Inclusion criteria

Healthy male and female subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs (blood pressure (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests
Age of 18 to 50 years (inclusive)
Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)
Signed and dated written informed consent in accordance with ICH Harmonized Guideline for Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial
Male subject, willing to use male contraception (condom or sexual abstinence) and to refrain from sperm donation from time point of administration of trial medication until 90 days after last administration of trial medication, if their sexual partner is a woman of child-bearing potential (WOCBP) or

Female subject who meets any of the following criteria for a highly effective contraception from at least 30 days prior to first administration of trial medication until 5 months after last administration of trial medication:

Use of combined (estrogen and progestogen containing) hormonal contraception that prevents ovulation (oral, intravaginal or transdermal), plus condom in male partner
Use of progestogen-only hormonal contraception that inhibits ovulation (only injectables or implants), plus condom in male partner
Use of intrauterine device (IUD) or intrauterine hormone-releasing system (IUS), plus condom in male partner
Sexually abstinent
Male sexual partner of the trial participant is vasectomized and received medical assessment of the surgical success of the vasectomy (documented absence of sperm)
Surgically sterilized (including hysterectomy, bilateral salpingectomy, bilateral oophorectomy, or bilateral tubal occlusion)
Postmenopausal, defined as no menses for 1 year without an alternative medical cause (in questionable cases a blood sample with levels of follicle-stimulating hormone (FSH) above 40 U/L and estradiol below 30 ng/L is confirmatory)

Exclusion criteria

Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the Investigator
Repeated measurement of systolic BP outside the range of 90 to 140 mmHg, diastolic BP outside the range of 50 to 90 mmHg, or PR outside the range of 50 to 90 bpm
Any laboratory value outside the reference range that the investigator considers to be of clinical relevance (including but not limited to electrolyte disturbances, particularly hypokalemia and hypomagnesemia)
Any evidence of a concomitant disease assessed as clinically relevant by the Investigator
Any known gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, hormonal or immunological disorders (including any known relevant immunodeficiency)
Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)
Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
History of relevant orthostatic hypotension, fainting spells, or blackouts Further exclusion criteria apply
