Opioids | Stimulants | Antidepressants | Antipsychotics | Other |
---|---|---|---|---|
Restlessness, yawning, rhinorrhea, lacrimation, piloerection
What are the withdrawal symptoms of opioids?
|
Increase dopamine and norepinephrine in the CNS
What is the MOA of amphetamines?
|
Inhibits 5-HT reuptake
Fluoxetine, Fluvoxamine, Paroxetine, Sertraline, Escitalopram, Citalopram
MOA of SSRIs?
Name 1 |
Block D2 receptors
MOA of first generation/typical antipsychotics?
|
Nephrogenic diabetes insipidus
Adverse effect of lithium on kidneys
|
Altered mental status, decreased respiratory rate, decreased bowl sounds, miosis, seizures
How would someone present if they overdosed on opioids?
|
1. Blocks Na+ channels
2. Inhibits reuptake of monoamines
What is the MOA of cocaine? (2 answers)
|
Inhibits 5-HT and NE reuptake
Venlafaxine, Desvenlafaxine, Duloxetine, Levomilinacipran, Milnacipran
MOA of SNRIs?
Name 2 |
Decrease 5-HT2A activity (significant serotonin blocking effects)
MOA of second generation/atypical antipsychotics?
|
Ebstein's anomaly
What is a fetal abnormality that may be caused by lithium use during pregnancy?
|
Naloxone
Short acting opioid antagonist
What medication would you give someone who overdosed on opioids?
|
Hyperalert, decreased need for sleep, tachycardia, HTN, pupillary dilation, fever, agitation, chest pain, seizures
Signs of amphetamine intoxication?
|
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?
|
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?
|
Euphoria, increased appetite, slurred speech, impaired judgement, anxiety/panic attacks
How would a patient on marijuana present?
|
CNS: Pain relief, euphoria, sedation, respiratory depression, cough suppression, miosis
PNS: Constipation, skin warmth/flushing
What are the CNS and PNS effects of opioids?
|
Increased energy, decreased need for sleep, hyperalert, euphoric, hallucinations (usually tactile), fever, anxiety, paranoia, dilated pupils, tachycardia, chest pain
Signs of cocaine intoxication?
|
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?
|
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?
|
Euphoria, alertness, bruxism (teeth grinding), hyperthermia
How would a patient on ecstasy present?
|
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) |
Benzodiazepines
Avoid beta blockers in cocaine intoxication because it can cause increased and unopposed alpha effects which can worsen HTN and chest pain
How would you treat cocaine and amphetamine intoxication?
*What should you avoid in cocaine intoxication? |
MAO inhibitors
Causes 3 A's Agitation, Autonomic hyperactivity, Neuromuscular hyperActivity
Which antidepressant is a classic cause of serotonin syndrome?
|
Dantrolene (muscle relaxant) or bromocriptine (dopamine agonist)
How do you treat neuroleptic malignant syndrome?
|
Synesthesia (hear colors), depersonalizations
*Can see flashbacks after (Effects of LSD after stopping drug)
How would a patient on LSD present?
|
