Abstract
OBJECTIVES
To provide clinical characteristics and to quantify the number of patients receiving the extemporaneous combination of the calcium channel blocker amlodipine and the angiotensin converting enzyme inhibitor zofenopril in a real-world setting. This evidence can provide a snapshot of the potential users of the two molecules in a single pill combination (SPC).
METHODS
Retrospective observational study using data from the IQVIA Italian Longitudinal Patient Database. Adult patients firstly prescribed with amlodipine and zofenopril between 1 July 2011 and 30 June 2020 were identified and demographic and clinical characteristics were extracted. Treatment adherence was evaluated as proportion of days covered (PDC). The potential number of patients eligible for a SPC was calculated.
RESULTS
A population of 2394 hypertensive patients, mean age of 68.6 years ±12.7, 52.6% male were treated with amlodipine and zofenopril. The majority of patients (54.5%) were low adherent (PDC <40%), 25.9% were intermediate adherent and only 19.6% were high adherent (>80%) to therapy. Around 42,500 adult hypertensive patients were estimated to be prescribed the extemporaneous combination in 2019 in Italy, being potentially eligible for treatment with amlodipine and zofenopril SPC.
CONCLUSIONS
The administration of the extemporaneous combination of zofenopril and amlodipine in hypertensive patients is a common practice in Italy. The development of a SPC can be a viable treatment option to simplify therapy and to increase adherence in hypertensive patients who are already on the two monotherapies in combination.
