Why is this medication prescribed?
Guanfacine is an oral medication that belongs to the general class of medicines called antihypertensives. It is used to treat high blood pressure (hypertension).
High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Guanfacine works by controlling nerve impulses along certain nerve pathways. As a result, it produces a decrease in sympathetic outflow, resulting in a reduction in peripheral vascular resistance, renal vascular resistance, heart rate, and blood pressure.
Guanfacine is similar to clonidine but is more selective for alpha2-adrenergic receptors, longer acting, dosed once daily, and has less frequency and severity of rebound hypertension following abrupt discontinuation.
