BACTRIM DS SUMMARY

BACTRIM™
sulfamethoxazole and trimethoprim DS
(double strength) tablets and tablets USP

BACTRIM (sulfamethoxazole and trimethoprim) is a synthetic antibacterial combination product available in DS (double strength) tablets, each containing 800 mg sulfamethoxazole and 160 mg trimethoprim; in tablets, each containing 400 mg sulfamethoxazole and 80 mg trimethoprim for oral administration.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Bactrim (sulfamethoxazole and trimethoprim) tablets and other antibacterial drugs, Bactrim (sulfamethoxazole and trimethoprim) 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 empiric selection of therapy.

BACTRIM (sulfamethoxazole and trimethoprim) is indicated for the following:

Urinary Tract Infections

For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and Proteus vulgaris. It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination.

Acute Otitis Media

For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when in the judgment of the physician sulfamethoxazole and trimethoprim offers some advantage over the use of other antimicrobial agents. To date, there are limited data on the safety of repeated use of BACTRIM in pediatric patients under two years of age. BACTRIM is not indicated for prophylactic or prolonged administration in otitis media at any age.

Acute Exacerbations of Chronic Bronchitis in Adults

For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when in the judgment of the physician BACTRIM offers some advantage over the use of a single antimicrobial agent.

Shigellosis

For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated.

Pneumocystis Carinii Pneumonia

For the treatment of documented Pneumocystis carinii pneumonia and for prophylaxis against Pneumocystis carinii pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis carinii pneumonia.

Traveler's Diarrhea in Adults

For the treatment of traveler's diarrhea due to susceptible strains of enterotoxigenic E. coli.

Published Studies Related to Bactrim DS (Sulfamethoxazole / Trimethoprim)

Randomized controlled trial of trimethoprim-sulfamethoxazole for uncomplicated skin abscesses in patients at risk for community-associated methicillin-resistant Staphylococcus aureus infection. [2010.09]
STUDY OBJECTIVE: Community-associated methicillin-resistant Staphylococcus aureus is now the leading cause of uncomplicated skin abscesses in the United States, and the role of antibiotics is controversial. We evaluate whether trimethoprim-sulfamethoxazole reduces the rate of treatment failures during the 7 days after incision and drainage and whether it reduces new lesion formation within 30 days... CONCLUSION: After the incision and drainage of uncomplicated abscesses in adults, treatment with trimethoprim-sulfamethoxazole does not reduce treatment failure but may decrease the formation of subsequent lesions.

Standard versus newer antibacterial agents in the treatment of severe acute exacerbation of chronic obstructive pulmonary disease: a randomized trial of trimethoprim-sulfamethoxazole versus ciprofloxacin. [2010.07.15]
BACKGROUND. Although the use of antibiotics in the treatment of acute exacerbation of chronic obstructive pulmonary disease (COPD) is largely accepted, controversy remains regarding whether the choice of antibiotic has any impact on outcome.

Trimethopim-sulfamethoxazole compared with benzathine penicillin for treatment of impetigo in Aboriginal children: a pilot randomised controlled trial. [2010.03]
We conducted a pilot randomized controlled trial comparing trimethoprim-sulfamethoxazole to benzathine penicillin for treatment of impetigo in Aboriginal children. Treatment was successful in 7 of 7 children treated with trimethoprim-sulfamethoxazole and 5 of 6 treated with benzathine penicillin.Trimethoprim-sulfamethoxazole achieved microbiological clearance and healing of sores from which beta-hemolytic streptococci and community-associated methicillin-resistant Staphylococcus aureus were initially cultured.

Randomized controlled trial of trimethoprim-sulfamethoxazole for uncomplicated skin abscesses in patients at risk for community-associated methicillin-resistant Staphylococcus aureus infection. [2010]

Effect of long-term trimethoprim/sulfamethoxazole treatment on resistance and integron prevalence in the intestinal flora: a randomized, double-blind, placebo-controlled trial in children. [2009.05]
OBJECTIVES: The aim of this study was to test the hypothesis that trimethoprim/sulfamethoxazole selects for integron-positive and multidrug-resistant Enterobacteriaceae in the intestinal flora... CONCLUSIONS: Initially, trimethoprim/sulfamethoxazole usage was strongly associated with the appearance of integron-positive (multi)drug-resistant Enterobacteriaceae in the intestinal flora. After prolonged exposure to trimethoprim/sulfamethoxazole, however, this population of Enterobacteriaceae was substituted by a population with non-integron-associated resistance mechanisms. After trimethoprim/sulfamethoxazole was discontinued, susceptibility rates to all antibiotics returned to baseline levels.

Clinical Trials Related to Bactrim DS (Sulfamethoxazole / Trimethoprim)

Study to Test the Validity of the Treatment of Idiopathic Pulmonary Fibrosis With Cotrimoxazole [Not yet recruiting]
First study to test the validity of the treatment of idiopathic pulmonary fibrosis, which causes inflammation and fibrosis (scarring) of the lung tissue, with cotrimoxazole.

Cotrimoxazole may improve the clinical course of the disease through eradication of Pneumocystis jiroveci colonization and other mechanisms as inhibiting the activation of alveolar macrophages and producing alterations in the surfactant system which favours the persistent activation of the inflammatory response and the development of pulmonary fibrosis.

Cotrimoxazole Prophylaxis in Severely Malnourished Children [Recruiting]
This trial aims to test the hypothesis that mortality among Kenyan children with severe malnutrition following initial stabilisation is due to ongoing vulnerability to infectious disease, and that co-trimoxazole prophylaxis will reduce mortality.

The objective is to conduct a randomized, double blind, placebo-controlled trial of cotrimoxazole prophylaxis for 6 months among HIV-uninfected children with severe malnutrition following stabilization. The primary outcome will be survival at one year. Secondary outcomes are toxicity, survival at two years, growth, hospitalisation and microbial resistance and ecology.

Cotrimoxazole has striking protective efficacy against mortality among children with HIV, despite not altering the underlying immune deficiency. It is hypothesised that co-trimoxazole prophylaxis will have a similar effect in children immunocompromised because of severe malnutrition. Worldwide, severe malnutrition is commoner than HIV in childhood and co-trimoxazole is cheap and widely available, making it easily translatable to policy.

Study of New Antibiotic Regimen for the Treatment of Uncomplicated Cellulitis in Emergency Department Patients [Recruiting]
The primary aim of this study is to quantify the effectiveness of Bactrim as additional therapy for the treatment of uncomplicated cellulitis in adults, by comparing: standard therapy plus Bactrim, versus standard therapy plus placebo.

The primary hypothesis of this study is that, in light of increasing CA-MRSA prevalence, subjects treated with standard therapy plus Bactrim will have higher cure rates than those treated with standard therapy plus placebo.

Co-trimoxazole as Maintenance Therapy for Meliodosis [Not yet recruiting]
This is a randomised, open-labelled, controlled trial to compare the efficacy and effectiveness on relapse-free rate of 12-week versus 20-week oral eradication treatment of melioidosis. The study population includes 800 patients with culture-confirmed melioidosis whom intravenous intensive antibiotics and 12 weeks of oral eradication therapy have been completed. Patients will be randomised to either stop the eradication treatment or continue current oral treatment for 8 more weeks. The study aim to optimise the regimen used to treat melioidosis for better compliance and reducing unnecessary use of antibiotics.

Cotrimoxazole Versus Vancomycin for Invasive Methicillin-resistant Staphylococcus Aureus Infections [Recruiting]
Methicillin-resistant Staphylococcus aureus (SA) is a major pathogen causing mainly health-care associated infections and, lately, also community acquired infections. Few treatment choices exist to treat these infections. The currently recommended antibiotics for these infections are glycopeptides (vancomycin or teicoplanin). Glycopeptide treatment hs several disadvantages. It is a last resort antibiotic family that should be reserved for the future; Vancomycin is less effective that beta-lactam drugs for SA infections susceptible to both agents; treatment can only be given intravenously; and use of vancomycin has led to the development of SA strains with partial or complete resistance to vancomycin. Cotrimoxazole is an old antibiotic active against most strains of MRSA, depending on local epidemiology.

Study hypothesis: The purpose of this study is to show that cotrimoxazole is as effective as treatment with vancomycin for invasive MRSA infections.

We plan a randomized controlled trial comparing treatment with cotrimoxazole vs. vancomycin for invasive MRSA infections. The primary efficacy outcome we will assess will be Improvement or cure with or without antibiotic modifications, defined as: survival at 7 days post randomization with resolution of fever (<38 for two consecutive days) and resolution of hypotension (>90 systolic without need for vasopressor support); and physician's assessment that the primary infection was improved or cured. The primary safety outcome will be all-cause 30-day survival.
