Hyperium is a drug used primarily to treat high blood pressure. This drug works by affecting the central nervous system, where it activates certain receptors known as imidazoline receptors, which leads to regulating the activity of the sympathetic nervous system. This effect results in a decrease in heart rate and dilation of blood vessels, thus improving blood flow and reducing pressure in the arteries. Hyperium is a suitable option for some patients who may have difficulty tolerating other medications used for this purpose, such as beta-blockers or angiotensin-converting enzyme inhibitors.
