Aspoxicillin is a broad-spectrum antimicrobial agent against 68 isolates of Actinobacillus pleuropneumoniae with an MIC90 value of <= 0.05 μg/ml. Aspoxicillin has a long half-life in mouse serum of 55 minutes[1][2].
Aspoxicillin is a semisynthetic penicillin derivative[2]Aspoxicillin induces postantibiotic effects (PAEs) against Staphylococcus aureus Smith of 1.7 h in vitro[2].
Aspoxicillin induces PAEs against Staphylococcus aureus Smith of 5.2 h in vivo in a thigh infection model in neutropenic mice[2].
