Amlodipine Besilate is a salt form of amlodipine used as a calcium channel blocker to treat hypertension.
Amlodipine Besilate is the chemical form of amlodipine, a medication that belongs to the calcium-channel blocker class. It works by relaxing the smooth muscle in blood vessels, which helps to lower blood pressure and improve blood flow to the heart. In Hong Kong, amlodipine is available in several products that all contain the active ingredient amlodipine besilate.
Amlodipine Besilate is marketed both as a generic product and under various brand names. The most common formulations are oral tablets that come in 5 mg and 10 mg strengths, designed for once-daily use. Brand-name options you may see in local pharmacies include Norvasc, Amlor, and Rivor, while the generic version is simply labelled “Amlodipine Besilate”. All of these medicines are approved for sale in Hong Kong and follow the same regulatory standards set by the Hong Kong Department of Health.
These uses are recognised by the Hong Kong health authorities and are reflected in the product information for each amlodipine-containing tablet.
Amlodipine Besilate blocks calcium from entering the muscle cells that line the walls of arteries. Without this calcium entry, the arteries stay relaxed and wider, allowing blood to flow more easily. The result is a gradual reduction in blood pressure and less strain on the heart. Effects usually begin within a few hours and continue to improve over the first week of regular use.
