I take Losartan which is an angiotensin II receptor, similar to an ACE inhibitor. I also take 12 mg of Hydrochlorothiazide. I take a large dose of Losartan 100mg but I have had HBP since I was 14 years old unusual teenager ever gets it. They have never found cause all kinds of testing and been a marathoner, runner, and cyclist 42 years. It does not seem to cause me problems but my BP can be low after riding long. Beta Blockers are the ones that can take you down as they limit the heart output. I took one of those over 30 years ago for awhile it wiped me out and my pulse dropped crazy. My resting pulse is 40 sometimes 38-39 to Beta Blockers not good.
