Exclusion Criteria: History of pallidotomy, thalamotomy, deep brain stimulation or fetal tissue transplantation Dementia, active mental illness or hallucination, major depression Those who received dopamine receptor agonists within 28 days before baseline Patients receiving levodopa preparation (including levodopa compound preparation) within 28 days before baseline, or levodopa preparation after diagnosis for more than 6 months Patients receiving any of the following drugs within 28 days before baseline: amphetamine, metoclopramide, α-methyldopa, antipsychotics, MAO-Ainhibitors, flunarizine, reserpine, methylphenidate, budesonide, etc Active central nervous system drugs (such as sedatives, hypnotics, antidepressants, and antianxiety drugs) are under treatment, except those who have maintained a stable dose for at least 28 days before the baseline (visit 2) and may remain stable during the study period Atypical Parkinson's disease symptoms caused by taking drugs (such as metoclopramide, flunarizine), hereditary metabolic diseases of nervous system (such as Wilson's disease), encephalitis, cerebrovascular diseases or degenerative diseases (such as progressive supranuclear paralysis) Have a history of epilepsy, or have a history of stroke or transient cerebral ischemia within 1 year before the visit Those who are intolerant or allergic to the following antiemetic drugs, such as domperidone, trimethoxybenzamide, ondansetron, tropisetron, granisetron and glinbromide Patients with clinically significant abnormal liver function were defined as total bilirubin > 1.5 times of the upper limit of the reference value range or ALT or ast > 2 times of the upper limit of the reference value range Patients with clinically significant renal dysfunction (serum creatinine > 2.0 mg / dl [> 177 μ mol / l]) Patients with uncontrollable or important cardiovascular diseases, including congestive heart failure of NYHA grade II or above, unstable angina pectoris, myocardial infarction within 6 months before the first administration of trial drug, or arrhythmia requiring treatment at the time of screening At screening, QTc interval: male > 450ms, female > 460ms Patients with a history of orthostatic hypotension, or those with SBP ≥ 20mmhg or DBP ≥ 10mmhg at screening (visit 1) and baseline (visit 2) when switching from supine position to upright position for 1 or 3 minutes; or those with SBP < 105mmhg at visit 1 and visit 2; Subjects with evidence of impulse control disorder (ICD) during screening (visit 1); A history of suicide attempt (including actual attempt, interruption or failure of attempt) or suicidal ideation in the past 6 months were defined as those who answered yes to question 4 or question 5 of the Columbia suicide severity rating scale (c-ssrs) during screening (visit 1); Patients with history of narcolepsy; Those who had a history of alcoholism, drug abuse and drug abuse in the past five years (visit 1) were screened. Alcoholism was defined as drinking more than 14 units of alcohol per week (1 unit = 360 ml beer or 45 ml alcohol with 40% alcohol content or 150 ml wine); Patients with malignant tumor within 5 years before screening were excluded from cervical carcinoma in situ, skin basal cell or squamous cell carcinoma, local prostate cancer after radical operation and breast intraductal carcinoma in situ after radical operation; Pregnant or lactating women; The patients who had participated in the rotigotine test were intolerable or ineffective; Allergic constitution (allergic to two or more drugs or foods) or known to be allergic to rotigotine or rotigotine microspheres; Those who have participated in clinical trials of other drugs within 3 months before screening; Other clinically significant medical status, mental status or laboratory abnormalities judged by the researcher may interfere with the subject's ability to participate in the study.
