The absence of urine protein after taking antihypertensive drugs indicates that the kidney damage caused by hypertension is still relatively mild and has improved significantly after treatment. And some antihypertensive drugs themselves can play a role in reducing urine protein and protecting the kidneys. Such as angiotensin converting enzyme inhibitors and angiotensin receptor blockers. Commonly used drugs include enalapril, benazepril, valsartan, irbesartan, temisartan, etc. They can dilate the renal arteries and the glomerular arteries entering and leaving the glomerulus, thus reducing the leakage of albumin. Antihypertensive drugs can reduce the pressure on the renal blood vessels and also assist in reducing urine protein. Urine protein is prone to recurrence, so it is important to pay attention to regular review in the future.
