Bicillin L-A (Penicillin G Benzathine) - Summary

 
 



WARNING: NOT FOR INTRAVENOUS USE. DO NOT INJECT INTRAVENOUSLY OR ADMIX WITH OTHER INTRAVENOUS SOLUTIONS. THERE HAVE BEEN REPORTS OF INADVERTENT INTRAVENOUS ADMINISTRATION OF PENCILLIN G BENZATHINE WHICH HAS BEEN ASSOCIATED WITH CARDIORESPIRATORY ARREST AND DEATH. Prior to administration of this drug, carefully read the WARNINGS, ADVERSE REACTIONS, and DOSAGE AND ADMINISTRATION sections of the labeling.

 

BICILLIN L-A SUMMARY

Bicillin L-A (penicillin G benzathine suspension) is prepared by the reaction of dibenzylethylene diamine with two molecules of penicillin G.

Intramuscular penicillin G benzathine is indicated in the treatment of infections due to penicillin-G-sensitive microorganisms that are susceptible to the low and very prolonged serum levels common to this particular dosage form. Therapy should be guided by bacteriological studies (including sensitivity tests) and by clinical response.

The following infections will usually respond to adequate dosage of intramuscular penicillin G benzathine:

Mild-to-moderate infections of the upper respiratory tract due to susceptible streptococci.

Venereal infections -- Syphilis, yaws, bejel, and pinta.

Medical Conditions in which Penicillin G Benzathine Therapy is Indicated as Prophylaxis:

Rheumatic fever and/or chorea-- Prophylaxis with penicillin G benzathine has proven effective in preventing recurrence of these conditions. It has also been used as follow-up prophylactic therapy for rheumatic heart disease and acute glomerulonephritis.

NEWS HIGHLIGHTS

Published Studies Related to Bicillin L-A (Penicillin G)

Treatment of streptococcal pharyngitis with once-daily amoxicillin versus intramuscular benzathine penicillin G in low-resource settings: a randomized controlled trial. [2011.06]
BACKGROUND: Primary prevention of acute rheumatic fever is achieved by proper antibiotic treatment of group A beta -hemolytic streptococcal (GAS) pharyngitis... CONCLUSION: If compliance is a major issue, a single dose of IM BPG may be preferable for treatment of GAS pharyngitis.

Administration of perioperative penicillin reduces postoperative serum amyloid a response in horses being castrated standing. [2010.07]
OBJECTIVES: To compare postoperative inflammatory responses in horses administered perioperative procaine penicillin and those not administered penicillin using acute phase protein serum amyloid A (SAA) as a marker of inflammation. STUDY DESIGN: Randomized clinical trial. ANIMALS: Stallions (n=50) castrated under field conditions... CONCLUSIONS: Perioperative antimicrobial therapy reduced the postoperative SAA response, suggesting that bacteria were present in the surgical wound and contributed to inflammation after castration. Horses with elevated preoperative SAA concentrations developed infectious complications more often than horses with normal preoperative SAA concentrations. CLINICAL RELEVANCE: Administration of antimicrobials may be important in horses being castrated standing under field conditions. Increased SAA concentrations seem to be an indicator of increased surgical risk in horses and may be useful before elective surgery for planning.

A phase III equivalence trial of azithromycin versus benzathine penicillin for treatment of early syphilis. [2010.06.01]
BACKGROUND: Syphilis remains an important source of morbidity worldwide. Long-acting penicillin is the only therapy currently recommended for syphilis in much of the world. Because of hesitation to use penicillin for fear of anaphylaxis, there is a need for an effective, well-tolerated alternative to penicillin for syphilis therapy... CONCLUSIONS: In this trial, the efficacy of azithromycin at a dosage of 2.0 g administered orally was equivalent to that of benzathine penicillin G for the treatment of early syphilis in persons without HIV infection.

Comparison of ampicillin plus gentamicin vs. penicillin plus gentamicin in empiric treatment of neonates at risk of early onset sepsis. [2010.05]
AIM: We aimed to compare the clinical efficacy of ampicillin (AMP) vs. penicillin (PEN) both combined with gentamicin in the empirical treatment of neonates at risk of early onset neonatal sepsis (EOS)... CONCLUSIONS: AMP and PEN combined with gentamicin have similar effectiveness in the empiric treatment of suspected neonatal EOS.

Evaluation of penicillin G potassium troches in the treatment of minor recurrent aphthous ulceration in a Chinese cohort: a randomized, double-blinded, placebo and no-treatment-controlled, multicenter clinical trial. [2010.04]
CONCLUSIONS: Penicillin G potassium troches are effective in reducing ulcer size and alleviating ulcer pain of the patients in the treatment of a single episode of MiRAU in this Chinese cohort. Few adverse effects were observed with this therapeutic approach. Copyright 2010 Mosby, Inc. All rights reserved.

Clinical Trials Related to Bicillin L-A (Penicillin G)

Bicillin L-A vs Placebo for the Treatment of Chronic, Plaque-Type Psoriasis Unresponsive to Topical Medications [Recruiting]
The purpose of this study is to determine the efficacy for Bicillin L-A, administered intramuscularly in a dose of 2. 4 million units every three (3) weeks, for the treatment of chronic, plaque-type psoriasis unresponsive to topical medications or when other systemic therapies are contraindicated.

Amoxicillin Versus Benzyl Penicillin for Treatment of Children Hospitalised With Severe Pneumonia [Recruiting]
This study seeks to determine whether clinical outcome following initial treatment of severe pneumonia with oral amoxicillin is as effective as the current standard benzyl penicillin. The study will also provide an estimate of the proportion of Kenyan children with severe pneumonia who fail treatment with a single antibiotic.

Azithromycin/Bicillin Syphilis [Active, not recruiting]
The purpose of this study is to determine if Azithromycin, a drug approved for treatment of other infections, is as affective for syphilis therapy is as the usual treatment. Approximately 600 healthy adults, who are HIV-negative, age 18 to 55 years of age with primary, secondary or early latent syphilis, will be participating in this research study. Volunteers will be enrolled in 4 cities of the United States and in Madagascar. Participants will be chosen randomly (by chance) to receive one of 2 study drugs: Benzathine Penicillin given as one dose (2 shots in the buttocks) or 4 tablets of Azithromycin. Over 2 years, 10 visits are required. Procedures will include blood samples, physical exam, and swabs of sores. For subjects who report history of Penicillin allergy will be given either 2. 0 g of oral Azithromycin or 100 mg Doxycycline taken orally, twice a day for 14 days.

Simplified Antibiotic Therapy for Sepsis in Young Infants [Recruiting]
This trial evaluates primary care clinic-based simplified antibiotic therapy options for young infants, 0-59 days old in high neonatal mortality settings in peri-urban Karachi where hospital referral is frequently refused by families.

A Pilot Study Evaluating Penicillin G and Ceftriaxone as Therapies for Presumed Neurosyphilis in HIV Seropositive Individuals [Completed]
To provide information on the response of HIV infected, neurosyphilis patients to the currently recommended treatment for neurosyphilis; to determine whether possible co-infection with both HIV and syphilis makes more difficult the diagnosis of syphilis; to explore the usefulness of an alternative treatment which, if effective, would permit outpatient treatment for neurosyphilis that until now required prolonged hospitalization.

Studies suggest that syphilis treatment failures may be more common in HIV infected patients than in patients without HIV infection and that treatment failures occur due to and/or are displayed as central nervous system (CNS) involvement. Very little is known about the best treatment course for neurosyphilis in patients who are also infected with HIV.
