Septra (Trimethoprim / Sulfamethoxazole) - Summary

SEPTRA SUMMARY

SEPTRA (trimethoprim and sulfamethoxazole) is a synthetic antibacterial combination product.

SEPTRA 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, Kelbsiella 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, SEPTRA offers some advantage over the use of other antimicrobial agents. To date, there are limited data on the safety of repeated use of SEPTRA in pediatric patients under two years of age. SEPTRA 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, SEPTRA offers some advantage over the use of a single antimicrobial agent.

Travelers' Diarrhea in Adults: For the treatment of travelers' diarrhea due to susceptible strains of enterotoxigenic E. coli. 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. For prophylaxis against Pneumocystis carinii pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis carinii pneumonia.

SEPTRA NEWS HIGHLIGHTS

Published Studies Related to Septra (Trimethoprim / Sulfamethoxazole)

A randomized trial of ceftriaxone versus trimethoprim-sulfamethoxazole to prevent ventriculoperitoneal shunt infection. [2008.04]
BACKGROUND AND PURPOSE: Shunt infection represents a particularly morbid condition, which can also result in mortality. In order to decrease the high morbidity and mortality rates, prevention is an essential step. The purpose of this study was to compare the prophylactic use of ceftriaxone and trimethoprim-sulfamethoxazole (SXT) for the prevention of ventriculoperitoneal (VP) shunt infection... CONCLUSION: Ceftriaxone and SXT showed similar efficacy in preventing shunt infection. Cerebrospinal fluid leakage before or after VP shunt placement and aqueductal stenosis were independent risk factors for meningitis after VP shunt.

Simultaneous determination of sulfamethoxazole and trimethoprim in biological fluids for high-throughput analysis: comparison of HPLC with ultraviolet and tandem mass spectrometric detection. [2008.02.15]
The comparison of two methods based on online solid phase extraction-liquid chromatography with UV (SPE-LC-UV) or mass spectrometry detection (SPE-LC-MS/MS) for the simultaneous quantification of sulfamethoxazole (SMZ) and trimethoprim (TMP) is presented. The methods were validated and proved to be accurate.The method with MS detection in comparison with UV detection proved to be more rugged and was successfully applied to pharmacokinetics studies.

Prospective randomized trial of empiric therapy with trimethoprim-sulfamethoxazole or doxycycline for outpatient skin and soft tissue infections in an area of high prevalence of methicillin-resistant Staphylococcus aureus. [2007.07]
To evaluate empirical therapy with trimethoprim-sulfamethoxazole or doxycycline for outpatient skin and soft tissue infections in an area of high prevalence of methicillin-resistant Staphylococcus aureus, a randomized, prospective, open-label investigation was performed. The overall clinical failure rate was 9%, with all failures occurring in the trimethoprim-sulfamethoxazole group.

Effectiveness of trimethoprim/sulfamethoxazole for children with chronic active otitis media: a randomized, placebo-controlled trial. [2007.05]
OBJECTIVE. The goal was to determine the clinical effectiveness of prolonged outpatient treatment with trimethoprim/sulfamethoxazole [generic for Septra] for children with chronic active otitis media... The treatment effect is most pronounced with the shorter course and disappears if administration of the medication is discontinued.

Rapid and simultaneous determination of sulfamethoxazole and trimethoprim in human plasma by high-performance liquid chromatography. [2007.02.19]
A simple and reproducible high-performance liquid chromatographic method was developed for simultaneous determination of sulfamethoxazole (SMX) and trimethoprim (TMP) in human plasma. The method entailed injection of the samples after deproteination with perchloric acid and subsequent neutralizing... The method was used for a bioequivalence study.

Clinical Trials Related to Septra (Trimethoprim / Sulfamethoxazole)

DB289 Versus TMP-SMX for the Treatment of Acute Pneumocystis Jiroveci Pneumonia (PCP) [Suspended]

A Randomized, Double-Blind Study of 566C80 Versus Septra (Sulfamethoxazole/Trimethoprim) for the Treatment of Pneumocystis Carinii Pneumonia in AIDS Patients [Completed]
To evaluate the effectiveness of atovaquone (566C80) compared to a standard antipneumocystis agent, (SMX/TMP), for the treatment of mild to moderate Pneumocystis carinii pneumonia (PCP) in AIDS patients. To compare the safety of short-term (21 days) treatment with 566C80 and SMX/TMP in AIDS patients with an acute episode of PCP.

Standard therapies for acute treatment of PCP involve either SMX/TMP or pentamidine isetionate. Although both treatments are equally effective, side effects prevent completion of therapy in 11-55 percent of patients.

Impact of Cotrimoxazole Prophylaxis for HIV-Infected Adults on Antifolate Resistance [Completed]
At least three studies in sub-Saharan Africa have demonstrated a decrease in morbidity or mortality among HIV-infected adults who took daily cotrimoxazole (trimethoprim sulfamethoxazole) [CTX] prophylaxis. Because of the demonstrated beneficial effect, high tolerability and low cost of CTX, the United Nations Programme on HIV/AIDS (UNAIDS) recommends that HIV-infected persons with symptomatic HIV or depressed CD4 counts receive daily CTX. The effect of this recommendation on subsequent development of antimicrobial resistance to antifolates among important pathogens needs to be evaluated. The investigators measured the change in the prevalence of markers of antifolate resistance among P. falciparum, and the change in the prevalence of CTX resistance among S. pneumoniae, and E. coli in HIV-infected individuals receiving CTX daily prophylaxis. In addition, the investigators measured the change in the prevalence of naso-pharyngeal or oro-pharyngeal carriage of CTX resistant S. pneumoniae among children living in households where an HIV-infected adult was receiving CTX daily prophylaxis.

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.

Daily Co-Trimoxazole Prophylaxis to Prevent Malaria in Pregnancy [Recruiting]
Malaria is a major contributor of disease burden in Sub-Saharan Africa, and pregnant women and children are the most vulnerable population. Malaria in pregnancy increases the risks of abortion, prematurity, maternal anaemia, low birth weight (LBW), perinatal, neonatal and infant mortality. For prevention and control of malaria in pregnancy, Intermittent Preventive Treatment (IPT), insecticide treated nets (ITNs) and case management for malaria and anemia are recommended.

HIV infection in pregnancy increases the risk of malaria, LBW, post-natal mortality and also of anaemia. In pregnant women, HIV infection decreases the efficacy of IPT with the medicine sulfadoxine-pyrimethamine (SP), which is the only treatment with proven efficacy and safety in IPT and is recommended by the World Health Organization (WHO). Unfortunately, there is a documented increase of resistance to SP, so cotrimoxazole (CTX) could be an alternative: many studies in Zambia and Uganda demonstrated that it reduces mortality and morbidity in HIV infected persons, and CTX prophylaxis significantly improves birth outcomes in immuno-suppressed HIV women. Unfortunately, there is not yet information on its effectiveness for preventing placental malaria infection, maternal anaemia and LBW. Thus in this study, we aim to establish the safety and efficacy of daily CTX in preventing malaria infection during pregnancy and its consequences, both in HIV infected and non-infected pregnant women. This information is urgently needed to assist to issue guidelines on IPT in pregnancy.
