Azithromycin dispersible tablets are commonly used clinically as anti-infective drugs, which exert antibacterial effects by inhibiting bacterial protein synthesis. It is commonly used clinically for the following infections caused by sensitive bacteria: respiratory infections (pharyngitis, sinusitis, tonsillitis, community-acquired pneumonia, hospital-acquired pneumonia, acute attacks of chronic bronchitis, etc.); cervicitis, urethritis, pelvic inflammatory disease caused by Chlamydia trachomatis and non-multi-drug resistant Neisseria gonorrhoeae; skin and soft tissue infections (e.g. cellulitis, abscesses, sepsis, etc.). Dosage: For the treatment of STDs caused by Chlamydia trachomatis or gonococcus in adults, a single oral dose of 1g is sufficient. For the treatment of other infections, 0.5g is taken in a single dose once daily for three days; or 0.5g on the first day and 0.25g once daily from the second to the fifth day. The total dose is 1.5g for both the three-day regimen and the five-day regimen. Azithromycin dispersible tablets have a low incidence of adverse reactions, mainly gastrointestinal reactions, which may manifest as nausea, stomach upset, vomiting, diarrhea and abdominal pain, and are generally tolerated. Elevated hepatic transaminases are occasionally seen. Azithromycin should be used with caution in patients with liver disease because it is mainly excreted through the hepatobiliary system. As an anti-infective drug, blood test and bacterial culture should be performed before using this drug to determine bacterial infection before applying antibacterial drugs. The specific application should be combined with the clinical situation and guided by the doctor’s interview.
