    Study Notes

    Benzodiazepines

    • Most important group of medications
    • Provide anxiolysis (reduction of anxiety)
    • Cause sedation (relaxation or sleepiness)
    • Reduce muscle tone (relax muscles)
    • Produce anterograde amnesia (inability to form new memories)
    • Have anticonvulsant effects (prevent or reduce seizures)
    • Act on GABA-A receptors (specific target in the brain)
    • Midazolam is an example of a benzodiazepine
