Inclusion criteria:
- Healthy males and females according to the following criteria:
- Based upon a complete medical history, including physical examination, vital signs (Blood Pressure (BP), Pulse Rate (PR)), 12-lead Electrocardiogram (ECG), clinical laboratory tests
- Age ≥21 to ≤50 years
- Minimum weight 50kg - both males and females
- Body Mass Index ≥18.5 to ≤29.9 kg/m2
- Signed and dated written informed consent in accordance with Good Clinical Practice (GCP) and local legislation prior to admission to the trial
- Male or female patients. Women of childbearing potential1 must be ready and able to use highly effective methods of birth control per International Committee on Harmonisation (ICH) M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly e.g. implants, injectables, combined hormonal contraceptives, intrauterine device, or surgical sterilisation (including hysterectomy). In addition to this, also a barrier method (e.g. male condom) will be required, if the female is not surgically sterilised. A list of contraception methods meeting these criteria is provided in the patient information. Abstaining from sexual activity (if this is the usual lifestyle of the subject) is considered an acceptable method of birth control.

- Use of drugs which might reasonably influence the results of the trial based on the knowledge at the time of protocol preparation within 14 days prior to randomisation
- Participation in another trial with an investigational drug within 2 months prior to administration or during the trial
- Smoker (>10 cigarettes or >3 cigars or >3 pipes/day)

- A history of additional risk factors for torsade de pointes (e.g., heart failure, hypokalaemia, family history of Long QT Syndrome)
Special exclusion criteria:

- For female subjects of childbearing potential only:
Positive pregnancy test, pregnancy or planning to become pregnant during the study or within 2 months after study completion
- No adequate contraception during the study including three months before first dosing until 2 month after study completion.
- Lactation
Administrative reasons:
- Subjects suspected or known not to follow instructions
- Subjects who are unable to understand the written and verbal instructions, in particular regarding the risks and inconveniences they will be exposed to during their participation in the study
The exclusion criteria are chosen to assure that subjects with specific risks for administration of the investigational medicinal products and subjects with conditions, which may have an impact on pharmacokinetic parameters, cannot be included
