1 INDICATIONS AND USAGE Ropinirole extended-release tablets are indicated for the treatment of Parkinson’s disease. Ropinirole extended-release tablets are a non-ergoline dopamine agonist indicated for the treatment of Parkinson’s disease. ( 1 )

2 DOSAGE AND ADMINISTRATION Ropinirole extended-release tablets are taken once daily, with or without food; tablets must be swallowed whole and not be chewed, crushed, or divided. ( 2.1 ) The recommended starting dose is 2 mg taken once daily for 1 to 2 weeks; the dose should be increased by 2 mg/day at 1 week or longer intervals. The maximum recommended dose of ropinirole extended-release tablets is 24 mg/day. ( 2.2 , 14.2 ) Renal Impairment: In patients with end-stage renal disease on hemodialysis, the maximum recommended dose is 18 mg/day. ( 2.2 ) If ropinirole extended-release tablets must be discontinued, it should be tapered gradually over a 7-day period; retitration of ropinirole extended-release tablets may be warranted if therapy is interrupted. ( 2.1 , 2.2 ) Patients may be switched directly from immediate-release ropinirole to ropinirole extended-release tablets; the initial switching dose of ropinirole extended-release tablets should approximately match the total daily dose of immediate-release ropinirole. ( 2.3 ) 2.1 General Dosing Recommendations Ropinirole extended-release tablets are taken once daily, with or without food [see Clinical Pharmacology (12.3) ]. Tablets must be swallowed whole and must not be chewed, crushed, or divided. If a significant interruption in therapy with ropinirole extended-release tablets has occurred, retitration of therapy may be warranted. 2.2 Dosing for Parkinson’s Disease The recommended starting dose of ropinirole extended-release tablets is 2 mg taken once daily for 1 to 2 weeks, followed by increases of 2 mg/day at weekly or longer intervals, based on therapeutic response and tolerability. Monitor patients at least weekly during dose titration. Too rapid a rate of titration may lead to the selection of a dose that does not provide additional benefit, but increases the risk of adverse reactions. In fixed-dose studies designed to characterize the dose response to ropinirole extended-release tablets, there was no additional therapeutic benefit shown in patients with advanced stage Parkinson’s disease taking daily doses greater than 8 mg/day, or with early stage Parkinson’s disease taking doses greater than 12 mg/day [see Clinical Studies ( 14.1 and 14.2 )] . Although the maximum recommended dose of ropinirole extended-release tablets is 24 mg, patients with advanced Parkinson’s disease should generally be maintained at daily doses of 8 mg or lower and patients with early Parkinson’s disease should generally be maintained at daily doses 12 mg or lower. Ropinirole extended-release tablets should be discontinued gradually over a 7-day period [see Warnings and Precautions ( 5.9 )] . Renal Impairment No dose adjustment is necessary in patients with moderate renal impairment (creatinine clearance of 30 to 50 mL/min). The recommended initial dose of ropinirole extended-release tablets for patients with end-stage renal disease on hemodialysis is 2 mg once daily. Further dose escalations should be based on tolerability and need for efficacy. The recommended maximum total daily dose is 18 mg/day in patients receiving regular dialysis. Supplemental doses after dialysis are not required. The use of ropinirole extended-release tablets in patients with severe renal impairment without regular dialysis has not been studied. 2.3 Switching from Immediate-Release Ropinirole Tablets to Ropinirole Extended-Release Tablets Patients may be switched directly from immediate-release ropinirole tablets to ropinirole extended-release tablets. The initial dose of ropinirole extended-release tablets should approximately match the total daily dose of the immediate-release formulation of ropinirole, as shown in Table 1. Table 1. Conversion from Immediate-Release Ropinirole Tablets to Ropinirole Extended-Release Tablets Immediate-Release Ropinirole Tablets Ropinirole Extended-Release Tablets Total Daily Dose (mg) Total Daily Dose (mg) 0.75 to 2.25 2 3 to 4.5 4 6 6 7.5 to 9 8 12 12 15 16 18 18 21 20 24 24 Following conversion to ropinirole extended-release tablets, the dose may be adjusted depending on therapeutic response and tolerability [see Dosage and Administration (2.2) ]. 2.4 Effect of Gastrointestinal Transit Time on Medication Release Ropinirole extended-release tablets are designed to release medication over a 24-hour period. If rapid gastrointestinal transit occurs, there may be risk of incomplete release of medication and medication residue being passed in the stool.

6 ADVERSE REACTIONS The following adverse reactions are described in more detail in other sections of the label: Hypersensitivity [see Contraindications (4) ] Falling asleep during activities of daily living and somnolence [see Warnings and Precautions (5.1) ] Syncope [see Warnings and Precautions (5.2) ] Hypotension/orthostatic hypotension [see Warnings and Precautions (5.3) ] Elevation of blood pressure and changes in heart rate [see Warnings and Precautions (5.4) ] Hallucinations/psychotic-like behavior [see Warnings and Precautions (5.5) ] Dyskinesia [see Warnings and Precautions (5.6) ] Impulse control/compulsive behaviors [see Warnings and Precautions (5.7) ] Withdrawal-emergent hyperpyrexia and confusion [see Warnings and Precautions (5.8) ] Withdrawal symptoms [see Warnings and Precautions (5.9) ] Fibrotic complications [see Warnings and Precautions (5.10) ] Retinal pathology [see Warnings and Precautions (5.11) ] Most common adverse reactions (incidence for ropinirole extended-release tablets all doses at least 5% greater than placebo in either a flexible- or fixed-dose study) in patients with advanced Parkinson’s disease were nausea, dyskinesia, dizziness, and hallucination. ( 6.1 ) Most common adverse reactions (incidence for ropinirole extended-release tablets all doses at least 5% greater than placebo in fixed-dose study) in patients with early Parkinson’s disease not taking L-dopa were nausea, somnolence, sudden onset of sleep, hypertension, and headache. In a flexible-dose study in patients with early Parkinson's, the most common adverse reactions (at least 5% incidence for ropinirole extended-release tablets) were nausea, somnolence, abdominal pain/discomfort, dizziness, headache, and constipation.

During the premarketing development of ropinirole extended-release tablets, patients with advanced Parkinson’s disease received ropinirole extended-release tablets or placebo as adjunctive therapy with L-dopa in a flexible-dose clinical trial. In a flexible-dose trial, patients with early Parkinson’s disease were treated with ropinirole extended-release tablets or the immediate-release formulation of ropinirole without L-dopa. In addition, placebo-controlled, fixed-dose, postmarketing trials evaluated the dose response of ropinirole extended-release tablets in patients with advanced Parkinson’s disease taking L-dopa and in patients with early Parkinson’s disease without concomitant L-dopa. Advanced Parkinson’s Disease (with L-dopa) Study 1 was a 24-week, double-blind, placebo-controlled, flexible-dose trial in patients with advanced Parkinson’s disease. In Study 1, the most commonly observed adverse reactions in patients treated with ropinirole extended-release tablets (incidence at least 5% greater than placebo) were dyskinesia, nausea, dizziness, and hallucinations. In Study 1, approximately 6% of patients treated with ropinirole extended-release tablets discontinued treatment due to adverse reactions, compared with 5% of patients who received placebo. The most common adverse reaction in patients treated with ropinirole extended-release tablets causing discontinuation of treatment with ropinirole extended-release tablets in Study 1 was hallucination (2%). Table 2 lists adverse reactions that occurred in at least 2% (and were numerically greater than placebo) of patients with advanced Parkinson’s disease treated with ropinirole extended-release tablets who participated in Study 1. In this trial, either ropinirole extended-release tablets or placebo was used as an adjunct to L-dopa. Table 2.

During the titration phase, the incidence of adverse reactions in descending order of percent treatment difference was dyskinesia, nausea, abdominal pain/discomfort, orthostatic hypotension, dizziness, vertigo, hypertension, peripheral edema, and dry mouth. During the maintenance phase, the most frequently observed adverse reactions were dyskinesia, nausea, dizziness, hallucination, somnolence, fall, hypertension, abnormal dreams, constipation, chest pain, bronchitis, and nasopharyngitis. Some adverse reactions developing in the titration phase persisted (≥7 days) into the maintenance phase. These “persistent” adverse reactions included dyskinesia, hallucination, orthostatic hypotension, and dry mouth. The incidence of adverse reactions was similar in women and men. Study 2 was an 18-week, double-blind, placebo-controlled, fixed-dose, dose-response trial in patients with advanced Parkinson’s disease. In Study 2, approximately 7% of patients treated with any dose of ropinirole extended-release tablets discontinued prematurely during the titration phase because of adverse reactions, compared with 4% of patients on placebo. The percentage of patients who discontinued from the study because of an adverse reaction was 4% for ropinirole extended-release tablets 4 mg, 9% for ropinirole extended-release tablets 8 mg, 8% for ropinirole extended-release tablets 12 mg, 8% for ropinirole extended-release tablets 16 mg, and 0% for ropinirole extended-release tablets 24 mg [see Warnings and Precautions ( 5.2 , 5.5 )] . Table 3 lists adverse reactions with an incidence of at least 5% of patients in any dose group of ropinirole extended-release tablets and numerically higher than on placebo in Study 2. The most common adverse reaction (incidence for ropinirole extended-release tablets all doses at least 5% greater than placebo) was dyskinesia. Table 3.

In Study 3, the most commonly observed adverse reactions (≥5%) in patients treated with ropinirole extended-release tablets were nausea (19%), somnolence (11%), abdominal pain/discomfort (7%), dizziness (6%), headache (6%), and constipation (5%). Study 4 was an 18-week, double-blind, placebo-controlled, fixed-dose, dose-response trial in patients with early Parkinson’s disease. Overall, 7% of patients treated with any dose of ropinirole extended-release tablets, including 6% during the titration phase, discontinued prematurely from the study because of adverse reactions compared with 5% of patients on placebo. The percentage of patients discontinuing prematurely because of an adverse reaction was 8% for ropinirole extended-release tablets 2 mg, 5% for ropinirole extended-release tablets 4 mg, 8% for ropinirole extended-release tablets 8 mg, 5% for ropinirole extended-release tablets 12 mg, and 15% for ropinirole extended-release tablets 24 mg. Table 4 lists adverse reactions with an incidence of at least 10% of patients in any dose group of ropinirole extended-release tablets and numerically higher than on placebo in Study 4. The most common adverse reactions (incidence for ropinirole extended-release tablets all doses at least 5% greater than placebo) were nausea, somnolence, sudden onset of sleep, hypertension, and headache.

There was no clear dose response for abnormal shifts in CPK levels in patients with early or advanced stage Parkinson’s disease in either fixed-dose trial. In the fixed-dose trial in early Parkinson's disease patients (Study 4), serum CPK shifted during treatment from normal to above the normal reference range in 10% of patients on ropinirole extended-release tablets and in 5% of patients on placebo. 6.2 Adverse Reactions Observed during the Clinical Development of the Immediate-Release Formulation of Ropinirole Tablets for Parkinson’s Disease (Advanced and Early) Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug (or of another development program of a different formulation of the same drug) and may not reflect the rates observed in practice. In patients with advanced Parkinson's disease who were treated with the immediate-release formulation of ropinirole tablets, the most common adverse reactions (≥5% treatment difference from placebo presented in order of decreasing treatment difference frequency) were dyskinesia (21%), somnolence (12%), nausea (12%), dizziness (10%), confusion (7%), hallucinations (6%), headache (5%), and increased sweating (5%). In patients with early Parkinson's disease who were treated with the immediate-release formulation of ropinirole tablets, the most common adverse reactions (≥5% treatment difference from placebo presented in order of decreasing treatment difference frequency) were nausea (38%), somnolence (34%), dizziness (18%), syncope (11%), asthenic condition (11%), viral infection (8%), leg edema (6%), vomiting (5%), and dyspepsia (5%). 6.3 Postmarketing Experience The following adverse reactions have been identified during postapproval use of ropinirole extended-release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
