Olmesartán Teva (Olmesartan Medoxomil)

Olmesartan medoxyl is used to manage conditions that involve the renin‑angiotensin system.

• Hypertension: lowers systolic and diastolic blood pressure, reducing cardiovascular risk.
• Diabetic nephropathy: slows progression of kidney damage in type 2 diabetes.
• Heart failure prevention: assists in preventing heart‑failure related events in high‑risk patients.

• Olmesartan medoxyl is a selective antagonist of the angiotensin II type 1 (AT1) receptor. By blocking this receptor, it prevents angiotensin II‑mediated vasoconstriction and aldosterone release, leading to vasodilation, reduced sodium and water retention, and ultimately lower blood pressure.

Olmesartan medoxyl may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

• Dizziness
• Headache
• Fatigue
• Nasal congestion
• Diarrhea
• Upper respiratory tract infection

Serious or Rare Side Effects

• Angio‑ema
• Hyperkalemia
• Acute kidney injury
• Severe hypotension
• Liver enzyme elevation
• Bullous skin reactions

When prescribing Olmesartan medoxyl, clinicians should consider several safety aspects.

• Monitor blood pressure: ensure adequate control without excessive lowering.
• Assess renal function: check creatinine and electrolytes before initiation and periodically.
• Review potassium levels: hyper‑kalaemia risk requires monitoring, especially with potassium‑sparing diuretics.
• Avoid in pregnancy: drug is contraindicated during the first trimester.
• Caution in elderly: start with lower dose and monitor for orthostatic symptoms.
• Store at below 25°C: keep in the original packaging, protect from moisture and light.

Olmesartan medoxyl can interact with several medicines that affect blood pressure, electrolytes, or renal function.

Major Interactions (Avoid)

• Aliskiren combined with oligo‑conception? (…)
