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.
Tenex is used alone or in combination with other medications for the treatment of hypertension (high blood pressure). Guanfacine reduces blood pressure by reducing the resistance of blood flow in the blood vessels, and by decreasing heart rate. Intuniv (guanfacine extended release) is used alone or in combination with other medications for the treatment of attention deficit hyperactivity disorder (ADHD).
