Product Information
Main Ingredients: Chlortetracycline
Description: This product is a brown or brownish-yellow powder or granule, free from caking, mold, and odor.
Pharmacological Actions: Chlortetracycline belongs to the tetracycline class of broad-spectrum antibiotics. It has a relatively strong effect on Gram-positive bacteria such as Staphylococcus, Streptococcus hemolyticus, Bacillus anthracis, Clostridium tetani, and Clostridium perfringens, but is less effective than β-lactams. It is relatively sensitive to Gram-negative bacteria such as Escherichia coli, Salmonella, Brucella, and Pasteurella, but less effective than aminoglycosides and amide alcohols (phenicols). This product also has inhibitory effects on Rickettsia, Chlamydia, Mycoplasma, Spirochetes, Actinomyces, and certain protozoa.
Drug Interactions: Chlortetracycline can form insoluble complexes with polyvalent metal ions such as magnesium, calcium, aluminum, iron, zinc, and manganese, thereby affecting drug absorption. Therefore, it should not be co-administered with drugs, feeds, or dairy products containing the aforementioned polyvalent metal ions.
