Anti-nausea drug to help cancer patients

Cancer patients in the US are about to get help in preventing the vomiting that can be debilitating during chemotherapy - a pill that blocks nausea impulses in the brain. The US Food and Drug Administration has cleared the sale of Emend, the first drug approved to prevent delayed nausea.

Vomiting and subsequent dangerous weight loss can be so severe that some patients cannot tolerate what could be lifesaving cancer treatment.
