The name of your medicine is Ropinirole-GA; it is also known as ropinirole. Ropinirole-GA is used to treat restless legs syndrome. Restless legs syndrome is a condition in which a sense of uneasiness, restlessness, and itching often accompanied by twitching and pain is felt in the legs and sometimes arms when sitting or lying down, especially in bed at night. The only relief is walking or moving the affected limbs, which often leads to problems sleeping at night time. Restless legs syndrome is thought to be due to a deficiency in the body of a naturally occurring body chemical: dopamine. Ropinirole-GA belongs to a group of medicines called non-ergoline, dopamine agonists. Ropinirole-GA works by having a similar effect on the body as dopamine, therefore it makes up for the dopamine shortage in restless legs syndrome. This in turn relieves the discomfort and reduces the involuntary limb movements that disrupt night time sleep. Your doctor may have prescribed Ropinirole-GA for another reason.

Studies with human cloned receptors _in vitro_ show that ropinirole binds with high affinity to cloned human D 2 , D 3 and D 4 receptors. Neither ropinirole hydrochloride nor its metabolites bind with high affinity to dopamine D 1 receptors. Ropinirole hydrochloride also has very low affinity for 5-HT 1 , 5-HT 2 , benzodiazepine, GABA, muscarinic, alpha- 2 or beta-adrenoceptors. Przeczytaj cały dokument
