Skip phase 1
treat alcoholics with lorazepam or oxazepam because it is easier on their liver
buspirone
General Anxiety Disorder
Non-benzodiazepine anxiolytic
None of the negative side-effects seen in Benzos
Not effective if patient has been exposed to Benzos in the past
Triazolam
Short 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive Shortest onset
Oxazepam
Short 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive No first pass metabolism
Temazepam
Short 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive Very powerful No first pass metabolism
Alprazolam (Xanax)
Short 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive Very powerful
Lorazepam

Short 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive
Clonazepam
Long 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) unique 7-membered hetero-ring structure Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive
Chlordiazepoxide (librium)
Long 1/2 life Benzodiazepine (positive allosteric modulator of GABA-A receptor, increases flow of Cl- when GABA binds) unique 7-membered hetero-ring structure Anxiolytic Sedative/hypnotic muscle relaxant anticonvulsant addictive Fast acting (30-60 min)

Flumazenil
Treats Benzodiazepine Overdose
Antagonist @ benzodiazepine recognition site
causes increased anxiety, seizures in animal studies
Pentobarbitol
Anxiolytic
Barbiturate
prolonged opening of Ion channel at GABA-A receptor Complex
Can be too strong
Amobarbitol
Anxiolytic
Barbituate
prolonged opening of Ion channel at GABA-A receptor Complex
Benzodiazepine/Barbiturate Side Effects
Dependence
excessive sedation
respiratory depression (especially with overdose/use in conjunction with other drugs, alcohol)
Withdrawal symptoms include increased risk for seizures
