Generic Irbesartan Information

Introduction

Irbesartan is an oral antihypertensive medication classified as an angiotensin II receptor blocker (ARB). It is widely prescribed in the United Kingdom for the management of high blood pressure and for slowing the progression of diabetic kidney disease. The active compound is Irbesartan, and the drug belongs to the blood‑pressure therapeutic group. Although the molecule was originally marketed under the brand name Avapro, generic Irbesartan provides the same clinical benefit at a lower cost, making it an important option for patients and healthcare systems.

What is Irbesartan?

Irbesartan is a synthetic molecule that selectively blocks the type 1 angiotensin II receptor (AT₁). The drug was developed by the pharmaceutical company Sanofi‑Aventis and first approved in the United States in 1997. In the United Kingdom, it is available as a prescription‑only medicine in tablet form.

Irbesartan is the generic version of Avapro, containing the same active compound Irbesartan. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Irbesartan Works

Angiotensin II is a peptide hormone that constricts blood vessels and stimulates aldosterone secretion, leading to increased blood pressure and fluid retention. Irbesartan binds with high affinity to AT₁ receptors on vascular smooth muscle and adrenal tissue, preventing angiotensin II from exerting its effects.

• Vasodilation: Blocking AT₁ receptors relaxes arterial smooth muscle, reducing peripheral resistance.
• Reduced sodium and water reabsorption: Inhibition of aldosterone release decreases renal sodium retention, lowering circulating blood volume.

The antihypertensive effect typically appears within 2 hours of ingestion, reaches a plateau after 2–4 weeks of consistent therapy, and is maintained as long as the drug is taken daily. Irbesartan is eliminated primarily via hepatic metabolism (CYP2C9) and renal excretion, with a half‑life of approximately 11‑15 hours, supporting once‑daily dosing.

Conditions Treated with Irbesartan

• Essential (primary) hypertension: High prevalence in the UK (≈1.2 million adults on antihypertensive therapy) makes effective blood‑pressure control a public‑health priority. Irbesartan lowers systolic and diastolic pressures, reducing the risk of stroke and myocardial infarction.
• Diabetic nephropathy (type 2 diabetes with albuminuria): Clinical trials (e.g., the IRMA‑2 study) demonstrated that Irbesartan slows the decline in glomerular filtration rate and reduces urinary albumin excretion, protecting kidney function.
• Proteinuric chronic kidney disease: Irbesartan is indicated for non‑diabetic renal disease with proteinuria, where lowering intraglomerular pressure confers renal benefit.

All indications are approved by the Medicines and Healthcare products Regulatory Agency (MHRA) for use in the United Kingdom.

Who is Irbesartan For?

Irbesartan is appropriate for adult patients who:

• Have been diagnosed with stage 1 or stage 2 essential hypertension and require an ARB either as monotherapy or in combination with other antihypertensives.
• Have type 2 diabetes with persistent micro‑ or macro‑albuminuria and an estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m².
• Present with proteinuric chronic kidney disease where ACE inhibitors are not tolerated or contraindicated.

Contra‑indications or cautionary use include:

• Known hypersensitivity to Irbesartan or any ARB.
• Pregnancy (especially the second and third trimesters) due to risk of fetal renal toxicity.
• Severe hepatic impairment (dose adjustment may be required).
• Concomitant use with aliskiren in patients with diabetes or moderate to severe renal impairment.

Physicians may avoid Irbesartan in patients with a history of angio‑edema related to previous ACE‑inhibitor or ARB therapy.

Risks, Side Effects, and Interactions

Common

• Dizziness, especially after the first dose or when standing up quickly (orthostatic hypotension).
• Headache.
• Fatigue.
• Nasopharyngitis (common cold‑like symptoms).

Rare

• Hyperkalemia (elevated blood potassium).
• Elevated serum creatinine or reduced eGFR indicating renal function change.
• Mild liver enzyme elevation (ALT, AST).

Serious

• Angio‑edema of the face, lips, tongue or throat, which can compromise airway.
• Severe hypotension leading to syncope.
• Acute renal failure, particularly when combined with diuretics, NSAIDs, or in volume‑depleted patients.

Drug–drug interactions

• Potassium‑sparing diuretics, supplements, or salts: increase risk of hyperkalaemia.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): may blunt antihypertensive effect and worsen renal function.
• Lithium: concomitant use can raise lithium levels, risking toxicity.
• CYP2C9 inhibitors (e.g., fluconazole, amiodarone): may increase Irbesartan plasma concentrations; dose adjustment may be needed.

Patients should inform their healthcare professional of all medicines, including over‑the‑counter products and herbal supplements.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for hypertension: 150 mg once daily; may be increased to 300 mg based on blood‑pressure response.
• Diabetic nephropathy or proteinuric kidney disease: start at 150 mg once daily; titrate to 300 mg if tolerated and if renal function permits.
• Renal impairment (eGFR 30‑60 mL/min/1.73 m²): initial dose 75 mg daily, with careful monitoring of renal parameters and potassium.

Missed dose: Take the missed tablet as soon as remembered on the same day. If it is close to the time of the next scheduled dose, skip the missed tablet and resume the regular schedule. Do not double‑dose.

Overdose: Symptoms may include severe hypotension, dizziness, or fainting. Seek immediate medical attention; supportive care (e.g., intravenous fluids, blood‑pressure monitoring) is the mainstay of treatment.

Precautions:

• Take Irbesartan with or without food; consistency aids adherence.
• Limit alcohol intake, as it can exacerbate hypotensive effects.
• Avoid abrupt discontinuation; tapering under medical supervision reduces rebound hypertension risk.

FAQ

• Is Irbesartan available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is Avapro, while generic Irbesartan contains the identical active ingredient and is typically less expensive.

• What should I do with Irbesartan tablets if I travel abroad?
  Keep tablets in their original packaging, store them at room temperature away from moisture, and carry a copy of the prescription or a doctor’s note to satisfy customs authorities if requested.

• Does Irbesartan require any special storage conditions?
  No refrigeration is needed. Store the tablets at a temperature between 15 °C and 30 °C, protected from light, heat, and humidity.

• Will Irbesartan interact with over‑the‑counter herbal supplements?
  Certain herbs, such as licorice root, can increase blood‑pressure effects and may counteract Irbesartan. Always discuss any supplements with your healthcare provider.

• Are there regional differences in the tablet formulation of Irbesartan?
  Formulations sold in the EU, including the UK, typically contain the same inert ingredients (e.g., lactose, maize starch). Some Asian markets may use alternative fillers; however, the active dose remains consistent.

• Can Irbesartan be detected in standard drug‑testing panels?
  Irbesartan is not a controlled substance and is not screened for in routine occupational or sports drug‑testing programs.

• What clinical trial first demonstrated Irbesartan’s renal benefits?
  The IRMA‑2 (Irbesartan Diabetic Nephropathy) study, published in The Lancet (1999), showed significant reductions in urinary albumin excretion and slower decline of renal function in type 2 diabetic patients.

• How does Irbesartan compare with the older drug losartan?
  Both are ARBs, but Irbesartan generally provides a slightly greater reduction in blood pressure at equivalent doses and has stronger evidence for renal protection in diabetic nephropathy.

• Is it safe to take Irbesartan with a low‑sodium diet?
  A low‑sodium diet complements the blood‑pressure‑lowering effect of Irbesartan and is often recommended to enhance therapeutic outcomes.

• What is the legal basis for importing Irbesartan personally into the UK?
  Under UK law, individuals may import a three‑month supply of prescription medicines for personal use, provided they hold a valid prescription and the product is not classified as a controlled drug.
