VEETIDS '500'

Penicillin Antibiotic

Category C

Head-to-Head

Clinical Matrix

Mechanism of Action

Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.

VEETIDS '500' (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis. It has activity against both gram-positive and gram-negative bacteria.

Clinical Dosing

3.375 g IV every 6 hours (piperacillin-tazobactam); for piperacillin alone, 3 g IV every 6 hours.

1 tablet (500 mg) orally twice daily for 7 days.

Direct Interaction

None Documented

Half-Life

0.6-1.2 hours in adults with normal renal function; prolonged to 2-6 hours in renal impairment (CrCl <20 mL/min); requires dose adjustment in renal failure

Other Significant Interactions

Clinical Note

moderate

Piperacillin + Probenecid

"The serum concentration of Probenecid can be increased when it is combined with Piperacillin."

Clinical Note

moderate

Piperacillin + Mycophenolic acid

"The serum concentration of the active metabolites of Mycophenolic acid can be reduced when Mycophenolic acid is used in combination with Piperacillin resulting in a loss in efficacy."

Clinical Note

moderate

Piperacillin + Plicamycin

"The serum concentration of Plicamycin can be decreased when it is combined with Piperacillin."
