Study Notes

Nonpharmacologic therapy for Parkinson's Disease (PD) includes good nutrition, physical activity, and social interactions, which improve activities of daily living (ADLs), gait, balance, and mental health.
Pharmacologic therapy for motor symptoms aims to enhance dopaminergic activity in the substantia nigra.
Choice of pharmacologic agent depends on patient-specific parameters and dosage regimens.
treatment recommendations: AAN and MDS suggest levodopa/carbidopa or a dopamine agonist, while NICE recommends levodopa/carbidopa - once motor symptoms appear.
Treatment includes initiation with gradual dosage titration, maintaining therapy at lowest effective dosage, and discontinuing therapy with gradual tapering if necessary.
Drugs for PD:
- Drugs that affect brain dopaminergic system: dopaminergic agonists (bromocriptine, pergolide), dopamine precursor (levodopa), peripheral decarboxylase inhibitors (carbidopa, benserazide), MAO-B inhibitor (selegiline, rasagiline), and COMT inhibitors (entacapone, tolcapone).
- Drugs that affect brain cholinergic system: central anticholinergics (procyclidine) and antihistaminics (orphenadrine, promethazine).
Drug choice is based on clinical experience and patient preference.
PD medication discontinuation is gradual and monitored for worsening motor symptoms.
Starting with a dopamine agonist may delay the onset of dyskinesias but has less motor benefit and a greater risk of hallucinations or somnolence.
Levodopa provides the greatest motor improvement but has adverse effects: GIT (anorexia, nausea, and vomiting), CVS (orthostatic hypotension and cardiac arrhythmias), and centrally mediated adverse effects (dyskinesias and serious mental disturbances).
Anticholinergics minimize resting tremor and drooling but are not as effective as other agents for rigidity, bradykinesia, and gait problems.
Amantadine is effective as monotherapy and adjunct therapy for off time and dyskinesia.
MAO-B inhibitors (safinamide, selegiline, and rasagiline) provide a mild symptomatic benefit and help delay dopaminergic medications.
MAO-B inhibitors have adverse effects: nausea, confusion, hallucinations, jitteriness, insomnia, and orthostatic hypotension.
Dopamine agonists delay levodopa therapy and have smaller risks of motor fluctuations during the first 4 to 5 years of treatment.
Rotigotine patch minimizes pulsatile stimulation of dopamine and has common side effects: nausea, vomiting, sedation, orthostatic hypotension, and uncommon ergot side effects.
Istradefylline, the first adenosine A2A receptor antagonist, is US-FDA approved for treating off episodes in PD.
Specialist care for PD patients includes: dentist, dietician, speech therapist, physical therapist, occupational therapist, and social worker.
