   Females:

   FEV1 predicted (L) = 3.95 x [height (inches)/39.37] - 0.025 x age (yrs) - 2.60

   or Height measured in meters

   Males:

   FEV1 predicted (L) = 4.30 x [height (meters)] - 0.029 x age (yrs) - 2.49

   Females:

   FEV1 predicted (L) = 3.95 x [height (meters)] - 0.025 x age (yrs) - 2.60

4. Patients must have a diagnosis of chronic bronchitis symptoms i.e., cough and sputum expectoration on most days for at least three months in each of two consecutive years.
5. Patients must be a current or ex-smoker with a smoking history of sup or egal to 10 pack years (Patients who have never smoked cigarettes must be excluded).

2. Patients with an acute or chronic hepatitis or alpha one antitrypsin deficiency or other liver disease.
3. Patients with an aspartate aminotransferase (AST), alanine aminotransferase (ALT) 1.5 x the upper limit of the normal range will be excluded regardless of the clinical condition. A repeat laboratory evaluation will not be conducted in these patients.
4. Patients with history of asthma or allergic rhinitis.
5. Patients with history of post-nasal drip the last 3 months prior visit 1.
6. Patients with a clinical diagnosis of bronchiectasis.
