Study Notes
Pramipexole (Marapex) Overview
- Classified as an antiparkinsonian drug.
- Falls under the category of non-ergot dopamine receptor agonists.
Therapeutic Indications and Uses
- Primarily used for idiopathic Parkinson's Disease (PD); effective as monotherapy in early stages and in combination with levodopa in advanced stages.
- Significantly improves motor function in early PD and reduces motor performance fluctuations in later stages.
- Allows for a reduction in levodopa dosage when used together.
- Treats moderate to severe restless leg syndrome.
- Reduces tremors and rigidity associated with Parkinson’s disease, as well as alleviates leg restlessness.
Mechanism of Action
- Stimulates dopamine receptors in both presynaptic and postsynaptic sites within the striatum of the brain.
- Restores the balance of dopaminergic activity by binding to dopamine receptors.
Pharmacokinetics
- Metabolized hepatic (liver).
- Excreted via renal (kidney) pathways.
Adverse Effects
- Potential for amnesia, dizziness, drowsiness, hallucinations, weakness, constipation, dry mouth, dyspepsia, nausea, and orthostatic hypotension.
- Notable risk of sleep attacks that can occur unpredictably.
Contraindications and Precautions
- Contraindicated in individuals with hypersensitivity and major psychotic disorders.
- Use with caution in patients with renal, hepatic, or cardiac diseases, those taking CNS depressants, and patients with a history of psychosis, dyskinesia, or affective disorders.
Drug Interactions
- Dopamine antagonists can decrease the effectiveness of pramipexole.
- Levels may increase when taken with levodopa, cimetidine, ranitidine, diltiazem, verapamil, or quinidine.
- Kava may reduce the drug's efficacy.
Nursing Considerations and Patient Teaching
- Recommend administration with meals to reduce the risk of nausea.
- Patients should be informed of possible drowsiness and the risk of sudden sleep episodes; advise against engaging in activities requiring full alertness until they understand how the medication affects them.
- Encourage gradual position changes to help mitigate orthostatic hypotension.
