简要总结
To study the safety and efficacy of tropicamide 1 mg intra-oral slow dissolving muco-adhesive thin films compared to placebo to reduce hypersalivation in PD patients manifesting sialorrhea complaints.
详细描述
This is a double-blind, placebo-controlled, randomized, crossover, multicentre study comparing intra-oral slow dissolving muco-adhesive thin films containing tropicamide 1 mg or Placebo. Patients will receive each treatment twice daily (1 h after breakfast and 1 h after lunch) for 1-week.
Patients will be evaluated for eligibility during the 14-day screening period. Those patients meeting all entry criteria at baseline will be randomized (1:1) to receive first tropicamide followed by placebo films or vice versa. Patients will return for regularly scheduled visits at Weeks 1 and 3 or at early discontinuation.

结局指标
主要结局
modified Teachers Drooling Scale (% responding)
时间窗: one week
The primary endpoint for this trial is the difference in responder rate between tropicamide and placebo. Responders will be defined as subjects whose mean sialorrhea score improved by at least 30% as compared to baseline in the 9-point modified Teachers Drooling Scale (mTDS).
次要结局
- Visual Analg Scale(one week)
- modified Teachers Drooling Scale (mean)(one week)
- Sialorrhea Clinical Scale for Parkinson's Disease (mean)(one week)
- UPDRS Part II sialorrhea item (mean)(one week)
