Description
Inclusion Criteria:
- Healthy males aged 30 to 65 years.
- Body mass index 18.0 to 35.0 kg/m2.
- Genotyped with regard to their CYP2D6 status.
Exclusion Criteria:
- Participation in a clinical research study within the previous 3 months
- Radiation exposure, including that from the present study, excluding background radiation but including diagnostic x-rays and other medical exposures, exceeding 5 mSv in the last 12 months or 10 mSv in the last 5 years. No occupationally exposed worker, as defined in the Ionising Radiation Regulations 1999, shall participate in the study.
- Regular alcohol consumption in males >21 units per week.
- Current smokers and those who have smoked within the last 12 months.
- Evidence of renal impairment at screening, as indicated by an estimated creatinine clearance (CLcr) of <90 mL/min using the Cockcroft-Gault equation.
- Use of CYP2D6 inhibitors or inducers in the 28 days prior to IMP administration
