Cefdinir and cephalexin are cephalosporin antibiotics commonly used in the treatment of urinary tract infections (UTIs). Their efficacy depends on achieving sufficient time with concentrations exceeding the minimum inhibitory concentration (MIC). Despite being frequently prescribed for UTIs, cefdinir has markedly lower urine penetration compared to cephalexin. It is possible that differences in pharmacokinetics could result in dissimilar efficacy between these agents; however, comparative studies of cephalosporins in UTIs are lacking.
