药理
Indication | For use in the treatment of acute gonorrheal urethritis and proctitis in the male and acute gonorrheal cervicitis and proctitis in the female when due to susceptible strains of Neisseria gonorrhoeae. | ||||||
Pharmacodynamics | Spectinomycin is an aminocyclitol antibiotic produced by a species of soil microorganism designated as Streptomyces spectabilis. In vitro studies have shown spectinomycin to be active against most strains of Neisseria gonorrhoeae (minimum inhibitory concentration <7.5 to 20 mcg/mL). Footprint studies indicate that spectinomycin exerts regional effects on ribosomal structure. | ||||||
Mechanism of action | Spectinomycin is an inhibitor of protein synthesis in the bacterial cell; the site of action is the 30S ribosomal subunit. It is bactericidal in its action. | ||||||
Absorption | Rapidly and almost completely absorbed after intramuscular injection. | ||||||
