Doxycycline Hyclate is a semi synthetic tetracycline antibiotic, which can penetrate the cell membrane and bind to the 30S ribosome subunit, interfere with the tRNA/mRNA interaction, and ultimately inhibit protein synthesis. As a broad-spectrum antibiotic and antibacterial agent, has strong resistance to bacteria that cause respiratory infections, including Mycoplasma pneumoniae and Haemophilus influenzae. In addition, it can also treat infections caused by Chlamydia, Rickettsia, and certain spirochetes, and has antigenic and insecticidal properties.
