Niosomes from Preparation to Application in Drug Delivery

Niosomes – Vesicular Drug Delivery System

At present days drugs are formulated by using different novel drug delivery system (NDDS) which are used for targeting drugs to different organ systems and for controlled /sustained release of drug from the dosage forms. The NDDS can be used to overcome many disadvantages of conventional dosage forms like poor bioavailability, first pass effect, systemic toxicity, degradation of drug in stomach...

Niosomes as Carrier in Dermal Drug Delivery

Niosomes : a Novel Trend in Drug Delivery

Niosomes are a novel drug delivery system, in which the medication is encapsulated in a vesicle. Niosomes are formations of vesicles by hydrating mixture of cholesterol and nonionic surfactants. Different novel approaches used for delivering these drugs include liposomes,microspheres, nanotechnology, micro emulsions, antibody loaded drug delivery, magnetic microcapsules, implantable pumps and n...

Niosomes: an Excellent Tool for Drug Delivery

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 ves...

Niosomes: A Novel Drug Delivery System

Paul Ehrlich, in 1909, initiated the development for targeted delivery when he envisaged a drug delivery mechanism that would target directly to diseased cell. Drug targeting can be defined as the ability to direct a therapeutic agent specifically to desired site of action with little or no interaction with non target tissue 1 . In noisome, the vesicles forming amphiphile is a non-ionic surfact...

Niosomes: a Role in Targeted Drug Delivery System

Niosomes are non-ionic surfactant vesicles inclosing an aqueous phase and a wide range of molecules could be encapsulated within aqueous spaces of lipid membrane vesicles. They are microscopic lamellar structures formed on the admixture of a non-ionic surfactant, cholesterol and phosphate with subsequent hydration in aqueous media. Niosomes belongs to novel drug delivery system which offers a l...
