Azithromycin helps prevent COPD set-back episodes

Azithromycin helps prevent COPD set-back episodes

A study outlining the use of weekly azithromycin for COPD patients with frequent exacerbations was published recently in the world’s leading general medical journal, Lancet. “Frequent” was defined as three or more episodes in a year of these episodes of sustained worsening of these patients’ conditions.

Several cogent reasons warrant attempting to prevent these exacerbations. First and foremost, they make the patient sick and can lead to hospitalization, and sometimes to death. Also, each exacerbation can worsen the overall degree of lung impairment, kind of a racheting down in lung function. The patients in the year-long Lancet study were treated with 500 mg. a day of azithromycin for the first three days of each week.

This particular drug was chosen because it has immunomodulatory properties. That is, it works not only as an antimicrobial, but also as an anti-inflammatory. It is concentrated 200 times in the white blood cells, which go to the bronchial tissues. It also has a long half-life of about 70 hours after a dose.

Patients in the trial had 58 percent fewer exacerbations.  Additionally, this benefit lasted for more than six months after the drug was stopped.
