2. Healthy male subjects aged 18 to 55 years (inclusive) with suitable veins for cannulation or repeated venipuncture
3. Have a body mass index (BMI) between 18 and 29.9 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive.
4. Subjects should be willing to follow reproductive restrictions #11 in Section 7.47.4.1 to prevent pregnancy and drug exposure of a female partner and refrain from donating sperm or fathering a child from the first day of dosing until 3 months after the last dose of IMP.
5. Be able to inhale from the DPI devices according to given instructions.
6. Able to understand, read and speak the German language.

Exclusion Criteria:

1. History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
2. History or presence of gastrointestinal, hepatic or renal disease or any other condition known to interfere with absorption, distribution, metabolism or excretion of drugs.
3. Known Gilbert's syndrome, family history of Gilbert's syndrome or suspicion of Gilbert's syndrome based on liver function tests.
4. Any contraindication against the use of vagolytic or sympaticomimetic drugs, as judged by the Investigator.
5. Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
6. Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results, as judged by the Investigator.
7. Any positive result on screening for serum hepatitis B surface antigen (HBsAg), hepatitis B core antibodies (anti HBc Ab), hepatitis C antibody and human immunodeficiency virus (HIV).

8. Abnormal vital signs, after 10 minutes supine rest (confirmed by 1 controlled measurement), defined as any of the following:

   • Systolic BP (SBP) < 90 mmHg or ≥ 140 mmHg
   • Diastolic BP (DBP) < 50 mmHg or ≥ 90 mmHg
   • Pulse < 50 or > 90 beats per minute (bpm)
9. Subject with forced expiratory volume in 1 second (FEV1) < 80% of the predicted value regarding age, height, gender and ethnicity (European Community for Coal and Steel [ECCS/European Respiratory Society [ERS]) at screening.
10. Subject with an acute infection of the upper and lower airway or other clinical relevant infections, which are not resolved at least 3 weeks before first drug administration.
11. Subjects who are not able to perform correct spirometry tests at screening.
12. Any clinically significant abnormalities in rhythm, conduction or morphology of the resting ECG and any clinically significant abnormalities in the 12 lead ECG, as considered by the Investigator that may interfere with the interpretation of QTc interval changes, including abnormal ST T wave morphology, particularly in the protocol defined primary lead or left ventricular hypertrophy.
13. Prolonged Fridericia's correction (QTcF) > 450 ms or family history of long QT syndrome.
14. PR (PQ) interval prolongation (> 200 ms) intermittent second (Wenckebach block while asleep is not exclusive) or third degree atrioventricular (AV) block, or AV dissociation.
15. Persistent or intermittent complete bundle branch block (BBB), incomplete bundle branch block (IBBB), or intraventricular conduction delay (IVCD) with QRS > 110 ms. Subjects with QRS > 110 ms but < 115 ms are acceptable if there is no evidence of, for example, ventricular hypertrophy or pre excitation.
16. Known or suspected history of drug abuse, as judged by the Investigator.
17. Current smokers or those who have smoked or used nicotine products (including e cigarettes) within the previous 3 months.
18. History of alcohol abuse or excessive intake of alcohol, as judged by the Investigator.
19. Positive screen for drugs of abuse or cotinine (nicotine) at screening or admission to the Clinical Unit.
20. History of severe allergy/hypersensitivity or ongoing clinically significant allergy/hypersensitivity, as judged by the Investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD7594.
21. Excessive intake of caffeine containing drinks or food (e.g., coffee, tea, chocolate), as judged by the Investigator.
22. Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks prior to the first administration of IMP.
23. Use of any prescribed or non prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to the first administration of IMP or longer if the medication has a long half life.
24. Plasma donation within one month of screening or any blood donation/blood loss > 500 mL during the 3 months prior to screening.

25. Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or one month after the last visit whichever is the longest.

    Note: Subjects consented and screened, but not randomized in this study or a previous phase I study, are not excluded.

26. Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
27. Involvement of any Astra Zeneca or study site employee or their close relatives.
28. Judgment by the Investigator that the subject should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions and requirements.
