high blood pressure
"I have been taking this medicine every morning for the past six months and it has reduced by blood pressure from 155/105 to 138/88.  It has a Beta-blocker and makes me feel calmer shortly after taking it.  Although, I find it harder to get going with my cardiovascular exercise.  My doctor recently added an additional drug, amlodipine (calcium channel blocker) to my treatment regimen.  My heart rate went down to a constant 42 beats per minute, which made me very tired and dizzy."
