Population trends in antihypertensive drug use: results from the MONICA Augsburg Project 1984 to 1995.
Trends in antihypertensive drug use were assessed among 25- to 64-year-old participants of three independent surveys of the MONICA Augsburg region in 1984/85, 1989/90, and in 1994/95. Despite constant prevalences of hypertension, the percentage of hypertensives taking medication increased over the study period. The latter was mainly due to significant rises in antihypertensive monotherapy. By contrast, the use of combination treatments with two or more agents remained constant; however, although combinations composed of only two drugs were taken more often in 1995, those with three or more agents and fixed-dose preparations decreased substantially. Beta-blockers were most frequently, and with a rising tendency, taken as antihypertensive monotherapy. Newer drug classes like calcium channel blockers and ACE-inhibitors were introduced as monotherapy more hesitantly. Diuretics persisted as the basis of antihypertensive combination therapy. The use of combination therapies containing obsolete drugs, like reserpine, declined significantly with corresponding increases in drug combinations of, in particular, calcium channel blockers or ACE-inhibitors. We conclude that monotherapies account for most of the rising antihypertensive treatment rates and probably reflect intensified therapy of borderline hypertensives. The trends in antihypertensive drug classes and treatment regimens reflect a less rapid adoption of novel therapeutic concepts but a fairly close adherence to national and international guidelines.
