Pramipexole Overview and Dosage

Pramipexole Overview

• Pramipexole, also known as Mirapex, is a medication that activates dopamine receptors while mildly blocking serotonin and A-adrenergic receptors.
• Classified as a non-ergot dopamine receptor agonist, it primarily stimulates dopamine receptors to improve motor function.

Indications and Uses

• Monotherapy with pramipexole is indicated for the treatment of restless leg syndrome, aimed at improving motor performance.
• It can be used alongside levodopa to allow for lower dosing, thus helping to reduce motor control fluctuations.

Dosage Information

• Maximum oral and immediate-release dosages for treating Parkinson's disease are 1.5 mg taken three times daily (TID).
• For extended-release formulations, the maximum dosage is 4.5 mg taken four times daily (QID).

Adverse Effects

• Common adverse effects include nausea, constipation, dizziness, daytime somnolence, insomnia, sleep attacks, weakness, and hallucinations.
• When taken with levodopa, adverse effects may exacerbate, leading to increased risk of hallucination, daytime sleepiness, and postural hypotension.

Drug Interactions and Contraindications

• Pramipexole interacts with cimetidine, necessitating caution when used in combination.
• Use is contraindicated in patients with compulsive behavior and renal impairment, requiring a dosage reduction.

Patient Education

• Patients should be informed that it may take several weeks to observe the effects of pramipexole treatment, emphasizing the need for adherence to the prescribed regimen.
