Amlopres 5mg



Amlopres (amlodipine besylate) is a dihydropyridine derivative, and has the following chemical name: 3-ethyl 5-methyl 2-(2-aminoethoxy-methyl)-4-(2-chlorophenyl)-1, 4-dihydro-6-methyl-3,5-pyridine-dicarboxylate benzenesulphonate.


Amlodipine is a dihydropyridine calcium channel blocker. It inhibits the transmembrane influx of calcium ions into cardiac and vascular smooth muscle without affecting serum calcium concentrations. Direct relaxation of vascular smooth muscle forms the basis of the antihypertensive action. In angina pectoris, amlodipine acts as a peripheral arteriolar vasodilator resulting in a reduction in total peripheral resistance (afterload).

Myocardial energy and oxygen requirements are reduced. Amlodipine exerts its activity by binding to the dihydropyridine binding sites. It exerts minimal action on cardiac conduction, contraction and heart rate.


Complete absorption of amlodipine is slow following oral administration, with peak plasma levels being attained after 6 to 12 hours. Amlodipine has a bioavailability of about 64% and a plasma elimination half-life of 35 to 50 hours, allowing for once-daily oral dosing. Steady state plasma concentrations are achieved after 7 to 8 days of consecutive dosing.

The volume of distribution is about 20 L/kg. Metabolism is via the liver and is extensive, with less than 10% of amlodipine appearing unchanged in the urine. Metabolites are inactive and primarily (up to 60%) excreted via the kidney.


AMLOPRES is indicated for the:

• Treatment of angina pectoris.

• Treatment of mild to moderate hypertension, alone or in combination with other antihypertensives.


Hypersensitivity to any of the ingredients.

Hypersensitivity to dihydropyridines.



Use in the Elderly:

Amlodipine clearance is decreased (40 - 60%) in the elderly, which results in increases of amlodipine area under the concentration-time curve (AUC) and elimination half-life. Therefore, elderly patients should start AMLOPRES therapy at a lower dose.

Use in Renal Failure:

Although AMLOPRES is excreted primarily via the kidney, mild renal impairment does not appear to have an effect on plasma concentrations. Severe renal impairment may however require a dosage reduction. Amlodipine is not dialysable.

Use in Impaired Hepatic Function:

The half-life of AMLOPRES is significantly prolonged in patients with impaired hepatic function. AMLOPRES should therefore be administered at lower doses in these patients.

Use in Children:

Safety and efficacy has not been established.

Use in Heart Failure:

An increased incidence of pulmonary oedema has been reported. AMLOPRES may have a negative inotropic effect. AUC of AMLOPRES may increase in patients with heart failure.

Porphyria: Safety has not been established.

Dosage & Administration

Hypertension and Angina Pectoris:

Adults: An initial dose of 5 mg AMLOPRES once daily is recommended which may be increased to 10 mg once a day after 10 - 14 days of therapy if there is no improvement.

No dose reduction is required when adding AMLPORES to thiazide diuretics, beta-blockers, or angiotensin-converting enzyme inhibitors. 

There is no documented experience with AMLPORES overdosage.

Gastric lavage may be of benefit.

Gross overdosage could result in excessive peripheral vasodilation, resulting in marked and probably prolonged systemic hypotension.

Clinically significant hypotension due to AMLPORES overdosage requires active cardiovascular support.

Intravenous calcium gluconate may be of benefit in reversing the effects of calcium channel blockade.

Since amlodipine is highly protein-bound, dialysis is not likely to be of benefit.

Treatment is symptomatic and supportive.


Storage/Handling Recommendations

Do not store above 25 degree C in a dry place and protect from light. Keep out of reach of children.
