After oral administration, it is completely absorbed from the gastrointestinal tract, and the peak blood concentration is reached 1 to 4 hours after taking the medicine. It is mainly filtered through the glomeruli and secreted into the renal tubules. The urine drug concentration is significantly higher than the blood drug concentration. It can be widely distributed in tissues and body fluids throughout the body, and can penetrate the blood-cerebrospinal fluid barrier and the blood-placental barrier.

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, Spirochete, Amoeba and some Plasmodium are also sensitive to this product. Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia, etc. are sensitive to this product. This product has certain antibacterial activity against gonococci and meningococci, but penicillin-resistant gonococci are also resistant to oxytetracycline. Due to the widespread use of tetracyclines over the years, common clinical pathogens have serious resistance to oxytetracycline, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacteria. There is cross-resistance between different varieties of tetracycline antibiotics.
