    Is azithromycin a cephalosporin


    20%) of Gonococcal Isolate Surveillance Project (GISP) isolates with tetracycline (i.e., doxycycline) resistance and the results of two observational studies which showed inferiority of cephalosporins plus doxycycline (Barbee et al. and Sathia et al.), azithromycin is the preferred second agent to accompany ceftriaxone. All individuals treated for gonorrhea should receive two drugs, both to ensure clinical cure and to prevent the development of resistance. Persons treated with an alternative regimen for pharyngeal gonorrhea, should receive a test of cure three to four weeks after treatment. The use of dual therapy for the treatment of gonorrhea is important for two reasons: the first is to ensure clinical cure in this era of evolving antimicrobial resistance; and, the second is to prevent further development of resistance. Often in clinical practice, patients are treated with azithromycin for urethritis on one day, and screening tests return positive for gonorrhea on the next. The goal of dual therapy is to have both drugs active simultaneously. doxycycline course -proaxetil 200 mg orally, and cefuroxime-axetil 1 g orally all meet minimum efficacy criteria for alternative regimens for urogenital infections, efficacy in treating pharyngeal infections is unsatisfactory (estimated to be 70%, 79%, and 57%, respectively) and there are concerns about the pharmacodynamics of both the lower dose of and the 1 g dose of cefuroxime-axetil. Spectinomycin in a single 2 g IM dose might be useful in persons who cannot tolerate cephalosporins (estimated efficacy 98% for uncomplicated urogenital and anorectal infections), but the drug is relatively expensive, must be injected, is not effective against pharyngeal gonococcal infection (estimated efficacy 52%) or incubating syphilis, and is not available currently in the U. Azithromycin, approved for the treatment of nongonococcal infections, has been evaluated for treating gonococcal infections. Azithromycin 2 g orally is effective (estimated efficacy 99%) for uncomplicated urogenital, anorectal, and pharyngeal gonococcal infections,, ceftazidime, ceftibuten, ceftizoxime, ceftriaxone, cefdinir, cefditoren, cefepime, and cefixime. (Again, note that they all begin with “cef-.” In addition, some texts classify cefepime by itself as a fourth-generation cephalosporin.)As a group, third-generation cephalosporins have wide activity against gram-negative microorganisms. In addition, many of the drugs in this class (cefotaxime and ceftriaxone) also possess some coverage against anaerobic bacteria. Activity against gram-positive microorganisms is less reliable with third-generation cephalosporins than with previous generations. Some of these drugs are active against (ceftazidime); others cross the blood-brain barrier and can be used to treat meningitis (ceftriaxone).

    Tamoxifen is widely prescribed for women with early-stage estrogen receptor positive (ER ), HER2-negative breast cancer following surgery. A 5- to 10-year course delays local and distant recurrence, prolongs overall survival, and reduces the incidence of contralateral breast cancer. Therapeutic drug monitoring based on tamoxifen metabolite concentrations accounts for the factors that impact tamoxifen effectiveness, including interindividual variation caused by CYP2D6 polymorphisms, liver disease, drugs, and patient adherence. It is a direct measure of the amount of active drug in the individual patient. Jager et al reported that increasing the tamoxifen dosage increases the amount of active drug in patient plasma. Clinical cutoffs for tamoxifen and its metabolites are not yet fully established. Data from Madlensky et al show a marginally significant reduced risk of breast cancer recurrence in patients with an endoxifen concentration in the upper 4 quintiles relative to the lowest quintile (HR=0.74; 95% CI, 0.55-1.00).
