Reversible lansoprazole-induced interstitial lung disease showing improvement after drug cessation.

Lansoprazole is an acid proton-pump inhibiting drug that is used for the treatment of duodenal or gastric ulcers, H. pylori infection, gastroesophageal reflux disease or Zollinger-Ellison syndrome. Although lansoprazole is well known for its gastrointestinal and dermatologic adverse effects, mild pulmonary symptoms are also known to develop from taking this drug. There have been no reports about lansoprazole-induced interstitial lung disease. We report here a case of lansoprazole-induced interstitial lung disease that developed in a 66-year-old man.

Proton pump inhibitor treatment of patients with gastroesophageal reflux-related chronic cough： A comparison between two different daily doses of lansoprazole

AIM:To compare two different daily doses oflansoprazole given for 12 weeks and to assess the roleof gastrointestinal (GI) investigations as criteria forselecting patients.METHODS:Out of 45 patients referred for unexplainedchronic persistent cough,36 had at least one of theGI investigations (endoscopy,24-h esophageal pH-metry and a 4-week trial of proton pump inhibitor (PPI)therapy) positive and were randomly assigned to receiveeither 30 mg lansoprazole o.d.or 30 mg lansoprazoleb.i.d,for 12 weeks.Symptoms were evaluated atbaseline (visit 1) after the PPI test (visit 2) and after the12-week lansoprazole treatment period (visit 3).RESULTS:Thirty-five patients completed the studyprotocol.Twenty-one patients (60.0%) reportedcomplete relief from their cough with no differencebetween the two treatment groups (58.8% and 61.1%had no cough in 30 mg lansoprazole and 60 mglansoprazole groups,respectively).More than 80% ofthe patients who had complete relief from their cough atthe end of the treatment showed a positive response tothe PPI test.CONCLUSION:Twelve weeks of lansoprazole treatmenteven at a standard daily dose,is effective in patientswith chronic persistent cough.A positive response to aninitial PPI test seems to be the best criterion for selectingpatients who respond to therapy.     

Long-Term Efficacy of Lansoprazole in Preventing Relapse of Erosive Reflux Esophagitis

In a phase III study of lansoprazole treatment, patients with healed or unhealed erosive esophagitis entered a titrated open-label treatment period and received lansoprazole for ≤6 years to assess long-term maintenance therapy. Doses were adjusted depending on symptom response. Endoscopy was performed yearly. One hundred ninety-five subjects received lansoprazole for <1 to 72 months; most received daily doses of ≤30 mg. Lansoprazole maintained erosive esophagitis remission in 75% of subjects receiving treatment for ≤72 months, with 39 subjects experiencing 50 recurrences. Most subjects (94–95%) had no or mild symptoms of day or night heartburn at study end, and 77% were asymptomatic at first erosive esophagitis recurrence. The most common treatment-related adverse events included diarrhea (10%), headache (8%), and abdominal pain (6%), and were mild or moderate in severity. Long-term lansoprazole is effective and well tolerated when used to maintain erosive esophagitis remission for ≤6 years.
