Generic Avapro Information

Introduction

Avapro (generic name irbesartan) belongs to the class of angiotensin II receptor blockers (ARBs) and is prescribed primarily for the management of high blood pressure (hypertension). In Hong Kong, hypertension affects roughly 30 % of adults, making effective blood‑pressure control a public‑health priority. Avapro is manufactured by Merck & Co. (also known as MSD outside the United States) and is listed under the blood‑pressure medication group by the Hong Kong Department of Health. In addition to hypertension, irbesartan is approved for slowing the progression of diabetic nephropathy in patients with type 2 diabetes and for reducing the risk of stroke in hypertensive patients with left‑ventricular hypertrophy.

What is Avapro?

Avapro is the generic version of Merck’s brand‑name product Avapro, containing the same active compound irbesartan. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. Irbesartan is an oral tablet formulated as a solid‑dose dosage form; it is available in strengths of 75 mg, 150 mg, and 300 mg. The medication is classified as an angiotensin II receptor blocker (ARB) and was first approved by the U.S. Food and Drug Administration (FDA) in 1997. It is marketed worldwide under various brand names, including Avapro (US/Europe) and Aprovel (Brazil).

How Avapro Works

Irbesartan selectively blocks the binding of angiotensin II to the AT1 receptor on vascular smooth‑muscle cells and adrenal tissue. By inhibiting this receptor:

• Vasodilation occurs because the potent vasoconstrictor effect of angiotensin II is removed, lowering systemic vascular resistance.
• Renin‑angiotensin‑aldosterone system (RAAS) activity is reduced, decreasing sodium and water retention, which further lowers blood volume and pressure.

The pharmacokinetic profile shows rapid absorption of irbesartan after oral ingestion, with peak plasma concentrations reached in 1.5–2 hours. The drug has an elimination half‑life of approximately 11–15 hours, supporting once‑daily dosing. Irbesartan is metabolised primarily by the liver (CYP2C9) and excreted unchanged in the feces (~55 %) and urine (~15 %).

Conditions Treated with Avapro

• Essential Hypertension – The primary indication. Clinical trials demonstrated a mean systolic reduction of 12–15 mm Hg and diastolic reduction of 8–10 mm Hg compared with placebo.
• Diabetic Nephropathy (Type 2 Diabetes with Proteinuria) – Irbesartan slows the decline of glomerular filtration rate (GFR) and reduces urinary albumin excretion, reducing the risk of progression to end‑stage renal disease.
• Stroke Risk Reduction in Hypertensive Patients with Left‑Ventricular Hypertrophy – Long‑term data show a modest decrease in first‑stroke incidence when blood pressure is adequately controlled.

In Hong Kong, hypertension prevalence rises with age, and type 2 diabetes affects an estimated 10 % of adults. These epidemiological trends underline the therapeutic relevance of irbesartan for the local population.

Patient Groups Most Likely to Benefit

• Adults with Stage 1–2 Hypertension who have not achieved target blood pressure (<130/80 mm Hg) with lifestyle measures alone.
• Patients with Type 2 Diabetes and Microalbuminuria, where renal protection is a clinical priority.
• Elderly patients who may tolerate ARBs better than ACE inhibitors due to a lower incidence of cough and angio‑edema.
• Individuals with a history of cardiovascular remodeling (e.g., left‑ventricular hypertrophy) where stroke risk reduction is desirable.

Conversely, avapro is not appropriate for:

• Pregnant or breastfeeding women (category D).
• Patients with known hypersensitivity to irbesartan or any ARB component.
• Individuals with severe hepatic impairment (dose adjustment may be required).

Risks, Side Effects, and Interactions

Common

• Dizziness or light‑headedness (often related to postural hypotension)
• Fatigue
• Headache
• Nasopharyngitis

Rare

• Hyperkalemia (elevated serum potassium) – more likely when combined with potassium‑sparing diuretics or supplements.
• Elevated serum creatinine or reduced GFR – monitor renal function after initiation.
• Mild gastrointestinal disturbances (nausea, diarrhoea).

Serious

• Angio‑edema – rare but potentially life‑threatening swelling of the face, lips, tongue, or airway. Immediate medical attention required.
• Severe hypotension – particularly in patients on concurrent antihypertensive therapy or those with volume depletion.
• Acute renal failure – may occur in patients with bilateral renal artery stenosis or severe dehydration.

Clinically Relevant Drug–Drug Interactions

• Potassium‑sparing diuretics (e.g., spironolactone) or potassium supplements → increased risk of hyperkalemia.
• ACE inhibitors (e.g., enalapril) → additive risk of hypotension, hyperkalemia, and renal impairment; concomitant use is generally avoided.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) → may blunt antihypertensive effect and increase renal risk.
• Lithium → ARBs can raise lithium levels, risking toxicity; close monitoring required.
• CYP2C9 inhibitors (e.g., fluconazole) → may modestly increase irbesartan plasma concentrations.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dosing for hypertension: 150 mg once daily. Dose may be titrated to 300 mg once daily based on blood‑pressure response and tolerability.
• Diabetic nephropathy: typically start at 150 mg once daily; the maximum recommended dose is 300 mg daily.
• Renal or hepatic impairment: start at 75 mg once daily; adjust cautiously.

Missed dose: If a dose is forgotten and the next scheduled dose is more than 12 hours away, take the missed tablet as soon as remembered. If the next dose is imminent, skip the missed tablet and resume the regular schedule. Do not double‑dose.

Overdose: Symptoms may include profound hypotension, dizziness, or fainting. Patients should seek emergency medical care‑seeking and inform clinicians that irbesartan has been ingested in excess. No specific antidote exists; treatment is supportive, focusing on blood‑pressure restoration and monitoring renal function.

Precautions:

• Take the tablet with or without food; consistency aids adherence.
• Limit alcohol intake, as excessive consumption can potentiate hypotensive effects.
• Avoid abrupt discontinuation; tapering is not required for ARBs but monitor blood pressure if therapy is stopped.
