Outcome Measures

Primary Outcomes (1)

  • The objective of the study is to provide safety and tolerability information for oral doses of levodopa and carbidopa administered as a divided dose.

    Safety and tolerability will be assessed by: adverse events (AEs), physical examination, safety laboratory tests, vital signs and electrocardiograms (ECGs).

    5 weeks

Study Arms (1)

Single arm Levodopa/Carbidopa

EXPERIMENTAL

The intervention is dosing with Sinemet® which is an oral tablet containing Levodopa/Carbidopa. Oral administration of 2 × 12.5 mg/50 mg Sinemet® tablet containing 13.5 mg carbidopa (equivalent to 12.5 mg anhydrous carbidopa) and 50 mg levodopa three times a day on Day -1 with 240 mL water Oral administration of 1 × 12.5 mg/50 mg Sinemet® tablets containing 13.5 mg carbidopa (equivalent to 12.5 mg of anhydrous carbidopa) and 50 mg levodopa administered with 100 mL water every hour for 16 hours on Day 1

Drug: Levodopa/Carbidopa (Sinemet)

Interventions

Oral administration of 2 × 12.5 mg/50 mg Sinemet® tablet containing 13.5 mg carbidopa (equivalent to 12.5 mg anhydrous carbidopa) and 50 mg levodopa three times a day on Day -1 with 240 mL water Oral administration of 1 × 12.5 mg/50 mg Sinemet® tablets containing 13.5 mg carbidopa (equivalent to 12.5 mg of anhydrous carbidopa) and 50 mg levodopa administered with 100 mL water every hour for 16 hours on Day 1
