200
1. Blocks Na+ channels
2. Inhibits reuptake of monoamines

200
Inhibits 5-HT and NE reuptake
Venlafaxine, Desvenlafaxine, Duloxetine, Levomilinacipran, Milnacipran
MOA of SNRIs?
Name 2
200

MOA of second generation/atypical antipsychotics?
200
Ebstein's anomaly
What is a fetal abnormality that may be caused by lithium use during pregnancy?
300
Naloxone
Short acting opioid antagonist
What medication would you give someone who overdosed on opioids?
300
Hyperalert, decreased need for sleep, tachycardia, HTN, pupillary dilation, fever, agitation, chest pain, seizures
Signs of amphetamine intoxication?
300
Seizure, coma (due to antagonism of GABA) hyperthermia/skin flushing, dilated pupils and urinary retention (due to anticholinergic toxicity), hypotension (due to alpha blockade), prolonged QT
How would someone present if they overdosed on TCAs?
300
Parkinsonian like symptoms, hyperprolactinemia
Dry mouth, constipation, hypotension, sedation (because 5-HT, histamine, NE, and Ach may also be blocked because they are so structurally similar to dopamine)
Side effects of first generation/typical antipsychotics?
300
Euphoria, increased appetite, slurred speech, impaired judgement, anxiety/panic attacks
How would a patient on marijuana present?
400
CNS: Pain relief, euphoria, sedation, respiratory depression, cough suppression, miosis
PNS: Constipation, skin warmth/flushing
What are the CNS and PNS effects of opioids?
400
Increased energy, decreased need for sleep, hyperalert, euphoric, hallucinations (usually tactile), fever, anxiety, paranoia, dilated pupils, tachycardia, chest pain
Signs of cocaine intoxication?
400
Infusion of sodium bicarbonate
Sodium overcomes the NA+ blockade in heart
Sodium bicarb raises pH -> favors inactive form of drug
How would you treat an TCA overdose?
400
7-10 days after treatment is started pt will experience mental status changes, fever and rigid muscles. Labs will show increased creatinine kinase due to damaged muscles and myoglobinuria due to acute renal failure.
What is neuroleptic malignant syndrome?
400
Euphoria, alertness, bruxism (teeth grinding), hyperthermia
How would a patient on ecstasy present?
500
Presynaptic: Close Ca2+ channels (reduces neurotransmitter release)
Postsynaptic: Open K+ channels (hyperpolarization)
Overall Effect: Less signal transduction
What is the MOA of opioids?
(Presynaptic and postsynaptic)
500
Benzodiazepines
Avoid beta blockers in cocaine intoxication because it can cause increased and unopposed alpha effects which can worsen HTN and chest pain

500
MAO inhibitors
Causes 3 A's
Agitation, Autonomic hyperactivity, Neuromuscular hyperActivity
