Daily Placebo Works Better Than Taking An Active Drug Irregularly

Posted: Tuesday, November 30, 2004

Regular pill popping decreases heart risks.

When it comes to heart disease, it may not be what pill you take, but how regularly you take it that is important. The finding controversially implies that so long as patients stick to a daily regime, they would do just as well with a placebo.

Bradi Granger of Duke University in Durham, North Carolina, and her colleagues re-analyzed the results of a clinical trial involving nearly 7,600 heart-failure patients who were testing an experimental angiotensin receptor blocker (ARB), which relaxes blood vessels and lowers blood pressure.

Experts suspect that those who stick to their medicine are also more likely to stick to other heart-healthy activities such as regular exercise, good diet and not smoking or drinking. These behaviours alone probably outweigh the physiological effect of the drug.

If doctors could identify those patients who are unlikely to take their drugs regularly, Granger believes that they could be targeted with education or social support that would encourage them to follow a healthier lifestyle.

Two other earlier investigations have also shown that patients with heart disease get benefits from taking a regular placebo that almost match those provided by beta-blockers or lipid-lowering drugs. But researchers have struggled to explain exactly what is different about those who follow their doctor's instructions compared with those who flout them.

Another, more controversial, implication of the new results is that those people who are diligent about taking their drugs and following a healthy lifestyle might reap the same benefit if they cut their dose or switched from active drugs to a cheaper placebo. "It's definitely worth a study," Granger says.
