Overview of amlodipine drug class
Amlodipine belongs to a class of drugs known as calcium channel blockers. Calcium channel blockers work by blocking the movement of calcium ions into smooth muscle cells and cardiac muscle cells. This inhibits the contraction of these muscles, leading to vasodilation and a reduction in blood pressure.
Calcium channel blockers are commonly used to treat high blood pressure (hypertension) and certain types of chest pain (angina). They are also sometimes used to manage certain types of irregular heart rhythms (arrhythmias) and to prevent migraine headaches.
How does amlodipine work?
Amlodipine specifically blocks L-type calcium channels in the cell membranes of smooth muscle cells and cardiac muscle cells. By blocking these channels, amlodipine prevents calcium from entering the cells, which inhibits the contraction of these muscles.
The inhibition of smooth muscle contraction leads to vasodilation of the arteries and arterioles, reducing peripheral vascular resistance and lowering blood pressure. This helps to improve blood flow and oxygen supply to the heart.
In cardiac muscle cells, amlodipine reduces the contractility of the heart, which can help to reduce the workload on the heart and prevent angina episodes.
Overall, amlodipine’s mechanism of action helps to relax blood vessels, improve blood flow, and reduce the workload on the heart, leading to better control of blood pressure and relief of angina symptoms.
Mechanism of action
Amlodipine belongs to a class of drugs known as calcium channel blockers. It works by inhibiting the influx of calcium ions into smooth muscle cells and cardiac muscle cells. By blocking the entry of calcium ions, amlodipine relaxes and widens the blood vessels, leading to improved blood flow and reduced blood pressure.
This mechanism of action allows amlodipine to lower blood pressure and prevent certain cardiovascular conditions, such as angina and hypertension. By reducing the workload of the heart, amlodipine helps to improve the oxygen and nutrient supply to the heart.
Calcium Channel Blockers Mechanism
Amlodipine works by selectively blocking calcium channels in the cell membrane of smooth muscle cells and cardiac muscle cells. Calcium channels are responsible for allowing the entry of calcium ions into cells, which is necessary for muscle contraction.
By inhibiting the influx of calcium ions, amlodipine reduces the contractility of smooth muscle cells in the blood vessels, leading to relaxation and widening of the arteries and arterioles. This vasodilation results in decreased peripheral vascular resistance, which leads to a reduction in blood pressure.
In cardiac muscle cells, amlodipine also blocks calcium channels. This prevents excessive calcium ion influx during depolarization, which reduces the contractility of the cardiac muscle. As a result, amlodipine decreases the workload of the heart and improves cardiac output without affecting heart rate.
Additional benefits
Amlodipine’s mechanism of action not only helps to lower blood pressure, but it also provides additional benefits for patients with certain cardiovascular conditions. By dilating the arteries and reducing peripheral vascular resistance, amlodipine improves blood flow to the coronary arteries. This increases the oxygen and nutrient supply to the heart, which can relieve symptoms of angina and reduce the risk of myocardial infarction.
Furthermore, amlodipine’s vasodilatory effects can also improve blood flow to other organs and tissues, reducing the risk of complications associated with atherosclerosis, such as stroke and peripheral artery disease.

Indications
Amlodipine is a calcium channel blocker that is primarily used to treat high blood pressure (hypertension). It is also indicated for the management of chronic stable angina and vasospastic angina (Prinzmetal’s angina) confirmed by exercise testing.
Hypertension:
Amlodipine is effective in lowering blood pressure in both sitting and standing positions. It can be used as a monotherapy or in combination with other anti-hypertensive agents.
Angina:
Amlodipine is used for the management of chronic stable angina, which is characterized by chest pain or discomfort due to coronary artery disease. It helps to reduce the frequency and severity of angina attacks, and also improves exercise tolerance.
Vasospastic Angina (Prinzmetal’s Angina):
Amlodipine is effective in treating vasospastic angina, a type of angina caused by coronary artery spasm. It helps to relieve episodes of chest pain, improves exercise tolerance, and reduces the need for short-acting nitrate medications.
Other Indications:
In addition to the above indications, amlodipine may be used off-label for the treatment of other conditions, such as Raynaud’s phenomenon and heart failure, as recommended by a healthcare professional.
Important Note:
Amlodipine should only be used under the supervision of a healthcare professional. The dosage and duration of treatment should be determined by a qualified medical practitioner based on individual patient factors and medical history.
Dosage and administration
When it comes to the dosage and administration of amlodipine, it’s important to follow the instructions provided by your healthcare professional. They will determine the right dosage for you based on your individual needs and medical condition.
Amlodipine is typically taken orally, with or without food, once a day. It can be taken in the morning or in the evening, depending on what works best for you. It’s important to take the medication at the same time each day to maintain a consistent level in your body.
The recommended starting dose for most adults is 5 milligrams (mg) once daily. However, the dosage may be adjusted based on your blood pressure response. In some cases, a lower dose of 2.5 mg may be prescribed.
If you have liver problems, your healthcare professional may start you on a lower dosage to minimize the risk of side effects.
It’s important to continue taking amlodipine even if you feel well. High blood pressure often has no symptoms, so you may not realize that your condition is improving. Stopping the medication suddenly can cause your blood pressure to rise again.
Missed dose
If you miss a dose of amlodipine, take it as soon as you remember. However, if it’s close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
If you have any questions or concerns about the dosage or administration of amlodipine, be sure to talk to your healthcare professional. They can provide personalized advice and guidance based on your specific situation.
