Health Canada's review of the available information has established a link between use of the dopamine agonists pramipexole, quinagolide, or ropinirole and the risk of dopamine agonist withdrawal syndrome (DAWS). DAWS may occur after reducing the dose of or discontinuing dopamine agonists, and includes symptoms such as apathy, anxiety, depression, fatigue, sweating, panic attacks, insomnia, irritability, and pain. The Canadian product information for pramipexole has been updated to include a warning on the risk of DAWS. Health Canada will work with the manufacturers of quinagolide and ropinirole to update the product information to include a warning on the risk of DAWS. At this time, there is not enough information to establish a link between other dopamine agonists that were assessed as part of this safety review (ie, apomorphine, bromocriptine, cabergoline, pergolide [no longer marketed], and rotigotine) and DAWS. As a precaution, Health Canada will work with the manufacturers of these dopamine agonists to include the potential risk of DAWS in the product information.

Parkinson disease:
Early-stage: Transdermal: Initial: Apply 2 mg/24 hours patch once daily; may increase daily dose by 2 mg/24 hours weekly based on clinical response and tolerability. Maximum: 6 mg/24 hours according to the prescribing information; higher doses (eg, 8 mg/24 hours) have been studied in clinical trials (Giladi 2007).
Advanced-stage: Transdermal: Initial: Apply 4 mg/24 hours patch once daily; may increase daily dose by 2 mg/24 hours weekly based on clinical response and tolerability. Maximum: 8 mg/24 hours; higher doses (eg, 12 to 16 mg/24 hours) have been studied in clinical trials (LeWitt 2007; Poewe 2007).
Discontinuation of treatment in Parkinson disease: Do not discontinue abruptly; decrease daily dose by ≤2 mg/24 hours preferably every other day until withdrawal complete.
Restless legs syndrome (alternative agent):
Initial: Transdermal: Apply 1 mg/24 hours patch once daily; may increase daily dose by 1 mg/24 hours weekly, based on clinical response and tolerability to a maximum of 3 mg/24 hours (AAN [Winkelman 2016]; manufacturer's labeling).
Note: If augmentation occurs (worsening symptoms during dopaminergic therapy), consider increasing dose (keeping at or below 3 mg/24 hours) or switching to alternative therapy (IRLSSG/EURLSSG/RLS-F [Garcia-Borreguero 2016]).

Concerns related to adverse effects:
• Application site reactions: Dose-dependent application site reactions, potentially severe, have been observed; daily rotation of application sites has been shown to decrease incidence of reactions. If a generalized (nonapplication site) skin reaction occurs; discontinue therapy.
• Fibrosis: Rare cases of pleural effusion, pleural thickening, pulmonary infiltrates, retroperitoneal fibrosis, pericarditis and/or cardiac valvulopathy have been reported in patients treated with ergot-derived dopamine agonists. The potential of rotigotine, a non–ergot-derived dopamine agonist, to cause similar fibrotic complications is unknown. Discontinuation of therapy may resolve complications, but not in all cases.
• Fluid retention: Weight gain and fluid retention have been reported, primarily associated with development of peripheral edema in Parkinson disease patients; use caution and monitor in patients with concomitant illnesses (eg, heart failure or renal insufficiency).
• Hallucinations/psychotic-like behavior: May cause hallucinations (dose-related) and other psychotic-like behaviors (eg, agitation, delirium, delusions, aggression). In general, avoid use in patients with preexisting major psychotic disorders.
• Impulse control disorders: Dopamine agonists used for Parkinson disease or restless legs syndrome have been associated with compulsive behaviors and/or loss of impulse control, which has manifested as pathological gambling, libido increases (hypersexuality), and/or binge eating. Causality has not been established, and controversy exists as to whether this phenomenon is related to the underlying disease, prior behaviors/addictions and/or drug therapy. Dose reduction or discontinuation of therapy has been reported to reverse these behaviors in some, but not all cases.
• Orthostatic hypotension: Dopamine agonists may cause orthostatic hypotension and syncope; Parkinson disease patients appear to have an impaired capacity to respond to a postural challenge. Use with caution in patients at risk of hypotension (such as those receiving antihypertensive drugs) or where transient hypotensive episodes would be poorly tolerated (cardiovascular disease or cerebrovascular disease). Monitor for postural hypotension, especially during dose escalation.
• Somnolence: Use is commonly associated with somnolence. In addition, falling asleep during activities of daily living, including while driving, has also been reported and may occur without significant warning signs. Monitor for daytime somnolence or pre-existing sleep disorder. Patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Use with caution in patients receiving other CNS depressants or psychoactive agents; discontinue if significant daytime sleepiness or episodes of falling asleep occur. Effects with other sedative drugs or ethanol may be potentiated.
Disease-related concerns:
• Cardiovascular disease: Use with caution in patients with pre-existing cardiovascular disease; therapy has been associated with increases in blood pressure (as well as orthostatic hypotension), which may be significant (>40 mm Hg or ≥20 mm Hg increase in systolic or diastolic measurements, respectively), increased heart rate, syncope, and weight gain/fluid retention.
• Dyskinesia: Use with caution in patients with preexisting dyskinesia; therapy may cause or exacerbate dyskinesia.
Special populations:
• Restless legs syndrome: Augmentation (earlier onset of symptoms each day and/or worsening symptoms during dopaminergic therapy) may occur in some restless leg syndrome (RLS) patients. Risk factors for dopaminergic-induced augmentation include higher doses of dopaminergic agents, use of shorter-acting dopamine agonists (ie, pramipexole, ropinirole) or levodopa, low iron stores, and increased severity of symptoms prior to treatment initiation. To minimize risk of augmentation, use the lowest effective dose and avoid exceeding recommended doses. Patients may also be switched to alternative therapy if augmentation occurs (Garcia-Borreguero 2016). End-of-dose rebound (reappearance of symptoms in the early morning hours) may also occur. Consider dosage adjustment or discontinuation of treatment if rebound symptoms occur.
Dosage form specific issues:
• Aluminum: Patch contains aluminum; remove patch prior to magnetic resonance imaging or cardioversion to avoid skin burns.
• Heat application: Avoid exposure of application site to any direct external heat sources (eg, hair dryers, heating pads, electric blankets, saunas, hot tubs, direct sunlight); heat exposure has not been studied with the rotigotine patch, but an increase in the rate and extent of absorption has been observed with other transdermal products.
• Sulfites: Patch contains sodium metabisulfite which may cause allergic reaction in susceptible individuals.
Other warnings/precautions:
• Discontinuation of therapy: Taper treatment when discontinuing therapy; do not stop abruptly. Other dopaminergic agents have been associated with a syndrome resembling neuroleptic malignant syndrome on withdrawal and/or significant dosage reduction. Apathy, anxiety, depression, fatigue, insomnia, pain, and sweating have occurred during taper or after discontinuation of therapy, which may not respond well to levodopa. Educate patient on potential of withdrawal symptoms; consider readministration of a dopamine agonist at the lowest effective dose in patients experiencing symptoms.

Information related to the use of rotigotine in pregnancy is limited (Dostal 2013).
Available guidelines note there is insufficient evidence to recommend rotigotine for use in pregnant females with restless leg syndrome (Picchietti 2015) or Parkinson disease (Seier 2017)
It is not known if rotigotine is present in breast milk.
Rotigotine decreases prolactin secretion and lactation may be inhibited.
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.
Blood pressure (including orthostatic); daytime alertness; weight gain in patients at risk for fluid retention (eg, heart failure, renal insufficiency).
Rotigotine is a nonergot dopamine agonist with specificity for D3-, D2-, and D1-dopamine receptors. Although the precise mechanism of action of rotigotine is unknown, it is believed to be due to stimulation of postsynaptic dopamine D2-type auto receptors within the substantia nigra in the brain, leading to improved dopaminergic transmission in the motor areas of the basal ganglia, notably the caudate nucleus/putamen regions.
Distribution: Vd: ~84 L/kg.
Protein binding: ~90%.
Metabolism: Extensive via conjugation and N-dealkylation; multiple CYP isoenzymes, sulfotransferases, and two UDP-glucuronosyltransferases involved in catalyzing the metabolism.
Half-life elimination: After removal of patch: 5 to 7 hours.
Time to peak, plasma: 15 to 18 hours; can occur 4 to 27 hours post application.
Excretion: Urine (~71% as inactive conjugates and metabolites, <1% as unchanged drug); feces (~23%).
Renal function impairment: In subjects with severe renal impairment not on dialysis (eg, CrCl 15 to <30 mL/minute), exposure to conjugated rotigotine metabolites was doubled.
Geriatric: Although not studied, exposures in older subjects (older than 80 years of age) may be higher because of skin changes with aging.
