Requip Indication
For the treatment of the signs and symptoms of idiopathic Parkinson's disease. Also used for the treatment of restless legs syndrome.
Requip Pharmacology
Ropinirole is a nonergot dopamine agonist with high relative in vitro specificity and full intrinsic activity at the D2 subfamily of dopamine receptors, binding with higher affinity to D3 than to D2 or D4 receptor subtypes. The relevance of D3 receptor binding in Parkinson's disease is unknown. The mechanism of ropinirole-induced postural hypotension is presumed to be due to a D2 -mediated blunting of the noradrenergic response to standing and subsequent decrease in peripheral vascular resistance.
Requip Absorption
Absolute bioavailability is 55%, indicating a first pass effect. Food does not affect the extent of absorption.
