BACKGROUND: The goal of this retrospective cohort study was to investigate 3-year persistence with antihypertensive drug therapy and the association between antihypertensive drug classes and therapy discontinuation risk in Germany.
MATERIALS AND METHODS: The present retrospective cohort study was based on the IQVIA longitudinal prescription database (LRx) and included adult outpatients (≥ 18 years) with an initial prescription of antihypertensive monotherapy alone including diuretics (DIU), β-blockers (BB), calcium channel blockers (CCB), ACE inhibitors (ACEi), and angiotensin II receptor blockers (ARB) in Germany between January 2017 and December 2019 (index date). A Cox proportional hazards regression model was also used to assess the relationship between antihypertensive drug classes and non-persistence adjusted for age and sex.
RESULTS: This study included 2,801,469 patients. Patients on ARB monotherapy exhibited the highest persistence within 1 year (39.4%) and 3 years (21.7%) after the index date. Patients on DIU monotherapy showed the lowest persistence (16.5% after 1 year, 6.2% 3 years after the index date). In the overall population, initial monotherapy with DIU (HR: 1.48) was positively associated with monotherapy discontinuation, whereas ARB monotherapy was (HR = 0.74) negatively associated with monotherapy discontinuation compared to BB. However, in the age group > 80, there was a slight negative association between DIU intake and monotherapy discontinuation (HR = 0.91).
CONCLUSION: This large cohort study reveals significant differences in 3-year persistence with antihypertensives, which were strongest for ARB and weakest for DIU. However, the differences also depended on age, with much better DIU persistence in the elderly.
