Indications and Usage
Irbesartan and hydrochlorothiazide tablets are indicated for the treatment of hypertension. Irbesartan and hydrochlorothiazide tablets may be used in patients whose blood pressure is not adequately controlled on monotherapy. Irbesartan and hydrochlorothiazide tablets may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals. The choice of irbesartan and hydrochlorothiazide tablets as initial therapy for hypertension should be based on an assessment of potential benefits and risks. Patients with stage 2 (moderate or severe) hypertension are at relatively high risk for cardiovascular events (such as strokes, heart attacks, and heart failure), kidney failure, and vision problems, so prompt treatment is clinically relevant. The decision to use a combination as initial therapy should be individualized and may be shaped by considerations such as the baseline blood pressure, the target goal, and the incremental likelihood of achieving goal with a combination compared with monotherapy. Data from Studies V and VI [see Clinical Studies (14.2)] provide estimates of the probability of reaching a blood pressure goal with irbesartan and hydrochlorothiazide tablets compared to irbesartan or hydrochlorothiazide (HCTZ) monotherapy. The relationship between baseline blood pressure and achievement of a SeSBP <140 or <130 mmHg or SeDBP <90 or <80 mmHg in patients treated with irbesartan and hydrochlorothiazide tablets compared to patients treated with irbesartan or HCTZ monotherapy are shown in Figures 1a through 2b. *For all probability curves, patients without blood pressure measurements at Week 7 (Study VI) and Week 8 (Study V) were counted as not reaching goal (intent-to-treat analysis). The above graphs provide a rough approximation of the likelihood of reaching a targeted blood pressure goal (e.g., Week 8 sitting systolic blood pressure ≤140 mmHg) for the treatment groups.

Because of the hydrochlorothiazide component, this product is contraindicated in patients with anuria or hypersensitivity to other sulfonamide-derived drugs.
