Niosome thesis

Both UV and light scattering optical microscope provide a magnification range from plus eye piece magnification. The aqueous phase 0. The stability of the final structure depends on the type of emulsion which is created oil in water or water in oil.

Dissertation On Niosomes

Possible formation of liposome vesicles when hydrating in aqueous solution www. Elongation and several vesicles were observed With the interior volume previously calculated based on the result of PSS, the final concentration can be calculated.

In this work, a potential drug delivery sy stem has been designed, synthesized and characterized. Standard curve of floresce nce intensity vs. The gel matrix consists of spherical beads with pores of a specific size distribution.

Itraconazole is a drug of choice for patients with indolent, nonmeningeal infections due to B. Fresh distilled water was used for all the formulation.

This included pa rameters such as mass per batch, angle of evaporation, dehydration nitrogen flowrate hydrating solvents, hydrating temperature and sonication time. Mainly two types of vesicle skin interactions occurs during in vitro studies using human skin which may induce various effects on dermal or transdermal drug delivery [ 10 — 12 ].

PAGE 54 41 Table The standard sample volume of H 2 0 inside this vessel was set to 35 ml. By virtue of penetration of individual phospholipid molecules or nonionic ether surfactants into the lipid layers of the stratum corneum and epidermis, they may serve as penetration enhancer and facilitate dermal delivery leading to higher localized drug concentrations.

Formulated niosomes were evaluated for vesicle size, entrapment efficiency, drug release, skin permeation, and antimycotic activity.

Chemical structure of 5 6 -carboxyfluorescein Premade CF solutions, in the range of 5 mM, exhibit self-quenching higher concentration of CF molecules with a bright fluorescein color decrease the intensity reading of the fluorescent from fluorometer and can be entrapped inside niosomes, exhibiting low intensity fluorescence.

Itraconazole niosome were having larger zone of inhibition than marketed formulation when activity was checked against C. PAGE 44 31 4.

Approximately half of the patients with distal subungual onychomycosis respond well to Itraconazole. Higher concentration solutions exhibit higher probabilities of false readings because more than one particle might pass between the photodiode array detector and the light scattering emitter.

Chemical structure of Phosphatidyl-choline PC. Niosome preferredwas prepared using Span 60, Tween 20 nonionic surfactants- and cholesterol with heating and sonication method, which is simple, fast and inexpensive. The niosome entrapped drug was separated from the free drug by the centrifugation method.

The prepared niosomal dispersion was subjected for centrifugation at high rpm for 30 min. Clear supernatant liquid was separated from niosomes. Jul 16,  · Zidovudine (AZT) is commonly used to treat patients with AIDS, but it is limited by toxicity and high dosing needs.

Alternative formulations have been proposed to overcome these drawbacks. Niosome 1. By Dr. Shreeraj Shah Associate Professor,Dept. of Pharmaceutical Technology, L.J. Institute of Pharmacy, Ahmedabad 1 2. Content Introduction General characteristics of Niosomes Advantage of Niosomes Disadvantage of Niosomes Structure of Niosomes Contrast and similarity between Niosomes and Liposomes Methods of Preparation Factors.

during niosome preparation may affect these parameters and hence the performance of the formulation. Factorial design and response surface methodology is an important statistical tool to study the effect of several factors influencing responses by varying them simultaneously by.

Niosomes and Liposomes - Vesicular Approach Towards Transdermal Drug Delivery Thakur Varun*, Arora Sonia, Prashar Bharat and Vishal Patil Manav Bharti University, VillageLaddo, P.O.-Sultanpur(Kumharhatti), Tehsil & Distt. Solan.
