    Study Notes

    5-HT Receptors

    • There are four families of 5-HT receptors: 5-HT1, 5-HT2, 5-HT3, and 5-HT4-7
    • Within these families, there are 14 receptor subtypes
    • 5-HT3 receptor antagonists are used for relieving itching associated with skin disorders such as allergic dermatitis
    • Common adverse effects of 5-HT3 receptor antagonists include drowsiness, dry mouth, confusion, ataxia, and weight gain
    • Granisetron and Tropisetron are selective 5-HT3 antagonists
    • Prochlorperazine and haloperidol are anti-5-HT agents sometimes used for resistant acute attacks of schizophrenia
    • Ketanserin selectively blocks 5-HT2 receptors with minimal effects on 5-HT1, 5-HT3, and 5-HT4 receptors
    • Clozapine, an atypical antipsychotic, blocks both 5-HT6 and 5-HT7 receptors
    • The central nervous system (CNS) is implicated in depression and hallucination
    • Olanzapine and risperidone, atypical antipsychotics, block 5-HT2A and 5-HT2C receptors in the CNS
