Propolis Outperforms Periodontal Medication

A well-known fact, Propolis is very effective when used to treat conditions in the mucous linings of the body. From the mouth, nose, throat, lungs, intestinal tract and the organs therein, propolis exhibits a protective effect that is consistent, no matter the origin of the Propolis. So, start out with a good propolis toothpaste and continue consuming propolis daily...


Microparticles Containing Propolis and Metronidazole: in vitro Characterization, Release Study and Antimicrobial Activity Against Periodontal Pathogens
Pharm DevTechnol, 2013 Jan 28

Abstract:
Ethylcellulose microparticles containing metronidazole and propolis extractive solution were prepared and evaluated in vitro against periodontal pathogens.
Scanning electron microscopy, particle size analysis, drug entrapment efficiency and drug release of microparticles were determined. The antimicrobial activity of microparticles was evaluated against microorganisms of periodontal importance (Enterococcus faecalis, Streptococcus pyogenes, Streptococcus mutans, Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli). It was obtained particles with regular morphology, mean diameter of 1.23 µm, and entrapment efficiency for propolis and metronidazole were 91.41% and 22.23%, respectively. In vitro release studies of propolis and metronidazole from microparticles showed prolonged drug release and controlled by Fickian diffusion.
Both propolis and metronidazole displayed activity against the tested strains. Moreover, the results showed that the strains of E. faecalis, S. pyogenes and S. mutans were more susceptible to the propolis and E. faecalis to the metronidazole. It was also observed that the amount of metronidazole to inhibit the microorganism strains in the physical mixture with propolis was smaller than in the metronidazole alone, suggesting potentiation effect between propolis and metronidazole.
These microparticles would be useful for developing intermediary or eventual dosage form to be administered into the periodontal pocket more easily and safely.
