Rotigotine

12.1 Mechanism of Action Rotigotine is a non-ergoline dopamine agonist. The precise mechanism of action of rotigotine as a treatment for Parkinson's disease is unknown, although it is thought to be related to its ability to stimulate dopamine receptors within the caudate-putamen in the brain. The precise mechanism of action of rotigotine as a treatment for Restless Legs Syndrome is unknown but is thought to be related to its ability to stimulate dopamine receptors.

1 INDICATIONS AND USAGE NEUPRO is a dopamine agonist indicated for the treatment of: Parkinson's disease ( 1.1 ) Moderate-to-severe primary Restless Legs Syndrome ( 1.2 ) 1.1 Parkinson's Disease (PD) NEUPRO is indicated for the treatment of Parkinson's disease. 1.2 Restless Legs Syndrome (RLS) NEUPRO is indicated for the treatment of moderate-to-severe primary Restless Legs Syndrome.

2 DOSAGE AND ADMINISTRATION Parkinson's disease: Initially, 2 mg/24 hours for early-stage disease or 4 mg/24 hours for advanced-stage disease. The dose may be increased as needed by 2 mg/24 hours at weekly intervals, up to 6 mg/24 hours for early-stage disease and up to 8 mg/24 hours for advanced-stage disease. ( 2.1 ) Restless Legs Syndrome: Initially, 1 mg/24 hours, increased as needed by 1 mg/24 hours at weekly intervals, up to 3 mg/24 hours. ( 2.2 ) Apply once a day to the skin; press firmly in place for 30 seconds. Do not place NEUPRO on oily, irritated, or damaged skin, or where it will be rubbed by tight clothing. Do not use the same site more than once every 14 days. The prescribed dose may be achieved using single or multiple patches. ( 2.3 ) To discontinue treatment, reduce the dose gradually until complete withdrawal of NEUPRO. ( 2.4 ) 2.1 Dosage in Parkinson's Disease Early-Stage Parkinson's Disease In patients with early-stage Parkinson's disease, the recommended starting dose for NEUPRO is 2 mg/24 hours. Based upon individual patient clinical response and tolerability, NEUPRO dosage may be increased weekly by 2 mg/24 hours if additional therapeutic effect is needed. The lowest effective dose is 4 mg/24 hours. The maximum recommended dose for early-stage Parkinson's disease is 6 mg/24 hours. Advanced-Stage Parkinson's Disease In patients with advanced-stage Parkinson's disease, the recommended starting dose for NEUPRO is 4 mg/24 hours. Based upon individual patient clinical response and tolerability, NEUPRO dosage may be increased weekly by 2 mg/24 hours if additional therapeutic effect is needed. The maximum recommended dose for advanced-stage Parkinson's disease is 8 mg/24 hours. 2.2 Dosage in Restless Legs Syndrome In patients with Restless Legs Syndrome, the recommended starting dose for NEUPRO is 1 mg/24 hours. Based upon individual patient clinical response and tolerability, NEUPRO dosage may be increased weekly by 1 mg/24 hours if additional therapeutic effect is needed. The lowest effective dose is 1 mg/24 hours. The maximum recommended dose is 3 mg/24 hours. 2.3 Administration Information NEUPRO is applied once a day. The adhesive side of the transdermal system should be applied to clean, dry, intact healthy skin on the front of the abdomen, thigh, hip, flank, shoulder, or upper arm. The transdermal system should be applied at approximately the same time every day, at a convenient time for the patient. Because NEUPRO is administered transdermally, food is not expected to affect absorption and it can be applied irrespective of the timing of meals. The application site for NEUPRO should be moved on a daily basis (for example, from the right side to the left side and from the upper body to the lower body). NEUPRO should not be applied to the same application site more than once every 14 days and should not be placed on skin that is oily, irritated, or damaged, or where it will be rubbed by tight clothing. If it is necessary to apply NEUPRO to a hairy area, the area should be shaved at least 3 days prior to NEUPRO application. The system should be applied immediately after opening the pouch and removing the protective liner. The system should be pressed firmly in place for 30 seconds, making sure there is good contact, especially around the edges. If the patient forgets to replace NEUPRO, or if the transdermal system becomes dislodged, another transdermal system should be applied for the remainder of the day. The prescribed dose may be achieved using single or multiple patches [see Patient Counseling Information (17) ]. 2.4 Discontinuation of NEUPRO For discontinuation of NEUPRO in patients with Parkinson's disease, reduce the daily dose by a maximum of 2 mg every 24 hours preferably every other day, until complete withdrawal of NEUPRO is achieved. For discontinuation of NEUPRO in patients with Restless Legs Syndrome, reduce the daily dose by 1 mg every 24 hours preferably every other day, until complete withdrawal of NEUPRO is achieved.

6 ADVERSE REACTIONS The following serious adverse reactions are discussed below and elsewhere in the labeling: Sulfite Sensitivity [see Warnings and Precautions (5.1) ] Falling Asleep During Activities of Daily Living and Somnolence [see Warnings and Precautions (5.2) ] Hallucinations/Psychosis [see Warnings and Precautions (5.3) ] Symptomatic Hypotension [see Warnings and Precautions (5.4) ] Syncope [see Warnings and Precautions (5.5) ] Impulse Control/Compulsive Behaviors [see Warnings and Precautions (5.6) ] Elevation of Blood Pressure and Heart Rate [see Warnings and Precautions (5.7) ] Weight Gain and Fluid Retention [see Warnings and Precautions (5.8) ] Dyskinesia [see Warnings and Precautions (5.9) ] Application Site Reactions [see Warnings and Precautions (5.10) ] Augmentation and Rebound in RLS [see Warnings and Precautions (5.11) ] Hyperpyrexia and Confusion [see Warnings and Precautions (5.14) ] Withdrawal Symptoms [see Warnings and Precautions (5.15) ] Fibrotic Complications [see Warnings and Precautions (5.16) ] Parkinson's disease: Most common adverse reactions (at least 5% greater than placebo) were nausea, vomiting, somnolence, application site reactions, dizziness, anorexia, disturbances in initiating and maintaining sleep, hyperhidrosis, visual disturbance, peripheral edema, and dyskinesia. ( 6.1 ) Restless Legs Syndrome: Most common adverse reactions (at least 5% greater than placebo) were application site reactions, nausea, disturbances in initiating and maintaining sleep, somnolence, and headache.

Adverse Reactions in Early-Stage Parkinson's Disease The safety of NEUPRO was evaluated in a total of 649 early-stage Parkinson's disease patients who participated in three double-blind, placebo-controlled studies with durations of 3 to 9 months. Additional safety information was collected in short-term studies and two open-label extension studies in patients with early-stage Parkinson's disease. In the double-blind, placebo-controlled, dose-response study in patients with early-stage Parkinson's disease, the most common adverse reactions (at least 5% greater than placebo) for the maximum recommended dose of NEUPRO (6 mg/24 hours) were nausea, vomiting, somnolence, application site reactions, dizziness, anorexia, disturbances in initiating and maintaining sleep, hyperhidrosis, and visual disturbance. In this trial, 12% of patients treated with the maximum recommended NEUPRO dose (6 mg/24 hours) discontinued treatment because of adverse reactions, compared with 6% of patients who received placebo. Table 1 summarizes the adverse reactions that occurred in greater than 2% of NEUPRO-treated patients and more frequent than in placebo-treated patients in a double-blind, placebo-controlled, fixed-dose trial in patients with early-stage Parkinson's disease. Incidences for the non-recommended 8 mg/24 hours dose are also shown.

During the titration phase, this increased incidence of a treatment difference was observed for nausea, somnolence, vomiting, application site reactions (ASRs), dizziness, sweating increased, anorexia, and visual disturbance. During the maintenance phase, an increased incidence was observed for nausea and ASRs. Some adverse reactions developing in the titration phase persisted (at least 7 days) into the maintenance phase.
