This paper emphasizes the formation of a positively charged nanoemulsion system for steroid drugs hydrocortisone. It is believed that positively charged nanoemulsion provides more effective penetration of the skin. Therefore in our study we focused on the incorporation of phytosphingosine which serves as a positively charged cosurfactant in the nanoemulsion system. Negatively charged nanoemulsions were formulated mainly for comparison. The oil-in-water nanoemulsion also showed good viscosity, conductivity, and pH values. From TEM micrograph, particle size showed consistent results with the measurement using photon correlation spectroscopy. It was concluded that both positively and negatively charged nanoemulsions showed good stability and have great potential in transdermal delivery system.
Sunscreen product that contains active chemical ingredients sometimes has harmful effects on the skin. Sunflower oil contains vitamin E and acts as a natural sunscreen which can absorb UVB light. The average droplet size of nanoemulsion is between and nm and do not show the problems of stability creaming, flocculation, coalescence, and sedimentation , which are commonly associated with macroemulsions. The aim of this study was to prepare and evaluate the sunflower oil nanoemulsion as a sunscreen. The results of nanoemulsion evaluation showed that nanoemulsion formula F1 had the smallest average particle size of The SPF value of all nanoemulsion preparations was higher than that of the emulsion. The preparation of t he sunflower oil nanoemulsion with a ratio of Tween 80 and sorbitol 22 produces a stable nanoemulsion during the experiment for 12 weeks storage at the room, low and high temperature.
The present study aimed to design, optimize , and evaluate primaquine loaded nanoemulgel for malaria treatment. Nanoemulgel was prepared with the help of different components such as castor oil, Tween Transcutol P S mix ratio , and polymers. Pseudoternary phase diagram was constructed to optimize S mix ratio. Based on these parameter results, F5 formulation was selected as an optimized formulation. The prepared nanoemulgel was evaluated with the following parameters: percent drug content, in vitro drug release, ex vivo skin permeation, pH determination, spreadability determination, and viscosity measurement. Response surface curves were plotted for optimization of perfect nanoemulsion preparation. The nanoemulsion loaded hydrogel of primaquine with optimum viscosity was prepared for transdermal application.
Metrics details. Norcantharidin NCTD , a demethylated derivative of cantharidin defensive toxin of blister beetles , has been reported to exhibit insecticidal activity against various types of agricultural pests. However, NCTD applications are limited by its poor water solubility and high dosage requirement.
Nanoemulsions are clear, thermodynamically stable mixtures of oil, water, surfactant and co-surfactant. These are the oil-in-water type of emulsions with the average droplet size ranging from 5 nm to nm.
TThe treatment of fungal skin infections using antifungal drug topical preparations often takes a long time for treatment. The advantages of using topical medication Is to reduce the risk of side effects from medication Including reducing the chance of interacting with other drugs. But when having a chronic or widespread fungal disease on the skin area, the patient must use oral medicatiopical medication.
The aim of the present study to develop a nanoemulsion gel formulation of poorly water soluble drug tenoxicam for the transdermal delivery. Nanoemulsions have the particle size range in nano range. To develop the nanoemulsion here ethyl oleate, tween and propylene glycol were selected among various types of oils, surfactants and co-surfactants for preparing nanoemulsion. Various oil-in-water nanoemulsions were prepared by the spontaneous emulsification method.
Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду.
Рядом с собором на сто двадцать метров вверх, прямо в занимающуюся зарю, поднималась башня Гиральда. Это и был Санта-Крус, квартал, в котором находится второй по величине собор в мире, а также живут самые старинные и благочестивые католические семьи Севильи. Беккер пересек мощенную камнем площадь. Единственный выстрел, к счастью, прозвучал слишком поздно. Беккер на своем мотоцикле скрылся в узком проходе Каллита-де-ля-Вирген.
