What kind of pill is white, round with M on 1 side, 732 on the other?

Not Medical Advice: "M 732" is Ondansetron hydrochloride (orally disintegrating) 4 mg. It's white and round. Ondansetron hydrochloride is a selective blocking agent of the serotonin 5-HT3 receptor type. It's used in the treatment of nausea/vomiting, as well as radiation therapy induced nausea/vomiting.

Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells by damaging their DNA.

A group of more than 120 cancer researchers and physicians has just published a research paper taking aim at pharmaceutical prices, describing them as being "exorbitant and unjustifiable". The paper, which was published online in the American Society of Hematology's medical journal Blood, analyzes and criticizes the cost of drugs used to treat chronic myeloid leukemia, a rare type of cancer that responds very well to drug therapy. The Blood authors say that lowering the prices will help save the lives of patients who cannot afford to pay for the drugs that are used to treat chronic myeloid leukemia.
