Management of COPD exacerbations: pharmacotherapeutics of medications.

Chronic obstructive pulmonary disease (COPD) is widely established as a health challenge, with predictions that it will be the third leading cause of global mortality and reduced health status within the next 10 years. Exacerbations of COPD are now the second largest cause of emergency hospitalisation in the UK. The respiratory clinical nurse specialist has an active role in the acute management of COPD exacerbations in the hospital setting, and it is essential that prescribing decisions are made based on the best available evidence. This article critically evaluates the pharmacotherapeutics and evidence base for the use of two medications, salbutamol and amoxicillin, in treating unstable COPD, and discusses implications for clinical practice.
