NaturalOilsEnhancetheTopicalDeliveryofKetoconazoleby Nanoemulgel forFungal Infections

Nano emulgel(NEG)pharmaceutical formulations are gaining popularity because of the irability to serve both as a nano emul sionandasa gel.These products are well-known for their easeofuse, spread ability, control ledre lease, and ability to hydrate dry skin. Natural essential oils have been shown to promote the cutaneous permeability of topical formulations, enhancing medication safety and efficacy. Herein, we developed NEG for the enhanced permeation of ketoconazole against candidiasis using clove oil (clove-oil−NEG) or eucalyptus oil (eucalyptus-oil−NEG), using the gelling agents carbopol943 and hydroxy propyl methyl cellulose(HPMC).Wetested various excipients to increase the solubility of ketoconazole and formulate a nano emulsion (NE).We measured the NE droplet particle size ,shape ,
entrapment efficiency,and drug release. Furthermore, the physico chemical properties of the optimized nano emulsion formulation were characterized by techniques such as Fourier transform infrared (FT-IR) spectroscopy and Xray diffraction (XRD) analysis.The NEs were loaded into gel stoform NEGs. NEGs were characterized for drug content, homo geneity ,rheology ,spread ability, and anti fungal activity against Candida albicans, both invitro and in vivo. Optimized ketoconazole NEG preparations consisted of either 15% clove oil or 20% eucalyptus oil. Droplet sizes in the optimized NEs were <100 nm, and the polydispersity indexes were 0.24 and 0.26. The percentages of ketoconazole released after 24 h from the clove-oil-NEGandeucalyptus-oil−NEGswere91±4.5and89±7%, respectively. Scanning electron microscopy(SEM) showed that the NEGs had a smooth ,uniform, and consistent shape and internal structural organization.The drug contents in the clove-oil−NEG and eucalyptus-oil−NEG were 98.5 ±2.2 and 98.8 ±3.4%, respectively.Permeation values of ketoconazole from clove-oil−NEG and eucalyptus-oil−NEG were 117 ±7 and 108.34 ±6μgcm−2, respectively. The ketoconazole NEG formulations also had higher levels of fungal growth inhibition than a marketed formulation. Finally, in vivo studies showed that the NEGs do not irritate the skin. Ketoconazole NEG with either 15% clove oil or 20% eucalyptus oil is stable with better efficacy thank to cenazole alone due to excellent dispersion, drug dissolution, and permeability and thus might be recommended for the effective and safe treatment of candidiasis.
