Pramipexole dihydrochloride monohydrate is bound to plasma proteins to a very low extent (<20%) and little biotransformation is seen in humans. Therefore, interactions with other medication affecting plasma protein binding or elimination by biotransformation are unlikely. Medication that inhibit the active renal tubular secretion of basic (cationic) drugs or are themselves eliminated by active renal tubular secretion may interact with pramipexole dihydrochloride monohydrate resulting in reduced clearance of either or both medications. (See Table 10.)
