Changes in the pattern of antihypertensive medications presented by 100% stacked row graphs compared to the previous year in 2017 vs 2016.

Notes: Other: alpha-blockers or vasodilators. While changes arose in the patterns of antihypertensive medication use during the study period, they were similar from year to year. The treatment change in each patient was tracked and analyzed from year to year. Five categorized groups were identified as follows: (1) Consistent, continued the same therapy; (2) Switch, changed one or both medications to different classes; (3) Add-on, added one or more other drug classes to the existing therapy; (4) Drop-off, dropped at least one class from the existing therapy; and (5) Quit, dropped all classes from the existing therapy, and retained no use of antihypertensive medications the following year. Thus, with monotherapy, drop-off and quit were the same.

Abbreviations: ACEI, angiotensin-converting enzyme inhibitors; ARB, angiotensin II receptor blockers; BB, beta blockers; CCB, calcium channel blockers; DU, diuretics.
