Antipsychotic Drugs

Antipsychotic drugs are categorized into first- and second-generation agents.
First-generation drugs are further classified as low-potency or high-potency based on their affinity for dopamine D2 receptors, which affects their side effects.
First-generation antipsychotics are competitive inhibitors at various receptors, but their antipsychotic effect is linked to blocking dopamine D2 receptors.
Second-generation antipsychotics have fewer extrapyramidal symptoms (EPS) compared to first-generation drugs, but are associated with a higher risk of metabolic side effects like diabetes, high cholesterol, and weight gain.
Second-generation drugs likely work by blocking both serotonin and dopamine receptors (and possibly others).
Clozapine is an effective antipsychotic with minimal EPS risk.
Clozapine's use is limited to resistant cases due to significant side effects like bone marrow suppression, seizures, and cardiovascular issues.
Frequent monitoring of white blood cell counts is crucial due to the risk of agranulocytosis (a serious blood disorder) with clozapine.
