Overview

The purpose of this study is to investigate the safety and tolerability of Metformin and how it changes blood markers associated with aging in persons who have chronic obstructive pulmonary disease (COPD) who do not have diabetes.

Interventions

  • Drug Metformin
    All enrolled participants will receive open-label Metformin for a treatment period of 6 months.

Primary outcome measures

  • Determine feasibility of metformin administration in older persons with COPD without diabetes [Time frame: 6 months]
  • Determine acceptability of metformin administration in older persons with COPD without diabetes [Time frame: 6 months]
  • Determine safety of metformin administration in older persons with COPD without diabetes [Time frame: 6 months]
  • Determine tolerability of metformin administration in older persons with COPD without diabetes [Time frame: 6 months]

  • Persons with an unstable medical condition (including but not limited to unstable angina, acute heart failure exacerbation, acute neurological symptoms) or COPD exacerbation within 30 days prior to enrollment will be excluded
  • Active treatment with Carbonic Anhydrase Inhibitors including but not limited to topiramate, zonisamide, acetazolamide, diclofenamide
