Exclusion Criteria

1.Patients with significant diseases other than COPD will be excluded.

2Patients with clinically relevant abnormal baseline hematology, blood chemistry or urinalysis. If the abnormality defines a disease listed as an exclusion criterion, the patient is excluded.
3.All patients with an AST (SGOT) >80 IU/L, ALT (SGPT) >80 IU/L, Bilirubin >2.0 mg/dL or Creatinine >2.0 mg/dL will be excluded regardless of the clinical condition. Repeat laboratory evaluation will not be conducted in these subjects.
4.Patients who have a total blood Eosinophil count =600/mm3. A repeat Eosinophil count will not be conducted in these patients.
5.Patients with a recent history (i.e., one year or less) of myocardial infarction.
6.Patients with a recent history (i.e., three years or less) of heart failure or patients with any cardiac arrhythmia requiring drug therapy.
7.Patients with a history of cancer, other than treated basal cell or fully cured squamous carcinoma, within the last five years.
8.Patients with a history of life-threatening pulmonary obstruction, or a history of cystic fibrosis or clinically evident bronchiectasis.
9.Patients who have undergone thoracotomy with pulmonary resection. Patients with a history of a thoracotomy for other reasons should be evaluated as per exclusion criterion No. 1.
10.Patients with a history of asthma or allergic rhinitis.

15.Patients with known narrow-angle glaucoma.
16.Patients with current significant psychiatric disorders.
17.Patients who regularly use daytime oxygen therapy for more than 1 hour per day and in the investigator’s opinion will be unable to abstain from the use of oxygen therapy.

19.Patients who are being treated with antihistamines for any excluded allergic conditions.
20.Patients using oral corticosteroid medication at unstable doses (i.e., less than 6 weeks on a stable dose) or at a dose in excess of the equivalent of 10 mg of prednisone per day or 20 mg every other day.
21.Initiation of inhaled steroid use, or new dosage, less than 6 weeks prior to the Screening Visit (Visit 1) or during the baseline period.
22.Use of beta-blocker medications, MAO inhibitors or tricyclic antidepressants less than 30 days prior to the baseline period or during the treatment period . Beta blocker eye medications for treatment of non-narrow angle glaucoma are allowed.
