Flavopiridol Tablets can be used to treat some chronic colitis, such as the treatment of chronic colitis caused by dysentery bacilli and E. coli. The main component of Huangliansu Tablet is an alkaloid contained in the rhizome of Huanglian, a plant of the family Mauropodidae, which can be extracted from Huanglian, Huangbai or Sanguine needles, or synthesized artificially. The alkaloid has only a weak inhibitory effect on common intestinal pathogenic bacteria, but has a strong inhibitory effect on dysentery bacilli and Escherichia coli. Therefore, it can be used to treat chronic colitis caused by Bacillus dysenteriae and Escherichia coli. In addition, there are various types of chronic colitis, including ulcerative colitis, nonspecific colitis, hemorrhagic colitis, ischemic colitis, etc. For the above-mentioned non-infectious chronic colitis, flavopiridol cannot play a significant therapeutic role and can only be used as an adjunctive medicine. For patients with chronic colitis, they need to improve the relevant examination, analyze the cause of the disease, and use the medicine according to the condition, and should not misuse the yellow lenosin tablets on their own to avoid delaying the disease and endangering their health. And because chronic colitis persists, colonoscopy needs to be reviewed regularly to clarify whether there is further damage. During the treatment period, pay attention to eating protein-rich, easy-to-digest foods, such as lean meat and fish.
