How Does Kytril Work?

Nausea and vomiting are complex processes involving many chemicals in the body and several parts of the body, including the brain and the small intestine.

It is likely that Kytril works in the small intestine, but it may also work in the brain.

Kytril works by blocking serotonin, a chemical produced by the body that is associated with nausea and vomiting. Serotonin has many effects in the body and has several receptors where it can bind. This medication blocks serotonin at a specific type of receptor (the 5-HT3 receptor), which is important for nausea and vomiting. It has no effects on other types of serotonin receptors in the body.
