About

The goal of this clinical trial is to compare the acute bronchodilator effect of the Ipratropium / Levosalbutamol 1.25 mg & 0.5 mg / 2.5 mL fixed dose combination nebuliser solution or Levosalbutamol 1.25 mg / 3 mL nebuliser solution and Ipratropium 500 mcg nebuliser solution in stable moderate-severe-very severe COPD patients.

Enrollment: 74 estimated patients

Sex: All

• Hospitalization due to COPD or pneumonia within the last 3 mounts prior the screening visit.
• SGOT (serum glutamic-oxaloacetic transaminase) >80 IU/L, SGPT (serum glutamic-pyruvic transaminase) >80 IU/L, bilirubin >2.0 mg/dL or creatinine >2.0 mg/dL.
• History of asthma, significant chronic respiratory diseases (i.e., significant bronchiectasis, interstitial lung diseases, etc.) other than COPD or presence of disease that may be serious and/or potentially affect results of the study.

• History of lung volume reduction surgery
• Drug or alcohol abuse
• Presence of active tuberculosis
• History of atopy or allergic rhinitis
• Presence of active cancer
