MOA: Facilitate GABA by increasing frequency of Cl- channel opening
Decreases REM sleep

Clinical: anxiety, spasticity, status epilepticus (diazepam), detoxification from alcohol delirum tremens, general anesthetic (amnesia muscle relaxation), hypnotic (insomnia)
GOOD FOR ALCOHOL WITHDRAWAL, PRESURGERY ANXIETY

Diazepam and chlrodizepoxide are first line treatment for seizures assoicated with alcohol withdrawal

Toxicity: Less dependence (due to slower clearance), Higher daytime drowsiness (increased chance of falls), additive CNS ddepression effects with alcohol, less risk of respiratory depression and coma than barbiturates, sedation impairs coordination and balance (avoid in elderly) decreased memory and concentration

Avoid with alcohol, barbituates, neuroleptics and 1st gen antihistamines

Treat overdose with flumazenil (competitive antagonist at GABA benzodiazepine receptor)

Q

Despramine

A

MOA: block reuptake of NE and 5HT
Also block Na channels, Ach channels, alpha adrenergic, block histamine

LEAST SIDE EFFECTS, LEAST SEDATING

Toxicity: Sedation
alpha blocking: postural hypotension
Anticholinergic: dry mouth, tachycardia, urinary retention, Confusion and hallucinations in elderly, hyperthermia, dilated pupils
