Amlodipine + Olmesartan Medoxomil

Indications

Amlodipine & Olmesartan is indicated for the treatment of hypertension, alone or with other antihypertensive agents. This may also be used as initial therapy in patients who are likely to need multiple antihypertensive agents to achieve their blood pressure goals.

Therapeutic Class

Combined antihypertensive preparations

Pharmacology

Amlodipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle & cardiac muscle. Amlodipine is a peripheral arterial vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance & a reduction in blood pressure.

Olmesartan is an angiotensin II receptor blocker that acts on AT1 subtype. By blocking the action of angiotensin II, Olmesartan dilates blood vessels and reduces blood pressure without affecting pulse rate.

Dosage & Administration

Initial Therapy: The usual starting dose of Amlodipine & Olmesartanis one tablet (5/20 mg) once daily. Thedosage can be increased after 1 to 2 weeks of therapy to a maximum dose is two tablets (10/40 mg) once daily as needed to control bloodpressure. This may be taken with or without food and may beadministered with other antihypertensive agents.Initial therapy with this combination product is not recommended in patients ≥75 years old or with hepatic impairment.

Replacement Therapy: Amlodipine & Olmesartanmay be substituted for its individually titrated components. Whensubstituting for individual components, the dose of one or both of the components can be increased if blood pressure control has not been satisfactory.

Patients with Hepatic Impairment: Caution should be exercised when administering the drug to patients with severe hepatic impairment.

Overdose Effects

There is no experience of overdose with Amlodipine & Olmesartan combination. The most likely effects of olmesartan medoxomil overdosage are hypotension and tachycardia; bradycardia could be encountered if parasympathetic (vagal) stimulation occurred.

Amlodipine overdosage can be expected to lead to excessive peripheral vasodilatation with marked hypotension and possibly a reflex tachycardia. Marked and potentially prolonged systemic hypotension up to and including shock with fatal outcome has been reported.

Use in Special Population

The safety and effectiveness in pediatric patients have not been established.
