From the Guidelines
Pramipexole is indicated for the treatment of isolated REM sleep behavior disorder (RBD) in adults, with a suggested starting dose of 0.125 mg administered orally at bedtime, which can be increased slowly to 2.0 mg nightly. This recommendation is based on the American Academy of Sleep Medicine clinical practice guideline 1, which suggests that pramipexole may be effective in reducing dream enactment episodes in patients with isolated RBD, particularly those with elevated periodic limb movements noted on polysomnography (PSG).
The mechanism of efficacy of pramipexole in RBD is uncertain, but it may help reduce ancillary motor activity or treat underlying sleep-fragmenting conditions such as periodic limb movement disorder 1. Common side effects of pramipexole include nausea, dizziness, somnolence, and impulse control disorders.
It is essential to note that pramipexole is not the first-line treatment for RBD, and other medications such as clonazepam and melatonin may be considered as alternative options 1. However, pramipexole may be a suitable choice for patients who do not respond to other treatments or have specific comorbidities.
In contrast to its use in RLS, where the AASM suggests against the standard use of pramipexole due to the risk of augmentation 1, the guideline recommends its use in isolated RBD, highlighting the importance of individualized treatment approaches.
Overall, pramipexole may be a valuable treatment option for patients with isolated RBD, and its use should be carefully considered in the context of each patient's unique clinical profile and medical history. Key points to consider when prescribing pramipexole for RBD include:
- Starting dose: 0.125 mg orally at bedtime
- Titration: increase slowly to 2.0 mg nightly as needed
- Mechanism of action: uncertain, but may reduce ancillary motor activity or treat underlying sleep-fragmenting conditions
- Common side effects: nausea, dizziness, somnolence, and impulse control disorders
- Alternative treatments: clonazepam, melatonin, and other medications may be considered.

From the Research
Indications for Pramipexole
- Pramipexole is indicated for the treatment of the signs and symptoms of idiopathic Parkinson's disease 3, 4, 5.
- It is also indicated for the treatment of moderate-to-severe primary restless legs syndrome (RLS) 3, 4, 6, 7.
Treatment of Parkinson's Disease
- Pramipexole can be used as monotherapy in early Parkinson's disease and as adjunctive therapy in advanced disease 3.
- It has been shown to be effective in relieving motor symptoms such as akinesia, rigidity, and tremor at rest 3.
- Pramipexole may also have a beneficial effect on non-motor symptoms such as depression in Parkinson's disease 3.
Treatment of Restless Legs Syndrome
- Pramipexole has been shown to be effective in reducing symptoms of RLS, including periodic limb movements 6, 7.
- It has been found to be well tolerated, with most adverse events being transient and of mild to moderate severity 7.
