Avapro (irbesartan) is an angiotensin II receptor blocker (ARB) prescribed for the management of hypertension and nephropathy in type 2 diabetic patients. It works by blocking the action of certain natural substances that tighten blood vessels, allowing blood to flow more smoothly and the heart to pump more efficiently. This medication is trusted by healthcare professionals worldwide for its efficacy in reducing high blood pressure and helping to protect kidney function. Clinical studies support its role in decreasing the risk of stroke, heart attack, and kidney problems in at-risk populations. Avapro offers a well-tolerated treatment option with a once-daily dosing regimen for consistent 24-hour coverage.

Common use

Avapro is primarily indicated for the treatment of hypertension, either as monotherapy or in combination with other antihypertensive agents. It is also used for renal protection in patients with type 2 diabetes mellitus and hypertension, demonstrated to reduce the rate of progression of nephropathy as evidenced by persistent albuminuria. Off-label uses may include heart failure management when other treatments are not suitable, though this should only be under specialist supervision.

Dosage and direction

The recommended initial dose of Avapro for hypertension is 150 mg once daily. The dosage may be increased to 300 mg once daily if blood pressure is not adequately controlled. For volume-depleted patients, consider starting with 75 mg once daily. For nephropathy in type 2 diabetic patients, the recommended maintenance dose is 300 mg once daily. Tablets may be taken with or without food. Avapro should be taken at approximately the same time each day to maintain consistent blood levels. Dosage adjustments may be necessary for elderly patients or those with renal impairment.

Precautions

Before taking Avapro, inform your healthcare provider if you have kidney disease, liver disease, heart conditions, or are on a salt-restricted diet. Avoid use during pregnancy as it can cause injury or death to the unborn baby. Patients should be monitored for hypotension, especially after the initial dose or following dosage increases. Regular assessment of renal function and serum potassium levels is recommended, particularly in patients with renal impairment or those taking potassium supplements. Dehydration may increase the risk of hypotension; maintain adequate fluid intake unless otherwise directed.

Contraindications

Avapro is contraindicated in patients with known hypersensitivity to irbesartan or any component of the formulation. Do not use with aliskiren in patients with diabetes. Contraindicated in patients with a history of angioedema related to previous treatment with an ARB. Avoid use during the second and third trimesters of pregnancy. Not recommended for patients with severe hepatic impairment or biliary obstruction.

Possible side effects

Common side effects may include dizziness, lightheadedness, or upset stomach. These effects often diminish as your body adjusts to the medication. Less common but more serious side effects may include:

• Symptoms of high potassium levels (muscle weakness, slow/irregular heartbeat)
• Signs of kidney problems (change in amount of urine, swelling in feet/ankles)
• Severe dizziness, fainting
• Signs of infection (fever, chills, persistent sore throat)
• Allergic reactions (rash, itching/swelling especially of face/tongue/throat, severe dizziness, trouble breathing)

Drug interaction

Avapro may interact with several medications including:

• Other blood pressure medications (may increase risk of low blood pressure)
• Potassium supplements or potassium-sparing diuretics (increased risk of hyperkalemia)
• NSAIDs (may reduce antihypertensive effect and increase risk of renal impairment)
• Lithium (may increase lithium levels)
• Aliskiren (particularly in diabetic patients)
• Certain diabetes medications Always inform your healthcare provider of all medications you are taking, including prescription, over-the-counter, and herbal products.

Missed dose

If you miss a dose of Avapro, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose to catch up. Consistent daily administration is important for maintaining blood pressure control.

Overdose

Symptoms of overdose may include severe dizziness, fainting, or unusually fast or slow heartbeat. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and symptomatic; hypotension should be treated with intravenous normal saline. Avapro is not significantly removed by hemodialysis.

Storage

Store Avapro tablets at room temperature (15-30°C or 59-86°F) in their original container. Keep away from moisture, light, and heat. Do not store in the bathroom. Keep all medications away from children and pets. Properly discard any expired or unused medication according to local guidelines.

Reviews

Clinical studies demonstrate that Avapro effectively reduces blood pressure in 70-80% of patients, with significant reductions in both systolic and diastolic measurements. In the IRMA 2 trial, Avapro 300 mg reduced the relative risk of diabetic nephropathy by 70% compared to placebo. Patient satisfaction surveys indicate high adherence rates due to once-daily dosing and generally favorable side effect profile. Many users report improved quality of life with effective blood pressure control without significant side effects. Healthcare professionals appreciate its predictable pharmacokinetics and reliable 24-hour coverage.
