Mr. Johnson was started on amlodipine 5 mg for BP control 4 weeks ago in addition to his daily Lisinopril 20mg/HCTZ 25 mg daily. He also takes Advair 250/50 BID and albuterol PRN for asthma.

4 weeks after starting amlodipine, his average BP is 145/88 (goal < 140/90). He has no complaints. What is your next step?
1) Increase amlodipine to 10 mg daily
2) Add 25 mg HCTZ daily
3) Add metoprolol 25 mg daily
4) Continue on current medication regimen
