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.Figure 1a: Probability of Achieving SBP < 140 mmHg in Patients From Initial Therapy Studies V (Week 8) and VI (Week 7)Figure 1b: Probability of Achieving SBP < 130 mmHg in Patients From Initial Therapy Studies V (Week 8) and VI (Week 7)Figure 2a: Probability of Achieving DBP < 90 mmHg in Patients From Initial Therapy Studies V (Week 8) and VI (Week 7)Figure 2b: Probability of Achieving DBP < 80 mmHg in Patients From Initial Therapy Studies V (Week 8) and VI (Week 7)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.

No dosage adjustment is necessary in patients with hepatic impairment.In patients not controlled on monotherapy with irbesartan or hydrochlorothiazide, the recommended doses of irbesartan and hydrochlorothiazide tablets USP, in order of increasing mean effect, are (irbesartan-hydrochlorothiazide) 150/12.5 mg, 300/12.5 mg, and 300/25 mg. The largest incremental effect will likely be in the transition from monotherapy to 150/12.5 mg. [See Clinical Studies (14.2). It is a nonpolar compound with a partition coefficient (octanol/water) of 10.1 at pH of 7.4. The largest incremental effect will likely be in the transition from monotherapy to 150/12.5 mg.

The side effects of irbesartan are generally rare and apparently independent of dose; those of hydrochlorothiazide are a mixture of dose-dependent (primarily hypokalemia) and dose-independent phenomena (e.g., pancreatitis), the former much more common than the latter.
