This treatment applies to the following species:
VETERINARY USE ONLY
An antibiotic for oral use in pigs.
Active Ingredient: Each jar contains Apramycin Base (as apramycin sulfate) 50 g
Apralan Soluble powder is a water soluble preparation containing apramycin sulfate. Apramycin is a broad spectrum antibiotic of the aminocyclitol group, produced by the actinomycete Streptomyces tenebrarius. This compound is highly soluble in water, slightly soluble in the lower alcohols and essentially insoluble otherwise.
In Vitro Activity
In vitro tests demonstrate that apramycin is effective against certain gram-positive and gram-negative bacteria.
Minimum Inhibitory Concentration1 (µg/mL)
Group D Streptococcus
Group E Streptococcus
1Data generated by standard broth dilution microtiter test.
Commonly encountered gram-negative enteric bacteria have been extensively studied for sensitivity to apramycin. Of a total of 758 Escherichia coli and Salmonella sp. isolated from animals in the United States, Europe, Taiwan and the Philippines, 738 (97.4%) were susceptible to 16 µg/mL or less of the antibiotic.
Antibacterial Effect And Mode Of Action
Apramycin, as other aminoglycoside-aminocyclitol antibiotics, acts against bacteria by exerting marked inhibitory effects on protein synthesis at the ribosome level. Apramycin has been shown to be a potent inhibitor of protein synthesis in bacteria1. Apramycin inhibits the translocation step of protein synthesis and induces translation errors. At low concentrations, apramycin inhibits protein synthesis more effectively than kanamycin A, streptomycin, amikacin or gentamicin.
Apramycin is excreted by the kidney as the intact molecule. Apramycin is absorbed when administered orally to neonatal swine at single dosage levels of 10, 30 and 100 mg/kg with peak blood levels observed at one to four hours. Detectable serum levels persist for 12 to 24 hours. Considerable variation in post-administration blood levels is observed; however, the level detected is generally commensurate with the dose. Oral absorption of apramycin decreases markedly as pigs increase in age.

Safety And Toxicity
Apramycin is an extremely safe compound. In acute toxicity studies in various species, no mortality was observed when apramycin was administered as a single gavage dose ranging from 520 mg/kg body weight (dog, chicken), to 5200 mg/kg (mice). Chronic toxicity studies have generated no effect levels of 50 ppm in dogs fed for one year, and 200 and 10000 ppm no effect levels when fed to mice and rats respectively for two years. No adverse effects on mutagenicity, teratology or reproduction have been observed in laboratory animals.
In swine, apramycin levels given as acute oral doses yielded no mortality at the highest tested level of 1250 mg/kg body weight. No adverse effects on reproductive performance have been observed.
Two studies were conducted to determine the effect of oral doses of apramycin sulfate upon the fecal consistency of baby pigs. In the first study, baby pigs were dosed with 50, 100 and 200 mg apramycin activity/pig in 2 mL of water on days one, two and three following birth. In the second study, baby pigs were dosed with 200 mg apramycin activity in 2 mL of water for three days starting on day one, three or five following birth. All treatments resulted in a decreased firmness of the feces except the single daily dose of 50 mg apramycin activity. All treated pigs gained more from birth to two weeks and had a higher percent survival than the controls.
Pigs: For the treatment of bacterial enteritis caused by susceptible strains of Escherichia coli.
For treatment of colibacillosis, pigs should consume sufficient medicated drinking water to obtain 12.5 mg of apramycin activity per kg of body weight daily. Continue treatment for seven days. Prepare fresh medicated solution daily to assure activity.
Directions For Use
Add Apralan Soluble Powder to the only source of drinking water to provide the desired apramycin activity of 100 mg/litre. See following table.
Apralan Soluble Powder/Day
Apramycin Activity (g)
Approx. Total Body wt. to be treated (kg)
Approx. Daily Water Consumption (litres)
1 g measure
5 g measure
Add the appropriate quantity of Apralan Soluble Powder to five to ten times its own volume of water. Stir well and allow solution to stand for a few minutes, then stir again. When completely dissolved, add to the full volume of drinking water and stir well. Prepare fresh medicated drinking water every 24 hours to assure activity.
Drinking water and delivery system must be free of rust to avoid reduction of activity.
Treated animals must not be slaughtered for use in food for at least 28 days after the latest treatment with this drug.
