Brief summary: The primary purpose of this study is to demonstrate the equivalence of budesonide, glycopyrronium, formoterol (BGF) metered dose inhaler (MDI) hydrofluoroolefin (HFO) with a spacer to BGF MDI hydrofluoroalkane (HFA) with a spacer. The secondary objective is to characterize BGF MDI HFO with and without a spacer.

Detailed description: This study is a Phase I, randomized, partial double-blind, single dose, single-center, 3-way cross over study to assess the pharmacokinetic (PK) and safety of BGF MDI in healthy participants (male or female).

The study will comprise:

1. A Screening Period of up to 27 days prior to first dosing.
2. Three treatment periods: Participants will be resident at the Clinical Unit from Day -1 until 24 hours after dosing with the final treatment.
3. Follow-up: A final Follow-up Phone Call within 5 to 7 days after the last administration of BGF MDI in Treatment Period 3.

Participants will receive all 3 treatments as a single dose (4 inhalations) (Treatment A \[BGF MDI HFA with AeroChamber Plus Flow-Vu spacer with charcoal, reference formulation\], Treatment B \[BGF MDI HFO with AeroChamber Plus Flow-Vu spacer with charcoal - test formulation\], and Treatment C \[BGF MDI HFO without spacer with charcoal\]) (1 treatment per treatment period) in one of 6 possible treatment sequences; ABC, ACB, BAC, BCA, CAB, or CBA.

There will be a 3 to 7 days washout period between each dose administration.

Eligibility criteria: Inclusion Criteria:

* Females must have a negative pregnancy test at screening and on admission to the Clinical Unit, must not be lactating.
* Have a body mass index (BMI) between 18 and 30 kilograms per meter square (kg/m\^2) inclusive and weigh at least 50 kilograms (kg).
* Have a FEV1 greater than or equal to (\>=) 80 percentage (%).
* Demonstrate basic understanding of how to use an MDI device with and without a spacer after receiving training.
* Participants should be fully/sufficiently vaccinated as per local definitions against severe acute respiratory syndrome coronavirus type 2 (SARS CoV-2).

Exclusion Criteria:

* History or current evidence of any clinically significant disease or disorder, including endocrinological diseases, such as thyrotoxicosis, which, in the opinion of the investigator, may either put the participant at risk because of participation in the study, or influence the results through participation in the study.
* History or presence of gastrointestinal, hepatic, or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
* Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of investigational medicinal product (IMP).
* History of narrow angle glaucoma or change in vision.
* History of symptomatic prostatic hypertrophy or bladder neck obstruction/urinary retention.
* Unresectable cancer that has not been in complete remission for at least 5 years.
* Any clinically significant abnormalities in clinical chemistry, hematology, or urinalysis results.
* Any clinically significant abnormal findings in physical examination or vital signs at screening, as judged by the investigator. Eg., Systolic blood pressure (BP) less than (\<) 90 millimeters of Mercury (mmHg) or greater than or equal to (\>=) 140 mmHg and diastolic BP \< 50 mmHg or \>=90 mmHg; Heart rate \< 50 beats per minute (bpm) or \> 90 bpm.
* Any clinically significant abnormalities on 12-lead electrocardiogram (ECG) at screening, as judged by the investigator.
* Any positive result on screening for serum hepatitis B surface antigen (HBsAg) OR anti-hepatitis B core (HBc) antibody, indicative of hepatitis B, hepatitis C antibody, or human immunodeficiency virus (HIV).
* Positive reverse transcription polymerase chain reaction (RT-PCR) test for SARS-CoV-2 prior to randomization.
* Participant has clinical signs and symptoms consistent with Coronavirus disease 2019 (COVID-19), eg, fever, dry cough, dyspnea, sore throat, fatigue, new smell or taste disorder or confirmed infection by appropriate laboratory test within the last 4 weeks prior to screening or on admission.
* Participant who had severe course of COVID-19 (ie, hospitalization, extracorporeal membrane oxygenation, or mechanically ventilated).
* Recent (within 14 days prior to admission to the Clinical Unit) exposure to someone who has COVID-19 symptoms or tested positive for SARS-CoV-2.
* History of any respiratory disorders such as asthma, Chronic obstructive pulmonary disease (COPD), or idiopathic pulmonary fibrosis.
