Norvasc 5mg (Amlodipine) Tablet x100

Norvasc 5mg (Amlodipine) is a widely prescribed calcium channel blocker medication used to effectively manage hypertension (high blood pressure) and certain types of angina (chest pain caused by reduced blood flow to the heart). This effective medication promotes vasodilation to reduce blood pressure and improve cardiac blood flow.

Uses

Norvasc 5mg is primarily indicated for treating hypertension, either alone or combined with other antihypertensive medications. It effectively manages chronic stable angina pectoris and vasospastic angina (Prinzmetal’s angina). Norvasc helps control blood pressure in various patient populations.

Benefits

• Effectively lowers blood pressure through vasodilation
• Reduces cardiac workload and improves oxygen supply
• Prevents cardiovascular complications development
• Once-daily dosing improves medication adherence
• Generally well-tolerated with low severe side effect risk
• Provides sustained 24-hour blood pressure control
• Improves exercise tolerance in angina patients
• Compatible with most other cardiovascular medications

How It Works

Norvasc contains amlodipine, a dihydropyridine calcium channel blocker that blocks calcium ion entry into smooth muscle cells lining blood vessels. This inhibits muscle contraction, causing vasodilation and subsequent blood pressure reduction. Additionally, Norvasc improves blood flow and oxygen supply to heart muscle, effectively alleviating angina symptoms.

Dosage

Take Norvasc at the same time daily, with or without food. Dosage adjustments may be needed based on patient response and blood pressure readings.

Duration of Action

Norvasc begins working within 2-4 hours of administration, with peak effects occurring at 6-8 hours. Its long half-life provides sustained blood pressure control for 24 hours, making once-daily dosing effective. Full therapeutic benefits for blood pressure control typically develop within 2-4 weeks of regular use.

Side Effects

Common side effects include headache, dizziness, flushing, peripheral edema (ankle swelling), fatigue, and nausea. Less common effects may include palpitations, abdominal pain, and muscle cramps. Most side effects are mild and tend to decrease with continued Norvasc use.

Warning

Use Norvasc with caution in patients with liver or kidney impairment, as dosage adjustments may be necessary. Avoid or use cautiously in patients with heart failure or aortic stenosis. Do not discontinue abruptly as this may cause rapid blood pressure increase.

Pregnancy and Breastfeeding

Norvasc should be used during pregnancy only when potential benefits justify risks to the fetus. Limited data exists on safety during pregnancy. Amlodipine passes into breast milk in small amounts. Consult healthcare provider before taking Norvasc while breastfeeding.

Interaction

• Enhanced effects with CYP3A4 inhibitors like ketoconazole and itraconazole
• Possible interaction with certain anticonvulsants
• May interact with immunosuppressant medications
• Potential additive effects with other antihypertensive drugs
• Grapefruit juice may increase blood levels of amlodipine

Precaution

Regular monitoring of blood pressure and heart rate is essential during Norvasc treatment. Patients should rise slowly from sitting or lying positions to prevent dizziness. Inform all healthcare providers about Norvasc use before procedures. Store at room temperature away from moisture and heat.

Important Information

Norvasc requires consistent daily use for optimal blood pressure control. Missing doses may cause blood pressure fluctuations. Lifestyle modifications including diet, exercise, and weight management enhance Norvasc effectiveness. Regular follow-up appointments are crucial for monitoring treatment response and adjusting dosage as needed.
