Setting Starting Level for a Trial of a Biofilm-Disrupting Adjuvant

Combination therapy is beneficial treatment modality for multiple diseases. Cinnamon oil may be an advantageous agent in a number of combination therapies as cinnamon oil has antibacterial activity. Cinnamon oil has also been shown to be effective against biofilm cultures of Streptococcus mutans and Lactobacillus plantarum. Cinnamomum osmophloeum inhibits planktonic cultures of many gram-positive and gram-negative bacteria, including MRSA (methicillin-resistant Staphylococcus aureus). Subjecting S. epidermidis to cinnamon oil eliminates planktonic cells or staphylococci in biofilms. Cinnamon oil is an essential oil used throughout the food industry because of its pleasant and distinctive aroma. The purpose of this study is to estimate the amount of exposure to cinnamon through selected foods in the United States in order to propose an initial target level for pharmacokinetic studies of a novel combination drug.
