Actinospectacin - General Information

An antibiotic produced by Streptomyces spectabilis. It is active against gram-negative bacteria and used for the treatment of gonorrhea.


Pharmacology of Actinospectacin

Actinospectacin 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.


Actinospectacin for patients

Patients should be counseled that antibacterial drugs including TROBICIN Sterile Powder should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When TROBICIN Sterile Powder is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by TROBICIN Sterile Powder or other antibacterial drugs in the future.
