Pfizer, Boehringer Ingelheim's Spiriva shows promise for treating asthma

According to study results published in the NEJM, the addition of Pfizer's Spiriva (tiotropium) to standard therapy improves symptoms in patients whose asthma is poorly controlled and gives them more days without breathing problems. The data showed that Spiriva worked at least as well as GlaxoSmithKline's Serevent (salmeterol) and better than doubling the steroid dose. Spiriva, which is co-marketed with Boehringer Ingelheim, is already used for chronic obstructive pulmonary disease.
