Neomycin Sulfate Soluble Powder

Appearance: white powder Pharmacodynamics: Neomycin is an aminoglycoside antibiotic. It acts on the bacteria ribosome, inhibiting the synthesis of protein, strengthening cell membrane permeability, which causes the leakage of some important cell materials such as potassium ion, adenine and nucleotide, leading to the death of the cells. Neomycin is especially effective to the bacteria in rest stage. It has good antibacterial function on staphylococcus aureus and enterobacteriaceae (coli etc.). The bacteria may obtain resistance to neomycin, but the process is slow. There is also partial or complete cross-resistance between neomycin and streptomycin, kanamycin, or gentamicin.Little of neomycin is absorbed if orally or locally applied. When orally applied, only 3% is excreted with urine and most is excreted with dejecta in original shape. A large amount can be absorbed when there is intestinal inflammation or abscess. Functions: This product is used to treat gastrointestinal infections caused by gram-negative bacteria.
