Ampicillin (sodium salt)

Ampicillin is a broad-spectrum antibiotic with activity against Gram-positive and Gram-negative bacteria, including veterinary isolates of S. pseudintermedius, S. aureus, E. coli, Pasteurella, and S. canis (MIC50s = 0.25, 0.5, 2, 0.12, and 0.25 µg/ml, respectively). In vivo, ampicillin (80 mg/kg, i.v.) reduces cough frequency, tachypnea, dyspnea, and fever and increases survival in a baboon (P. cynocephalus) model of pneumococcal pneumonia. Formulations containing ampicillin have been used to treat a variety of bacterial infections.Formal Name: (2S,5R,6R)-6-[[(2R)-2-amino-2-phenylacetyl]amino]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid, monosodium salt.
