What is Amlodipine Besylate Tablets Usp 5 Mg Tablet?

Amlodipine Besylate Tablets USP 5 mg is an oral antihypertensive formulation containing amlodipine besylate. It belongs to the calcium channel blocker class and is used for the management of hypertension and certain forms of angina. Each tablet provides amlodipine besylate equivalent to the stated 5 mg amlodipine strength.

Uses / Indications

Amlodipine Besylate 5 mg Tablets may be used in the management of:

• Hypertension (high blood pressure)

Medical attention should be sought if severe dizziness, fainting, significant swelling, allergic symptoms, or other serious reactions occur.

How Does It Work?

Amlodipine Besylate

Amlodipine is a dihydropyridine calcium channel blocker. It inhibits the influx of calcium ions into vascular smooth muscle cells. This produces relaxation of arterial smooth muscle and reduces peripheral vascular resistance, thereby lowering blood pressure.

Amlodipine also dilates coronary arteries and arterioles, which can improve coronary blood flow and help reduce myocardial oxygen demand in patients with angina.

Dosage Guidelines

The appropriate dose depends on the patient’s age, indication, blood pressure response, clinical condition, concomitant medicines, and other individual factors.

The exact dose and treatment duration should follow the approved product information and the recommendation of a qualified healthcare professional.

For oral tablets:

• Take exactly as prescribed.
• Swallow the tablet with sufficient water unless otherwise directed.
• Take the medicine according to the prescribed schedule.
• Do not crush, split, chew or dissolve the tablet unless permitted by the approved product information.
• Do not change the dosage without professional advice.

Dose selection may require additional consideration in elderly patients and patients with hepatic impairment.

When Not to Use

Amlodipine Besylate Tablets should generally not be used in patients with:

• Known hypersensitivity to amlodipine, other dihydropyridine calcium channel blockers, or any component of the formulation
• Severe hypotension
• Cardiogenic shock

Particular medical assessment may be required in patients with:

• Severe aortic stenosis
• Heart failure
• Hepatic impairment
• Significant hypotension
• Other cardiovascular conditions requiring careful blood-pressure management

Drug / Product Interactions

Amlodipine may interact with medicines that affect blood pressure or alter its metabolism.

Clinically relevant interaction categories may include:

• Other antihypertensive medicines
• Certain CYP3A4 inhibitors
• Certain CYP3A4 inducers
• Medicines that may increase or decrease blood pressure
• Simvastatin, where dose limitations may be relevant
• Other medicines requiring blood-pressure monitoring

Patients taking multiple medicines should inform their healthcare professional before starting treatment.

Safety Advice

Overdose

If an overdose is suspected, seek immediate medical attention or contact an appropriate poison-control or emergency medical service.

An excessive dose may cause marked hypotension and other cardiovascular effects.

Missed Dose

Take the missed dose when remembered unless it is nearly time for the next scheduled dose. If the next dose is due soon, skip the missed dose and continue with the regular schedule. Do not double the next dose unless specifically instructed by a healthcare professional.

Driving

Dizziness or fatigue may occur, particularly when treatment is initiated or the dose is changed. Patients should understand how the medicine affects them before driving or operating machinery.

Alcohol

Alcohol may contribute to dizziness or lower blood pressure in some patients receiving antihypertensive treatment. Discuss alcohol consumption with a healthcare professional.

Pregnancy

Amlodipine should be used during pregnancy only when clinically indicated and after appropriate medical assessment.

Breastfeeding

The decision to use amlodipine during breastfeeding should be made with a healthcare professional after considering the expected benefits and potential risks.

Children

Use in children should follow the age-specific recommendations of the approved product information and healthcare professional.

Elderly Patients

Older patients may be more sensitive to blood-pressure-lowering effects. Appropriate dose selection and clinical monitoring may be required.

Hepatic Impairment

Amlodipine is extensively metabolised by the liver. Patients with hepatic impairment may require careful dose selection and clinical monitoring.

General Instructions

• Take the medicine according to the prescribed schedule.
• Swallow the tablet with sufficient water unless otherwise directed.
• Do not alter the prescribed dosage without professional advice.
• Do not discontinue long-term antihypertensive treatment without medical advice.
• Keep the medicine in its original packaging where appropriate.
• Do not share prescription medicines with other people.
• Follow the approved product information and healthcare professional’s instructions.
• Attend recommended blood-pressure monitoring appointments where applicable.

Special Dietary / Lifestyle Tips

No specific dietary restriction is generally required unless advised by a healthcare professional.

Patients managing hypertension may be advised to follow a balanced diet, moderate sodium intake where appropriate, maintain a healthy weight, remain physically active according to individual ability, and follow their healthcare professional’s recommendations.

Comparison with Other Treatments

Amlodipine is a dihydropyridine calcium channel blocker that primarily produces arterial vasodilation. Other antihypertensive medicines, such as ACE inhibitors, angiotensin receptor blockers, beta-blockers, and diuretics, act through different mechanisms.

Amlodipine may be used alone or as part of combination antihypertensive therapy depending on the patient’s clinical circumstances. The selection of treatment depends on factors such as blood pressure, cardiovascular conditions, concomitant diseases, other medicines, tolerability, and the approved indication.

Precautions & Warnings

• Confirm any history of hypersensitivity to amlodipine or related calcium channel blockers.
• Monitor blood pressure, particularly when treatment is initiated or adjusted.
• Use with appropriate medical assessment in patients with severe aortic stenosis.
• Patients with hepatic impairment may require careful dose selection.
• Use cautiously in patients with significant hypotension.
• Peripheral oedema may occur during treatment.
• Patients with heart failure should receive appropriate medical assessment.
• Dizziness or hypotension may affect driving or operation of machinery.
• Inform the healthcare professional about all medicines being taken, including medicines that may affect amlodipine metabolism.
• Seek medical attention if severe allergic symptoms, fainting, or significant cardiovascular symptoms develop.

Can I Use It With Other Medicines?

Generally Compatible With

Amlodipine can be used with many medicines when clinically appropriate. Compatibility depends on the patient’s complete medication profile and medical condition.
