For most situations, generally start with broader antibiotics until pathogen and susceptibilities identified. Good choice for cellulitis, osteomyelitis, endocarditis, and bacteremia from MSSA. Anti-pseudomonal PCNs - Piperacillin, Ticarcillin Usually combined with beta lactamase inhibitors see below which confers broader activity; however, beta-lactamase component does not add activity vs Pseudomonas so if Pseudomonas is sensitive, could use Piperacillin alone. Spectrum: similar to Unasyn in having gram positive, gram negative, anaerobic coverage, but better overall gram negative coverage, including Pseudomonas and most SPICE A organisms. Cefazolin ofted used for prophlaxis during surgery.

During the past 3 decades, the combination of trimethoprim and sulfamethoxazole has occupied a central role in the treatment of various commonly encountered infections and has also been particularly useful for several specific clinical conditions. However, changing resistance patterns and the introduction of newer broad-spectrum antibiotics have led to the need to carefully redefine the appropriate use of this agent in clinical practice. It also seems to have an increasing role as a cost-effective pathogen-directed therapy with the potential to decrease or delay development of resistance to newer antibiotics used for empirical treatment. In addition, trimethoprim-sulfamethoxazole continues to be the drug of choice for several clinical indications. Many new antibiotics offer an expanded spectrum of in vitro antimicrobial susceptibility and an improved toxicity profile compared with older agents. With a renewed interest in appropriate antibiotic use for common infections 1 and the current focus on providing cost-conscious health care, this article examines the combination of trimethoprim and sulfamethoxazole to redefine its therapeutic role in relation to newer antimicrobial agents in the face of resistance trends and adverse effect profiles. The concept of using the fixed combination of trimethoprim and sulfamethoxazole resulted from the recognition that bacteria are obligate folic acid synthesizers, while humans obtain folate through dietary sources.

Given the potential risk of diabetic foot ulcers becoming infected, it is imperative to have a strong understanding of the current antibiotic options. Diabetic foot infections DFIs are a common and often severe problem for people with diabetes. Those wounds that are not infected do not require the initiation of antibiotic therapy. However, for those wounds that are infected, the need for antibiotic treatment is paramount. Vancomycin is known to be associated with a risk of nephrotoxicity, especially when one combines it with other nephrotoxic antibiotics such as an aminoglycoside.

Most uncomplicated urinary tract infections occur in women who are sexually active, with far fewer cases occurring in older women, those who are pregnant, and in men. Although the incidence of urinary tract infection has not changed substantially over the last 10 years, the diagnostic criteria, bacterial resistance patterns, and recommended treatment have changed. Trimethoprim-sulfamethoxazole has been the standard therapy for urinary tract infection; however, E. Uncomplicated urinary tract infections UTIs are one of the most common diagnoses in the United States. Algorithm for the management of uncomplicated urinary tract infections.

Clinical manifestations and diagnosis of cellulitis and erysipelas are discussed separately. See Cellulitis and skin abscess: Epidemiology, microbiology, clinical manifestations, and diagnosis. Treatment of skin abscess is discussed elsewhere. See Skin abscesses in adults: Treatment. Beta-hemolytic streptococci cause the vast majority cheap lamisil 250mg erysipelas infections and most cellulitis infections, but cellulitis is sometimes caused by Staphylococcus aureus and occasionally by a multitude of other organisms.

All medicines have risks and benefits. There are many different types of medicines used to treat bacterial infections. Trimethoprim belongs to a group of medicines known as the benzylpyrimidines. Another infection later on may require a different medicine. You may need to use different amounts of your medicine, or you may need to take different medicines.

Co-trimoxazole is used to treat certain bacterial infections, such as pneumonia a lung infection, bronchitis infection of the tubes leading to the lungs, and infections of the urinary tract, ears, and intestines. It also is used to treat 'travelers' diarrhea. It works by stopping the growth of bacteria. Antibiotics will not kill viruses that can cause colds, flu, or other viral infections. Co-trimoxazole comes as a tablet and a suspension liquid to take by mouth. It usually is taken two times a day but may be taken up to four times a day when used to treat certain severe lung infections.

The metabolism of sulfamethoxazole occurs predominately by N4-acetylation, although the glucuronide conjugate has been identified. The principal metabolites of trimethoprim are the 1- and 3-oxides and the 3'- and 4'-hydroxy derivatives. Excretion of sulfamethoxazole and trimethoprim is primarily by the kidneys through both glomerular filtration and tubular secretion. Urine concentrations of both sulfamethoxazole and trimethoprim are considerably higher than are the concentrations in the blood. When administered together, neither sulfamethoxazole nor trimethoprim affects the urinary excretion pattern of the other. Both sulfamethoxazole and trimethoprim distribute to sputum and vaginal fluid; trimethoprim also distributes to bronchial secretions, and both pass the placental barrier and are excreted in breast milk.
