一般說明

Erythromycin is an antibiotic produced by growth of certain strains of Streptomyces erythreus. Erythromycin, a bacteriostatic antibiotic, inhibits the growth of bacteria instead of killing them directly. It functions as a cytochrome P-450 inhibitor and is primarily excreted through bile. Erythromycin consists primarily of erythromycin A (C37H67NO13). The sum of the percentages of erythromycin A, erythromycin B, and erythromycin C is NLT 85.0% and NMT 100.5%, calculated on the anhydrous basis. Erythromycin demonstrates activity against both gram-positive and gram-negative bacteria, as well as other organisms. Erythromycin has been used as a motilin receptor agonist, to block respiratory glycoconjugate secretion in human airways in vitro, and for selecting plasmid-cured and recombinant lactococcus lactis MG1363 strains.
