Bioequivalence Study of Carbidopa/Levodopa/Entacapone Combination vs. Carbidopa/Levodopa Combination Plus Entacapone in Healthy Volunteers
A Randomized, Two-Way Crossover Study to Investigate the Bioavailability of a Single Oral Dose of 12.5 mg Carbidopa, 50 mg Levodopa and 200 mg Entacapone Compared to a Single Oral Combined Dose of Both 12.5 mg Carbidopa and 50 mg Levodopa and 200 mg Entacapone in Healthy Volunteers Under Fed Conditions
The purpose of this study is to assess the safety and bioequivalence of a single oral dose of carbidopa+levodopa+entacapone combination versus a single oral dose of carbidopa+levodopa combination plus a single oral dose of entacapone under fed conditions in healthy volunteers.
