Cefuroxime antacid interactions.
Cefuroxime sodium a second generation semi-synthetic cephalosporin is effective for treating meningitis, lower respiratory tract infections, gonorrhea, bone and joint infections and is approved for surgical prophylaxis. There are number of synergistic and as well as antagonistic drug interactions reported for this antibiotic. Withstanding to gastric irritations caused by this antibiotic, antacids may possibly be co-administered with cefuroxime, which may result in severe adverse drug interaction. The present work describes the effect of magnesium carbonate, magnesium hydroxide, magnesium trisilicate, megaldrate powder, sodium bicarbonate, aluminum oxide and simethicone suspension on the in vitro availability of cefuroxime sodium. The mechanism of interaction between antibiotic and antacids was also studied.
