ephedrine, clen & albuterol are all beta agonists (they bind to beta receptors & thats what makes them work). so should you take a BP drug that is a beta blocker, it cancels out.... ace inhibitors (angiotensin-converting-enzyme inhibitor) and calcium channel blockers are other types of meds that deal with high bp in different ways. lisinopril is an ace inhibitor. ace inhibitors are generally pretty mild for most and often combined with other bp meds. let me be the first to tell you that the only reason your bp is in the pre-hypertensive range is because of the lisinopril u r taking... from what i know , you cant really buy BP meds online or from your dealer. go to a doctor & have him get you on some meds. if it were me, i wouldnt tell him you are taking all the stuff im taking... but that is YOUR CHOICE. I AM NOT SAYING YOU SHOULD DO OR TAKE ANYTHING. im not a Dr.
