Olmesartan Medoxomil/Amlodipine Accord Healthcare (Olmesartan Medoxomil, Amlodipine)

Olmesartan Medoxil/Amlodipine is indicated for hypertension, acting on the renin‑angiotensin system and vascular smooth‑muscle tone.

• Hypertension: improves blood‑pressure control when monotherapy is insufficient.
• Hypertension with isolated systolic elevation: provides additional vasodilation to lower systolic pressure.
• Hypertensive patients at high cardiovascular risk: contributes to reduction of stroke and myocardial‑infarction risk when combined with lifestyle measures.

• Olmesartan medoxil blocks the binding of angiotensin II to the AT1 receptor, preventing vasoconstriction and aldosterone release. Amlodipine inhibits calcium influx into vascular smooth‑muscle cells, causing dose‑dependent arterial dilation. The fixed‑dose combination therefore reduces peripheral resistance and lowers systemic blood pressure through complementary mechanisms.

Adverse reactions may occur with any antihypertensive regimen and should be monitored during therapy.

Common Side Effects

• Dizziness or light‑headedness
• Headache
• Peripheral edema
• Flushing
• Fatigue
• Nasal congestion

Serious or Rare Side Effects

• Angio‑edema involving the face, lips or tongue
• Severe hypotension
• Acute kidney injury
• Elevated liver enzymes
• Heart block or severe bradycardia
• Allergic skin reactions such as Stevens‑Johnson syndrome

Before initiating therapy, clinicians should assess patient history and monitor relevant parameters.

• Renal function: evaluate creatinine clearance before starting and periodically thereafter.
• Hepatic function: check liver enzymes in patients with known liver disease.
• Electrolytes: monitor potassium and sodium levels, especially if combined with diuretics.
• Pregnancy: avoid use; drug is contraindicated in the second and third trimesters.
• Elderly patients: start at lower dose and titrate cautiously.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Olmesartan Medoxil/Amlodipine may interact with several concomitant medicines; clinical judgement is required.

Major Interactions (Avoid)

• Potassium‑rich supplements or potassium‑sparing diuretics: risk of hyper‑kalemia.
• Dual renin‑angiotensin system blockade (e.g., ACE inhibitor or another ARB): increased risk of renal impairment.
• Strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin): may raise amlodipine levels.

Moderate Interactions (Monitor Closely)

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may blunt antihypertensive effect and affect renal function.
• Diuretics: additive blood‑pressure lowering may require dose adjustment.
• Lithium: may increase serum lithium concentrations.
• Alcohol: can enhance dizziness and hypotensive effects.
• Antacids containing aluminium or magnesium: may affect absorption of olmesartan.
