Dear dr, my mom is 74 years old, her blood pressure is high at the moment, 170/105 i gave her 16 mg of candesartan cilexetil, but only went down 150/ 95 within 15 minutes, is that normal? how long will it take for the blood pressure to go down ?

She will need more: If her BP is truly that high, one medicine is not likely to be adequate. Each medicine, on average, lowers BP about 10-15 points. The higher the starting bp, the more one medicine can do, but ~170 is not likely to be down to normal with just one pill. It is not likely she truly has 170/105, and in only 15 min it is down to 150 is not likely from candesartan. Consult with doc for eval. Good luck.

High systolic BP: At age 74, your mother has systolic hypertension which is severely elevated. She is not on maximum therapy, as she is on only 16 mg candesartan; (c); the maximum dose is 32 mg/day. She probably needs another medicine to bring her BP to a systolic < 140 mm of mg. Speak to her doctor about adding another medicine to her c to get her BP under better control. Good luck.
