►  Drug Interaction : Drug interaction of Lansoprazole is with Antacids,  Sucralfate , Atazanavir, Voriconazole , Itraconazole , Ketoconazole , Dasatinib, Warfarin , Phenytoin , Diazepam ,
Ref :-   Book : Martindale    Page : 1891,1908,1909   Edition : 37,


  ►    Mechanism of Drug Drug Interaction :  Lansoprazole and other proton pump inhibitors are metabolised by the cytochrome P450 system, primarily by isoenzyme CYP2C19, and to a smaller extent by CYP3A4. Inhibitors or inducers of these isoenzymes may affect exposure to lansoprazole and other proton pump inhibitors. In turn, proton pump inhibitors may alter the metabolism of some drugs metabolised by these enzymes. Lansoprazole may prolong the elimination of diazepam, phenytoin, and warfarin. Lansoprazole and other proton pump inhibitors can reduce the absorption of drugs such as dasatinib, ketoconazole, and itraconazole, whose absorption is dependent on an acid gastric pH. with voriconazole, the plasma concentration of both drugs may be increased. Other proton pump inhibitors may be similarly affected by voriconazole. Lansoprazole and other proton pump inhibitors should not be used with atazanavir, as it substantially reduces exposure to atazanavir. Antacids and sucralfate may reduce the bioavailability of lansoprazole, and should not be taken within 1 hour of a dose of lansoprazole.,

►  Contraindication : hepatic impairment,
Ref :-   Book : Martindale    Page : 1891,1907   Edition : 37,
  ►  Mechanism of Action :   Lansoprazole is a proton pump inhibitor. It suppresses secretion of gastric acid by inhibiting the enzyme system of hydrogen/potassium adenosine triphosphatase (H+/K+ ATPase), the ‘proton pump’ of the gastric parietal cell.,
