The Ropinirole used in the treatment of Parkinson's disease. Oral Ropinirole daily dose is 3 ~ 9mg for three times. If combined with levodopa, you should reduce levodopa by 20%. Aspirin should be withdrawn gradually about 1 week. Ropinirole must be baned from the serious kidney damage (creatinine clearance < 30ml/min) or liver injury patients. It also should be banned in pregnancy, lactation and women to be pregnant. And the one who is allergic to Ropinirole. 2-nitro-6-[2-(di-n-propylamino)ethyl]phenylacetic acid hydrochloride can be used to produce Ropinirole under ambient temperature in ethanol for 5 hour(s) with 5percent Pd/C as catalytic agent and. Yield is 78 % .
