    Study Notes

    Flumazenil

    • Competitive antagonist at benzodiazepine receptors.
    • Used to prevent or reverse CNS effects of benzodiazepine overdose.
    • Accelerates recovery from benzodiazepines used in anesthetic and diagnostic procedures.
    • Precautions necessary for specific conditions:
      • Avoid use in drivers and machine operators requiring high attention.
      • Not recommended during pregnancy and lactation due to risks of fetal hypotonia.
      • Contraindicated in hepatic encephalopathy and respiratory depression.
      • Caution when combined with other CNS depressants like alcohol.

    Buspirone

    • Partial agonist targeting 5-HT1A receptors in the midbrain.
    • Selective anxiolytic without sedative or muscle relaxant properties.
    • Delayed anxiety suppression, typically occurring after 2 or more weeks.
    • Considered the preferred anxiolytic for the elderly.
    • Non-dependence forming medication.
    • Common adverse effects include dizziness, headache, tachycardia, and nervousness.

    Barbiturates

    • Largely replaced by safer alternatives such as benzodiazepines and SSRIs for anxiety and sleep disorders.
    • Phenobarbital: long-acting (6-8 hours), used as an anticonvulsant.
    • Thiopental: ultra-short-acting (15-20 minutes), utilized as an intravenous general anesthetic.
    • Mechanism of action:
      • GABA-like effects or enhancement of GABA at GABAA receptors, leading to increased Cl- conductance and hyperpolarization.
      • Non-selective action can result in generalized CNS depression with increased doses.
    • Therapeutic uses:
      • Insomnia management, though now mostly replaced by benzodiazepines.
      • Treatment for grand mal epilepsy.
      • Phenobarbital induces microsomal enzymes, aiding in the treatment of hyperbilirubinemia in neonates.
    • Adverse effects:
      • Potential for physical dependence.
      • Respiratory depression and myocardial depression in cases of acute toxicity.
      • Phenobarbital can precipitate acute intermittent porphyria symptoms due to increased porphyrin synthesis.

    Ramelteon

    • Prescribed for patients with difficulties in falling asleep.
    • Selective agonist targeting melatonin receptors MT1 and MT2 involved in sleep promotion and circadian rhythm regulation.
    • Adverse effects can include dizziness and fatigue.

    Chloral Hydrate

    • One of the oldest hypnotic drugs, an alcohol derivative.
    • Induces hypnosis within 30 minutes, effects lasting approximately 6 hours.
    • Primarily used as a hypnotic for children and the elderly prior to short surgical or dental procedures.
    • Current usage is very limited.

    Flumazenil

    • Competitive antagonist at benzodiazepine receptors.
    • Used to prevent or reverse CNS effects of benzodiazepine overdose.
    • Accelerates recovery from benzodiazepines used in anesthetic and diagnostic procedures.
    • Precautions necessary for specific conditions:
      • Avoid use in drivers and machine operators requiring high attention.
      • Not recommended during pregnancy and lactation due to risks of fetal hypotonia.
      • Contraindicated in hepatic encephalopathy and respiratory depression.
      • Caution when combined with other CNS depressants like alcohol.

    Buspirone

    • Partial agonist targeting 5-HT1A receptors in the midbrain.
    • Selective anxiolytic without sedative or muscle relaxant properties.
    • Delayed anxiety suppression, typically occurring after 2 or more weeks.
    • Considered the preferred anxiolytic for the elderly.
    • Non-dependence forming medication.
    • Common adverse effects include dizziness, headache, tachycardia, and nervousness.

    Barbiturates

    • Largely replaced by safer alternatives such as benzodiazepines and SSRIs for anxiety and sleep disorders.
    • Phenobarbital: long-acting (6-8 hours), used as an anticonvulsant.
    • Thiopental: ultra-short-acting (15-20 minutes), utilized as an intravenous general anesthetic.
    • Mechanism of action:
      • GABA-like effects or enhancement of GABA at GABAA receptors, leading to increased Cl- conductance and hyperpolarization.
      • Non-selective action can result in generalized CNS depression with increased doses.
    • Therapeutic uses:
      • Insomnia management, though now mostly replaced by benzodiazepines.
      • Treatment for grand mal epilepsy.
      • Phenobarbital induces microsomal enzymes, aiding in the treatment of hyperbilirubinemia in neonates.
    • Adverse effects:
      • Potential for physical dependence.
      • Respiratory depression and myocardial depression in cases of acute toxicity.
      • Phenobarbital can precipitate acute intermittent porphyria symptoms due to increased porphyrin synthesis.

    Ramelteon

    • Prescribed for patients with difficulties in falling asleep.
    • Selective agonist targeting melatonin receptors MT1 and MT2 involved in sleep promotion and circadian rhythm regulation.
    • Adverse effects can include dizziness and fatigue.

    Chloral Hydrate

    • One of the oldest hypnotic drugs, an alcohol derivative.
    • Induces hypnosis within 30 minutes, effects lasting approximately 6 hours.
    • Primarily used as a hypnotic for children and the elderly prior to short surgical or dental procedures.
    • Current usage is very limited.

    Flumazenil

    • Competitive antagonist at benzodiazepine receptors.
    • Used to prevent or reverse CNS effects of benzodiazepine overdose.
    • Accelerates recovery from benzodiazepines used in anesthetic and diagnostic procedures.
    • Precautions necessary for specific conditions:
      • Avoid use in drivers and machine operators requiring high attention.
