Norvasc is an oral pill made up of a calcium channel blocker called amlodipine. We carry the brand choice and generic alternative of this medication in 5mg and 10mg! Norvasc is used to treat angina and other conditions cause by coronary heart disease as well as lowering blood pressure in those with hypertension.

Coronary heart disease is a condition where the arteries to your heart become narrow due to a plaque (cholesterol and other substances) buildup, limiting the amount of blood and oxygen that can flow to your heart. Coronary heart disease causes health conditions such as chest pain (angina) and an irregular heart beat (heart arrhythmia).

The exact cause of high blood pressure is unknown but can be influenced by the amount of fluid in your body (too much fluid = higher blood pressure) and how much blood your heart pumps (more blood = higher blood pressure). High blood pressure can lead to health complications such as heart attack, stroke, and kidney problems.

Norvasc (amlodipine) is effective in treating these conditions (angina/hypertension) because of its ability to widen blood vessels allowing easier blood flow.

Always follow directions given to you by your doctor. Instructions can usually also be found on the prescription or prescription bottle/container.

You may take Norvasc with or without food, but it must be taken the same way every time.

Ensure you are keeping up with all necessary blood work required while being treated with Norvasc.

Drug manufacturers will chemically change a drug into their salt form to enhance the absorption and overall effectiveness of the medication. Therefore, amlodipine is the drug responsible for the therapeutic effects of Norvasc while amlodipine besylate is the besylate salt of amlodipine, which makes up Norvasc. However, amlodipine besylate is commonly referred as just amlodipine to prevent confusion.

How does amlodipine work?

Amlodipine is effective at treating high blood pressure because it is a calcium channel blocker; this means it can influence the blood vessels. Normally in hypertension patients, the airways are narrow, which makes it harder for blood to flow through. Amlodipine is able to widen the blood vessels to allow improvement within blood flow which ultimately reduces blood pressure. Angina is caused when the heart muscle does not get enough blood supply; a common result of coronary artery disease. So by dilating the blood vessels and improving blood flow, Amlodipine is also effective at preventing angina.
