erythromycin/eryth·ro·my·cin/ (-mi´sin) a broad-spectrum antibiotic produced by Streptomyces erythreus; used against gram-positive bacteria and certain gram-negative bacteria, spirochetes, some rickettsiae, Entamoeba, and Mycoplasma pneumoniae; used in the form of the gluceptate, lactobionate, stearate, and other salts.

erythromycinAn antibiotic of the macrolide class with an action similar to that of the tetracyclines. It binds to the RIBOSOMES in bacterial cells and interferes with the synthesis of protein. Oral erythromycin extends cardiac repolarization. It is metabolized by cytochrome P-450 3A isoenzymes and drugs such as nitroimidazole antifungals, verapamil, diltiazen and troleandomycin that inhibit CTP3A can increase the risk of ventricular arrhythmias and sudden death. Erythromycin is on the WHO official list. Brand names are Arpimicin, Erymax, Erymin, Erythrocin, Erythroped, Tiloryth, and, formulated with other drugs for external use only, Benzamycin, Isotrexin and Zineryl.
erythromycinan antibiotic produced by a strain of STREPTOMYCES that inhibits protein synthesis, particularly in organisms which are Gram-positive (see GRAM'S STAIN).
erythromycinmacrolide; antimicrobial agent with similar spectrum of action to penicillin; effective against Gram-positive bacteria, including some penicillin-resistant staphylococci; indicated for treatment of cellulitis, impetigo and erysipelas in penicillin-sensitive individuals; dose = 250-500 mg orally every 6 hours

n an antibiotic produced by a strain of
S. erythroeus, only slightly effective against β-hemolytic streptococci (viridans group), and upper and lower respiratory tract, skin, and soft tissue infections of mild to moderate severity. It is no longer recommended by the American Heart Association and the American Dental Association for treatment of bacterial endocarditis in patients hypersensitive to penicillin.
