NEs are delivery systems that enhance the solubility of lipid therapeutics and improve their delivery to target sites; they are known as self-nanoemulsifying drug delivery systems (SNEDDSs). The current investigation’s aim was to produce an oregano essential oil-based nanoemulsion (OEO-SNEDD) that would have antibacterial and antifungal effects against oral microbiota and improve oral health.Methods: Several OEO-SNEDDSs were developed using different percentages of OEO (10%, 14%, and 18%), percentages of a surfactant mixture Pluracare L64:Lauroglycol FCC (18%, 32%, and 36%), Smix ratios (1:2, 1:1, and 2:1), and hydrophilic-lipophilic balances (HLBs) of the surfactant mixture (8, 10, and 12) using the Box‒Behnken design. The optimized concentration of excipients was determined using a pseudoternary phase diagram to obtain the NEs. The formulations were evaluated for their droplet size, stability index, and antibacterial and antifungal activities.Results: The NEs had a droplet size of 150 to 500 nm and stability index of 47% to 95%, and the produced formulation reached antibacterial and antifungal inhibition zones of up to 19 and 17 mm, respectively. The Box‒Behnken design was adopted to get the optimum formulation, which was 18% OEO, 36% Smix, 10.29 HLB of Smix, and a 1.25:1 Smix ratio. The optimized formulation had a lower ulcer index compared with various other formulations evaluated in rats.Conclusion: This study illustrated that OEO-SNEDDSs can provide good protection against oral microbial infections.Keywords: oregano essential oil, nanoemulsion, Box‒Behnken design, ulcer index, required HLB, carvacrol, thymol, stability indexHosny KAsfour HRizg WAlhakamy NASindi AAlkhalidi HAbualsunun WBakhaidar RAlmehmady AMAkeel SAli SAlghaith AAlshehri SKhallaf RDove Medical Pressarticleoregano essential oilnanoemulsionbox‒behnken designulcer indexrequired hlbcarvacrolthymolstability indexMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 5465-5478 (2021) |
