Аннотация
AIM: The work reports a novel nanophytosomal gel encapsulating Alpinia galanga (L.) Willd leaf essential oil to treat periodontal infections.
METHODS: Alpinia oil-loaded nanophytosomes (ANPs) were formulated by lipid layer hydration technique and were evaluated by FESEM, cryo-TEM, loading efficiency, zeta potential, particle size, release profile etc. Selected ANPs-loaded gel (ANPsG) was evaluated by both in vitro and in vivo methods.
RESULTS: Selected ANPs were spherical, unilamellar, 49.32 ± 2.1 nm size, 0.45 PDI, -46.7 ± 0.8 mV zeta potential, 9.8 ± 0.5% (w/w) loading, 86.4 ± 3.02% (w/w) loading efficiency with sustained release profile. ANPsG showed good spreadability (6.8 ± 0.3 gm.cm/sec), extrudability (79.33 ± 1.5%), viscosity (36522 ± 0.82 cps), mucoadhesive strength (44.56 ± 3.5 gf) with sustained ex vivo release tendency. Satisfied ZOI and MIC was observed for ANPsG against periodontal bacteria vs. standard/control. ANPsG efficiently treated infection in ligature induced periodontitis model. Key pharmacokinetic parameters like AUC, MRT, Vd were enhanced for ANPsG.
CONCLUSION: ANPsG may be investigated for futuristic clinical studies.
