Also, amitriptyline, clomipramine and desipramine levels may be t by propafenone. Amitriptyline and clomipramine may t propafenone levels.

Protein synthesis. Drugs that interfere at various points with the build-up of peptide chains on the ribosomes of the organism include chloramphenicol, erythromycin, fusidic acid, tetracyclines, aminoglycosides, quinupristin/dalfopristin, linezolid. 

After 5 days administration of quinupristin + dalfopristin 7.5 mg/kg infused over 1 hour bd, the fecal microflora in 20 healthy volunteers increased significantly during treatment and returned within 12 weeks to baseUne concentrations after the end of treatment. There were anerobes and enterococci resistant to erythromycin or to quinupristin - - dalfopristin, but glycopeptide-resistant enterococci did not emerge (22).
