Efficacy and Side Effects of Irbesartan Tablets

Irbesartan tablets are a commonly used antihypertensive medication in clinical practice, indicated for the treatment of essential hypertension and for hypertensive patients with type 2 diabetic nephropathy. The active pharmaceutical ingredient is irbesartan. So, what are the therapeutic effects and adverse reactions of irbesartan tablets? Below, we provide a detailed explanation.

Therapeutic Effects of Irbesartan Tablets

Irbesartan tablets belong to the class of angiotensin II receptor blockers (ARBs). They exert antihypertensive effects by inhibiting vasoconstriction and aldosterone release. Since hypertension requires long-term pharmacological management and is generally not curable, patients must adhere strictly to their physician’s instructions regarding continuous therapy and must not discontinue the drug without medical guidance—otherwise, poor blood pressure control may lead to serious complications such as intracerebral hemorrhage. For hypertensive patients who are also obese, regular physical activity and weight management are recommended, as these measures significantly aid in blood pressure control.

In patients with hypertension secondary to diabetic nephropathy, irbesartan helps mitigate renal damage. This benefit arises from its ability to reduce glomerular filtration of protein and thereby decrease proteinuria. Additionally, irbesartan is indicated for heart failure management, prevention of left ventricular remodeling, delay of heart failure symptom progression, stroke prevention (particularly cerebral thrombosis), and maintenance of sinus rhythm following cardioversion in patients with atrial fibrillation.

Adverse Reactions of Irbesartan Tablets

Adverse reactions may occur during treatment. The most common include dizziness, vertigo, palpitations, and occasional cough—typically mild in severity. Most patients can continue therapy and tolerate these symptoms. Hypersensitivity reactions may manifest as pruritus, erythema, rash, or urticaria-like skin changes; severe cases may involve angioedema.

Gastrointestinal symptoms may include dyspepsia, heartburn, acid reflux, abdominal pain, diarrhea, and abdominal distension. Musculoskeletal adverse effects may include myalgia and fatigue. Upper respiratory tract infections may also occur. Less commonly, patients may experience anxiety, nervousness, chest pain, pharyngitis, tachycardia, hypotension, or orthostatic hypotension. Irbesartan is contraindicated in patients with known hypersensitivity to the drug, as well as in pregnant and breastfeeding women.

The above outlines the therapeutic effects and adverse reactions associated with irbesartan tablets. We hope this information proves helpful.
