Niosomes as vesicular carriers for delivery of proteins and biologicals (original) (raw)

Nano-niosomes in drug, vaccine and gene delivery: a rapid overview

Niosomes, non-ionic surfactant vesicles (NSVs), are the hydrated lipids composed mainly of different classes of non-ionic surfactants, introduced in the seventies as a cosmetic vehicle. Nowadays, niosomes are used as important new drug delivery systems by many research groups and also they are effective immunoadjuvants which some commercial forms are available in the market. These vesicles recently used as gene transfer vectors as well. This review article presents a brief report about the achievements in the field of nanoscience related to NSVs. Different polar head groups from a vast list of various surfactants with one, two or three lipophilic alkyl, perfluoroalkyl and steroidal moieties may be utilized to form the proper vesicular structures for encapsulating both hydrophilic and hydrophobic compounds. The methods of niosome preparation, the vesicle stability related aspects and many examples of pharmaceutical applications of NSVs will be presented. The routes of administration of these amphiphilic assemblies are also discussed.

Niosomes: A Novel Drug Delivery System

Niosome are non-ionic surfactant vesicles obtained on hydration of synthetic nonionic surfactants, with or without incorporation of cholesterol or their lipids. They are vesicular systems similar to liposomes that can be used as carriers of amphiphilic and lipophilic drugs. Noisome are promising vehicle for drug delivery and being non-ionic; and Niosomes are biodegradable, biocompatible nonimmunogenic and exhibit flexibility in their structural characterization. Niosomes have been widely evaluated for controlled release and targeted delivery for the treatment of cancer, viral infections and other microbial diseases. Niosomes can entrap both hydrophilic and lipophilic drugs and can prolong the circulation of the entrapped drug in body. Encapsulation of drug in vesicular system can be predicted to prolong the existence of drug in the systemic circulation and enhance penetration into target tissue, perhaps reduce toxicity if selective uptake can be achieved. This review article focuses on the advantages, Disadvantages, preparation methods, factors affecting, characterizations, invitro methods, drug release kinetics, and applications of noisome.

Niosomes as a Potential Drug Delivery System

International Journal of Pharmaceutical Sciences Review and Research, 2021

A non-ionic vesicle dependent on surfactants is a niosome. Niosomes are mainly formed as an excipient by non-ionic surfactant and cholesterol incorporation. Various excipients can also be used. Niosomes have a greater penetrating potential than previous emulsion preparations. There are various methods of manufacturing niosomes like thin film hydration, microfluidization, sonication, bubble method to name a few. The fact that niosomes are amphiphillic molecules makes them a flexible carrier of drugs, as both hydrophilic and lipophillic drugs can be trapped. Applications of niosomes in the pharmaceutical industry are many, some of the most important ones being as cosmoceuticals, gene delivery carriers, carriers for vaccine delivery and also in medical imaging. The main object of this review the appliance of niosome technology is employed to treat variety of diseases, niosome have good opportunity in research and beneficial for researcher and pharma industries. As niosome is stable and...

Niosomes : as novel vesicular drug delivery system

2018

Target-specific drug-delivery systems for the administration of pharmaceutical compounds enable the localization of drugs to target sites within the body. The basic component of drug delivery systems is an appropriate carrier that protects the drug from rapid degradation or clearance and thereby enhances drug concentration in target tissues. Niosome are microscopic non-ionic surfactant bilayer vesicles obtained on hydration of synthetic nonionic surfactants, with or without incorporation of cholesterol or their lipids. The amphiphilic nature of niosomes promotes their efficiency in encapsulating lipophilic or hydrophilic drugs. Noisome are promising vehicle for drug delivery and being non-ionic, more stable, inexpensive, biodegradable, biocompatible, non immunogenic and exhibit flexibility in their structural characterization. Various additives in niosomes include nonionic surfactant as film forming agent, cholesterol as stabilizing and rigidizing agent for the bilayer and various c...

Formulation and evaluation of niosomes

Indian journal of pharmaceutical sciences, 2011

Span 20-based niosome was prepared by lipid film hydration technique and loaded with Newcastle disease vaccine. Three batches with Span 20, cholesterol and dicetyl phosphate in micro molar ratios of 10:10:1; 15:15:1 and 20:20:1 were prepared and evaluated for encapsulation efficiency using haemagglutination test. The morphology of the vesicles was studied by means of transmission electron microscopy. Particle size, zeta potential and polydispersity index were determined by photon correlation spectroscopy using a nanosizer. Adjuvanticity was assessed using haemagglutination inhibition test. The vesicles of Span 20-based niosomes were distinct, near spherical large unilamellar vesicles. The vesicles were of varied sizes (<1000 nm) with the entrapped Newcastle disease vaccine in the core of the vaccine. The zeta potential had a peak at -50 mV. The polydispersity index was 0.68. Haemagglutination inhibition test showed a 71% increment in immune response over that of the marketed La S...

Niosomes: A Controlled and Novel Drug Delivery System

Biological & Pharmaceutical Bulletin, 2011

During the past decade formulation of vesicles as a tool to improve drug delivery, has created a lot of interest amongst the scientist working in the area of drug delivery systems. Vesicular system such as liposomes, niosomes, transferosomes, pharmacosomes and ethosomes provide an alternative to improve the drug delivery. Niosomes play an important role owing to their nonionic properties, in such drug delivery system. Design and development of novel drug delivery system (NDDS) has two prerequisites. First, it should deliver the drug in accordance with a predetermined rate and second it should release therapeutically effective amount of drug at the site of action. Conventional dosage forms are unable to meet these requisites. Niosomes are essentially non-ionic surfactant based multilamellar or unilamellar vesicles in which an aqueous solution of solute is entirely enclosed by a membrane resulting from the organization of surfactant macromolecules as bilayer. Niosomes are formed on hydration of non-ionic surfactant film which eventually hydrates imbibing or encapsulating the hydrating aqueous solution. The main aim of development of niosomes is to control the release of drug in a sustained way, modification of distribution profile of drug and for targeting the drug to the specific body site. This paper deals with composition, characterization/evaluation, merits, demerits and applications of niosomes.
