Characterization of Placebo Responses in Stable Asthma

Completed · Not applicable · Has a placebo group

Conditions studied: Asthma Placebo Effects

In brief

The investigators hypothesize that different placebos will have different effects on subjective and objective asthma outcomes compared with actual therapy and natural history. . Subjects with asthma are randomly treated with placebo inhaler, placebo acupuncture, albuterol inhaler, or "no treatment" in random order, on three different occasions each. At each of the 12 visits, spirometry is performed repeatedly over 2 hours. Maximum FEV1 achieved and an 11-point, self-reported scale of improvement are examined.
