Summary
Memantine and pramipexole are both cationic drugs secreted by renal tubules, so competition could modestly raise pramipexole levels. This may increase dopaminergic effects such as hallucinations, somnolence or dizziness.
What this interaction means in plain words
Memantine-donepezil and Pramipexole have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Memantine-donepezil belongs to Central Nervous System; Pramipexole belongs to Cardiovascular.
Why it happens
Competition for renal tubular cationic secretion may reduce pramipexole clearance.
What to do
No routine adjustment; monitor for confusion, hallucinations and sedation, especially in older patients.
