Olmesartan E Amlodipina Aurobindo (Olmesartan Medoxomil, Amlodipine)

Olmesartan / amlodipine is used to manage high blood pressure by targeting the renin‑angiotensin system and vascular smooth‑muscle tone.

• Hypertension: lowers systolic and diastolic blood pressure to reduce cardiovascular risk.
• Chronic kidney disease with hypertension: provides renal protection by controlling blood pressure.
• Heart failure with reduced ejection fraction (as adjunct therapy): assists in afterload reduction when combined with standard heart‑failure regimens.
• Post‑myocardial infarction hypertension: helps maintain target blood pressure after an acute coronary event.
• Elderly patients with isolated systolic hypertension: offers effective blood‑pressure control with a favorable tolerability profile.

• Olmesartan medoxil selectively blocks the angiotensin II type 1 (AT1) receptor, preventing angiotensin II‑mediated vasoconstriction and aldosterone release. Amlodipine, a dihydropyridine calcium‑channel blocker, inhibits calcium influx into vascular smooth‑muscle cells, causing arterial dilation. The combined effect reduces peripheral vascular resistance and lowers blood pressure without significant impact on heart rate.

Common Side Effects

• Headache: mild to moderate intensity.
• Peripheral edema: swelling of ankles or feet.
• Dizziness or light‑headedness: especially after the first doses.
• Flushing: transient warmth sensation.
• Fatigue: general tiredness.
• Palpitations: awareness of heartbeat.

Serious or Rare Side Effects

• Angio‑edema: rapid swelling of face, lips, tongue, or airway.
• Severe hypotension: symptomatic low blood pressure.
• Hepatic dysfunction: elevated liver enzymes or jaundice.
• Acute kidney injury: sudden decline in renal function.
• Myocardial infarction: rare occurrence of heart attack.
• Blood dyscrasias: neutropenia or thrombocytopenia.

When using Olmesartan / amlodipine, consider the following precautions:

• Pregnancy: contraindicated; risk of fetal toxicity.
• Breastfeeding: not recommended; potential excretion in milk.
• Renal impairment: dose adjustment may be required; monitor kidney function.
• Hepatic impairment: use with caution; monitor liver enzymes.
• Electrolyte imbalance: watch for potassium abnormalities.
• Drug‑induced hypotension: avoid abrupt posture changes.
• Store at ambient temperature: keep below 25 °C, protect from moisture and light.

Olmesartan / amlodipine may interact with several medicines. Review the following groups:

Major Interactions (Avoid)

• Dual renin‑angiotensin system blockade (e.g., ACE inhibitors, other ARBs): increased risk of hyperkalaemia and renal dysfunction.
• Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): elevated amlodipine levels.

Moderate Interactions (Monitor Closely)

• Diuretics: additive blood‑pressure lowering effect, may cause hypotension.
• NSAIDs: may blunt antihypertensive response and affect renal function.
• Lithium: increased lithium levels, risk of toxicity.
• Simvastatin: amlodipine raises simvastatin concentrations, risk of myopathy.
• Alcohol: may enhance dizziness and hypotensive effects.
