Generic Azilsartan (Azilsartan)

Introduction

Azilsartan is an oral antihypertensive medication belonging to the class of angiotensin II receptor blockers (ARBs). It is indicated primarily for the management of high blood pressure in adults. The active compound is azilsartan, supplied in tablet form with common strengths of 40 mg and 12.5 mg. Azilsartan is marketed under brand names such as Edarbi and Azorfar. In addition to its approved use for hypertension, clinical investigations have explored its role in certain cardiovascular and renal conditions, although these applications remain off-label.

What is Azilsartan?

Azilsartan is the generic version of well-known medications, containing the active compound azilsartan. Our online pharmacy provides this generic alternative as a cost-effective treatment option. It is an ARB developed by Takeda Pharmaceuticals and approved by the U.S. Food and Drug Administration (FDA) in 2011. As an ARB, azilsartan blocks the binding of angiotensin II to the AT-1 receptor, thereby reducing vasoconstriction and aldosterone secretion.

How Azilsartan Works

Angiotensin II is a potent vasoconstrictor that increases blood pressure by narrowing blood vessels and stimulating sodium retention. Azilsartan binds selectively to the angiotensin II type 1 (AT-1) receptor on vascular smooth-muscle cells, preventing angiotensin II from exerting its effect. This leads to relaxation of arterial smooth muscle, lower systemic vascular resistance, and reduced blood pressure. The drug reaches peak plasma concentrations within 1.5-3 hours after oral administration and has an elimination half-life of approximately 11 hours, allowing once-daily dosing.

Conditions Treated with Azilsartan

• Essential Hypertension: Azilsartan is approved for the treatment of primary (essential) hypertension. By lowering systemic vascular resistance, it helps achieve target blood-pressure goals and reduces the risk of cardiovascular events.
• Hypertension in Patients with Type 2 Diabetes: Clinical trials demonstrated that azilsartan effectively lowers blood pressure without adversely affecting glycemic control, making it a suitable option for diabetic patients requiring an ARB.

The drug is effective in these conditions because it directly interferes with the renin-angiotensin-aldosterone system (RAAS), a central pathway in blood-pressure regulation.

Off-Label and Investigational Uses of Azilsartan

• Heart Failure with Preserved Ejection Fraction (HFpEF): Small pilot studies have suggested modest improvements in diastolic function when azilsartan is added to standard therapy. Evidence remains limited and the indication is not approved.
• Chronic Kidney Disease (CKD) without Albuminuria: Some investigations have evaluated azilsartan for slowing CKD progression in patients without significant proteinuria. Results are inconclusive, and regulatory approval is lacking.
• Proteinuria Reduction in Nephrotic Syndrome: Case series have reported decreased urinary protein excretion when azilsartan is combined with other RAAS inhibitors. Off-label use should occur only under specialist supervision.

All off-label applications are experimental and must be prescribed only after a thorough risk-benefit assessment by a qualified healthcare provider.

Is Azilsartan the Right Medication for You?

Azilsartan is most appropriate for adults with newly diagnosed or uncontrolled essential hypertension, especially when an ARB is preferred because of renal-protective properties or better tolerability compared with ACE inhibitors. It may be favored in patients who have experienced cough or angio-edema with ACE inhibitors.

Contraindications include:

• Known hypersensitivity to azilsartan or any tablet excipients.
• Severe hepatic impairment (Child-Pugh class C).
• Pregnancy (ARBs are teratogenic) and lactation.

Patients with a history of angio-edema related to previous ARB or ACE-inhibitor therapy should avoid azilsartan.

Risks, Side Effects, and Interactions

Common

• Dizziness or light-headedness: Often related to the blood-pressure-lowering effect, especially after the first dose.
• Headache: Usually mild and transient.
• Fatigue: May occur during dose titration.

Rare

• Elevated serum potassium (hyperkalaemia): More likely in patients with renal impairment or those taking potassium-sparing diuretics.
• Elevated liver enzymes: Occasional transient rise in ALT/AST.

Serious

• Angio-edema: Rapid swelling of the face, lips, tongue, or airway. Requires immediate medical attention.
• Severe hypotension: Particularly in volume-depleted patients (e.g., those on high-dose diuretics).
• Renal failure: Worsening creatinine in patients with pre-existing renal disease.

Drug-Drug Interactions

• Potassium-sparing agents (e.g., spironolactone, amiloride) ↑ risk of hyperkalaemia.
• Non-steroidal anti-inflammatory drugs (NSAIDs): May blunt antihypertensive effect and impair renal function.
• Other RAAS inhibitors (ACE inhibitors, other ARBs): Concomitant use increases risk of hypotension, hyperkalaemia, and renal dysfunction; generally not recommended.

Drug-Food Interactions

• No major food interactions have been identified, but high-salt meals may counteract the antihypertensive effect.

Use: Dosing, Missed Dose, Overdose

• Standard dosing: For most adults, a starting dose of 40 mg once daily is typical. The 12.5 mg strength may be used for patients requiring a lower dose or for dose titration. Dose adjustments are guided by blood-pressure response and tolerability, with a maximum of 80 mg daily in some regions.
• Missed dose: If a dose is missed and the scheduled time for the next 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, and renal impairment. Seek emergency medical care promptly. Supportive treatment focuses on hemodynamic stabilization and monitoring of renal function and electrolytes.
• Administration considerations: Azilsartan tablets may be taken with or without food. Alcohol can exacerbate hypotensive effects; limit consumption. Caution is advised when operating machinery or driving until the individual’s response to the medication is known.

FAQ

• What should I do if I travel abroad with azilsartan? Carry the medication in its original packaging with a copy of the prescription label. Check the destination country’s regulations for ARBs, as some require a physician’s note for import.

• Can azilsartan be taken with a low-sodium diet? Yes. A low-sodium diet complements azilsartan’s blood-pressure-lowering effect and may allow for lower dosing.

• Do azilsartan tablets have any distinguishing markings? Tablets are typically round, light-orange, imprint “AZI 40” or “AZI 12.5” depending on strength. Inactive ingredients commonly include lactose, microcrystalline cellulose, and magnesium stearate.

• Is azilsartan safe for elderly patients? Elderly patients may be more susceptible to hypotension and renal impairment. Initiating therapy at the lower 12.5 mg dose and monitoring renal function is advisable.

• How does azilsartan compare with other ARBs such as losartan? Head-to-head trials have shown that azilsartan provides a greater reduction in systolic blood pressure at comparable doses, likely due to its higher receptor affinity.

• Will azilsartan affect my blood tests for cholesterol? Azilsartan does not directly alter lipid metabolism, so cholesterol levels generally remain unchanged.

• Can I use azilsartan if I have a history of gout? ARBs have a neutral effect on uric acid metabolism, making azilsartan a reasonable choice for patients with gout, provided renal function is stable.

• What is the shelf life of azilsartan tablets? The typical expiration period is 24 months when stored at 20-25 °C (68-77 °F) in a dry environment away from direct sunlight.

• Are there any special disposal instructions? Unused tablets should be returned to a pharmacy take-back program or disposed of according to local hazardous-waste regulations; do not flush them.

• Why might my blood pressure rise after starting azilsartan? Initial “white-coat” effect, poor adherence, high dietary sodium, or interactions with NSAIDs can blunt the antihypertensive response. Follow-up monitoring helps identify and correct these factors.
