The findings were published January 26, 2009 on www.pnas.org, the online edition of Proceedings of the National Academy of Sciences of the United States of America, a prestigious scientific journal. The lead investigator, Dr. Richard Bond, and his colleagues demonstrated the absence of asthma-like symptoms in laboratory mice that do not have the very receptor that is inhibited by beta blockers. This finding was in agreement with earlier studies by Bond and his colleagues showing that low doses of beta blockers improved asthma in mice.

Expanding on his description of Dr. Bond's findings, Mr. Smith comments, "Dr. Bond's research has used an approach he calls 'paradoxical pharmacology,' which simply means that patients may be treated with medicines that may initially worsen symptoms, but over the long run may lead to overall health improvement."
