Current hypertension guidelines suggest various strategies to reduce blood pressure levels, thereby reducing cardiovascular events: combinations of drugs with different mechanisms of action, such as an angiotensin converting enzyme inhibitors (ACEIs) and a diuretic, are the cornerstone of the modern treatment of hypertension, also as initial therapy. Among ACEIs, zofenopril has been shown to be effective in the management of hypertension both as monotherapy and in combination with a diuretic: zofenopril/hydrochlorothiazide fixed dose combination is particularly useful to improve treatment adherence through simplification of treatment regimen. Moreover, thanks to the sulfhydryl group, zofenopril has some peculiar properties (higher lipophilicity and tissue penetration, lower bradykinin-dependent effect, higher affinity for, and more persistent binding to, tissue ACE, significant antioxidant effect), which may account for the cardioprotective effects of the drug demonstrated in both pre-clinical studies and randomized clinical trials. The positive impact of zofenopril on clinical outcomes has been extensively documented by the SMILE program, including several clinical trials in patients with different conditions of myocardial ischemia treated with zofenopril: the results of the SMILE program, demonstrating the benefits of zofenopril vs. placebo and other ACEIs, emphasize the importance of a differentiated approach to patients with ischemic heart disease, based on a careful choice of the adopted agent, in order to improve the overall impact of pharmacological treatment on clinical outcomes.
