In using moexipril hydrochloride tablets, consideration should be given to the fact that another ACE inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen-vascular disease. Available data are insufficient to show that moexipril hydrochloride tablets do not have a similar risk. In considering use of moexipril hydrochloride tablets, it should be noted that in controlled trials ACE inhibitors have an effect on blood pressure that is less in black patients than in non-blacks. In addition, ACE inhibitors cause a higher rate of angioedema in black than in non-black patients.
