PHARMAMAX 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 arteriolor 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/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.
PHARMAMAX AMLODIPINE 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
PHARMAMAX AMLODIPINE clearance is decreased (40-60%) in the elderly, which results in increases of amlodipine concentration in the area under the concentration-time curve (AUC) and elimination half-life. Therefore, elderly patients should start PHARMAMAX AMLODIPINE therapy at a lower dose.
Use in Renal Failure
Although PHARMAMAX AMLODIPINE is excreted primarily via the kidneys, mild renal impairment does not appear to have an effect on the plasma concentrations. Severe renal impairment may however require a dosage reduction. Amlodipine is not dialysable.
Use in impaired Hepatic Function
The half-life of PHARMAMAX AMLODIPINE is significantly prolonged in patients with impaired hepatic function.
PHARMAMAX AMLODIPINE should therefore be administered at lower doses in those patients.
Use in Children
Safety and efficacy hove not been established.
Use in Heart Failure
An increased incidence of pulmonary oedema has been reported. PHARMAMAX AMLODIPINE may have a negative inotropic effect. AUC of PHARMAMAX AMLODIPINE may increase in patients with heart failure.
Safety has not been established.
Concurrent administration of sublingual nitroglycerin, long acting nitrates, beta-blockers or other antianginal agents with amlodipine may cause severe hypotension.
PREGNANCY AND LACTATION
Safety in pregnancy and lactation has not been established (see CONTRA-INDICATIONS).
DOSAGE AND DIRECTIONS FOR USE
Hypertension and Angina Pectoris
An initial dose of 5 mg PHARMAMAX AMLODIPINE 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 PHARMAMAX AMLODIPINE to thiazide diuretics, beta-blockers, or angiotension converting enzyme inhibitors.

KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS TREATMENT
There is no documented experience with PHARMAMAX AMLODIPINE overdosage. Gastric lavage may be of benefit. Gross overdosage could result in excessive peripheral vasodilatation, resulting in marked and probably prolonged systemic hypotension. Clinically significant hypotension due to PHARMAMAX AMLODIPINE over- dosage 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.
