title: Iatrogenic disorders associated with conventional vs. atypical antipsychotics.
abstract: Pharmacotherapy is an indispensable component of the management of schizophrenia and related psychotic disorders. Antipsychotic drugs are used for their efficacy in controlling the symptoms of psychosis. However, the side effects of antipsychotic drugs can have a deleterious impact on the course of the illness by inducing iatrogenic symptoms of various severity. The side effects of first-generation or conventional antipsychotic drug were often so intolerable to patients with schizophrenia that their compliance was consistently poor, leading to frequent relapse, chronicity, and impaired functioning. The second-generation (atypical) antipsychotics, introduced 40 years after the advent of the older-generation, are proving to have better outcomes in psychosis not only because of broader symptom efficacy but also because their side-effect profile is more tolerable, leading to higher compliance and fewer relapses. The authors review the side effects of the old and the new antipsychotics and conclude that the improved tolerability of the new antipsychotics is associated with greater effectiveness, not just efficacy. Differences in tolerability among the new antipsychotics are described.
