This study will examine how to dose Exubera (inhaled insulin) in patients who are not well
controlled on two or more diabetes pills. This study should show that a large number of
patients enrolled in the study can reach the target Hemoglobin A1C levels (7% or less) that
have been set by the American Diabetes Association (ADA). Target goals should be achieved by
adjusting the Exubera dose either weekly or twice weekly. Patients will also receive
nutritional counseling and diabetes education as part of the study.
