Descriptive Information
Brief Title  ICMJE Irbesartan/Hydrochlorothiazide (HCTZ) Combination Therapy as First Line Treatment for Severe Hypertension
Official Title  ICMJE The Efficacy and Safety of Irbesartan/HCTZ Combination Therapy as First Line Treatment for Severe Hypertension
Brief Summary The purpose of this clinical research is to learn if severe hypertension can be better controlled by initially treating with a combination of drugs (Irbesartan/HCTZ), in patients who are unlikely to achieve blood pressure (B/P) control with only one drug. In addition, the study will also evaluate the safety and tolerability of the drugs.

Exclusion Criteria:

  • Women who are pregnant or breastfeeding;
  • Known or suspected secondary hypertension;
  • Hypertension emergencies or stroke within the past 12 months;
