Amlodipine benzoate and amlodipine benzoate, there is no difference between the two in terms of their therapeutic significance. The former is a part of the latter and the effective part of its antihypertensive, and its spin is levulinic. In addition to the hypotension of amlodipine dextro in general, its efficiency is only 1/2000 of that of amlodipine levulinate, so the hypotensive effect of 2.5mg of amlodipine benzoate is comparable to that of 5mg of amlodipine benzoate. However, amlodipine besylate contains both levo-amlodipine and dextro-amlodipine. Dexamlodipine can induce the release of endogenous nitric oxide in blood vessels, which has a protective effect on the endothelium of blood vessels. Therefore, in patients with coronary artery disease, amlodipine benzoate can protect blood vessels while lowering blood pressure.
