- Treatment duration is for at least 6 months
- Other macrolides (Clarithromycin, Roxithromycin, Azithromycin) are used when Erythromycin is ineffective or not tolerated
- Studies show better lung function (decreased dyspnea, opacities in HRCT) w/ Azithromycin use in patients w/ DPB
Actions:
- Inhibit production of pro-inflammatory cytokines & formation of leukotriene B4
