Healthy Subjects, Pharmacokinetics of YM178
Conditions
Keywords
Pharmacokinetics, Phase I, YM178, Modified release (Oral Controlled Absorption System (OCAS)), Immediate release (IR), Fasted conditions, Fed conditions
Brief summary
The purpose of the study is to investigate how quickly and to what extent YM178 is absorbed and eliminated from the body, and how well it is tolerated, when given in three different tablet formulations (sustained release) once a day with and without food, and to compare the results with the profile of the YM178 immediate release formulation taken twice daily without food.
Detailed description
Subjects reside in the clinical research unit for 3 periods of 11 days each, with a washout period of at least 7 days between treatment periods. . Each subject is treated with multiple oral doses of the IR formulation (b.i.d.) under fasted conditions and, OCAS-F, OCAS-M or OCAS-S formulation (q.d.) under fasted and fed conditions (high fat breakfast). The study is completed with a post-study visit between 7 and 14 days after discharge of period 3.
