Ceftibuten is a 3rd generation cephalosporin that is FDA approved for the treatment of acute bacterial exacerbations of chronic bronchitis, acute bacterial otitis media, pharyngitis and tonsillitis. Ceftibuten exerts its bactericidal action by binding to essential target proteins of the bacterial cell wall. This binding leads to inhibition of cell-wall synthesis. Common adverse reactions include diarrhea, nausea, vomiting and headache. The effect of increased gastric pH on the bioavailability of ceftibuten was evaluated in 18 healthy adult volunteers. Each volunteer was administered one 400-mg ceftibuten capsule. A single dose of liquid antacid did not affect the Cmax or AUC of ceftibuten; however, 150 mg of ranitidine q12h for 3 days increased the ceftibuten Cmax by 23% and ceftibuten AUC by 16%.
