* Good physical and mental health status, determined on the basis of medical history and physical examination
* Vital signs (blood pressure, pulse rate, respiratory rate and body temperature) in sitting position within the normal range or showing no clinically relevant deviation per the Investigator's opinion
* All values for laboratory assessments (hematology, clinical chemistry and urinalysis) within the normal range or showing no clinically relevant deviation per the Investigator's opinion

* Non-smoker or smoker less than 10 cigarettes per day
* Women of childbearing potential (WOCBP) who are not nursing, are not pregnant, and are using highly effective methods of birth control. Female participants may also be enrolled if they are postmenopausal or surgically sterilized/ hysterectomized at least 6 months prior to study participation
* WOCBP must have a negative urine pregnancy test at Screening and on each admission (Day 1 of each dosing period)

Exclusion Criteria:

* Participation in a clinical trial/study within 90 days prior to Screening
* Blood donation (equal or more than 300 milliliter \[mL\]) or significant blood loss within 90 days prior to first drug administration
* Any surgical or medical condition, including findings in the medical history or in the prestudy assessments, or any other significant disease, that in the opinion of the investigator, constitutes a risk or a contraindication for the participation of the participant in the study or that could interfere with the study objectives, conduct or evaluation
* History of malignant diseases, except in-situ basal cell skin tumors treated with curative intent
* History of surgery of the gastrointestinal tract which could influence the gastrointestinal absorption and/or motility per the Investigator's opinion
* History or presence of relevant liver diseases or hepatic dysfunction (laboratory result for liver function test greater than equals to (\>=) 1.5 upper limit of normal (ULN)
* History or presence of renal failure or renal dysfunction based on clinical symptoms and finding (serum creatinine concentration \>1.4 milligram per milliliter (mg/mL)
* Ascertained or presumptive hypersensitivity to the active drug substance and/or formulations' ingredients; history of anaphylaxis to drugs or allergic reactions in general, which the Investigator considers may affect the outcome of the study
* Receipt of any prescription or non-prescription medication within 14 days before the first drug administration, except for hormonal contraceptives in female, and including multivitamins and herbal products (e.g. St John's Wort)
* Consumption of large quantities of methylxanthine-containing beverages (\> 5 cups of coffee/day or equivalent)
* Consumption of grapefruit, orange, cranberry or juices of these three fruits, 24 hours prior to drug administration
* Known lack of participant compliance or inability to communicate or cooperate with the Investigator (e.g., language problem, poor mental status)
