PRODUCT INTRODUCTION
description
Pramipexole is a member of the class of benzothiazoles that is 4,5,6,7-tetrahydro-1,3-benzothiazole in which the hydrogens at the 2 and 6-pro-S-positions are substituted by amino and propylamino groups, respectively. It has a role as an antiparkinson drug, a dopamine agonist, an antidyskinesia agent and a radical scavenger. It is a member of benzothiazoles and a diamine. It is a conjugate base of a pramipexole(2+).
