Description
Oxytetracycline is a pale yellow crystalline or amorphous powder, odorless, darker in daylight. It is very slightly soluble in water. It dissolves in dilute acid and alkaline solutions.
Application
Oxytetracycline is a broad-spectrum antibiotic that inhibits both Gram-positive and Gram-negative bacteria and also acts as a growth promoting agent. The antibacterial spectrum and antibacterial principle of oxytetracycline are basically the same as those of tetracycline. The curative effect on intestinal infection (including amoebic dysentery) is slightly better than that of chlortetracycline and tetracycline. Other indications are the same as tetracycline.
