Cephradine  (Synonyms: Cefradine; SQ-11436)

Cephradine (Cefradine) is a broad-spectrum and orally active cephalosporin. Cephradine is active against both gram-positive and gram-negative pathogens. Cephradine is effective in eradicating most penicillinase-producing organisms. Cephradine has been used in the research of genitourinary, gastrointestinal and respiratory tract infections, and in infections of the skin and soft tissues. Cephradine blocks solar-ultraviolet induced skin inflammation through direct inhibition of TOPK^[1][2][3].

Cephradine (0~8 μg/mL; 12 hours) makes bacterial viability rapidly increased at antibiotic concentrations below the MIC (minimum inhibitory concentration) of 0.70 μg/mL at both pH 7.4 and pH 5.5^[4].

Cephradine (25 mg/kg; s.c.; 11 days) reduces the bacterial density and counts in the abscesses^[4].
