ERYTHROMYCIN ETHYLSUCCINATE

Macrolides [CS]; Decreased Sebaceous Gland Activity [PE]; Macrolide [EPC]; Macrolide Antimicrobial [EPC]

Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.

Drugs used for their effects on the gastrointestinal system, as to control gastric acidity, regulate gastrointestinal motility and water flow, and improve digestion.

Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins.

Substances that inhibit the growth or reproduction of BACTERIA.

ERYTHROMYCIN ETHYLSUCCINATE IS PARTIALLY DISSOCIATED IN INTESTINE; BOTH ERYTHROMYCIN & UNDISSOCIATED ESTER ARE ABSORBED &, IN THE BLOOD, THE ESTER IS HYDROLYZED TO RELEASE FREE ERYTHROMYCIN.

ERYTHROMYCIN ETHYLSUCCINATE...IS ADEQUATELY ABSORBED FOLLOWING ORAL ADMINISTRATION, PARTICULARLY WHEN THE STOMACH IS EMPTY. PEAK CONCENTRATIONS IN PLASMA ARE 1.5 UG/ML (0.5 UG/ML OF BASE) 1 TO 2 HR AFTER ADMINISTRATION OF A 500 MG TABLET.

IN PATIENTS, MEAN BILE LEVELS OF ERYTHROMYCIN WERE APPROXIMATELY 10 TIMES HIGHER THAN CORRESPONDING SERUM CONCN 1 HR AFTER IV (ERYTHROMYCIN LACTOBIONATE) & IM (ERYTHROMYCIN SUCCINATE) INJECTION.

IN HEALTHY ADULT SUBJECTS & IN ADULT PATIENTS WITH BRONCHIAL INFECTIONS, PHARMACOKINETICS OF VARIOUS FORMULATIONS OF ERYTHROMYCIN WERE STUDIED. ERYTHROMYCIN ETHYLSUCCINATE WAS BETTER THAN ERYTHROMYCIN STEARATE FOR ORAL TREATMENT IN THAT IT WAS RAPIDLY & CONSISTENTLY ABSORBED.

ERYTHROMYCIN ETHYLSUCCINATE INJECTION, USP (ERYTHROCIN ETHYLSUCCINATE-IM), CONTAINS 50 MG/ML IN 2- & 10-ML CONTAINERS FOR IM INJECTION. THIS PREPN INCL BUTYL AMINOBENZOATE (2%) AS LOCAL ANESTHETIC.

INCIDENCE OF ERYTHROMYCIN-RESISTANT STRAINS OF STAPH AUREUS HAS BEEN INCR; IN SOME HOSPITALS 50% OF STRAINS ARE NOT INHIBITED BY DRUG. OCCASIONAL STRAINS OF STREPTOCOCCUS PYOGENES & STREP (D) PNEUMONIAE RESISTANT TO DRUG HAVE BEEN RECOVERED FROM PT. /ERYTHROMYCIN/
