Details
Cefradine is the first-generation semi-synthetic cephalosporin. It is acid-resistant and can be taken orally. It has good absorption and high blood concentration. It is characterized by resistance to β-lactamase, resistant to drug-resistant Staphylococcus aureus and other broad-spectrum antibiotics. Bacillus has a rapid and reliable bactericidal effect.
Cefradine is clinically mainly used for infections of the respiratory tract, urinary tract, skin and soft tissues, such as bronchitis, pneumonia, pyelonephritis, cystitis, ear, nose, and throat infections, enteritis and dysentery.
