1. Precise Antibacterial Spectrum and Gut Microbiota-Friendly
As a narrow-spectrum antibiotic, it has excellent antibacterial activity against Gram-positive bacteria (especially Clostridium difficile) but little effect on Gram-negative bacteria. Compared with broad-spectrum antibiotics such as vancomycin, it is barely absorbed and mainly exerts its effect in the gastrointestinal tract, without excessively disrupting the balance of normal intestinal flora, thus reducing the risk of subsequent problems caused by flora disturbance.
2. Unique Mechanism of Action and Lower Recurrence Rate
It exerts antibacterial effects by inhibiting the transcription initiation process of bacterial RNA polymerase, with a special target site (binding to the DNA template-RNA polymerase complex to prevent initial DNA strand separation). Different from the mechanism of traditional macrolide antibiotics, it is not prone to cross-resistance. At the same time, it can inhibit the sporulation of Clostridium difficile. Compared with conventional therapeutic drugs, it can better maintain clinical efficacy and reduce the recurrence rate of Clostridium difficile infection.

1. Core Indication: Mainly used for the treatment of Clostridium difficile infection (CDI), including Clostridium difficile-associated diarrhea, and is a specific antibacterial drug for this condition.
2. Other Antibacterial Applications: It has antibacterial activity against Gram-positive bacteria such as staphylococci, most anaerobic Gram-positive bacilli and cocci, and can be used for the treatment of related infections caused by these susceptible bacteria.
3. Research Application Value: Due to its specific inhibition of bacterial transcription process, it can be used as a tool drug in biological research related to bacterial transcription mechanism.
