Amoxicillin is a broad-spectrum, pharmacologically active beta-lactam antibiotic effective against Gram-positive and Gram-negative bacteria. Amoxicillin is stable in the gastro-intestinal tract and has higher absorption than naturally occurring penicillins when administrated orally. Amoxicillin is a widely used antibiotic in human and veterinary medicine for the treatment and prevention of respiratory, gastrointestinal, urinary and skin bacterial infections due to its pharmacological and pharmacokinetic properties (Sousa, 2005). Amoxicillin is de-activated by bacterial β-lactamase or penicillinases.


In human medicine amoxicillin is commonly used in combination with clavulanic acid, a penicillinase inhibitor; it is not normally used with clavulanic acid in veterinary use. Amoxicillin is used in many domestic and food animals, including cats, dogs, pigeons, horses, broiler chickens, pigs, goats, sheep, pre-ruminating calves (including veal calves) and cattle. In dogs and cats, amoxicillin is used in respiratory and urinary infections and in soft tissue wounds caused by Gram-positive and Gram-negative pathogenic bacteria (Pfizer, 2004). In poultry, amoxicillin is used for the treatment of susceptible infections of the alimentary, urogenital and respiratory tracts (APVMA, 2007). In pigs, amoxicillin is used to treat major respiratory tract pathogens, mainly caused by Actinobacillus pleuropneumoniae, Streptococcus suis and Pasteurella multocid


In food-producing animals, amoxicillin is approved for use as amoxicillin trihydrate for oral suspensions equivalent to 40 mg amoxicillin twice daily for piglets under 4.5 kg; a soluble powder of amoxicillin trihydrate at 400 mg/45.5 kg body weight (bw) twice daily for pre-ruminating calves, including veal calves, administered by drench or by mixing in milk; amoxicillin trihydrate boluses containing 400 mg of amoxicillin per 45.5 kg bw for pre-ruminating calves, including veal calves; and as a sterile amoxicillin trihydrate powder for use as a suspension at 6.6–11 mg/kg bw once a day, administered by intramuscular (i.m.) or subcutaneous (s.c.) injection in cattle. For sheep, amoxicillin is approved for use as a sterile i.m. injection suspension containing 50 mg/ml at a dose rate of 7 mg/kg bw once a day; as a 150 mg/ml long-acting amoxicillin trihydrate oily i.m. injection suspension at 15 mg/kg bw every two days; and as a 200 mg/ml i.m. injection at 1 ml/20 kg bw for cattle, sheep and pigs (Virbac, 2008, 2011).
