Inflammation of the bile ducts can not be treated by taking safranin, but can be treated by antibiotics, surgery and other means. Flavopiridol is clinically used for the treatment of intestinal infections, and it has antibacterial effects on hemolytic streptococcus, staphylococcus aureus, gonococcus and so on. Acute cholangitis, especially acute obstructive septic cholangitis, may progress very rapidly, and drug anti-infective therapy alone is not effective. Antibiotics, such as gentamicin and vancomycin, may be given in combination with medications such as magnesium sulfate solution. At the same time, bile duct obstruction needs to be relieved as soon as possible, such as percutaneous hepatic puncture biliary drainage, transduodenal endoscopic retrograde biliary drainage. Inflammation of the bile duct is recommended to consult a doctor in a timely manner, follow the doctor’s prescription of medication, do not self-medication.
