Abstract
Objective: The need for polytherapy is common among people affected by arterial hypertension (AH). A single-pill combination is a response to decreased medication adherence, especially in elderly people often suffering from more than one disease, which tends to improve blood pressure control and cardiovascular outcomes. The aim of our study was to determine the frequency of use of a single-pill antihypertensive combination (SPC) therapy and possible differences in presence of comorbidities. Design and method: 324 hypertensive participants on pharmacological treatment were included in this research, of which 51.2% were men, and with an overall median age of 64 years (IQR = 17). For each participant undergoing 24-hour ambulatory blood pressure measurement, data about pharmacological therapy, weight, height and comorbidities such as chronic kidney disease (CKD) and diabetes mellitus (DM) were obtained from their most recent medical records combined with self reports. Body mass index (BMI) was calculated. Results: 148 (45.7%) participants were prescribed a SPC. Participants taking a SPC had lower presence of CKD (23.7% with CKD vs. 76.3% without CKD, p<0.001). No significant difference was found in the presence of DM (p = 0.496). Another interesting finding was more frequent use of SPC therapy among patients with higher BMI (p = 0.029). Conclusions: The results show that less than half of the participants in our study were prescribed an SPC. From this we can conclude that more attention should be paid to educating people about the options for antihypertensive treatment and simplifying therapy regimen. Another point we should highlight is the limited availability of SPCs in the treatment of hypertension in patients suffering from CKD.
