Amlodac 5 mg

Product Overview

Amlodac 5 mg contains amlodipine besylate, a long-acting calcium channel blocker (CCB) used in the management of hypertension and angina. Manufactured by Zydus Healthcare, it is supplied in 5 mg tablets with a pack size of 180 tablets.

Amlodipine is widely prescribed due to its efficacy in reducing blood pressure, improving coronary blood flow, and its convenient once-daily dosing schedule.

Drug Class

Amlodac belongs to the dihydropyridine calcium channel blocker class. These drugs act primarily on vascular smooth muscle, leading to vasodilation and decreased systemic vascular resistance.

Indications

Clinical Use

• Hypertension (essential high blood pressure)
• Chronic stable angina
• Vasospastic (Prinzmetal's) angina

Therapeutic Role

Amlodipine is frequently used:

• As first-line antihypertensive therapy
• In combination with ACE inhibitors, ARBs, beta-blockers, or diuretics

Mechanism of Action

Amlodipine inhibits L-type calcium channels in vascular smooth muscle, resulting in:

• Relaxation of arterial walls
• Reduced peripheral resistance
• Lower blood pressure
• Improved oxygen supply to the heart

Its long half-life (30–50 hours) supports sustained therapeutic effect with once-daily administration.

Dosage & Administration

• Initial dose: 5 mg once daily
• Adjustment range: 2.5–10 mg daily
• Maximum dose: 10 mg/day

Amlodac 5 mg is a standard starting dose for most adult patients.

It may be taken at any time of day, with or without food, but should be taken consistently at the same time daily.

Use in Females

Amlodipine is commonly prescribed in women and is generally well tolerated. Considerations include:

• Safe for most adult females
• Use during pregnancy only if clearly indicated

Pre-Treatment Assessment

Before initiating Amlodac:

• Assess baseline blood pressure
• Evaluate cardiovascular risk profile
• Check liver function in susceptible individuals

Routine monitoring is recommended during treatment.

Comparative Analysis

Amlodipine vs Other Calcium Channel Blockers

• Longer duration of action compared to nifedipine
• Lower incidence of reflex tachycardia
• Better adherence due to once-daily dosing

Amlodipine vs Other Antihypertensives

• Effective as monotherapy or in combination
• Does not significantly affect electrolyte balance (unlike diuretics)
• Does not directly impact renin-angiotensin system

Risk Management

Common Side Effects

• Peripheral edema (ankle swelling)
• Headache
• Flushing
• Dizziness

Serious Side Effects

• Severe hypotension
• Worsening angina (rare)
• Allergic reactions

Peripheral edema is the most common dose-related adverse effect.

Mitigation Strategies

• Start with appropriate dose (e.g., 5 mg)
• Combine with ACE inhibitors/ARBs to reduce edema
• Monitor regularly for blood pressure response

Drug Interactions

• CYP3A4 inhibitors: may increase amlodipine levels
• Other antihypertensives: additive effects
• Grapefruit juice: may alter metabolism

Sourcing & Selection

When selecting amlodipine products, consider:

• Manufacturer reputation (e.g., Zydus Healthcare)
• Consistent tablet quality and packaging
• Regulatory compliance and authenticity

Conclusion

Amlodac 5 mg (amlodipine) is a widely used and effective calcium channel blocker for managing hypertension and angina. Its long duration of action, ease of use, and well-established safety profile make it a cornerstone therapy in cardiovascular medicine.
