Zofenopril Calcium

Angiotensin-converting enzyme inhibitors (ACEIs) reduce arterial stiffness beyond their antihypertensive effect. Studies showed that sulfhydryl ACEIs have the antioxidative potential to improve endothelial function, which might have a clinical effect on arterial distensibility. However, there are no studies that directly compare the effects of sulfhydryl (zofenopril) and non-sulfhydryl ACEIs (enalapril) on arterial stiffness. Therefore, this prospective study aims to compare the effects of enalapril and zofenopril on arterial stiffness and oxidative stress in both short- and long-term treatment of arterial hypertension (AH). Baseline and post-treatment peripheral and central arterial pressure indices, augmentation index (Aix), aortic pulse wave velocity (ao-PWV), serum levels of oxidized low-density cholesterol lipoprotein, LDL and uric acid (UA) were measured. The results showed that acute treatment with zofenopril, in contrast to enalapril, significantly decreased peripheral and central Aix (p < 0.001). Chronic treatment with zofenopril showed a superior effect over enalapril on the reduction of the peripheral systolic arterial pressure with reduction of ao-PWV (p = 0.004), as well as a reduction in peripheral Aix (p = 0.021) and central Aix (p = 0.021). Therefore, this study indicates that zofenopril has beneficial effects on the reduction of arterial stiffness compared to enalapril. It has potent clinical efficacy in AH treatment and further studies should compare its safety and long-term efficacy to other AH drugs that would aid clinicians in treating AH and other various cardiovascular diseases that have arterial stiffness as a common denominator.

Clinically describing hypertensive patients initiating nebivolol/zofenopril extemporaneous combination (NZ-EXC) and estimating the number of patients currently receiving NZ-EXC and of those potentially eligible for the fixed-dose combination of the two molecules (NZ-FDC) in Italy.

This retrospective observational study used data from IQVIA Italian Longitudinal Patient Database (LPD). Adult hypertensive patients firstly prescribed NZ-EXC between 1 July 2011 and 30 June 2020 were identified and their demographic and clinical characteristics were extracted. Treatment adherence was evaluated as proportion of days covered (PDC) and classified as low (PDC <40%), intermediate (PDC ≥40% and <80%) or high (PDC ≥80%). Two additional cohorts were identified in 2019 to provide the national-level yearly estimates of patients prescribed NZ-EXC and of patients eligible for NZ-FDC.

In total 1745 patients were prescribed NZ-EXC: 60% were women; mean age was 65 years. The most frequent comorbidities were dyslipidemia (19.0%), diabetes (15.5%) and thyroid diseases (13.1%); the most common co-prescribed treatments were antithrombotics (29.1%), lipid-lowering agents (28.8%), nonsteroidal anti-inflammatory drugs (26.1%) and antihyperglycemic agents (13.5%). Mean PDC was 39%, and 57% of the patients had a PDC < 40%. The yearly estimate of patients prescribed NZ-EXC in 2019 was 59,000, while potential users of NZ-FDC were estimated to be 29,000.

NZ-EXC in hypertensive patients is a common practice in Italy and the development of a NZ-FDC can be a viable treatment option for hypertensive patients who are already receiving nebivolol and zofenopril through the concomitant assumption of two distinct pills. As supported by scientific literature, FDCs of antihypertensive drugs could simplify treatment, improve adherence and potentially reduce health-care costs as related to a better control of blood pressure.
