Mr. Johnson follows up for his BP 4 weeks after increasing his amlodipine from 5 mg to 10 mg. He is currently taking 20 mg lisinopril/25 mg HCTZ qAM and 10 mg amlodipine qAM. His average BP is 132/76. He complains of lower extremity edema and requests a change in his medications because of this. Which choice is a good next step?
1) Lisinopril 20/HCTZ 25 mg qAM, change amlodipine 10 mg to qHS
2) Lisinopril 20/HCTZ 25 mg BID
3) Lisinopril 20/HCTZ 25 mg, decrease amlodipine to 5 mg daily, and add furosemide 10 mg daily
4) Lisinopril 40 mg, HCTZ 25 mg, decrease amlodipine to 5 mg daily
