MEDICATION (VET): In veterinary medicine, /erythromycin/ is used the treatment of clinical and subclinical mastitis in lactating cows, for the treatment of infectious diseases due to erythromycin-sensitive bacteria (cattle, sheep, swine, poultry) and for the treatment of chronic respiratory diseases due to mycoplasma in poultry.
Erythromycin is used as an alternative agent in the treatment of anthrax. Parenteral penicillins generally have been considered the drugs of choice for the treatment of naturally occurring or endemic anthrax caused by susceptible strains of Bacillus anthracis, including clinically apparent GI, inhalational, or meningeal anthrax and anthrax septicemia, although IV ciprofloxacin or IV doxycycline also are recommended. Erythromycin is suggested as an alternative to penicillin G for the treatment of naturally occurring or endemic anthrax in patients hypersensitive to penicillins. ./NOT included in US product label/

Erythromycin is used topically in the treatment of acne vulgaris. Therapy of acne vulgaris must be individualized and frequently modified depending on the types of acne lesions which predominate and the response to therapy. Topical anti-infectives, including erythromycin, are generally effective in the treatment of mild to moderate inflammatory acne. However, use of topical anti-infectives as monotherapy may lead to bacterial resistance; this resistance is associated with decreased clinical efficacy. Topical erythromycin is particularly useful when used with benzoyl peroxide or topical retinoids. Results of clinical studies indicate that combination therapy results in a reduction in total lesion counts of 50 to 70%. /Included in US product label/

Some commercially available formulations of erythromycin lactobionate powder for injection contain benzyl alcohol as a preservative. Although a causal relationship has not been established, administration of injections preserved with benzyl alcohol has been associated with toxicity in neonates. Toxicity appears to have resulted from administration of large amounts (i.e., about 100-400 mg/kg daily) of benzyl alcohol in these neonates. Although use of drugs preserved with benzyl alcohol should be avoided in neonates whenever possible, the American Academy of Pediatrics states that the presence of small amounts of the preservative in a commercially available injection should not proscribe its use when indicated in neonates. /Erythromycin lactobionate/

In several neonates with infections caused by Ureaplasma urealyticum who received IV administration of erythromycin lactobionate, adverse cardiac effects (e.g., bradycardia, hypotension, cardiac arrest, arrhythmias) requiring cardiopulmonary resuscitation have been reported. Some clinicians state that these adverse effects may depend on serum concentration and/or infusion rate of the drug. It has been suggested that prolonged IV infusion of erythromycin lactobionate (e.g., over 60 minutes) may reduce such adverse cardiac effects. However, it has been suggested that certain individuals may be at increased risk of developing erythromycin-induced adverse cardiac effects and that decreasing the rate of IV infusion may decrease but not eliminate the risk of such effects. Further study is needed to determine the pharmacokinetics and safety of erythromycin lactobionate in neonates. /Erythromycin lactobionate/

Erythromycin is indicated in the treatment of infections caused by susceptible strains of various bacteria. The indications for erythromycin have been summarized by body system below: **Respiratory infections** Mild to moderate upper respiratory tract infections caused by Streptococcus pyogenes, Streptococcus pneumoniae, or Haemophilus influenzae (when used concomitantly with appropriate doses of sulfonamides) can be treated with erythromycin. Mild to moderate lower-respiratory tract infections due to susceptible strains of Streptococcus pneumoniae or Streptococcus pyogenes may also be treated. Erythromycin treats listeriosis caused by Listeria monocytogenes may also be treated with erythromycin. Erythromycin is indicated to treat pertussis (whooping cough) caused by Bordetella pertussis. It is effective in eliminating the causative organism from the nasopharynx of infected individuals, rendering them noninfectious. Clinical studies suggest that erythromycin may aid in the prevention of pertussis infection for individuals who have been exposed to the bacteria. Respiratory tract infections due to Mycoplasma pneumoniae may also be treated with erythromycin. Despite the fact that no controlled clinical efficacy studies have been conducted to this date, in vitro and certain preliminary clinical study results indicate that erythromycin may be an effective treatment in Legionnaires Disease. Finally, erythromycin is indicated to treat diphtheria and other infections due to Corynebacterium diphtheriae, as an adjunct to antitoxin, to prevent carrier status and to eradicate the organism in existing carriers. In addition to the prevention of diphtheria, erythromycin can be used to prevent rheumatic fever in penicillin intolerant patients. **Skin infections** Mild to moderate skin or skin structure infections caused by Streptococcus pyogenes or Staphylococcus aureus may be treated with erythromycin, however, resistant staphylococcal organisms may emerge. Erythromycin can also be used to treat erythrasma, an infectious condition caused by Corynebacterium minutissimum. **Gastrointestinal infections** Intestinal amebiasis caused by Entamoeba histolytica can be treated with oral erythromycin. Extraenteric amebiasis warrants treatment with other antimicrobial drugs. **Genital infections/STIs** Erythromycin can be used as an alternative drug in treating acute pelvic inflammatory disease caused by N. gonorrheae in female patients who have demonstrated hypersensitivity or intolerance to penicillin. Syphilis, caused by Treponema pallidum, can be treated with erythromycin. It serves as an alternative treatment for primary syphilis in patients who have demonstrated penicillin hypersensitivity. Erythromycin can also be used in the primary stage of primary syphilis. Another approved indication of erythromycin is to treat chlamydial infections that cause conjunctivitis of the newborn, pneumonia of infancy, and urogenital infections occurring in pregnancy. It is indicated as an alternative option to tetracyclines for the treatment of uncomplicated rectal, urethral and endocervical infections in adults caused by Chlamydia trachomatis. Erythromycin can be used in nongonococcal urethritis can be used when tetracyclines cannot be administered. Finally, erythromycin is indicated to treat nongonococcal urethritis due to Ureaplasma urealyticum.
Macrolides, such as erythromycin, stop bacterial growth by inhibiting protein synthesis and translation, treating bacterial infections. Erythromycin does not exert effects on nucleic acid synthesis. This drug has been shown to be active against most strains of the following microorganisms, effectively treating both in vitro and clinical infections. Despite this, it is important to perform bacterial susceptibility testing before administering this antibiotic, as resistance is a common issue that may affect treatment. **A note on antimicrobial resistance, pseudomembranous colitis, and hepatotoxicity** Many strains of Haemophilus influenzae are resistant to erythromycin alone but are found to be susceptible to erythromycin and sulfonamides used in combination. It is important to note that Staphylococci that are resistant to erythromycin may emerge during erythromycin and/or sulfonamide therapy. Pseudomembranous colitis has been reported with most antibacterial agents, including erythromycin, and may range in severity from mild to life-threatening. Therefore, the physician should consider this diagnosis in patients with diarrhea after the administration of antibacterial agents. Erythromycin can cause hepatic dysfunction, cholestatic jaundice, and abnormal liver transaminases, particularly when erythromycin estolate is administered.

Absorption
Orally administered erythromycin is readily absorbed. Food intake does not appear to exert effects on serum concentrations of erythromycin. Some interindividual variation exists in terms of erythromycin absorption, which may impact absorption to varying degrees. The Cmax of erythromycin is 1.8 mcg/L and the Tmax is 1.2 hours. The serum AUC of erythromycin after the administration of a 500mg oral dose was 7.33.9 mg.h/l in one pharmacokinetic study. Erythromycin is well known for a bioavailability that is variable (18-45%) after oral administration and its susceptibility to broken down under acidic conditions.
Route of Elimination
In patients with normal liver function, erythromycin concentrates in the liver and is then excreted in the bile.Under 5% of the orally administered dose of erythromycin is found excreted in the urine. A high percentage of absorbed erythromycin is not accounted for, but is likely metabolized.
Volume of Distribution
Erythromycin is found in most body fluids and accumulates in leucocytes and inflammatory liquid. Spinal fluid concentrations of erythromycin are low, however, the diffusion of erythromycin through the blood-brain barrier increases in meningitis, likely due to the presence of inflamed tissues which are easily penetrated. Erythromycin crosses the placenta.
Clearance
The clearance of erythromycin in healthy subjects was 0.53 0.13 l/h/kg after a 125mg intravenous dose. In a clinical study of healthy patients and patients with liver cirrhosis, clearance of erythromycin was significantly reduced in those with severe liver cirrhosis. The clearance in cirrhotic patients was 42.2 10.1 l h1 versus 113.2 44.2 l h-1 in healthy patients.
Absorption of orally administered erythromycins occurs mainly in the duodenum. The bioavailability of the drugs is variable and depends on several factors including the particular erythromycin derivative, the formulation of the dosage form administered, acid stability of the derivative, presence of food in the GI tract, and gastric emptying time.
American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 234
Erythromycin is rather slowly absorbed after oral administration. peak serum concentrations ranged from 0.1 to 4.8 ug/mL according to the form and the coating of erythromycin administered. The oral absorption is less that 50% and erythromycin is degraded by gastric acid. It is absorbed in the small intestine (mainly in duodenum for humans) as erythromycin base.
Erythromycin diffuses readily into intracellular fluids, achieving antibacterial activity in essentially all sites except the brain and CSF. Erythromycin penetrates into prostatic fluid, achieving concentrations approximately 40% of those in plasma. Concentrations in middle ear exudate reach only 50% of serum concentrations and thus may be inadequate for the treatment of otitis media caused by H. influenzae. Protein binding is approximately 70% to 80% for erythromycin base and even higher, 96%, for the estolate. Erythromycin traverses the placenta, and drug concentrations in fetal plasma are about 5% to 20% of those in the maternal circulation. Concentrations in breast milk are 50% of those in serum.

In an in vitro model using human skin, erythromycin was absorbed into the stratum corneum following topical application of 10-20 mg of the drug in a vehicle containing dimethylacetamide and 95% alcohol. The drug does not appear to be absorbed systemically following twice daily application of a 2% solution of the drug in a vehicle containing 77% alcohol and polyethylene glycol and acetone. It is not known if erythromycin is absorbed from intact or denuded skin, wounds, or mucous membranes following topical application of an ointment containing the drug.

Hepatic first-pass metabolism contributes significantly to erythromycin metabolism after an oral dose. Erythromycin is partially metabolized by CYP3A4 enzyme to N-desmethylerythromycin. Erythromycin is also hydrolyzed to _anhydro_ forms (anhydroerythromycin [AHE] and other metabolites), and this process is promoted by acidic conditions. AHE is inactive against microbes but inhibits hepatic drug oxidation and is therefore considered to be an important contributor to erythromycin drug-drug interactions.
Twenty hours after an oral administration of 10 mg erythromycin to rats, about 37-43% of the administered radioactivity was recovered in the intestinal tract plus feces, 27.2 to 36.1% in the urine, 21-29% in the expired air. It was rapidly metabolized in the liver, mainly through demethylation process, and excreted in the bile as des-N-methyl-erythromycin, the major metabolite present only in the bile and in the intestinal contents of rats. The isotropic methyl group was eliminated in the expired air as CO2.
The elimination half-life of oral erythromycin was 3.5 hours according to one study and ranged between 2.4-3.1 hours in another study. Repetitive dosing of erythromycin leads to increased elimination half-life.
... The serum elimination half-life of erythromycin is approximately 1.6 hours.

The serum half-life in normal subjects is 2 hours and in anuric subjects, 4-6 hours.

In order to replicate, bacteria require a specific process of protein synthesis, enabled by ribosomal proteins. Erythromycin acts by inhibition of protein synthesis by binding to the 23S ribosomal RNA molecule in the 50S subunit of ribosomes in susceptible bacterial organisms. It stops bacterial protein synthesis by inhibiting the transpeptidation/translocation step of protein synthesis and by inhibiting the assembly of the 50S ribosomal subunit. This results in the control of various bacterial infections. The strong affinity of macrolides, including erythromycin, for bacterial ribosomes, supports their broadspectrum antibacterial activities.
Macrolide antibiotics are bacteriostatic agents that inhibit protein synthesis by binding reversibly to 50S ribosomal subunits of sensitive microorganisms, at or very near the site that binds chloramphenicol. Erythromycin does not inhibit peptide bond formation per se, but rather inhibits the translocation step wherein a newly synthesized peptidyl tRNA molecule moves from the acceptor site on the ribosome to the peptidyl donor site. Gram-positive bacteria accumulate about 100 times more erythromycin than do gram-negative bacteria. Cells are considerably more permeable to the un-ionized form of the drug, which probably explains the increased antimicrobial activity at alkaline pH.

... /Erythromycin/ inhibits the growth of susceptible organisms (principally Propionibacterium acnes) on the surface of the skin and reduces the concn of free fatty acids in sebum ... The reduction in free fatty acids in sebum may be an indirect result of the inhibition of lipase-producing organisms which convert triglycerides into free fatty acids or may be a direct result of interference with lipase production in these organisms. /In acne treatment regimens/

Although stromal-derived factor-1 (SDF-1) via its cognate receptor CXCR4 is assumed to play a critical role in migration of endothelial cells during new vessel formation after tissue injury, CXCR4 expression on endothelial cells is strictly regulated. Erythromycin (EM), a 14-membered ring macrolide, has an anti-inflammatory effect that may account for its clinical benefit in the treatment of chronic inflammatory diseases. However, the effects of EM on endothelial cells and especially their expression of CXCR4 have not been fully evaluated. In this study, we demonstrated that EM markedly induced CXCR4 surface expression on microvascular endothelial cells in vitro and lung capillary endothelial cells in vivo. This ability to induce CXCR4 surface expression on endothelial cells was restricted to 14-membered ring macrolides and was not observed in other antibiotics including a 16-membered ring macrolide, josamycin. Furthermore, this EM-induced expression of CXCR4 on endothelial cells was functionally significant as demonstrated by chemotaxis assays in vitro. These findings suggest that EM-induced CXCR4 surface expression on endothelial cells may promote migration of CXCR4-expressing endothelial cells into sites of tissue injury, which may be associated with the known anti-inflammatory activity of this macrolide.
