ropinirole at a glance
Medicine class
Non-ergoline dopamine agonist acting mainly at D2 and D3 receptors.
Licensed use
Parkinson’s disease, alone or with levodopa.
Prolonged-release tablets
Swallow whole; do not crush, chew or divide.
Driving and machinery
Can cause marked sleepiness or sudden sleep without warning.
What is ropinirole used for?
The selected prolonged-release product is licensed for Parkinson’s disease in adults.
It may be used alone before levodopa is introduced.
It may be added to levodopa when benefit wears off or fluctuates.
How does ropinirole work?
Ropinirole stimulates D2 and D3 dopamine receptors in the striatum. This partly substitutes for reduced dopamine signalling in Parkinson’s disease and can improve stiffness, slowness and tremor; it does not cure the condition.
How to take ropinirole
Follow the dispensing label and take the prescribed formulation consistently. Prolonged-release tablets may be taken with or without food, but a high-fat meal can increase ropinirole exposure.
Swallow prolonged-release tablets whole with water.
Do not crush, chew or divide them.
Do not stop ropinirole abruptly.

ropinirole in pregnancy
Ropinirole is not usually recommended during pregnancy because human safety information is limited. It should be considered only after specialist assessment concludes that expected benefit outweighs potential fetal risk. Contact the prescriber promptly if pregnancy occurs.
ropinirole while breastfeeding
The selected product information advises against use while breastfeeding because transfer into human milk is unknown, infant risk cannot be excluded and ropinirole may suppress milk production.
ropinirole interactions
Check prescribed, pharmacy and complementary medicines with a pharmacist or prescriber. Important examples include:
Metoclopramide, sulpiride and other dopamine antagonists
They may oppose ropinirole’s dopamine effect and reduce symptom control.
Ciprofloxacin, fluvoxamine and other CYP1A2 inhibitors
They can increase ropinirole exposure and the likelihood of adverse effects.
High-dose oestrogens, including some HRT
Starting or stopping treatment can alter ropinirole concentrations and may require clinical review.
