Why do the elderly take depressor to begin with low dose? 's treatment

The elderly's medicine supersession is slow, the cause that this blood flow volume that is kidney drops with increase of age. The statistics show, every increase is 10 years old after the manhood, renal blood flow is reduced by 10%. The reduction of renal blood flow, make the kidney drop to the clearance ability of the medicine, offer the elderly a medicine of the dosage as young people, the elderly will reduce to the removing rate of medicine because of the kidney, and the medicine density rises in the blood.
On the other hand, when the elderly suffer from hypertension, with small arteriosclerosis of the kidney and fiber more, make glomerular filtration rate reduce, obviously influence the clearance of the medicine of kidney to be applied. In view of these two respect reasons, the medical expert emphasizes the old hypertension patient very much, should begin with low dose while using depressor, can prevent the medicine from accumulating in the body in this way, can avoid stepping down and causing hypotension too fast.
Likewise, treat, make result, need, make a reduction of medicines, should begin with low dose and reduce medicines progressively too. This is because old hypertension is a chronic disease, if it probably causes blood pressure to jump instead to reduce medicines suddenly, appear headache, dizzy and sympathetic nerve to park the intersection of medicine and syndrome, getting heavy to cause the intersection of hypertension and encephalopathy, the intersection of brain and emergence of apoplexy even.
