Amlodipine is a highly effective medication for treating high blood pressure and lowering the risk of heart disease.

It belongs to a class of drugs called calcium channel blockers, which work by relaxing and widening the blood vessels, allowing blood to flow more easily.

This medication is commonly prescribed to help control hypertension and prevent complications such as heart attack and stroke.

What sets amlodipine apart from other medications is its long-lasting effects, providing 24-hour blood pressure control with just one daily dose.

Amlodipine is also well tolerated by many patients, with few reported side effects. Additionally, it can be used in combination with other blood pressure medications to achieve optimal control.

If you have been diagnosed with high blood pressure or any related condition, talk to your healthcare provider about the benefits of amlodipine and how it can improve your cardiovascular health.

Interactions with other medications and substances

Amlodipine may interact with certain medications and substances, potentially affecting their efficacy or causing adverse effects. It is important to discuss all medications and substances you are currently taking with your healthcare provider before starting amlodipine treatment.

Medication/Substance Possible Interaction
Other antihypertensive drugs Amlodipine can enhance the hypotensive effects, leading to low blood pressure. Dosage adjustment may be necessary.
ACE inhibitors While amlodipine and ACE inhibitors are commonly prescribed together to manage hypertension, there is a potential risk of increased hypotensive effects. Regular monitoring of blood pressure is recommended.
Beta-blockers Combining amlodipine with beta-blockers may lead to increased heart rate or cardiac effects. Adjusting the dosage of both medications may be necessary.
Grapefruit and grapefruit juice Grapefruit and its juice can interfere with the metabolism of amlodipine, leading to increased blood levels. Avoid consuming grapefruit while taking amlodipine.
Statins Amlodipine can increase the levels of statins in the blood, potentially resulting in an increased risk of statin-related side effects. Regular monitoring and dosage adjustment may be necessary.
Nonsteroidal anti-inflammatory drugs (NSAIDs) NSAIDs, such as ibuprofen or naproxen, can reduce the efficacy of amlodipine in lowering blood pressure. It is advised to use NSAIDs cautiously while taking amlodipine.
