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. -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).

Azithromycin AZM is routinely recommended as a component of dual therapy for gonorrhea in combination with third-generation cephalosporins 3GC. In this. Many antibiotics are contraindicated in certain patient groups (e.g., children, pregnant or lactating women). In the case of severe infections, early initiation of one or more antibiotics without waiting for a microbiological confirmation is indicated (empirical antibiotic therapy), with the aim of targeting the most likely pathogen(s). Because of widespread use of antibiotics (often misuse! Update to CDC’s Sexually Transmitted Diseases Treatment Guidelines, 2010: Oral cephalosporins no longer a recommended treatment for gonococcal infections. CDC reporters del Rio and colleagues write in MMWR: 1. Update to CDC’s Sexually Transmitted Diseases Treatment Guidelines, 2010: Oral cephalosporins no longer a recommended treatment for gonococcal infections. gonorrhoeae by culture is declining rapidly because of the widespread use of NAATs for diagnosing gonorrhea. Unfortunately, the capacity of US laboratories to isolate N. All positive cultures for test-of-cure should undergo phenotypic antimicrobial susceptibility testing. If the NAAT is positive, make every effort to perform a confirmatory culture. The ideal test-of-cure is performed with culture or, if culture is not readily available, with a nucleic acid amplification testing (NAAT).
