OK does anyone know any other reason than bp that we do not give beta blockers and ace inhibitors together. At our hospital the pharmacy times them two hours apart. An old cardiac nurse asked me "why the betas and aces two hours apart, why not the betas and calcium channel blockers"? OK I said because of BP and so did pharmacy. We all know that our patients take them all together and dont space them. Of course when we a patient is taking them for the first time we would want to watch the bp closely.....but does anyone else know of any reason? Thanks
