Review Article

Summary

Attempts to develop selective (“magic bullet”) drugs for the treatment of schizophrenia have been frustrated by the complex etiology of the disease. The symptomatology of schizophrenia does not appear to arise from a single neurobiological entity, but rather may be derived from pathology at one or more receptor types. This has prompted multifactorial approaches to the development of new therapeutics, as embodied by polypharmacy and an alternative (or augmentative) strategy known as ldintramolecular polypharmacy,” in which a single drug possesses the capacity to affect multiple receptor types. Atypical antipsychotics are a well-known example of this approach; each atypical possesses a unique portfolio of activities at receptors that may contribute to therapeutic effects (as well as side effects). In this article we present a discussion of some of the receptor targets that are currently thought to mediate symptoms of schizophrenia, as well as their possible implications for the design of future multifunctional antipsychotics.
