Eligibility Criteria:
Inclusion Criteria:~1. Provision of signed and dated, written informed consent prior to any study specific procedures.~2. Healthy male and/or female subjects aged 18 years (inclusive) and older, with suitable veins for cannulation or repeated venipuncture.~3. Females must have a negative pregnancy test at screening and on first admission to the unit, must not be lactating.~4. Body mass index (BMI) between 18 and 30 kg/m2 inclusive and weigh at least 50 kg and no more than 100 kg inclusive.~5. Forced expiratory volume in 1 second (FEV1) ≥ 80% of predicted value and FEV1/Forced vital capacity (FVC) ratio ≥ 70%.~6. Non-smokers.~Exclusion Criteria:~1. History of any clinically significant disease or disorder which, in the opinion of the investigator, may either put the volunteer at risk because of participation in the study, or influence the results or the volunteer's ability to participate in the study.~2. History of diagnosed COPD or asthma. (Note: Subjects with a history of childhood asthma only will not be excluded from the study).~3. History or presence of gastrointestinal, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.~4. Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of investigational medicinal product (IMP).~5. Any clinically significant abnormalities in clinical chemistry, 12-lead electrocardiogram (ECG) at screening, haematology, or urinalysis results at screening or vital signs at screening and first admission to the study unit.~6. Any positive result on screening for serum hepatitis B surface antigen (HBsAg), hepatitis C antibody and human immunodeficiency virus (HIV) antibody.~7. Known or suspected history of alcohol or drug abuse or excessive intake of alcohol.~8. Participation in another clinical study with a non-biologic investigational product or new formulation of a marketed non-biologic drug within 3 months prior to the screening visit.~9. Participation in another clinical trial with any marketed or investigational biologic within 4 months or 5 half-lives whichever is longer, prior to the screening visit.~10. Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening.~11. History of severe or ongoing allergy/hypersensitivity (e.g., food allergy) or history of hypersensitivity to drugs with a similar chemical structure or class to Symbicort.~12. Positive screen for drugs of abuse, alcohol or cotinine at screening and on first admission to the study unit.~13. Use of drugs with enzyme-inducing properties such as St John's Wort within 3 weeks prior to the first administration of IMP.~14. 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. (Note: Hormonal contraception and hormonal replacement therapy are allowed for females, as applicable).~15. Involvement of any AstraZeneca, PAREXEL or study site employee or their close relatives.~16. 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.~17. Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
