Many devices are based on hydrostatics such as barometers and manometers, i.e., determine pressure through measurement of a column (or columns) of a liquid using the pressure variation with elevation equation for an incompressible fluid.
Tenex is the brand-name version of a generic drug called guanfacine. This drug is typically prescribed to treat high blood pressure. Itâs not approved by the Food and Drug Administration (FDA) to treat ADHD. However, your childâs doctor may still prescribe Tenex to treat ADHD.
What is Tenex (guanfacine)? Guanfacine reduces nerve impulses in your heart and blood vessels. Guanfacine works by relaxing blood vessels, which lowers blood pressure and improves blood flow. Guanfacine is used to treat high blood pressure (hypertension). It is sometimes given together with other blood pressure medications. Guanfacine is also used to treat attention deficit hyperactivity disorder (ADHD) in children who are at least 6 years old.
