Angiotensin II is a potent vasoconstrictor formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme ACE, kininase II. Angiotensin II is the principal pressor agent of the renin-angiotensin system RAS and also stimulates aldosterone synthesis and secretion by adrenal cortex, cardiac contraction, renal resorption of sodium, activity of the sympathetic nervous system, and smooth muscle cell growth. Irbesartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively binding to the AT 1 angiotensin II receptor. There is also an AT 2 receptor in many tissues, but it is not involved in cardiovascular homeostasis.

Although irbesartan may be used to prevent kidney problems or treat people who have kidney problems, it may also rarely cause serious kidney problems or make them worse. Your doctor will check your kidney function while you are taking irbesartan. Tell your doctor right away if you have any signs of kidney problems such as a change in the amount of urine. Irbesartan may be taken with or without food. This product may affect your levels. Before using potassium or salt substitutes that contain potassium, consult your doctor or pharmacist. Usually you replace the lost liquid by drinking fluids and eating foods that contain water. Hydrochlorothiazide: After oral administration of hydrochlorothiazide, diuresis begins within 2 hours, peaks in about 4 hours and lasts about 6 to 12 hours. Angiotensin II receptor antagonists may be used as an alternative for those patients in whom an ACE inhibitor or ARNI is inappropriate. As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals. Use of irbesartan in fixed combination with hydrochlorothiazide is not recommended in patients with severe renal impairment. naproxen
Pholcodine: Blood Pressure Lowering Agents may enhance the hypotensive effect of Pholcodine. When unstented bilateral renal artery stenosis is present, use is generally avoided due to the elevated risk of deterioration in renal function unless possible benefits outweigh risks.

The antihypertensive effects of irbesartan were examined in 7 major placebo controlled 8 to 12 week trials in patients with baseline diastolic blood pressures of 95 mmHg to 110 mmHg. Doses of 1 mg to 900 mg were included in these trials in order to fully explore the dose-range of irbesartan. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.

Impaired renal function, including cases of renal failure in patients at risk, has been reported with irbesartan and Irbesartan and Hydrochlorothiazide. Irbesartan and Hydrochlorothiazide may be administered with or without food. Angioedema: Angioedema has been reported rarely with some angiotensin II receptor antagonists ARBs and may occur at any time during treatment especially following first dose. It may involve the head and neck potentially compromising airway or the intestine presenting with abdominal pain. Patients with idiopathic or hereditary angioedema or previous angioedema associated with ACE-inhibitor therapy may be at an increased risk. Prolonged frequent monitoring may be required, especially if tongue, glottis, or larynx are involved, as they are associated with airway obstruction. Patients with a history of airway surgery may have a higher risk of airway obstruction. Discontinue therapy immediately if angioedema occurs. Aggressive early management is critical. Intramuscular IM administration of epinephrine may be necessary. Do not readminister to patients who have had angioedema with ARBs. zocor
