Biological Activity

Description	Amoxicillin (Amoxycillin) is a moderate-spectrum, bacteriolytic, β-lactam antibiotic used to treat bacterial infections caused by susceptible microorganisms.
In vitro	Amoxicillin treated cells secrete high amounts of interleukin-5 and mostly lower or no amounts of tumor necrosis factor alpha, interleukin-4, and interferon-gamma. Amoxicillin-specific T cell clones fails to show drug-specific cytotoxicity, but killed target cells in the presence of concanavalin A, indicating a principal ability to be cytolytic. ^[1] Amoxicillin releases faster in pH 1.0 hydrochloric acid (HCl) than in pH 7.8 phosphate buffer. Amoxicillin would be degraded to some extent in a pH 1.0 HCl medium at 37 degrees C, which indicated that amoxicillin is not stable in an acidic surrounding. ^[2] Amoxicillin inhibits 4 of 15 isolates at 8 mg/mL or less but is not bactericidal against any of the isolates at that concentration. Amoxicillin in combination with clavulanic acid is bactericidal for 14 of 15 isolates tested at an amoxicillin concentration of 4 mg/mL or less and a clavulanic acid concentration of 2 mg/mL or less. ^[3] Amoxicillin inhibits 50% of isolates tested decreased from 0.5 mg/mL (range, 0.25 to 1 mg/mL) to 0.06 mg/mL (range, 0.01 to 0.25 mg/mL) in the presence of only 4 mg of cefotaxime per mL. ^[4]
