Current drug treatment, chronic and acute.

The appropriate management of chronic obstructive pulmonary disease (COPD) involves more than taking prescription medicines. The key components have been set out in detail in many treatment guidelines, both national and international. They include the avoidance of identified risk factors, especially tobacco smoking, and the optimization of daily physical activity. This article reviews the key components of the pharmacologic treatment of COPD, both acute and chronic, with an emphasis on those recent studies, which are likely to change practice in the next few years.
