Treatment With An Anti-psychotic Drug Found To Cause Changes In Metabolism Earlier Than Expected

Schizophrenia is a complex type of psychotic mental illness characterized by thoughts that are uncoupled from reality. Huge gains in the effective treatment of individuals with the disease began in the 1950s with the development of the first generation of antipsychotic drugs. The medications allowed physicians to treat the “positive” effects of the illness (delusions and hallucinations) and, to a lesser extent, the “negative” symptoms (apathy). The second generation of antipsychotics – known as atypical antipsychotics (AAP) – began in 1990. These newer medicines have proven as effective in treating the positive aspects of the disease and more effective in combating the negative ones.

As is the case with nearly all medications, antipsychotics have side affects, including weight gain and some other risk factors of metabolic syndrome, which puts an individual at greater risk of heart disease and type 2 diabetes. Physicians are concerned that these side effects may cause their patients to stop taking their medicine.

A team of French researchers has found, in an animal model, that the consumption of at least one atypical antipsychotic exhibits some of the risks for metabolic syndrome in humans. This model allows researchers to explore the sequence of early metabolic events that may result from atypical medications.
