Amoxicillin is not an antiviral drug, it is an antimicrobial agent, which is a broad-spectrum penicillin antibiotic for respiratory tract infections, urinary tract infections, gastrointestinal tract infections, skin and soft tissue infections caused by sensitive bacteria. Amoxicillin has a similar mechanism of action to penicillin, leading to bacterial death by inhibiting bacterial cell wall biosynthesis, and has a bactericidal effect on sensitive bacteria in the proliferative phase. Amoxicillin has powerful bacteriostatic and bactericidal effects on most pathogenic gram-positive and negative bacteria. It is generally used for the treatment of the following diseases caused by sensitive bacteria, such as hemolytic streptococcus, streptococcus pneumoniae, staphylococcus, and Haemophilus influenzae caused by otitis media, sinusitis, pharyngitis, tonsillitis and so on.
