- Calcium channel blocker medications block the transport of calcium into the smooth muscle cells lining the arteries of the heart (coronary arteries) and other arteries of the body. Since the action of calcium is important for muscle contraction, blocking calcium transport relaxes arterial muscles and expands (dilates) coronary arteries and other arteries of the body. By dilating coronary arteries, Amlodis increases the flow of blood to the heart and is useful in preventing heart pain (angina) resulting from reduced flow of blood to the heart caused by coronary artery spasm (contraction). Relaxing the muscles lining the arteries in the rest of the body lowers blood pressure, which reduces the work that the heart must do to pump blood to the body. Reducing the work of the heart also lessens the heart muscle's need for oxygen, and thereby further helps to prevent angina in patients with coronary artery disease.
Q: I just started Norvasc and have hypothyroidism. Could this medicine affect my thyroid?
A: Norvasc (Amlodis) is a calcium channel blocker used to treat high blood pressure and other heart conditions. Generally speaking, drug interactions fall into three main categories: Drug-drug (i.e., prescription, over-the-counter, herbals, dietary supplements) interactions occur when two or more drugs react with each other. Drug-diet (food/drink) interactions result from drugs reacting with foods or drinks. Drug-disease interactions may occur when an existing medical condition makes certain drugs potentially harmful. Potential drug interactions 1) Norvasc has an interaction with grapefruit juice. It is best to avoid grapefruit and grapefruit juice while taking Norvasc. Taking them together may lead to increased side effects from Norvasc. According to prescribing information, Norvasc is not expected to affect the thyroid. When your doctor prescribes a new medication, be sure to discuss all your prescription and over-the-counter drugs, including dietary supplements, vitamins, botanicals, minerals, and herbals, as well as the foods you eat. Always keep a current list of the drugs and supplements you take and review it with your healthcare providers and your pharmacist. If possible, use one pharmacy for all your prescription medications and over-the-counter products. This allows your pharmacist to keep a complete record of all your prescription drugs and to advise you about drug interactions and side effects. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action.
