This review summarizes the evidence indicating that local synthesis of angiotensin II, and interference with this process by inhibition of angiotensin-converting enzyme (ACE), may be important in the treatment of hypertension. Inhibition of tissue converting enzyme generally has a stronger correlation with the hemodynamic effects of ACE inhibitors than inhibition of ACE in plasma. Reported differences in the ability of ACE inhibitors to penetrate tissues and to bind to the converting enzyme may be closely related to the relative lipophilicity of these agents. Finally, correlation of data from clinical studies with results provided by laboratory experimentation suggests that the efficacy of different ACE inhibitors in hypertensive patients may be predicted from differences among the actions of these drugs in vitro and in whole animals.
