Which medication is known as Tenex and is indicated for hypertension?

Guanfacine, marketed under the brand name Tenex, is indicated for the treatment of hypertension. This medication belongs to a class of drugs known as alpha-2 adrenergic agonists, which work in the central nervous system to lower blood pressure by decreasing peripheral vascular resistance and reducing heart rate. Guanfacine helps to provide better control over blood pressure levels.

In this context, it's essential to differentiate guanfacine from other medications. Clonidine ER, while also an alpha-2 agonist used for hypertension, is not marketed as Tenex. Methyldopa is another antihypertensive agent but is a different medication altogether and primarily used in pregnancy. Minoxidil, on the other hand, is a vasodilator primarily used for refractory hypertension and is also known for its use in treating hair loss, making it not applicable for this question regarding Tenex. Thus, guanfacine stands out as the correct answer in this scenario.
