Bioequivalence Study of Entacapone,Levodopa and Carbidopa Tablets in the Postprandial State in Healthy Chinese Subjects
December 13, 2023 updated by: Cao Yu, The Affiliated Hospital of Qingdao University
Single-Center, Open, Randomized, Single-Dose, Completely Repeated Crossover Bioequivalence Study to Evaluate the Effects of the Test/Reference Preparation, Entacapone,Levodopa and Carbidopa Tablets (II) in the Postprandial State in Healthy Adult Subjects
In this trial, 36 healthy subjects are planned to be enrolled in postprandial, and the postprandial trials will be randomized separately.
According to the randomization table, subjects will be randomly assigned to one of the two groups (Group A: TRTR, Group B: RTRT).
The washout period (dosing interval) between doses will be at least 2 days.
Taking the washout period of 2 days as an example, all subjects will take the corresponding medication according to the randomization table on day 1 of the first cycle trial, day 3 of the second cycle trial, day 5 of the third cycle trial, and day 7 of the fourth cycle trial.
