Avapro is typically taken as an oral tablet. The exact dosage depends on the condition being treated, the patient’s age, and their overall health. It is essential to follow the doctor’s instructions and take the medication as prescribed.
Hypertension: For adults, the usual starting dose is 150 mg per day. Dose titration should be titrated up to a maximum dose of 300 mg daily based on the patient’s response. Lower doses for elderly patients or for patients with liver disorders may be initiated with a dosage of 75 mg.
Diabetic Nephropathy: For diabetic nephropathy in patients with type 2 diabetes, the recommended initial dosing is 150 mg once daily. The dose can be titrated based on patient response; however, the maximum recommended daily dose is 300 mg.
Mechanism of action Avapro blocks the angiotensin II receptor type 1 with critical engagement in regulating blood pressure and fluid balance in the body. Angiotensin II is a potent vasoconstrictor that narrows the blood vessels, causing a rise in blood pressure.
It stimulates the release of aldosterone, a hormone that impels the kidneys to retain sodium and water, yet further elevates blood pressure.
Avapro prevents the vasoconstrictive and aldosterone-promoting effects of angiotensin II by blocking the AT1 receptor. This causes dilation and lowering of blood pressure as the blood vessels relax and become broader.
Through this action, Avapro also reduces the load of the heart, thereby preventing the further progression of kidney disease within diabetic patients as high blood pressure and proteinuria are reduced.
Avapro is generally well tolerated, but like any medication, it may cause side effects in some patients. Common side effects include:
Dizziness or light-headedness: These often occur when standing up quickly from sitting or lying down, especially on initiation of the drug.
Fatigue: Some people will feel markedly tired or weak
Headache: Mild to moderate headache sometimes occurs as a side effect.
Hyperkalemia (high blood potassium level): Avapro is rarely associated with high levels of potassium in the blood, which can trigger irregular heart rhythm and other complications.
Gastrointestinal symptoms: Nausea and vomiting, as well as diarrhea, are possible occasionally.
Pregnancy: Avapro should not be used during pregnancy, particularly in the second and third trimesters, as it can harm the fetus. Women who are pregnant or planning to become pregnant should consult their healthcare provider before starting the medication.
Liver or Kidney Problems : Patients with liver or kidney problems should exercise caution when using Avapro. The dosage may have to be altered, and there must be regular monitoring of kidney function.
Electrolyte Imbalances: Potassium levels must be observed closely, as Avapro may raise blood potassium and cause severe complications.
Angioedema: Dizziness – Swelling of the face, lips, or tongue – Sudden severe swelling. If these symptoms occur, stop taking Avapro, and seek emergency medical attention.
Hypertension (High Blood Pressure):
Starting 150 mg daily
Maintenance: 150–300 mg a day
Diabetic Nephropathy:
Starting 150 mg daily
Maintenance: 150–300 mg a day
The dose should be individualized according to the patient’s primary medical condition, treatment response, and concomitant illnesses. Blood pressure and renal function should be observed periodically in the course of treatment.
Avapro is available only with a doctor’s prescription. Prior to issuing the prescription, the doctor will discuss the patient’s entire medical history with the patient, including any kidney or liver problems, other medications taken by the patient, and potential drug interactions.
Especially important to disclose on a patient history are allergies, especially to other blood pressure medications such as ACE inhibitors.
The patient should also inform his doctor if he or she is pregnant, in planning to become pregnant, or breastfeeding, since Avapro is contraindicated during pregnancy.
