CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

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.

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. 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.

CONTRAINDICATIONS SECTION.

CONTRAINDICATIONS:. This drug is contraindicated in patients with history of hypersensitivity to erythromycin.

DESCRIPTION SECTION.

DESCRIPTION:. Erythromycin Ophthalmic Ointment belongs to the macrolide group of antibiotics. It is basic and readily forms salt when combined with an acid. The base, as crystals or powder, is slightly soluble in water, moderately soluble in ether, and readily soluble in alcohol or chloroform. Erythromycin ((3R, 4S, 5S, 6R, 7R, 9R, 11R, 12R, 13S, 14R)-4-[(2,6-dideoxy-3-C-methyl-3 O-methyl--L-ribo-hexopyranosyl)-oxy]-14-ethyl-7,12,13-trihydroxy- 3,5,7,9,11,13-hexamethyl-6-[[3,4,6-trideoxy-3-(dimethyl-amino)--D-xylo-hexopyranosyl]oxy]oxacyclotetradecane-2,10-dione)) is an antibiotic produced from strain of Streptomyces erythraeus. It has the following structural formula:Each gram contains Erythromycin USP mg in sterile ophthalmic base of mineral oil and white petrolatum.. Structural Formula.

GENERAL PRECAUTIONS SECTION.

General: The use of antimicrobial agents may be associated with the overgrowth of nonsusceptible organisms including fungi; in such case, antibiotic administration should be stopped and appropriate measures taken.

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.

INFORMATION FOR PATIENTS SECTION.

Information for Patients: Avoid contaminating the applicator tip with material from the eye, fingers, or other source.

MICROBIOLOGY SECTION.

General: The use of antimicrobial agents may be associated with the overgrowth of nonsusceptible 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: Teratogenic Effects: 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.. Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and younger patients.
