Interesting approach. Undermines the standard approach of pharmacy companies to view each drug as a separate profit center....
Approximately one in three Americans has high blood pressure, but only about half of those who do have the condition under control. One common reason: they stop taking their medications, often because of troublesome side effects such as weakness, fatigue, or a dry cough. However, taking smaller doses of several different blood pressure drugs may be a good way to address these issues, a new analysis suggests.
Researchers found that taking a quarter-dose of a two-drug combination was just as effective at lowering blood pressure as taking a full dose of one drug. Taking a quarter-dose of a four-drug combination was even more effective (although it's important to note that this finding came from a single, small trial). People who took smaller doses of multiple drugs had fewer side effects than those taking a single drug at the full dose. In fact, their side effects were similar to those of people who took placebos. The study was published in the July 2017 issue of Hypertension.
