DRUGS & SUPPLEMENTS
Doxycyclin is an semisynthetic tetracycline group's antibiotic of broad-spectrum. This medication has bacteriostatic action due to suppression of protein synthesis of pathogens. It active against aerobic gram-positive bacteria: Staphylococcus spp., Streptococcus spp. (including Streptococcus pneumoniae), Bacillus anthracis, Listeria monocytogenes; anaerobic bacteria: Clostridium spp.
Doxycyclin is also active against aerobic gram-negative bacteria: Neisseria gonorrhoeae, Escherichia coli, Shigella spp., Salmonella spp., Enterobacter spp., Klebsiella spp., Bordetella pertussis, as well as against Rickettsia spp., Treponema spp., Mycoplasma spp. and Chlamydia spp.

After oral administration Doxycyclin is quickly and almost completely absorbed from the gastrointestinal tract. Ingestion has very little effect on the absorption of Doxycyclin. This medication is widely distributed in tissues and body fluids. Plasma protein binding is 80-95%. T1/2 is 12-22 h.
