(latest update)
Examples of PD medications by class - answer Levodopa: dopamine
substitiue: converts to dopamine in body
MAO-B inhibs: inhibits MAO-B from breaking down dopamine
Dopamine agonists: lengthen duration of action of idiopathic or synthetic
dopamine in CNS
COMT inhibs: in CNS or PNS inhibit enzyme that breaks down dopami
What else can bromocriptine, amantadine, and diphenhydramine be used
for: - answer bromocriptine (menstrual problems, growth hormone over
production, pituitary tumors, stops breast milk production, control blood
sugars),
amantadine (antiviral; influenza type A)
diphenhydramine (allergic rxn, motion sickness).
What is the advantage of Sinemet over levodopa? Sinemet = carbadopa +
levodopa. - answer Carbadopa stops peripheral conversion of levodopa to
dopamine, preserving it for when it crosses the blood brain barrier where
levodopa is best used. Carbadopa does not cross the blood brain barrier.
This also has the benefit of decreased symptoms of nausea.
Which Parkinson's medication is an MAO inhibitor, and what patient
education is necessary because of this?
