Administration of ESR 1150 CL in Ascending Doses of 0.5, 1, 2, 4 and 8 mg in an Open, Group Comparison and Placebo-controlled Design (Placebo Randomised Double Blind in the Dose Groups) for the Assessment of Safety, Tolerability (Maximum Tolerated Dose, MTD), Pharmacokinetics and Pharmacodynamics in 5 Groups of 8 Female and 5 Male Healthy Subjects, and 4 mg Additionally in Fed State, in a Cross Over Design. Safety, Tolerability and Pharmacokinetics of MTD/4, MTD/2 and MTD in 6 Healthy Male Subjects, Identified as CYP2D6 and/or "Spartein" Poor Metabolizers, in a 3-fold Cross Over, Open Study.
