Brief summary: The test formulation of Budesonide Inhalation Aerosol is bioequivalent to the reference formulation in healthy Chinese subjects under fasting conditions.

Detailed description: In a four-period single-dose oropharyngeal inhalation study of the investigational drug, with a washout period of 3 days. After dosing, subjects should thoroughly rinse their mouth with 150 ml of water and spit out the rinse water.

Blood plasma concentrations of budesonide are collected within the specified sampling time for pharmacokinetic parameter analysis. In each period, blood samples are collected at pre-dose 0 h and at 0.03, 0.07, 0.10, 0.13, 0.17, 0.20, 0.25, 0.33, 0.42, 0.50, 0.75, 1, 2, 4, 6, 8, 10, 12, and 16 h post-dose.

Eligibility criteria: Inclusion Criteria:

1. \*\*Age\*\*: Chinese male or female subjects aged 18 to 65 years (inclusive of the boundary values).
2. \*\*Weight\*\*: Males must weigh ≥50.0 kg, and females must weigh ≥45.0 kg. The Body Mass Index (BMI) calculated as \\\[ \\text{BMI} = \\frac{\\text{weight (kg)}}{\\text{height}\^2 (\\text{m}\^2)} \\\] must be between 19.0 and 26.0 kg/m² (inclusive of the boundary values).
3. \*\*Informed Consent\*\*: Subjects must fully understand the purpose, nature, methods, and potential adverse reactions of the trial and voluntarily sign a written informed consent form.

3. \*\*Examination\*\*: Subjects with a measured FEV1/predicted FEV1 ≤ 80% or FVC ≤ 80% of the predicted value in pulmonary function tests; or subjects whose pulmonary function test results are judged by the investigator to indicate small airway disease.
4. \*\*Inquiry\*\*: Subjects with a history or current diagnosis of chronic or severe diseases of the liver, kidneys, endocrine system, urinary system, digestive system, blood, or lymphatic system.
