Consequently, plasma levels during the early morning hours may have fallen far below the desired or, possibly, urgently needed range. Successful drug therapy in many illnesses is accomplished only if drug concentration is maintained at a steady high level.
Accordingly, diazoxide can be used in the management of insulin-secreting pancreatic tumors. Both effects are probably due to opening of (ATPgated) K+ channels. The methylxanthine theophylline, the phosphodiesterase inhibitor amrinone, prostacyclins, and nicotinic acid derivatives also possess vasodilating activity.

 

Trazodone is an antidepressant medication. It is thought to increase the activity of one of the brain chemicals (serotonin) which may become unbalanced and cause depression.

It typically corresponds to the inflection point of the concentration– response curve in a semilogarithmic plot (log concentration on abscissa).
