Abstract

Resumen: En el presente trabajo se valora la eficacia antibacteriana del colutorio Tantum verde® y la de su, presuntamente, único principio activo, la bencidamina clorhidrato. Para ello, se ensayó la actividad in vitro de la bencidamina HCl y del Tantum verde mediante la obtención de las correspondientes CMI (Concentración Mínima Inhibitoria) siguiendo la técnica de la dilución en medio sólido. Inicialmente, se estudiaron ocho cepas de uso común en el laboratorio y, posteriormente, el estudio fue ampliado a cepas de patóge-nos bucales aisladas de muestras clínicas. Los estudios realizados, demuestran una efica-cia bactericida real frente a patógenos bucales pertenecientes a géneros tales como Acti-nomyces, Bacillus, Actinobacillus, Veillonella o Streptococcus. Además, el Tantum verde como colutorio posee, en general, una mayor actividad antibacteriana que la demostra-da por su principal principio activo, la bencidamina HCl, por lo que cabe pensar que la pre-sencia de etanol a baja concentración, en su composición contribuye de forma notable a la acción antibacteriana. Abstract: This work is devoted to the evaluation of the antibacterial activity of Tantum verde® mouth-rinsing solution and its supposedly only active principle, benzidamine HCl. For this reason, the activity in vitro of Tantum verde and benzidamine HCI was tested by measuring MIC (Minimal Inhibitory Concentration) by means of serial dilutions on solid medium. Eight bacterial species commonly used and a set of oral pathogenic microorganisms isolated from clinical samples in the laboratory were studied. Results showed an actual bactericidal effect on oral pathogens such as Actinomyces, Bacillus, Actinobacillus, Veillonella o Streptococcus. Moreover, Tantum verde as a mouth rinsing solution had a higher antibacterial activity than its active principle (benzidamine HCl). This suggests that the presence of low concentrations of ethanol present in the composition of Tantum verde contributes remarkably to the antibacterial action.
