ABSTRACT
Use of antimicrobials for the treatment of gonorrhea started in 1930 with the utilization of sulfonamides. With the years other drugs were used for its treatment such as penicillin, tetracycline, spectinomycin, and others. Although highly specific in the beginning, these drugs, with time did not show anymore the expected therapeutic results because of aspects of chromosomal and plasmid-mediated resistance. The purpose of this study was to evaluate the susceptibility of Neisseria gonorrhoeae strains to six drugs used for its treatment (penicillin, tetracycline, cefoxitin, thiamphenicol, spectinomycin and ofloxacin) by the determination of minimal inhibitory concentrations of these drugs. We concluded that drugs, such as cefoxitin, thiamphenicol and spectinomycin still are excellent pharmacological agents for the treatment of gonorrhea. Penicillin, although still efficient, needs more attention regarding its use, as well as ofloxacin, because of the emergence of resistant strains. Tetracycline and its derivatives should be strongly contraindicated for the treatment of gonorrhea.
RESUMO
A utilização de antimicrobianos no tratamento da gonorréia iniciou-se em 1930 com a utilização das sulfonamidas. No decorrer dos anos outras drogas passaram a ser utilizadas em seu tratamento como a penicilina, tetraciclina, espectinomicina e outras. Embora altamente eficazes no início, essas drogas, ao longo do tempo, passaram a não mais apresentar o resultado terapêutico esperado em virtude do aparecimento de quadros de resistência cromossômica e plasmidial. Este trabalho teve por objetivo avaliar a sensibilidade de cepas de Neisseria gonorrhoeae a seis drogas utilizadas no seu tratamento (penicilina, tetraciclina, cefoxitina, tianfenicol, espectinomicina e ofloxacina) através da concentração inibitória mínima. Concluimos que drogas como a cefoxitina, o tianfenicol e a espectinomicina ainda constituem excelentes fármacos para o tratamento da gonorréia. A penicilina, embora ainda eficaz, enseja maiores cuidados na sua utilização, assim como a ofloxacina, frente ao surgimento de cepas resistentes e, a tetraciclina e seus derivados deve ser sobremaneira contra-indicada no tratamento da gonorréia.
