patients undergoing chemotherapy because the irritation of the GI mucosa by the medication used in chemotherapy (which is cytotoxic and increase the levels of serotonin in the blood) are transmitted through the vagal nerve to the chemoreceptor trigger zone via activating serotonin receptors (5-HT3). It has no effect on dopamine receptors. " |
In simple words? | Need broad systematic AE targeting both CTZ (brain) and stomach plus prokinetic. |
How vomiting works | Complex interactions:
- Chemoreceptor Trigger Zone
- Vomiting Centre
- Nucleus Tractus Solitarius
- GI tract chemoreceptors
