What does a Transient Ischemic attack warn of? - ANS ✔✔impending stroke: "brain angina"
Levodopa action - ANS ✔✔precursor to dopamine, converted in brain and peripheral tissue to dopamine
Levodopa contraindications - ANS ✔✔glaucoma, caution with heart, renal, liver, endocrine diseases,
MAO inhibitors (depression med)
Adverse Effects of Levodopa - ANS ✔✔anorexia, nausea & vomiting, liver toxicity, orthostatic
hypotension, tachycardia, Headache, anxiety, restlessness, agitation, depression, psychosis, suicidal,
dyskinesia
Nursing Implications of Levodopa - ANS ✔✔•Takes 6-8 weeks to be effective
•Do not take with oral iron supplements or Vit. B6
•Do not eat high protein meals at time take med
•Take with a meal or after to reduce nausea
Action of carbidopa - ANS ✔✔•blocks peripheral biotransformation in liver and periphery (carboxylation)
of levodopa so more reaches brain
Use of carbidopa - ANS ✔✔•given with levodopa to decrease dosage needed
Nursing Implications of carbidopa - ANS ✔✔•Sinemet is combination levodopa & carbidopa
•CR form- do not crush
•Taken up to 6 X/day (half life 1-3 hours)
•Caution drowsiness, dizziness
•After 5 years decreased therapeutic effects
Action of benztropine mesylate (Cogentin) - ANS ✔✔•restores balance of dopamine and cholinergic
levels in brain
Adverse Effects of Benztropine mesylate - ANS ✔✔•sedation, CNS, cardiac, dry mouth, constipation,
urinary retention
•avoid extreme environmental temperatures
•effectiveness lessens over time; so if increase dose = increased adverse effects
Action of aspirin - ANS ✔✔inhibits COX- enzyme in thromboxane
Nursing Implications of aspirin - ANS ✔✔patients who have asthma, allergies, and nasal polyps or who
are allergic to tartrazine are at an increased risk for developing hypersensitivity reactions
