Placebos ‘Improve’ Asthma Symptoms

A fake treatment (placebo) can make asthma patients feel better just as well as a real treatment, a new study suggests. But tests showed the real treatment improved breathing more. The study included 39 asthma patients. Each person visited a doctor’s office 3 times, with a few days between visits. They received treatments each time, in random order. They were treated with a standard albuterol inhaler, a fake inhaler or fake acupuncture. They also were given no treatment sometimes. People also received repeated tests of their ability to exhale. These tests showed 20% improvement with the albuterol inhaler and 7% with the other approaches. But patients thought their breathing improved about 45% to 50% with all three of the active treatments. They thought there was a 21% improvement with no treatment. The study raises many questions about the so-called placebo effect.
