Liposome—A Novel Drug Delivery System

Novel transdermal drug delivery systems

Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...

Microemulsions: A potential novel drug delivery system

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...

Novel Aproaches - Mucoadhesive Buccal Drug Delivery System

Among novel drug delivery systems, Buccal mucoadhesive systems have attracted great attention in recent years due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. Mucoadhesion may be defined as the process where polymers attach to biological substrate or a synthetic or natural macromolecule, to mucus or an epithelial surface. Buccal mucoadhes...

A Novel Approch : Pulsatile Drug Delivery System

Pulsatile drug delivery system (PDDS) is useful in the treatment of disease, in which drug availability is timed to match rhythms of disease, in order to optimize therapeutic effect and minimize side effects. PDDS have attracted attraction because of their multiple benefits over conventional dosage forms. The specific time that patients take their medication is very important as it has signific...
