Effects of ACE inhibitors and angiotensin receptor blockers: protocol for a UK cohort study using routinely collected electronic health records with validation against the ONTARGET trial

Great Sustainability Results From Appropriate Antihypertensive Therapy

Cardiovascular diseases are emerging as a major cause of death and hospitalization in the Western world. For many years, a number of medicines have been placed on the market, in well-established and safe use for antihypertensive therapy. The various classes of antihypertensives in established use include, ACE inhibitors, as monotherapy or in combination with diuretics or calcium antagonists, sartans, calcium antagonists, beta blockers, and diuretics. Among these medicines classes there are differences in mechanism of action, efficacy in reducing blood pression, tolerability, and cost. In fact, there are wide differences in the monthly cost of therapy within each class and among the classes themselves. In this analysis we describe an example about the prescribing trends of antihypertensive drugs at a European sample represented by an Italian health care company of about 1 million inhabitants. Aspects of pharmacoeconomics, pharmacoutilization, and pharmacological differences are described.
