The difference between amlodipine and levamlodipine: 1. If the patient has simple hypertension, he can lower his blood pressure by taking levamlodipine, and if he has coronary artery disease, he can take amlodipine for the treatment of the disease. Amlodipine can protect the vascular endothelium, so amlodipine benzoate can also protect blood vessels while lowering blood pressure in patients with coronary artery disease.2. Levo-amlodipine and amlodipine are the same class of anti-hypertensive drugs and there is no difference in anti-hypertensive treatment, the former is a part of the latter and an effective part of anti-hypertensive treatment.3. Amlodipine is a calcium channel inhibitor that can play a role in dilating coronary arteries, relaxing vascular smooth muscle and lowering blood pressure. The antihypertensive effect and absorption of levamlodipine is poor, and the side effects are relatively small, the same as the antihypertensive ability of amlodipine. In clinical treatment, the antihypertensive effect of 2.5 mg of levamlodipine is equivalent to 5 mg of amlodipine.
