MIRAPEXIN is indicated in adults for treatment of the signs and symptoms of idiopathic Parkinson’s disease, alone (without levodopa) or in combination with levodopa, i.e. over the course of the disease, through to late stages when the effect of levodopa wears off or becomes inconsistent and fluctuations of the therapeutic effect occur (end of dose or “on off” fluctuations).
MIRAPEXIN is indicated in adults for symptomatic treatment of moderate to severe idiopathic Restless Legs Syndrome in doses up to 0.54 mg of base (0.75 mg of salt) (see section 4.2).
The daily dose is administered in equally divided doses 3 times a day.
Doses should be increased gradually from a starting dose of 0.264 mg of base (0.375 mg of salt) per day and then increased every 5-7 days. Providing patients do not experience intolerable undesirable effects, the dose should be titrated to achieve a maximal therapeutic effect.
Ascending dose schedule of MIRAPEXIN:
| Week | Dose (mg of base) | Total Daily Dose (mg of base) | Dose (mg of salt) <>_.Total Daily Dose (mg of salt) | |
|---|---|---|---|---|
| 1 | 3 × 0.088 | 0.264 | 3 × 0.125 | 0.375 |
| 2 | 3 × 0.18 | 0.54 | 3 × 0.25 | 0.75 |
| 3 | 3 × 0.35 | 1.1 | 3 × 0.5 | 1.50 |
If a further dose increase is necessary the daily dose should be increased by 0.54 mg of base (0.75 mg of salt) at weekly intervals up to a maximum dose of 3.3 mg of base (4.5 mg of salt) per day. However, it should be noted that the incidence of somnolence is increased at doses higher than 1.5 mg (of salt) per day (see section 4.8).
The individual dose of pramipexole should be in the range of 0.264 mg of base (0.375 mg of salt) to a maximum of 3.3 mg of base (4.5 mg of salt) per day. During dose escalation in pivotal studies, efficacy was observed starting at a daily dose of 1.1 mg of base (1.5 mg of salt). Further dose adjustments should be done based on the clinical response and the occurrence of adverse reactions. In clinical trials approximately 5% of patients were treated at doses below 1.1 mg of base (1.5 mg of salt). In advanced Parkinson’s disease, pramipexole doses higher than 1.1 mg of base (1.5 mg of salt) per day can be useful in patients where a reduction of the levodopa therapy is intended. It is recommended that the dose of levodopa is reduced during both the dose escalation and the maintenance treatment with MIRAPEXIN, depending on reactions in individual patients (see section 4.5).
Abrupt discontinuation of dopaminergic therapy can lead to the development of a neuroleptic malignant syndrome. Pramipexole should be tapered off at a rate of 0.54 mg of base (0.75 mg of salt) per day until the daily dose has been reduced to 0.54 mg of base (0.75 mg of salt). Thereafter the dose should be reduced by 0.264 mg of base (0.375 mg of salt) per day (see section 4.4).
The elimination of pramipexole is dependent on renal function. The following dose schedule is suggested for initiation of therapy:
Patients with a creatinine clearance above 50 ml/min require no reduction in daily dose or dosing frequency.
In patients with a creatinine clearance between 20 and 50 ml/min, the initial daily dose of MIRAPEXIN should be administered in two divided doses, starting at 0.088 mg of base (0.125 mg of salt) twice a day (0.176 mg of base/0.25 mg of salt daily). A maximum daily dose of 1.57 mg pramipexole base (2.25 mg of salt) should not be exceeded.
In patients with a creatinine clearance less than 20 ml/min, the daily dose of MIRAPEXIN should be administered in a single dose, starting at 0.088 mg of base (0.125 mg of salt) daily. A maximum daily dose of 1.1 mg pramipexole base (1.5 mg of salt) should not be exceeded.
If renal function declines during maintenance therapy the MIRAPEXIN daily dose should be reduced by the same percentage as the decline in creatinine clearance, i.e. if creatinine clearance declines by 30%, then the MIRAPEXIN daily dose should be reduced by 30%. The daily dose can be administered in two divided doses if creatinine clearance is between 20 and 50 ml/min and as a single daily dose if creatinine clearance is less than 20 ml/min.
Dose adjustment in patients with hepatic failure is probably not necessary, as approx. 90% of absorbed active substance is excreted through the kidneys. However, the potential influence of hepatic insufficiency on MIRAPEXIN pharmacokinetics has not been investigated.
The safety and efficacy of MIRAPEXIN in children below 18 years has not been established. There is no relevant use of MIRAPEXIN in the paediatric population for the indication of Parkinson’s Disease.
The recommended starting dose of MIRAPEXIN is 0.088 mg of base (0.125 mg of salt) taken once daily 2-3 hours before bedtime. For patients requiring additional symptomatic relief, the dose may be increased every 4-7 days to a maximum of 0.54 mg of base (0.75 mg of salt) per day (as shown in the table below).
Dose Schedule of MIRAPEXIN:
| Titration | Step Once Daily Evening Dose (mg of base) | Once Daily Evening Dose (mg of salt) |
|---|---|---|
| 1 | 0.088 | 0.125 |
| 2* | 0.18 | 0.25 |
| 3* | 0.35 | 0.50 |
| 4* | 0.54 | 0.75 |
* if needed
Patient’s response should be evaluated after 3 months treatment and the need for treatment continuation should be reconsidered. If treatment is interrupted for more than a few days it should be re-initiated by dose titration carried out as above.
Since the daily dose for the treatment of Restless Legs Syndrome will not exceed 0.54 mg of base (0.75 mg of salt) MIRAPEXIN can be discontinued without tapering off. In a 26 week placebo controlled trial, rebound of RLS symptoms (worsening of symptom severity as compared to baseline) was observed in 10% of patients (14 out of 135) after abrupt discontinuation of treatment. This effect was found to be similar across all doses.
The elimination of pramipexole is dependent on renal function. Patients with a creatinine clearance above 20 ml/min require no reduction in daily dose. The use of MIRAPEXIN has not been studied in haemodialysis patients, or in patients with severe renal impairment.
Dose adjustment in patients with hepatic failure is not required, as approx. 90% of absorbed active substance is excreted through the kidneys.
MIRAPEXIN is not recommended for use in children and adolescents below 18 years due to a lack of data on safety and efficacy.
MIRAPEXIN is not recommended for use in children and adolescents below 18 years since the efficacy and safety has not been established in this population. MIRAPEXIN should not be used in children or adolescents with Tourette Disorder because of a negative benefit-risk balance for this disorder (see section 5.1).
The tablets should be taken orally, swallowed with water, and can be taken either with or without food.
There is no clinical experience with massive overdose. The expected adverse reactions would be those related to the pharmacodynamic profile of a dopamine agonist, including nausea, vomiting, hyperkinesia, hallucinations, agitation and hypotension. There is no established antidote for overdose of a dopamine agonist. If signs of central nervous system stimulation are present, a neuroleptic agent may be indicated. Management of the overdose may require general supportive measures, along with gastric lavage, intravenous fluids, administration of activated charcoal and electrocardiogram monitoring.
