Ampicillin is a synthetic penicillin antimicrobial drug similar in activity to amoxicillin, bactericidal against Gram-positive and some Gram-negative bacteria[1].

In canine medicine, this drug is used to treat cystitis, otitis media and bacterial meningitis.

Resistance is commonly reported with Salmonella spp and Escherichia coli[2].

The use of this drug should be reserved for documented cases where culture and sensitivity have confirmed its suitability[3].

Recommended dose rate in dogs is 20 - 60 mg/kg given orally every 8 - 12 hrs.
