Why the Sudden INR Increase?

A 76-year-old man is admitted with increasing shortness of breath. He has a long history of chronic obstructive pulmonary disease (COPD) and has had a recent productive cough. He is admitted to the hospital and treated with amoxicillin, prednisone, codeine, and albuterol.

His medical history is notable for atrial fibrillation, hypertension, COPD, and gastroesophageal reflux disease. His current medications include metoprolol, warfarin, pantoprazole, and lisinopril. His most recent international normalized ratio (INR) obtained 2 weeks ago was 2.2; on hospital day 6, it has almost doubled to 4.3.
