postdetox for relapse prevention
used in patients with liver disease
topiramate

reduces cravings for alcohol
drug that mimics schizo
amphetamine psychosis
flumazenil

barb overdose treatment
alkalinize urine with sodium bicarb to promote renal excretion
naloxone
treatment of choice for opiate overdose
opioid producing large pupils

Miosis
methadone
long acting opioid receptor agonist
- use in pregnant women
- can cause QTc prolongation
