Brief summary

This study aims to evaluate the possible efficacy and safety of addition of metformin to celecoxib in patients with knee osteoarthritis.

Detailed description

Metformin is a safe, well-tolerated oral biguanide widely used as first-line therapy for type 2 diabetes for over 50 years. In addition to its glucose-lowering effects, metformin modulates inflammatory and metabolic factors resulting in weight loss and reduced inflammation and plasma lipids. Data from animal studies suggest that metformin could limit OA development and progression, possibly through activating AMPK. Retrospective cohort study of participants with OA and type 2 diabetes reported that patients receiving a combination of cyclooxygenase-2 inhibitors and metformin therapy had a lower risk of joint replacement than those receiving cyclooxygenase-2 inhibitors alone . These findings shed light on possible therapeutic potential of metformin in treatment of OA.
