Sodium Bicarbonate - Vantin (Cefpodoxime Proxetil) Interaction

Interaction Details

Cefpodoxime Proxetil is classified as belonging to the following category: Cefpodoxime Proxetil (Vantin)

Theoretically, sodium bicarbonate might reduce the levels and clinical effects of cefpodoxime.
Cefpodoxime proxetil is an oral prodrug that is de-esterified in the intestine to the active drug cefpodoxime. Drugs or supplements that increase gastric pH can inhibit the activation of cefpodoxime proxetil and reduce the peak plasma concentrations of cefpodoxime. In humans, taking sodium bicarbonate 12.6 grams orally along with cefpodoxime proxetil 200 mg reduces peak plasma concentrations and area under the plasma concentration-time curve (AUC) of cefpodoxime by 35% to 50%.

Likelihood of Occurrence

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.

Cefpodoxime Proxetil Overview

• Cefpodoxime is used to treat certain infections caused by bacteria such as bronchitis (infection of the airway tubes leading to the lungs); pneumonia; gonorrhea (a sexually transmitted disease); and infections of the skin, ear, sinuses, throat, tonsils, and urinary tract. Cefpodoxime is in a class of medications called cephalosporin antibiotics. It works by stopping the growth of bacteria.

• Antibiotics such as cefpodoxime will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
