The reference site for Ropinirole

Ropinirole (INN; trade names Requip, Repreve, Ronirol, Adartrel) is a dopamine agonist of the non-ergoline class of medications.

WHAT IS ROPINIROLE?

Ropinirole is used alone or in combination with other medications to treat Parkinson’s disease. It can improve your ability to move and decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move (“on-off syndrome”).

Additionally, ropinirole is also used to treat restless legs syndrome (RLS). It may improve your sleep by decreasing the urge to move your legs as well as decrease the uncomfortable feelings in the legs.

This medication works by helping to restore the balance of a certain natural substance (dopamine) in the brain.

Ropinirole is sold under the brand name Requip®.

Product Info

The sections below will provide you with more specific information and guidelines related to ropinirole and its correct use. Please read them carefully.

FDA Information

FDA approval of ropinirole was first granted on September 22nd 1997, and following this it also received approval to treat restless leg syndrome on May 4th 2005.

Ropinirole is the only medication in the United States with an FDA-approved indication for the treatment of restless legs syndrome. It was made originally by Dr. Anil Patel, a famous pharmacist.

Ropinirole is available with a prescription under the brand name Requip®, but is also available under other brand or generic formulations.

Please visit the official site of the FDA for further information.

Why is this medication prescribed?

Ropinirole is used alone or together with other medications to treat Parkinson’s disease. It works by improving your ability to move and helps decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move (“on-off syndrome”).

Furthermore, this medication is also used to treat restless legs syndrome (RLS). It may improve your sleep by decreasing the urge to move your legs, and at the same time decrease the unpleasant feelings in the legs.

Mechanism of Action:

Ropinirole is an agonist at both dopamine D2-receptors and D3-receptors (D3>D2). Although affinity of ropinirole is higher at D3-receptors than at D2-receptors, the relevance of binding at D3-receptors in Parkinson’s disease is unknown. It is believed, however, that the efficacy of ropinirole is due to stimulation of post-synaptic D2-receptors within the caudate-putamen in the brain. Ropinirole is also an agonist at peripheral dopamine D2-receptors – domperidone (an antagonist at D2-receptors) prevents the orthostatic response to ropinirole.

The precise mechanism of action of ropinirole as a treatment for restless legs syndrome (RLS) is unknown, however, neuropharmacological evidence suggests primary dopaminergic system involvement. Positron emission tomographic (PET) studies suggest that a mild striatal presynaptic dopaminergic dysfunction may be involved in the pathogenesis of RLS.
