GENERIC NAME: ziprasidone


DRUG CLASS AND MECHANISM: Ziprasidone is an oral and injectable drug that is used for treating psychoses, for example, schizophrenia. Although the mechanism of action of ziprasidone is not known, like other anti-psychotics, it inhibits communication between nerves of the brain. It does this by blocking receptors on the nerves for several neurotransmitters, the chemicals that nerves use to communicate with each other. It is thought that the beneficial effect of ziprasidone is due to its blocking of dopamine and serotonin receptors. It also inhibits the re-uptake of serotonin and norepinephrine by nerves in the brain like some anti-depressant drugs. Ziprasidone is associated with little or no weight gain, a feature that distinguishes it from other anti-psychotic drugs. Similarly, ziprasidone is unique among anti-psychotic drugs in that it does not increase cholesterol levels. The FDA approved ziprasidone as a treatment for schizophrenia in February 2001.
