Irbesartan is an oral pill belonging to the Heart & Blood Pressure therapeutic class. It is an angiotensin II receptor blocker (ARB) that helps lower high blood pressure and protect the kidneys in certain patients with diabetes. In the United Kingdom, irbesartan is a prescription-only medication regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). It is marketed in two strengths: 150 mg and 300 mg tablets.
Irbesartan selectively blocks the binding of angiotensin II to the AT₁ receptor found on blood-vessel smooth muscle and adrenal tissue. By preventing this interaction, the drug:
The onset of blood-pressure reduction typically occurs within 1-2 hours after a dose, with peak effect around 2 hours. The drug’s half-life is about 12 hours, allowing once-daily dosing. Irbesartan is well absorbed from the gastrointestinal tract, with an oral bioavailability of roughly 60 %.
The medication is intended for adult patients; pediatric use is not established.
