Parkinson disease (monotherapy or adjunctive therapy):
Immediate release: Oral:
Initial: 0.25 mg 3 times daily; may increase daily dose based on response and tolerability. For doses up to 3 mg/day, may increase daily dose by 0.75 mg every 7 days; for doses from 3 to 9 mg/day, may increase daily dose by 1.5 mg every 7 days; for doses >9 mg/day, may increase daily dose by 3 mg every 7 days.
Maximum dose: 24 mg/day in 3 divided doses (Ref).
Usual dose: 12 to 16 mg/day (Ref).
Extended release: Oral:
Initial: 2 mg once daily for 1 to 2 weeks; may increase daily dose by 2 mg at weekly or longer intervals based on response and tolerability.
Maximum dose: 24 mg/day (Ref).
Usual dose: 12 to 16 mg/day (Ref).
Converting from ropinirole immediate release to ropinirole extended release: May initiate extended release the morning after the last immediate release evening dose is taken. The total daily dose should remain the same.
Restless legs syndrome (alternative agent):
Immediate release: Oral:
Initial: 0.25 mg once daily 1 to 3 hours before bedtime. Dose may be increased after 2 days to 0.5 mg once daily, and after 7 days to 1 mg once daily. Dose may be further increased in 0.5 mg increments every week until reaching 3 mg once daily during week 6. Dose may be increased to a maximum of 4 mg/day beginning week 7 (Ref). Alternatively, some experts recommend increasing by 0.25 mg every 2 to 3 days based on response and tolerability to lowest effective dose, up to a maximum of 4 mg/day (Ref).
Note: If augmentation occurs (worsening symptoms during dopaminergic therapy), dose earlier in the evening, divide into multiple evening doses, increase dose (keeping at or below 4 mg/day), or consider switching to alternative therapy (Ref).
Discontinuation of therapy: Do not discontinue abruptly; gradually taper over 7 days. For IR formulation, some patients may tolerate a reduction in frequency of administration from 3 times daily to twice daily for 4 days, then once daily for the remaining 3 days.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Augmentation, a worsening of symptoms beyond the level of severity that was experienced when the medication was initiated, has been reported with dopamine agonists such as ropinirole, in patients with restless leg syndrome (RLS) (Ref). In addition to severity, the symptoms occur at an earlier time of day compared to pretreatment timing of symptoms (Ref). A pooled meta-analysis reported an overall augmentation rate of 5.6% in RLS with treatment (not specifically with ropinirole) (Ref). Historically, treatment with levodopa has been associated with the highest rate followed by dopamine agonists, such as ropinirole (Ref). In one study with ropinirole alone, augmentation occurred in up to 4% and was clinically meaningful in most cases (Ref).
Mechanism: Dose- and duration-related; not clearly established. Proposed mechanisms include increased dopamine concentrations in the CNS and overstimulation of the dopamine D1 receptors compared to dopamine D2 receptors in the spinal cord (Ref). Iron deficiency may also reduce the function of the dopamine transporter, increasing dopamine concentrations (Ref). In addition, augmentation may also result from dopamine receptor down-regulation, which lowers tolerance to dopaminergic effects in a circadian manner (Ref).
Onset: Delayed; usually after months of treatment (mean duration 8.8 months in one study with pramipexole) (Ref).
Risk factors:
• Higher doses (Ref)
• Longer duration of therapy (Ref)
• More severe RLS prior to treatment (may be related to higher dose use) (Ref)
• Iron deficiency (Ref)
• Older patients (Ref)
• Use of IR formulations (Ref)
Ropinirole has been associated with impulse control disorders and related disorders, manifesting as pathological gambling, increased libido (hypersexuality), compulsive or binge buying/eating, and/or other intense urges. The prevalence of impulsive control was reported to range from 2.6% to 34.8% in Parkinson disease (PD). A lower prevalence was reported in patients taking dopamine agonists, such as ropinirole, for restless leg syndrome (RLS) (Ref). Dose reduction or discontinuation of therapy has been reported to reverse these behaviors in some, but not all cases.
Mechanism: Possibly dose-related; may be due to activation of dopamine receptors (mostly D3) involved in both the nigrostriatal and the reward pathways (Ref).
Onset: Difficult to determine. In one study, the incidence of impulsive behavior was relatively low during the first 30 months of exposure but higher over the next 30 months (Ref).
Risk factors:
• Higher doses (Ref)
• Higher affinity for D3 receptors (Ref)
• Males (for PD) (Ref)
• Younger age (Ref)
• History of psychiatric symptoms (eg, anxiety and depression) (Ref)
• Family history of impulse control disorders (Ref)
• Earlier onset of PD (Ref)
• Longer duration of PD (Ref)
• Alcohol use (Ref)
Nausea and vomiting are known side effects of dopamine agonists, such as ropinirole.
Mechanism: Dose-related; may be related to direct D2 receptor agonism within the chemoreceptor trigger zone (Ref).
Onset: Commonly seen in early phase of treatment (Ref). It is important to note that reports of nausea and vomiting in studies may be subject to recall bias; so, it is unclear whether the onset of symptoms occurred with the first doses or required weeks of therapy prior to onset (Ref).
Risk factors (possible):
• Administration on an empty stomach (Ref)
• Use of IR formulations (Ref)
Ropinirole may cause orthostatic hypotension. Patients with Parkinson disease (PD) may have an impaired capacity to respond to a postural change due to neurodegenerative processes in the brain stem. Orthostatic hypotension may be asymptomatic or symptomatic, leading to dizziness and falling (Ref). Syncope, sometimes associated with bradycardia, has also been observed in association with ropinirole in early Parkinson disease patients and patients with restless leg syndrome (RLS).
Mechanism: Primarily by venous and arterial dilation through inhibition of the sympathetic nervous system (Ref).
Onset: Varied; may occur at any point during treatment (Ref). Most cases occurred more than 4 weeks after initiation and may occur more often with initiation of therapy or dose escalation.
Risk factors:
• Initiation of therapy or dose escalation
• Autonomic dysfunction (as with PD) (Ref)
• Concurrent medications that may cause orthostatic hypotension (eg, antihypertensive or antiarrhythmic medications, diuretics, levodopa, monoamine oxidase inhibitors, tricyclic antidepressants) (Ref)
• Cardiovascular disease (eg, heart failure) (Ref)
• Hypovolemia (Ref)
• Younger patients with asthenic features (Ref)
Ropinirole may cause or exacerbate behavioral changes, including psychotic symptoms (eg, paranoid ideation, hallucination, delusion, confusion, mania, disorientation, aggressive behavior, agitation, delirium). In a prospective comparison of levodopa versus ropinirole treatment, ropinirole demonstrated a higher incidence of hallucinations compared to levodopa (17% vs 6%) (Ref).
Mechanism: Dose- and duration-related; ropinirole is a non-ergot D2/D3 dopamine agonist with greatest affinity for D3 receptors. Psychosis is thought to result from some degree of D2 receptor stimulation (Ref).
Onset: Hallucinations typically occurred more frequently in adjunct studies versus early therapy studies for Parkinson disease (Ref).
Risk factors:
• Higher doses (Ref)
• Longer duration of therapy (Ref)
• Comorbid cognitive impairment or dementia (Ref)
• Older patients (hallucinations)
• Previous history of hallucinations (Ref)
• Number of comorbidities and concurrent medications (Ref)
Somnolence (drowsiness) is an adverse reaction of dopamine agonists, including ropinirole (Ref). Patients taking ropinirole may experience sleep attacks (sudden onset of sleep), defined as sudden, irresistible, overwhelming sleepiness without awareness of falling sleep (Ref). Conversely, studies in patients with restless leg syndrome (RLS) found that ropinirole may improve sleep adequacy, quantity, and sleep disturbance, and reduce daytime somnolence (Ref). Sleep attacks may also occur in patients with Parkinson disease (PD) in the absence of dopaminergic medications (Ref).
Mechanism: Likely multifactorial; related to modulation of dopamine receptors, specifically D3 agonist activity. May also be the result of increased dopamine, leading to down regulation of dopaminergic input to the reticular activating system. Genetic polymorphisms in dopamine receptors may play a role (Ref).
Onset: Delayed; some cases have occurred more than a year after initiation.
Risk factors:
• Longer treatment duration (Ref)
• Patients with PD (Ref)
• Depression in patients with PD (Ref)
• Disease duration <7 years (Ref)
• Age <70 years (Ref)
• History of sleep disorders (other than RLS)
• Concurrent alcohol or medications that may cause sedation or increase ropinirole plasma levels
Dopamine agonist withdrawal syndrome (DAWS) has been defined as a stereotyped cluster of physical and psychological symptoms that may be mild, moderate, or severe. Psychiatric symptoms may include anxiety, panic attacks, depression, irritability, agitation, dysphoria, agoraphobia, insomnia, drug cravings, and pain. Physical symptoms may include diaphoresis, flushing, nausea, fatigue, orthostatic hypotension, and vomiting. Psychiatric symptoms are the most common and prominent symptoms (Ref). DAWS has been reported mainly in Parkinson disease, where it affects about 15% to 19% of patients who taper or discontinue a dopamine agonist (Yu 2017). Some recent case reports have identified this syndrome in patients with restless leg syndrome as well (Ref). Symptoms may be self-limited or protracted, lasting for months to years (Yu 2017).
Mechanism: Exact mechanism unknown; may be dose- and duration-related. May be due to sudden changes in dopaminergic stimulation (Ref).
Onset: Varied; may occur at any time during taper or after discontinuation (Ref).
Risk factors:
• Higher daily doses (≥7.5 mg/day) (Ref)
• Cumulative exposure to dopamine agonists (Ref)
• Presence of impulse control disorder (Ref)
• History of deep brain stimulation (Ref)

Postmarketing (all indications and formulation):
Cardiovascular: Heart valve disease (Andersohn 2009, Dewey 2007)
Nervous system: Aggressive behavior, agitation, behavioral problems, delirium, delusion, disorientation, falling (Kujawa 2000), impulse control disorder (including increased libido, pathological gambling) (Bastiaens 2013; Corvol 2018), mania, paranoid ideation, psychotic symptoms (Grover 2010), restless legs syndrome (IR: RLS: augmentation and/or early morning rebound) (García-Borreguero 2012, Rosenstein 2015), withdrawal syndrome (including anxiety, apathy, depression, insomnia) (Yu 2017)
Respiratory: Interstitial pulmonary disease, pleuropulmonary fibrosis (Andersohn 2009)
Hypersensitivity (eg, urticaria, angioedema, rash, pruritus) to ropinirole or any component of the formulation
Concerns related to adverse effects:
• Dyskinesias: May cause and/or exacerbate dyskinesias. Use with caution in patients with preexisting dyskinesias. Decreasing the dose may alleviate this condition.
• Pleural/retroperitoneal fibrosis: Ergot-derived dopamine agonists have been associated with fibrotic complications (eg, pericarditis, retroperitoneal fibrosis, pleural effusion, pleural thickening, pulmonary infiltrates, cardiac valvulopathy). Although ropinirole is not an ergot, there have been postmarketing reports of possible fibrotic complications (pleural effusion, pleural fibrosis, interstitial lung disease, and cardiac valvulopathy) with ropinirole; monitor closely for signs and symptoms of fibrosis. Discontinuation of therapy may resolve complications, but not in all cases.
• Retinal changes: Pathologic degenerative changes were observed in the retinas of albino rats during studies with this agent, but were not observed in the retinas of albino mice or in other species. The significance of these data for humans remains uncertain.
Disease-related concerns:
• Cardiovascular disease: Use with caution in patients with cardiovascular disease because of a risk for elevation in BP and changes in heart rate.
• Hepatic impairment: Use with caution in patients with hepatic impairment (extensively metabolized).
• Psychotic disorder: Avoid use in patients with a major psychotic disorder; may exacerbate symptoms.
• Renal impairment: Use with caution in patients with severe kidney impairment.
Dosage form specific issues:
• Extended release: ER ropinirole is designed to release medication over a 24-hour period. If rapid GI transit occurs, there may be risk of incomplete release of medication and medication residue being passed in the stool.

Information related to the use of ropinirole for the treatment of restless legs syndrome in pregnant women is limited. Current guidelines note that the available information is insufficient to make a recommendation for use in pregnant women (Aurora 2012; Dostal 2013; Tüfekçioğlu 2018).
It is not known if ropinirole is present in breast milk.
Ropinirole inhibits prolactin secretion in humans and may potentially inhibit lactation. According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother.
BP (orthostatic); signs and symptoms of postural hypotension, especially during dose escalation (Parkinson patients); daytime alertness; CNS depression, fall risk, behavior changes (eg, compulsive behaviors); periodic skin examinations
Ropinirole has a high relative in vitro specificity and full intrinsic activity at the D2 and D3 dopamine receptor subtypes, binding with higher affinity to D3 than to D2 or D4 receptor subtypes; relevance of D3 receptor binding in Parkinson disease is unknown. Ropinirole has moderate in vitro affinity for opioid receptors. Ropinirole and its metabolites have negligible in vitro affinity for dopamine D1, 5-HT1, 5-HT2, benzodiazepine, GABA, muscarinic, alpha1-, alpha2-, and beta-adrenoreceptors. Although precise mechanism of action of ropinirole is unknown, it is believed to be due to stimulation of postsynaptic dopamine D2-type receptors within the caudate putamen in the brain. Ropinirole caused decreases in systolic and diastolic blood pressure at doses >0.25 mg. The mechanism of ropinirole-induced postural hypotension is believed to be due to D2-mediated blunting of the noradrenergic response to standing and subsequent decrease in peripheral vascular resistance.
Absorption: Immediate release: Rapid
Distribution: Vd: 7.5 L/kg
Protein binding: 40%
Metabolism: Extensively hepatic via CYP1A2 to inactive metabolites; first-pass effect
Bioavailability: Absolute: 45% to 55%
Half-life elimination: ~6 hours
Time to peak: Immediate release: ~1-2 hours; Extended release: 6-10 hours; Tmax increased by 2.5-3 hours when taken with a high-fat meal
Excretion: Urine (<10% as unchanged drug, 60% as metabolites)
Altered kidney function: Clearance of ropinirole was reduced by ~30% in patients with ESRD on dialysis
Hepatic function impairment: Patients with hepatic impairment may have higher plasma levels and lower clearance of ropinirole
Older adult: Oral clearance is reduced ~15% in patients >65 years
Cigarette smoking: Clearance is expected to increase because CYP1A2 is known to be induced by smoking. Cmax was 30% and AUC was 38% lower in smokers compared with nonsmokers.
