clozapine

an atypical ANTIPSYCHOTIC drug used in the treatment of schizophrenia and other disorders in patients who are unresponsive to conventional antipsychotics. Administered by mouth, it is notable for the absence of tremors and repetitive movements that are associated with other antipsychotic drugs. Side-effects include dizziness, headache, and increased salivation, and in a few cases the drug may depress levels of white blood cells.
