CLINICAL PHARMACOLOGY SECTION.

CLINICAL PHARMACOLOGY Microbiology Erythromycin inhibits protein synthesis without affecting nucleic acid synthesis. Erythromycin is usually active against the following organisms in vitro and in clinical infections: Streptococcus pyogenes (group -hemolytic), Alpha-hemolytic streptococci (viridans group); Staphylococcus aureus, including penicillinase-producing strains (methicillin-resistant staphylococci are uniformly resistant to erythromycin); Streptococcus pneumoniae; Mycoplasma pneumoniae (Eaton Agent, PPLO); Haemophilus influenzae (not all strains of this organism are susceptible at the erythromycin concentrations ordinarily achieved); Treponema pallidum; Corynebacterium diphtheriae; Neisseria gonorrhoeae; Chlamydia trachomatis.

INDICATIONS & USAGE SECTION.

INDICATIONS AND USAGE For the treatment of superficial ocular infections involving the conjunctiva and/or cornea caused by organisms susceptible to erythromycin. For prophylaxis of ophthalmia neonatorum due to N. gonorrhoeae or C. trachomatis. The effectiveness of erythromycin in the prevention of ophthalmia caused by penicillinase-producing N. gonorrhoeae is not established. For infants born to mothers with clinically apparent gonorrhea, intravenous or intramuscular injections of aqueous crystalline penicillin should be given; single dose of 50,000 units for term infants or 20,000 units for infants of low birth weight. Topical prophylaxis alone is inadequate for these infants.

PRECAUTIONS SECTION.

PRECAUTIONS General The use of antimicrobial agents may be associated with the overgrowth of non-susceptible organisms including fungi; in such case, antibiotic administration should be stopped and appropriate measures taken. Information for Patients: Avoid contaminating the applicator tip with material from the eye, fingers, or other source. Carcinogenesis, Mutagenesis, Impairment of Fertility: Two year oral studies conducted in rats with erythromycin did not provide evidence of tumorigenicity. Mutagenicity studies have not been conducted. No evidence of impaired fertility that appeared related to erythromycin was reported in animal studies.Pregnancy: Pregnancy Category B. Reproduction studies have been performed in rats, mice, and rabbits using erythromycin and its various salts and esters, at doses that were several multiples of the usual human dose. No evidence of harm to the fetus that appeared related to erythromycin was reported in these studies. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, the erythromycins should be used during pregnancy only if clearly needed.Nursing Mothers: Caution should be exercised when erythromycin is administered to nursing woman. Pediatric Use: See INDICATIONS AND USAGE and DOSAGE AND ADMINISTRATION.
