Shear drug delivery

The use of shear stress for targeted drug delivery.

Stenosed segments of arteries significantly alter the blood flow known from healthy vessels. In particular, the wall shear stress at critically stenosed arteries is at least an order of magnitude higher than in healthy situations. This alteration represents a change in physical force and might be used as a trigger signal for drug delivery. Mechano-sensitive drug delivery systems that preferenti...

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...

Drug delivery.

What we know: In preschool children, small-volume spacers perform better than large-volume spacers. Detergent is the best antistatic agent for spacers, increasing lung delivery two- to threefold, but it must not be rinsed off. A mouthpiece should be used in children aged 2-3 years or older, as lung delivery is two- to threefold higher for oral inhalation than nasal inhalation (ie, by mask). Inh...
