Nanosuspension: A Novel Drug Delivery System

Preparation and evaluation of vitamin A nanosuspension as a novel ocular drug delivery

Objective(s):  The aim of this study was to prepare a nanosuspension formulation as a new vehicle for the improvement of the ocular delivery of vitamin A.  Material and Methods:   Formulations were designed based on full factorial design. A high pressure homogenization technique was used to produce nanosuspensions. Fifteen formulations were prepared by the use of different combinations of surfa...

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...
