Cilazapril is an angiotensin-converting enzyme inhibitor (ACE inhibitor) used for the treatment of hypertension and congestive heart failure.^[1][2]

It was patented in 1982 and approved for medical use in 1990.^[3]

Of the eight possible stereoisomers, only the all-(S)-form is medically viable.^{[citation needed]}

It is branded as Dynorm, Inhibace, Vascace and many other names in various countries. None of these are available in the United States as of May 2010.^[4]
