Long-term treatment with dopamine D3 receptor agonists induces a behavioral switch that can be rescued by blocking the dopamine D1 receptor

Restless legs syndrome (RLS) is commonly treated with the dopamine agonists, pramipexole and rotigotine, which target the inhibitory dopamine receptor subtype, D3R. While initially highly effective, these compounds lose their efficacy in treating RLS over time, and long-term therapy regularly leads to a worsening of the symptoms (augmentation). This dopamine agonist-induced augmentation has become a prime concern in the treatment of RLS, and while alternate therapies are being proposed, the mechanisms leading to augmentation remain opaque.
