clinical history, including both pressenting symptoms and associated RFs
UPDRS-Unified PD rating scale |
|
What are the three phases of PD treatment of PD?
|
1. Lifestyle changes, nutrition, exercise

SOAP
S=sleep(Insomnia, ExcessiveDaytimeSleepiness-EDS) O=Oher miscellaneous symptoms(Nausea, fatigue, speech, dysesthesia) A=Autonomic symptoms(drooling, constipation, ED, urinary probs, OH) P-Psychological symptoms(anxiety, BPSD, OCD, Depression) |
|
What does the UPDRS measure(3)?
|
-mentation, behavior, mood

|
Gold standard for PD tx? What does long term use lead to? What doesn't it treat.
|
Levodopa.
Dyskinesias May promote oxidative stress DOes not treat: freezing, postural instability, dysautonomias, dementia, disease progression Standard vs. CR: icnrase daily dose by 20% and decrease # doses by 30-50% |
|
What drug?
DOes not cross BBB 75mg/d required to sautrate peripheral dopa decarboxylase reduce Levodopa by __% |
Carbidopa
75% |
|
What type of agents?
Class: ergot vs non-ergot like REceptor acivity: non-ergot have little/no ___ activity, alpha activity. Levodopa sparing Does not affect disease progression |
Dopamine agonists
5-HT acitivity |
|
Potent D1 and D2 agonists
Benefits total __ time in advanced PD Pre-treatment for __ required |
Apomorphine
"off" nausea |
|
ROute of admin of Apomorphine?
Dose range/frequency ADEs? |
2-6mg/inj
1-10 injections/day ADEs dyskinesias, hallucinations, OH, sedation |
|
Selegiline
-Delay need for __ __ can exert stimulatory ADEs Inhibitor of multiple ___ enzymes Doses >__mg/d lose MAO-__ selectivity)increases risk for cheese effect, not not use at this dose with levodopa) |
Levodopa
Metabolites P450 10mg/d MAO-B |
|
these drugs are adjunctive to levodopa/carbidopa
|
COMT inhibitors

Reduce l-dope dose by __% Decreased __ time |
25%
"off" |
|
For Tolcapone
-___toxicity -inhibits ___ activity Take __ hours b4 or after meal, same time qd -___ monitoring -onset of diarrhea may be delayed |
hepatotoxicity
inhibits 2C9 take 2 hours pre or post LFT monitoring |
|
Dopaminergic adverse effects of COMT inhibitors
|
Dyskinesia
N/V Hallucination Postural Hypotension or dizziness |
|
Non-dopaminergic Adverse effects of COMT inhibitors
|
Diarrhea
Abdominal pain Urine discoloration constipation Fatique LFTs elevation |
|
Useful for tremors but should be avoided in elderly
|
Anticholinergics
|
|
Indices of Toxicity
Dyskinesias Peripheral Dopaminergic:? Central Dopaminergic:? |
Peripheral: N/V, diarrhea, OH
Central dopaminergic:insomnia, somnolence, sleep attacks, hallucinations, psychosis, nightmares |
|
Treatment strategies for the most common tremorogenic drugs:
Salbutamol: Amiodarone: Amitrityline or tricyclics: Caffeine: Ciclosporin: EtOH: Li+: Metoclopramide: Neuroleptics: Nicotine: SSRIs: Tacrolimus: Valproate: |
Salbutamol: Reduce freqency or D/C; consider using longer-acting B-adrenergic agonist
Amiodarone: Screen for hyperthyroidism, reduce dose to 200mg daily; consider adding B-adrenergic antagonist Amitrityline or tricyclics: Allow time to see whether tremor will imrove, or D/c use and consider using an SSRI or B-adrenergic antagonist Caffeine: Reduce caffeine intake Ciclosporin: Avoid toxic states and consider reducing dose; try another immunosuppressive drug EtOH: Reduce intake or abstain from it Li+: Check drug concentrations and reduce dose; change drug; use B-adrenergic antagonist Metoclopramide: D/C use and monitor pt Neuroleptics: D/C or switch to a more atypical neuroleptic; add anticholinergic Nicotine: Stop using all forms of tobacco or nicotine gum SSRIs: Wait to see if tremor improves over time; reduce dose if depression allows Tacrolimus: Reduce dose Valproate: Reduce dose; switch antiepileptics |
