Patient B-217, a 58-year-old woman, attends a routine diabetes review. She has type 2 diabetes diagnosed 8 years ago, complicated by albuminuria, and essential hypertension. Current medicines: metformin 500 mg twice daily, amlodipine 5 mg once daily, and ibuprofen 400 mg three times daily for knee osteoarthritis. She has no known drug allergies. She does not smoke. On examination: blood pressure 152/92 mm Hg, pulse 76 beats per minute and regular, body mass index 28 kg/m². Weight 70 kg. Urinalysis shows protein:creatinine ratio 8 mg/mmol. Blood tests: sodium 138 mmol/L, potassium 4.4 mmol/L, creatinine 1.1 mg/dL (eGFR 52 mL/min/1.73 m²), HbA1c 7.8%. She is not pregnant.
