Use of individual antihypertensive drug classes and combination therapies during the COVID-19 pandemic in Poland: a cross-sectional, nationwide study in the years 2019-2021.

Introduction: The 2018 European Society of Cardiology / European Society of Hypertension guidelines recommended the use of combination therapy, especially in the form of single‑pill combinations (SPCs), for treatment of hypertension.

Objectives: We assessed adherence to these recommendations after their publication and during the COVID‑19 pandemic in Poland.

Patients And Methods: The frequencies of using individual antihypertensive drug classes and their combinations were analyzed for the years 2019, 2020, and 2021 in all patients who filled at least 1 prescription for an antihypertensive drug, using information from a database covering all prescriptions filled in Poland.
