Efficacy of COPD Medication Decrease on Exposure to Flu Virus and Cigarette Smoke

A new study supports the observations made by health experts that COPD symptom-reliever medication is less effective in flare-ups linked to influenza and cigarette smoking.

The new research points towards a need to develop new drugs for treating COPD patients falling under these categories as well as a new model for testing new drugs.

As per the study, which was done on an animal model of COPD, the efficacy of salbutamol, a common COPD medication for relieving symptoms of the disease, decreases when exposed to influenza A infection and cigarette smoke.

COPD stands for Chronic Obstructive Pulmonary Disease. It is an umbrella term used for describing progressive lung diseases like chronic bronchitis, emphysema, and refractory asthma.

The primary cause of this disease is smoking. The longer you smoke, the more are your chances of developing COPD. Patients have difficulty breathing, because of obstructed airflow, frequent infections of the chest, and regular production of phlegm.

Over a period of time, airways walls become thicker because of greater than normal and continuous mucus production and lasting changes in the lungs occur because of inflammation.

Cigarette smoke makes the symptoms of COPD worse. It also causes flare-ups, besides making a patient more vulnerable to infection.

β2-adrenoceptor agonists, like salbutamol, are commonly used for relieving COPD symptoms. This type of drug work by dilating airways. However, in lung diseases induced by cigarette smoke, like COPD, this type of drug is less effective.
