Participant Flow

This single center Phase II study was initated on 02 Aug 2011. First patient was screened on 25 Aug 2011. All the study patients were recruited from medical clinic and the patient recruitment ended on 23 Aug 2012.The last study patient completed study on 19 Sep 2012.

After informed consent process, investigators screened 35 patients and successfully randomized 24 patients to receive study treatments. The other 11 patients were screening failure since they failed to meet study required inclusion and/or exclusion criteria.

SECONDARY outcome

Timeframe: 8 hours post-dose

Evaluation of change from baseline the subjective assessment of saliva production after administration of a single dose of different combinations of oxybutynin and clonidine (OC Oral solution) in patients suffering from Parkinson's disease with excessive salivation. Compare with baseline the number of rate scale was more production with baseline or reduce from baseline. The min and max of the score is 0 and 10, the total range is 0\~10, and higher value is represented more worse outcome.

Evaluation of the safety and tolerability of different combinations of oxybutynin and clonidine (OC Oral solution) in patients suffering from Parkinson's disease with excessive salivation. Calculate the treatment Emergent Adverse Events number during the study treatment period and follow up period up to at least 23 days excluding the screening period.
