Partner companies Theravance and the GlaxoSmithKline have received Food and Drug Administration clearance for their new drug for the treatment of COPD, Breo Ellipta. COPD encompasses what used to be known as emphysema and chronic bronchitis – the new drug should be an improvement on current treatment options which can ease the symptoms of this disease. COPD, which is strongly linked to smoking, is the third most significant cause of death in America.
Curtis Rosebraugh, director of FDA Office of Drug Evaluation II, commented that this new long-term maintenance treatment for COPD will provide new care options for the millions of people in the USA who suffer from the condition. The companies have stated that the drug should be available during the third quarter of 2013. Breo Ellipta, which requires a single dose per day, should surpass existing treatments which require two doses.
COPD
COPD stands for chronic obstructive pulmonary disease, a progressive condition (one which continually worsens) which causes breathing problems in those who suffer from it. The symptoms are coughing and the associated overproduction of mucus, shortness of breath especially during exercise and tightness of chest. COPD is also associated with a greater susceptibility to chest-infections. Doctors used to refer to 'emphysema' and 'chronic bronchitis', though these are now officially grouped under this general condition.
A disease which is currently under-diagnosed, this condition refers to the inflammation and subsequent damage to the interior of the lungs, and results in lower efficiency in taking on oxygen and in problems with the mechanics of breathing. Smoking is the top cause of COPD, though a genetic predisposition can cause it in some people. While the damage which it causes cannot be repaired, sufferers who subsequently quit smoking can slow down the progress of the disease.
