A long acting broad spectrum amoxicillin based antibiotic for use in cattle, pigs, sheep, dogs and cats where a single injection giving prolonged antibiotic cover is required. It may also protect from secondary bacterial invasion in cases where bacteria are not the initial cause of the disease.

Indications include infections of: Alimentary tract, Respiratory tract, Skin and soft tissue, Urogenital tract and in prevention of post-operative infection (treat before surgery). In vitro amoxicillin is effective against a wide range of Gram-positive and Gram-negative bacteria which include: Escherichia coli, Klebsiella pneumonia, Proteus spp., Salmonella spp. staphylococci and streptococci.


Amoxycillin long-acting is a broad-spectrum, semi-synthetic penicillin, active against both Gram-positive and Gram-negative bacteria. The range of effect includes Streptococci, not penicillinase-producing Staphylococci, Bacillus anthracis, Corynebacterium spp., Clostridium spp., Brucella spp., Haemophilus spp., Pasteurella spp., Salmonella spp., Moraxella spp., E. coli, Erysipelothrix rhusiopathiae, Fusiformis, Bordetella spp., Diplococci, Micrococci and Sphaerophorus necrophorus. Amoxycillin has many advantages; it is non-toxic, has good intestinal resorption, is stable in acidic conditions and is bactericidal. The drug is destroyed by e.g. penicillinase-producing staphylococci and some Gram-negative strains.

Amoxicillin is semisynthetic broad-spectrum penicillin with a bactericidal effect against gram-positive and gram-negative bacteria. It is used in the treatments of gastrointestinal, respiratory and urinary tract infections caused by amoxicillin sensitive micro-organisms, like Campylobacter, Clostridium, Corynebacterium, E. coli, Erysipelothrix, Haemophilus, Pasteurella, Salmonella, penicillinase negative Staphylococcus and Streptococcus spp. in calves, cattle, goats, sheep, and swine. The antibiotic is bound to a special binding protein, the synthesis of the cell wall is inhibited by the blockage of synthesis of peptidoglycan, and autolytic enzymes are activated in the cell wall resulting in wall lesions and cell death. Amoxicillin is mainly excreted in urine. A major part can also be excreted in bile.


For intramuscular injection. Shake well before use.

  • General dose : 1 ml per 15 kg bodyweight.

This dosage may be repeated after 48 hours if necessary.
