Randomized Controlled Trial Comparative Study Clinical Trial
Preferential D2 or preferential D3 dopamine agonists in restless legs syndrome.
A comparison between equivalent low doses of the D2 preferential agonist bromocriptine and the D3 preferential agonist pramipexole was performed in order to understand which dopamine agonist receptor subtype plays the main role in the treatment of restless legs syndrome (RLS) with periodic leg movements during sleep (PLMS). ⋯ This study provides Class III evidence that for patients with RLS pramipexole as compared to an estimated equivalent dose of bromocriptine results in greater improvement in some measures of RLS and PLMS severity after one night of treatment.
