These included medical therapies, such as cinnarizine or cinnarizine/dimenhydrinate, citicoline, thiethylperazine
, delorazepam or clonazepam, sulodexide, nimodipine, lipoflavonoid cereals, and levosulpiride, as well as hospital admission for intravenous mannitol or glycerol.
These agents were found to be more effective as an antiemetic compared with prochlorperazine, metoclopramide, chlorpromazine, thiethylperazine
, haloperidol, domperidone, or alizapride.
For example, thiethylperazine
(DB00372) is an antagonist of human Dopamine D3 (hDRD3_170) according to the description in Pet[s.sub.k]o and Ringe  which shows that the prediction result is meaningful, and other remaining unknown DTIs deserve being validated in the future.
In thirty randomized studies, cannabinoids were found to be more effective than prochlorpromazine, thiethylperazine
, metoclopramide, haloperidol, domperidone and alizapride, but not effective with very low or very highly emetogenic chemotherapy agents.
