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.

Show all documents The Itraconazole nanoemulsion formulations were prepared by solvent displacement method using Capryol 90 as lipid phase was dissolved in water miscible organic solvent methanol. The organic phase oil and Itraconazole drug was mixed into an aqueous phase containing poloxamer , tween 80 and distilled water to produce nanoemulsion by quick dispersion of organic solvent. Organic solvent was separated from nanoemulsion by vacuum evaporation. Direct compression one of the techniques requires the incorporation of a super disintegrants into the formulation the use or highly water soluble excipients to achieve fast tablet disintegration.

Formulation and Evaluation of Nanoemulsion Gel of Tenoxicam For Topical Application

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. The nanoemulsion area was identified by constructing ternary phase diagrams. The prepared nanoemulsions were subjected to different thermodynamic stability tests to screen out the stable formulations among various prepared formulation having different smix ratios with oil phase.

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.

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 have attracted much attentions due to the transparent or translucence appearance, physical stability, high bioavailability and non-irritant in nature. In general, nanoemulsions with small droplet size can enhance the bioavailability of drugs, whereas this phenomenon is likely system dependent. In present study, NCTD nanoemulsions were developed and optimized to evaluate and improve the insecticidal activity of NCTD against Plutella xylostella Lepidotera: Plutellidae by a spontaneous emulsification method.

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.

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. Due to the treatment of fungal infection with topical drug preparation taking a long time for treatment, the development of delivery systems may increase the effectives of treatment. This research aimed to develop ketoconazole nano-emulsion topical preparation and to study the antifungal efficacy of the developed formulation. The nano-emulsion bases were prepared using the low-energy emulsification method. A formula with a nanoscale of internal droplets was selected based on stability at 30 o C and 45oC for thirty days.

Халохот пролетел пять полных витков спирали и замер. До Апельсинового сада оставалось всего двенадцать ступенек. ГЛАВА 101 Дэвид Беккер никогда не держал в руках оружия. Сейчас ему пришлось это сделать. Скрюченное тело Халохота темнело на тускло освещенной лестнице Гиральды. Беккер прижал дуло к виску убийцы и осторожно наклонился. Одно движение, и он выстрелит.

 - Вы что-то нашли. - Вроде.  - У Соши был голос провинившегося ребенка.  - Помните, я сказала, что на Нагасаки сбросили плутониевую бомбу.

 Но… офицер ничего не сказал о… - Разумеется. Я не сказал ему про спутницу.  - Взмахом руки Клушар величественно отверг вопрос Беккера.  - Они не преступницы - глупо было бы искать их, как обычных жуликов. Беккер все еще не мог прийти в себя от всего, что услышал. - Может, там был кто-нибудь .

Пришла пора действовать. Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала. Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод. - Сьюзан! - рявкнул голос у нее за спиной.
