Ropiniroledosage

Ropinirole extended-release tablets are taken once daily, with or without food; tablets must be swallowed whole and not be chewed, crushed, or divided.

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.

Renal Impairment: In patients with end-stage renal disease on hemodialysis, the maximum recommended dose is 18 mg/day.

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.

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.

2.1 General

Dosing Recommendations

Ropinirole extended-release tablets are taken once daily, with or without food.

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. 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. 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 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 Total Daily Dose (mg) Ropinirole Extended-Release Tablets 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.

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.
