"Not only do minorities get asthma at a higher rate, but [UCSF] pulmonologist Dr. Esteban Burchard ... has found that ethnicity is the most important factor in determining if a patient will respond to asthma therapy. Unfortunately, for the most most commonly prescribed asthma medication, Albuterol, 67 percent of Puerto Ricans and 47 percent of African-Americans show no improvement when taking it, yet Albuterol works therapeutically for the vast majority of Caucasian patients."
I did not know that. It's horrifying.
