Study Notes
Parkinson's Disease and Neurotransmitters
- Dopamine is the key inhibitory neurotransmitter involved in Parkinson's disease, linked to its low concentrations in affected individuals.
- Acetylcholine serves as an excitatory neurotransmitter that counters dopamine.
Medication Dosage Calculation
- Entacapone dosage of 400 mg every 6 hours equals a total of 1600 mg in a 24-hour period (400 mg x 4 doses).
Adverse Effects of Amantadine
- Dizziness is a common adverse effect associated with amantadine, necessitating caution when changing positions to prevent sudden blood pressure drops.
Amantadine Syrup Administration
- For an ordered dose of 100 mg of amantadine and a concentration of 10 mg/mL, the nurse administers 10 mL of syrup (100 mg / 10 mg/mL).
"On-off" Phenomenon in Levodopa/Carbidopa Treatment
- Recurrence of symptoms in patients on levodopa/carbidopa indicates the 'on-off' phenomenon, where adjustments to the medication regimen may lessen these episodes.
MAOIs and Carbidopa-Levodopa Synonymy
- Monoamine oxidase inhibitors (MAOIs) are prescribed alongside carbidopa-levodopa to enhance efficacy, particularly when patients become insensitive to treatment over time.
Selegiline Administration Protocol
- The correct administration order for selegiline [Eldepryl] involves a dosage of 5 mg twice daily, which is appropriate for treating depression in Parkinson's disease patients.
