Have long history of hyper tension including two open heart surgeries. I m taking 2 loser tan (100mg) and 2 carvedilol (6.25 mg) per day. Morning bp usually 130+ / 90+ but after morning meds the bp drops to 110+/ 70+ but by late afternoon or early evening the bp climbs to 160+ / 100+ ( how knows what it drops to during the night)? Would you suggest additional meds in afternoon. Is there a med that is slow release or one that has a longer lasting effect. Have carried extended record of BP to Dr and he says I m worrying to much only take bp several times a week and forget about it. I m worried that this elevated pressure will cause damage
