Study Summary: This study investigates a drug called Iloperidone to see if it helps people with high blood pressure (also called hypertension) that hasn't improved with other treatments. It's a special type of study to ensure accuracy, meaning neither the participants nor the doctors know who gets the real medicine or a fake one (placebo). The goal is to check if Iloperidone is safe and effective.

Key Points:

• The study includes people with blood pressure of 130 mmHg or higher, even after 8 weeks of other treatments.
• People cannot join if their blood pressure is extremely high (180/120 mmHg or more) or if they have severe heart or kidney issues.
• Participants will need to visit multiple centers for testing and check-ups.

Note: It's important to talk to your doctor about joining, as they can help decide if it's a good option for you.
