(erythromycin stearate tablets, USP)
ERYTHROCIN STEARATE Filmtab tablets (erythromycin stearate tablets, USP) are an antibacterial product containing the stearate salt of erythromycin in a unique film coating. Erythromycin is produced by a strain of Saccharopolyspora erythraea (formerly Streptomyces erythraeus) and belongs to the macrolide group of antibiotics. It is basic and readily forms salts with acids. Erythromycin is a white to off-white powder, slightly soluble in water, and soluble in alcohol, chloroform, and ether.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of ERYTHROCIN STEARATE Filmtab tablets and other antibacterial drugs, ERYTHROCIN STEARATE Filmtab tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
ERYTHROCIN STEARATE tablets are indicated in the treatment of infections caused by susceptible strains of the designated microorganisms in the diseases listed below:
Upper respiratory tract infections of mild to moderate degree caused by Streptococcus pyogenes; Streptococcus pneumoniae; Haemophilus influenzae (when used concomitantly with adequate doses of sulfonamides, since many strains of H. influenzae are not susceptible to the erythromycin concentrations ordinarily achieved). (See appropriate sulfonamide labeling for prescribing information.)
Lower respiratory tract infections of mild to moderate severity caused by Streptococcus pyogenes or Streptococcus pneumoniae.
Listeriosis caused by Listeria monocytogenes.
Respiratory tract infections due to Mycoplasma pneumoniae.
Skin and skin structure infections of mild to moderate severity caused by Streptococcus pyogenes or Staphylococcus aureus (resistant staphylococci may emerge during treatment).
Pertussis (whooping cough) caused by Bordetella pertussis. Erythromycin is effective in eliminating the organism from the nasopharynx of infected individuals, rendering them noninfectious. Some clinical studies suggest that erythromycin may be helpful in the prophylaxis of pertussis in exposed susceptible individuals.
Diphtheria: Infections due to Corynebacterium diphtheriae, as an adjunct to antitoxin, to prevent establishment of carriers and to eradicate the organism in carriers.
Erythrasma - In the treatment of infections due to Corynebacterium minutissimum.
Intestinal amebiasis caused by Entamoeba histolytica (oral erythromycins only). Extraenteric amebiasis requires treatment with other agents.
Acute Pelvic Inflammatory Disease Caused by Neisseria gonorrhoeae: Erythrocin® Lactobionate-I.V. (erythromycin lactobionate for injection, USP) followed by erythromycin base orally, as an alternative drug in treatment of acute pelvic inflammatory disease caused by N. gonorrhoeae in female patients with a history of sensitivity to penicillin. Patients should have a serologic test for syphilis before receiving erythromycin as treatment of gonorrhea and a follow-up serologic test for syphilis after 3 months.
Erythromycins are Indicated for Treatment of the Following Infections Caused by Chlamydia trachomatis: Conjunctivitis of the newborn, pneumonia of infancy, and urogenital infections during pregnancy. When tetracyclines are contraindicated or not tolerated, erythromycin is indicated for the treatment of uncomplicated urethral, endocervical, or rectal infections in adults due to Chlamydia trachomatis.
When tetracyclines are contraindicated or not tolerated, erythromycin is indicated for the treatment of nongonococcal urethritis caused by Ureaplasma urealyticum.
Primary syphilis caused by Treponema pallidum. Erythromycin (oral forms only) is an alternative choice of treatment for primary syphilis in patients allergic to the penicillins. In treatment of primary syphilis, spinal fluid should be examined before treatment and as part of the follow-up after therapy.
Legionnaires' Disease caused by Legionella pneumophila. Although no controlled clinical efficacy studies have been conducted, in vitro and limited preliminary clinical data suggest that erythromycin may be effective in treating Legionnaires' Disease.
Prevention of Initial Attacks of Rheumatic Fever
Penicillin is considered by the American Heart Association to be the drug of choice in the prevention of initial attacks of rheumatic fever (treatment of Streptococcus pyogenes infections of the upper respiratory tract e.g., tonsillitis, or pharyngitis).3 Erythromycin is indicated for the treatment of penicillin-allergic patients. The therapeutic dose should be administered for ten days.
Prevention of Recurrent Attacks of Rheumatic Fever
Penicillin or sulfonamides are considered by the American Heart Association to be the drugs of choice in the prevention of recurrent attacks of rheumatic fever. In patients who are allergic to penicillin and sulfonamides, oral erythromycin is recommended by the American Heart Association in the long-term prophylaxis of streptococcal pharyngitis (for the prevention of recurrent attacks of rheumatic fever).3

Clinical Trials Related to Erythrocin (Erythromycin)
The Effect of Concomitant Administration of Erythromycin and Diltiazem on CYP3A Activity in Healthy Volunteers [Completed]
We, the researchers at the Indiana University School of Medicine, are doing this study to
better understand how the effects of certain medications are altered when taken
simultaneously, or in combination with each other. We will also look at how each volunteer's
genes (DNA) may affect the way these medications are metabolized.
We will test the hypothesis that the extent of drug-drug interaction caused by the
combination of erythromycin and diltiazem is not predictable from the extent of interaction
produced by each inhibitor alone. Specifically we will test the hypothesis that the
combination of erythromycin and diltiazem will cause a greater decrease in midazolam
intravenous and oral clearance than the sum of the decreases caused by each inhibitor alone.
Comparison of Two Macrolides, Azithromycin and Erythromycin, for Symptomatic Treatment of Gastroparesis [Recruiting]
Erythromycin is effectively used in the treatment of Gastroparesis (GP) patients. In
susceptible patients however, it has been associated with sudden cardiac death due to
prolongation of QT intervals and subsequent cardiac risks through its interaction some other
drugs. Azithromycin (AZI) is a macrolide antibiotic but does not have the mentioned druf
interactions , has fewer gastrointestinal side effects, and fewer risks of QT prolongation
and cardiac arrhythmias. Consequently, AZI avoids drawbacks of dosing with erythromycin and
may be preferred as a prokinetic agent in patients on other concomitant medications.
We hope to demonstrate the effectiveness of Azithromycin (AZI) as compared to Erythromycin
in the treatment of Gastroparesis (GP), and later, form the framework for larger
randomized-controlled parallel studies to investigate use of AZI for treatment of GP.
Our novel hypothesis is to determine whether AZI can be used to treat GP.
A Study of Erythromycin and Rivaroxaban in Study Participants With Normal and Reduced Kidney Function [Recruiting]
The purpose of this study is to evaluate the pharmacokinetics and pharmacodynamics of
rivaroxaban when administered with erythromycin to study participants with mild or moderate
renal impairment compared to the pharmacokinetics and pharmacodynamics of rivaroxaban
administered to study participants with normal renal function.
Methylnaltrexone vs Erythromycin for Facilitating Gastric Emptying Time in Critically Ill Patients [Recruiting]
42 patients admitted in ICU with intolerance to enteral feeding (GRV more than 250 ml) are
recruited. All patients enter a primary acetaminophen absorption test study as baseline.
Serum levels of acetaminophen will be measured by florescence polarization method at
15,30,45,60,90,120,180,240,480 minutes after enteral administration of 975 mg acetaminophen.
Then the patients will be randomized to methylnaltrexone or erythromycin group. Another
acetaminophen absorption test with the same schedule will be done after the last dose of
each drug. The area under the curve for acetaminophen blood level will be used to compare the
effect of two studied drugs on gastric emptying time.
Effect of Erythromycin Before Endoscopy of Patients With Subtotal Gastrectomy (STG), High Risk of Gastric Stasis [Recruiting]
Erythromycin has a prokinetic effect through Motilin receptor. It evokes migrating motor
complex with longer and stronger contraction.
In patients with upper gastrointestinal bleeding, It has been shown that erythromycin could
clear the stomach of blood, so visual examination could be improved.
Frequent food stasis is encounted when we examine patients with subtotal gastrectomy. It is
postulated that erythromycin reduce food stasis and help to improve endoscopy in these
