2)ability to tolerate side effects
In Parkinson's, what happens to dopamine and cholinergic levels in the body?
There is decreased dopaminergic activity and increased cholinergic activity.
what are 3 therapeutic strategies for treating Parkinson's?
1) increase dopamine concentration and receptor activity
2) inhibit the metabolism/breakdown of dopamine
3) anticholinergic drugs (reduce cholingergic activity, as an adjunctive therapy
In Parkinson's, can use of drugs eliminate or cure the disease?
NO! drugs can reduce symptoms and improve condition, but cannot fix the problem
what is the name of the drug used in PK that is a metabolic precursor of dopamine?
what drug used in PK is a dopamine agonist?
bromocriptine (parlodel)
what drug for PK inhibits metabolism of dopamine?
selegiline (eldepryl)
what drug used in PK is an anticholinergic?
benztropine (cogentin)
an example of a monoamine oxidase inhibitor is:

-used as an adjunct drug in Parkinsons and in drug induced extra-pyramidal disorders (as caused by antipsychotics)
-alleviate tremors and rigidity
-causes mood changes, dry mouth, blurred vision, constipation, and urinary retention

-tolerance from long term use
-on-off phenomenon
-psychological disorders

what is carbidopa used in conjunction with?
it is used with levodopa, it inhibits the metabolism of levodopa in the GI tract and peripheral tissues
as OTs, what should we think about with PK pts.?
-work on gait training and balance activities
-help pt. keep function to eliminate need for more drugs
-maintain joint ROM and cardio fitness during drug holidays
Which drug for PK might a pt. take a drug holiday?
Levodopa, because tolerance can develop with long term use
bradykinesia, postural/gait abnormalities, tremors, and muscular rigidity
