Schizophrenia medication refers to the pharmacological agents used to treat schizophrenia, a chronic psychiatric disorder characterized by psychosis, disorganized thinking, and impaired perception of reality. The mainstay of treatment is the class of antipsychotic drugs, which act principally by modulating dopaminergic neurotransmission, most notably antagonism or partial agonism at dopamine D2 receptors, with many agents also acting on serotonergic and other receptor systems. These medications are broadly grouped into first-generation, or typical, antipsychotics and second-generation, or atypical, antipsychotics, the latter generally associated with a lower propensity for movement-related side effects but a greater liability for metabolic disturbance. They are most effective against positive symptoms such as hallucinations and delusions, while negative and cognitive symptoms typically respond less completely. Treatment-resistant illness may warrant specific agents reserved for that indication. A central clinical concern is the long-term safety profile of these drugs, particularly metabolic adverse effects including weight gain, obesity, dyslipidemia, insulin resistance, and the metabolic syndrome, which elevate cardiovascular risk and influence adherence. Effective management therefore integrates pharmacotherapy with metabolic monitoring, lifestyle and nutritional intervention, psychosocial support, and attention to the knowledge and involvement of patients and caregivers. Research addresses efficacy, tolerability, adherence, and strategies to mitigate the physical-health burden of antipsychotic treatment.
