• Hypertension (High Blood Pressure): Amlodipine is widely prescribed for the management of hypertension. It effectively lowers blood pressure by relaxing the blood vessels, allowing blood to flow more smoothly. This helps to reduce the risk of complications associated with high blood pressure, such as stroke, heart attack, and kidney problems.
• Angina (Chest Pain): Amlodipine is also used to treat angina, a type of chest pain caused by reduced blood flow to the heart muscle. By dilating the coronary arteries, amlodipine improves blood supply to the heart, relieving chest pain and reducing the frequency of angina attacks.
• Coronary Artery Disease (CAD) Prevention: Amlodipine is sometimes prescribed to prevent certain types of heart problems, including coronary artery disease. By lowering blood pressure and improving blood flow to the heart, it helps to reduce the risk of developing CAD and its associated complications, such as heart attack and heart failure.
• Other Conditions: In addition to its primary indications, amlodipine may be used off-label for the treatment of other cardiovascular conditions, such as Raynaud’s phenomenon and hypertrophic cardiomyopathy. However, its effectiveness in these conditions may vary, and it should only be used under the supervision of a healthcare professional.

Amlodipine’s versatility in treating hypertension, angina, and preventing heart-related issues underscores its importance in cardiovascular medicine. However, its use should always be guided by a healthcare provider to ensure proper dosing and monitoring for potential side effects.

• Calcium Channel Blockade: Amlodipine belongs to the class of medications known as calcium channel blockers. It exerts its effects by blocking calcium channels in the cell membranes of vascular smooth muscle cells and cardiac muscle cells.
• Vasodilation: By blocking calcium channels, amlodipine inhibits the influx of calcium ions into smooth muscle cells lining the walls of blood vessels. This leads to relaxation (dilation) of the blood vessels, reducing peripheral resistance and ultimately lowering blood pressure.
• Coronary Vasodilation: Amlodipine’s vasodilatory effects extend to the coronary arteries supplying blood to the heart muscle. By dilating these arteries, amlodipine increases blood flow to the heart, improving oxygen delivery and relieving ischemia (lack of oxygen) that can cause angina.
• Cardiac Effects: Additionally, amlodipine has mild negative inotropic effects, meaning it reduces the force of contraction of the heart muscle. This helps to decrease myocardial oxygen demand, making it beneficial for both angina management and heart failure with preserved ejection fraction (HFpEF).

Overall, amlodipine’s mechanism of action involves vasodilation of peripheral and coronary arteries, resulting in decreased blood pressure, improved blood flow to the heart, and relief of angina symptoms. These effects contribute to its efficacy in treating hypertension and angina pectoris.

• Flushing
• Fatigue

Serious Side Effects (Seek Medical Attention):

• Severe dizziness or fainting
• Rapid or irregular heartbeat
• Shortness of breath
• Severe swelling of the feet, ankles, or hands
• Worsening chest pain (angina)

Less Common Side Effects:

• Nausea or abdominal discomfort
• Muscle cramps

• Palpitations

It’s important to note that not all individuals experience these side effects, and some may experience side effects not listed here. If any side effects persist or worsen, it’s crucial to consult a healthcare professional promptly. Additionally, serious side effects should be reported immediately to a doctor or seek emergency medical attention.

• Pregnancy and Breastfeeding: Use caution during pregnancy and breastfeeding due to potential risks to the fetus or nursing infant.
• Liver Function: Adjustments may be necessary for patients with liver disease.
• Heart Conditions: Use with caution in patients with heart failure or severe aortic stenosis.
• Avoid Grapefruit Juice: Grapefruit juice can interact with amlodipine, leading to increased blood levels.
• Allergy: Patients with a known allergy to amlodipine or other calcium channel blockers should avoid its use.
• Elderly Patients: Start with lower doses in elderly patients due to increased sensitivity.
• Drug Interactions: Inform healthcare providers about all medications, supplements, and herbal products being taken.
• Driving and Machinery: Amlodipine may cause dizziness or drowsiness; use caution when driving or operating machinery.
• Electrolyte Imbalance: Monitor electrolyte levels in patients at risk of electrolyte disturbances.
• Orthostatic Hypotension: Monitor patients for signs of orthostatic hypotension, especially when initiating therapy or adjusting dosage.
• Diabetes: Amlodipine may affect blood sugar levels; monitor diabetic patients closely.
• Emergency Medical Attention: Seek immediate medical attention for severe dizziness, rapid heartbeat, shortness of breath, or other serious side effects.

• CYP3A4 Inducers: Conversely, CYP3A4 inducers like rifampin and St. John’s wort may decrease amlodipine levels, reducing its efficacy. Close monitoring of blood pressure and potential dosage adjustments may be necessary when amlodipine is used concomitantly with these drugs.
• Grapefruit Juice: Grapefruit juice contains compounds that inhibit CYP3A4 activity, leading to increased amlodipine levels in the bloodstream. 
• Beta-Blockers: Concurrent use of amlodipine with beta-blockers (e.g., metoprolol, atenolol) may potentiate the blood pressure-lowering effects of both drugs. Careful monitoring of blood pressure and heart rate is recommended when these medications are used together.
• Other Antihypertensive Agents: Combining amlodipine with other antihypertensive agents, such as ACE inhibitors or diuretics, may result in additive blood pressure-lowering effects. Close monitoring for hypotension is advised when these drugs are used concomitantly.

Hypertension:

• Initial dose: 5 mg orally once daily
• Maintenance dose: 5-10 mg orally once daily, as needed

Angina:

• Initial dose: 5-10 mg orally once daily
