Inhaler leaves users breathless
U.S. and British researchers have released the results of a study which indicate that the use of a particular mist inhaler produced by Pfizer could increase the risk of dying by its users by 52 percent.
The inhaler is used by people with lung diseases including chronic bronchitis and emphysema.
“What we think is going on is that the mist inhaler is delivering a higher concentration of tiotropium than it should be and that may be increasing the risk of death,” said, the leader of the study, Dr. Sonal Singh of Johns Hopkins University School of Medicine.
The results of the study were contested by Pfizer. This is very surprising because drug companies are usually very proactive about taking on responsibility, or taking drugs off the market that may pose a risk to users. Perhaps Pfizer concluded that dying of an overdose of tiotropium is more desirable than asphyxiation due to an obstructive pulmonary disease.
