    Study Notes

    Antipsychotic Drugs: Key Points

    • Before antipsychotic drugs, treatments for schizophrenia included crude and horrifying methods like trepanation, exorcism, and extermination.
    • The incidence of schizophrenia is approximately 1%, and many states had hospitals exclusively for its treatment, such as Pilgrim State Hospital in New York.
    • Pilgrim State Hospital, initially designed for 12,500 patients on 1,900 acres, held a peak population of 16,000 patients, making it the largest psychiatric hospital in the world.
    • Antipsychotics have rapid calming effects within hours to a few days, with marked differences in potency and effective doses.
    • Antipsychotic drugs are categorized into two major groups: "1st generation" (FGA) and "2nd generation" (SGA) antipsychotics.
    • "1st generation" antipsychotics are further classified as "low potency" or "high potency," based on dopamine receptor blockade.
    • The first "2nd generation" antipsychotic, clozapine, was approved in 1972 but removed from the market in 1975 due to causing agranulocytosis in ~1% of patients.
    • Clozapine was reintroduced in 1989 with strict guidelines and found use in managing treatment-resistant patients with fewer movement and neuroendocrine side effects.
    • Risperidone (1995), olanzapine (1996), and quetiapine (1997) were developed as clozapine-like agents, with eight additional SGAs approved since then.
    • FDA-approved antipsychotic drugs include "azines" and "dols," and some have been withdrawn due to cardiac arrhythmias.
    • Specific properties of SGAs are categorized based on receptor affinity, sedation, extrapyramidal symptoms, hyperprolactinemia, and partial agonist effects.
    • Antipsychotic drugs have varied effects on dopaminergic pathways in the brain, impacting movement disorders, arousal, sensory processing, behavior control, and prolactin secretion.
