Pramipexole (dopamine agonists) and Impulse-control disorder: is the FAERS signal real?
A written Bradford Hill assessment of one drug–event pair. The grade is a judgement about the signal, not a statement that this drug causes this event in any one person; FAERS counts are reports, not rates.
Pramipexole (dopamine agonists) ↔ Impulse-control disorder
n=195 co-reports · PRR 144.0 · ROR 145.8
Dopamine agonists such as pramipexole can trigger striking impulse-control disorders — pathological gambling, compulsive shopping, hypersexuality, and binge eating — by over-stimulating the brain's reward circuitry. The effect is genuine, can appear at ordinary doses, and often resolves when the drug is reduced or stopped, and it is now the subject of explicit labelling after regulatory reviews in the 2010s. The very high PRR (144.0) reflects that the term is closely tied to this drug class.
Regulatory basis: pramipexole/ropinirole prescribing information (impulse-control disorders); EMA/FDA class reviews (2010s).
| Bradford Hill viewpoint | Status | Note |
|---|---|---|
| Temporality (necessary) | met | Behaviours emerge during treatment and often resolve after dose reduction or withdrawal |
| Strength | met | Very high PRR, characteristic of dopamine agonists |
| Consistency | met | Reproduced across the class and in cohort studies |
| Specificity | met | A distinctive dopamine-agonist effect, uncommon with other drugs |
| Biological gradient | met | Broadly dose-related |
| Plausibility | met | Dopamine-receptor over-stimulation of reward pathways is the mechanism |
| Coherence | met | Coheres with the class labelling and patient warnings |
| Experiment | partial | Dechallenge (dose reduction/withdrawal) usually reverses it; no randomized trial |
| Analogy | met | Analogous to impulse-control disorders with ropinirole and other dopamine agonists |
This page's own qualitative read, not an automated/citation-gated assessment.
✗ No ClinicalTrials.gov results-posting trial in the top search hits for pramipexole captured impulse-control disorder as a coded event; the behaviour is detected through clinical interview and case series rather than a trial AE table.
