Q

how is lithium excreted

A

kidneys, most reabsorbed at PCT following Na+ reabsorption

32
Q

TCA – What is special about desipramine

A

less sedating and has higher seizure threshold

58

65
Q

MAO inhibitors – contraindications and why

A

contraindicated w/ SSRIs, TCAs, St. Johns wort, meperidine, dextromethorphan to prevent serotonin syndrome
