SWITCHING FROM IMMEDIATE-RELEASE TO EXTENDED-RELEASE:
-Patients may be switched overnight from immediate-release tablets to extended-release tablets at the same daily dose; monitor closely to determine if dose adjustments may be necessary.

Comments:
-If a significant interruption in therapy occurs, re-titration may be necessary; upon discontinuation, doses should be tapered.

Use: Treatment of Parkinson's disease

-Normal to mild renal impairment (CrCl greater than 50 mL/min): No adjustment recommended

Extended-release:
Severe renal impairment: Not recommended
Moderate renal impairment (CrCl 30 to 50 mL/min): Initial dose: 0.375 mg orally every other day; after 1 week, may increase to once a day dosing based on therapeutic response and tolerability; subsequent dose titrations should be in increments of 0.375 mg no more frequently every 7 days; Maximum dose: 2.25 mg per day

Restless Legs Syndrome:
Immediate-release:
Moderate to severe renal impairment (CrCl 20 to 60 mL/min): Initial dose: 0.125 mg orally once a day 2 to 3 hours before bedtime
Titration: If needed, dose may be titrated upwards by increments of 0.125 mg every 14 days; Maximum dose: 0.5 mg orally once a day

Liver Dose Adjustments

No adjustment recommended.

Dose Adjustments

If the patient is receiving levodopa, a reduction in the dosage of levodopa should be considered.

Patients may be switched overnight from pramipexole immediate-release to pramipexole extended-release at the same daily dose. Dose adjustment may be needed in some patients.

Discontinuation of Treatment:

-Parkinson's Disease: Taper off at a rate of 0.75 mg per day until the daily dose has been reduced to 0.75 mg, then reduce by 0.375 mg per day.

-Restless Legs Syndrome: Taper is not needed

Precautions

Safety and efficacy have not been established in patients younger than 18 years.

-Upon discontinuation, this drug should be gradually tapered; during clinical trials, this drug was not tapered when used to treat restless legs syndrome.

Monitoring:
-Cardiovascular: Monitor for signs and symptoms of orthostatic hypotension, particularly during dose escalation
-Musculoskeletal: Monitor for posture changes, including neck bending forward, bending forward at the waist, tilting sideways when sitting, standing, or walking
