SOLUBILITY / SOLUTION STABILITY:

Aqueous solutions at 25 mg/mL are faint yellow. No solution stability data are currently available.

 

APPLICATIONS:

1. An oral composition of 20 g apramycin sulfate, 1 g pyridoxal HCl, 10 g sodium alginate,

10 g glycine and about 30 powdered apples were fed to calves and swine in order to treat diarrhea. Pyridoxal HCl was added to enhance the bactericidal activity of apramycin sulfate.3

2. Under the Federal Food, Drug and Cosmetics Act, feed containing 150 g apramycin per ton may be used to control colibacillosis.4

3. Apramycin is a potent inhibitor of protein synthesis in bacteria in vivo and in vitro. To a limited extent, it induces translation errors in cell-free systems from Escherichia coli supplemented with poly(U). Apramycin also inhibits the translocation step of protein synthesis in vivo (e.g., in protoplasts of Bacillus megaterium), and in vitro (e.g., in cell-free systems from E. coli). This may be the drug’s primary inhibitory effect. 5

4. Apramycin sulfate is an aminocyclitol antibiotic whose antibacterial activity has been tested in comparison with neomycin and streptomycin. Of the strains tested, 99% were sensitive to apramycin sulfate, compared to 93% for neomycin and 48% for streptomycin. In vitro resistance development to apramycin sulfate was gradual
