Pharmacology

Mechanism of Action

Inhibits protein synthesis in susceptible organisms by binding to 50S ribosomal subunits, thereby inhibiting translocation of aminoacyl transfer-RNA and inhibiting polypeptide synthesis

Exerts effect only against multiplying organisms; penetrates cell wall of gram-positive bacteria more readily than that of gram-negative bacteria, and thus, gram-positive organisms may accumulate 100 times more erythromycin than gram-negative organisms do

Absorption

Unknown whether erythromycin is absorbed from mucous membranes to any substantial extent
