An assessment of thiethylperazine (Torecan) in the control of radiation-induced nausea and vomiting.

A double-blind trial was undertaken to compare thiethylperazine (Torecan) and pyridoxine as anti-emetics in patients undergoing externally applied radiotherapy to the abdomen and pelvis. The patients who received thiethylperazine experienced fewer or much milder symptoms than those given pyridoxine.
