Ropark on suun kautta otettava ropinirole (0.25 / 0.5 / 1 / 2 mg) tablet — a non-ergot dopamine agonist jota käytetään Parkinsonin tauti ja moderate-to-severe restless legs syndrome (RLS). It directly stimulates dopamine D2/D3 receptors in the brain, partially substituting for the dopamine that is no longer being made. Compared with pramipexole, ropinirole has higher CYP1A2 dependence (avoid with ciprofloxacin and fluvoxamine; smoking lowers levels). Compared with bromocriptine, it does ei cause cardiac valve fibrosis. Critical safety signals: impulssikontrollihäiriöille (gambling, hypersexuality, binge eating, compulsive shopping), sudden-onset sleep (sleep attacks while driving), and orthostatic hypotension. Dose must be titrated up slowly and tapered down slowly — never stopped abruptly.

What Is Ropark?
Ropark is an oral tablet containing ropinirole 0.25 / 0.5 / 1 / 2 mg. ropinirole is a non-ergot dopamine D2/D3 receptor agonist, originally introduced as Requip. Ropark is manufactured by a WHO-GMP certified facility and is bioequivalent to the originator brand at the same strength.
Ropinirole is one of the two most widely used non-ergot dopamine agonists (the other is pramipexole). It is suitable as monotherapy in early Parkinson disease — particularly in younger patients where delaying levodopa is desirable to delay levodopa-induced dyskinesia — and as adjunct in advanced disease. It also has a separate licence for moderate-to-severe restless legs syndrome (RLS).
How Does Ropark (ropinirole) Work?
Ropinirole directly stimulates dopamine D2 and D3 receptors (with the highest selectivity for D3) in the striatum and limbic system, partially substituting for missing dopamine in Parkinson disease. The high D3 selectivity is also responsible for the strong effect on restless legs syndrome. It does not affect serotonin 5-HT2B receptors, so unlike ergot agonists it does not cause cardiac valve fibrosis.
Who Is Ropark For?
Ropark is appropriate for adults with Parkinson disease (monotherapy in early disease, adjunct to levodopa in advanced disease) and for moderate-to-severe restless legs syndrome unresponsive to non-pharmacological measures and iron repletion. Younger Parkinson patients (under 65) often benefit most from starting with a dopamine agonist before levodopa, to delay onset of levodopa-induced dyskinesia.
Annostelu ja titraus
Dopamine agonist therapy must be titrated upwards over weeks to avoid intolerable nausea, postural hypotension and somnolence. The dose schedule below is a typical starting framework — your neurologist will tailor it to your response.
| Viikko | Dose for Parkinson disease | Dose for RLS |
|---|---|---|
| 1 | 0.25 mg three times daily (0.75 mg/day) | 0.25 mg once at bedtime |
| 2 | 0.5 mg three times daily (1.5 mg/day) | 0.5 mg once at bedtime |
| 3 | 0.75 mg three times daily (2.25 mg/day) | 1 mg once at bedtime |
| 4 | 1 mg three times daily (3 mg/day) | 2 mg once at bedtime |
| Ylläpito | 3–9 mg/day in 3 divided doses (max 24 mg/day) | 2–4 mg at bedtime; max 4 mg/day for RLS |
Ropinirole is also available in a once-daily prolonged-release (XL/Modutab) formulation for Parkinson disease, allowing single-dose administration of up to 24 mg/day. This Ropark presentation is the immediate-release tablet, taken three times daily for Parkinson disease or once at bedtime for restless legs.
Yleisimmät haittavaikutukset
Yleisiä (>10%): nausea, dizziness, somnolence, postural hypotension, peripheral oedema (ankle swelling), constipation, hallucinations (visual more than auditory), dyskinesia (when combined with levodopa).
Vähemmän yleisiä mutta vakavia: sudden-onset sleep, impulse-control disorders, livedo reticularis (mottled skin pattern), vivid dreams, leg oedema, syncope, dyskinesia, hallucinations, paranoia.
Harvinainen: dopamine agonist withdrawal syndrome (DAWS) on rapid taper — depression, anxiety, panic, fatigue, drug craving, autonomic instability. This is the reason agonists must be tapered slowly.
Lääkeaineenvaihdunta
- Dopamiinivastustajat — metoclopramide, prochlorperazine, haloperidol, risperidone, olanzapine: pharmacological antagonism, may worsen Parkinson symptoms. Use domperidone or ondansetron for nausea instead.
- Keskushermostoa lamaavat aineet — alcohol, benzodiazepines, opioids, sedating antihistamines: increased somnolence and sleep-attack risk.
- Verenpainelääkkeet — additive postural hypotension. Stand up slowly. Monitor blood pressure during titration.
- Levodopa — intentional combination, but may unmask dyskinesia. Lower the levodopa dose if dyskinesia emerges.
- CYP1A2:n estäjät — ciprofloxacin and fluvoxamine markedly raise ropinirole levels — reduce dose. Smoking induces CYP1A2 and lowers levels; if you stop smoking, levels rise and dose may need reduction.
Usein Kysytyt Kysymykset
Can I use Ropark as my only Parkinson medication?
Yes — especially in early Parkinson disease. Many neurologists start patients under 65–70 on a dopamine agonist alone, adding levodopa later when symptoms outgrow agonist therapy. This strategy delays levodopa-induced dyskinesia by years.
Why does the dose go up so slowly?
Dopamine receptors take days to weeks to adapt. Starting at full dose causes severe nausea, vomiting, dizziness and postural drops. Slow titration lets the brain and gut adjust. Skipping the titration schedule almost always results in stopping the drug because side effects feel intolerable.
Can I stop Ropark abruptly if I dislike it?
No. Sudden withdrawal causes dopamine agonist withdrawal syndrome: depression, anxiety, panic, drug craving and autonomic instability. Even short courses should be tapered over 7–14 days, and longer courses over weeks. Always do this with your neurologist.
What about gambling and other compulsive behaviours?
Approximately 1 in 6 patients on a dopamine agonist develops a new compulsive behaviour — gambling, online shopping, hypersexuality, binge eating. The patient often does not recognise it. Tell a partner or family member to watch for changes. If they appear, contact your neurologist promptly. The behaviour usually reverses with dose reduction.
Is Ropark safe to use long-term?
Yes, with monitoring. Long-term concerns are impulse-control disorders, peripheral oedema, daytime somnolence, and (rarely) hallucinations or psychosis — all manageable with dose adjustment. Unlike ergot agonists (e.g. bromocriptine, pergolide, cabergoline), non-ergot agonists do not cause cardiac valve fibrosis.
Will Ropark cause restless legs syndrome to come back?
Ropark is also licensed for restless legs syndrome at lower doses (0.25–4 mg at bedtime). Long-term use of dopamine agonists for RLS can cause augmentation — symptoms come on earlier in the day, become more intense, and spread to other body parts. If augmentation occurs, switch off the agonist (under specialist guidance) to a non-dopaminergic option such as gabapentin enacarbil or pregabalin.
Can I drink alcohol on Ropark?
Avoid heavy or regular drinking. Alcohol increases somnolence, sleep-attack risk, postural hypotension and the chance of unmasking impulse-control behaviour. An occasional drink with food is usually acceptable; ask your neurologist for individualised advice.
Can I drive while taking Ropark?
Not until you have been on a stable dose for at least 2 weeks ja have not experienced any sleep attacks or excessive daytime sleepiness. Even then, if you ever fall asleep without warning, stop driving and tell your neurologist.
Mitä teen, jos unohdan ottaa annoksen?
Take it as soon as you remember unless it is close to the next scheduled dose. Do not double up. If you miss several doses in a row, contact your neurologist — you may need to re-titrate from a lower dose to avoid first-dose nausea.
Can Ropark cause swelling of the legs?
Yes. Peripheral oedema (ankle swelling) affects 5–15% of users and is more common in older patients and at higher doses. It is dose-related and usually improves on dose reduction. Diuretics are ei very effective; the better fix is reducing or rotating the agonist.
