Niosomes are nanosized vesicles made up of nonionic surfactants and cholesterol that kind when these compounds are dispersed within an aqueous medium. These lipid-based buildings are just like liposomes but vary in their composition, as niosomes use nonionic surfactants as an alternative to phospholipids. The exceptional characteristic of niosomes lies within their capability to encapsulate both hydrophilic and hydrophobic drugs in their bilayer membrane.
Distinct controlled drug delivery systems are outlined which include transdermal drug delivery systems, pulmonary drug delivery, and gastroretentive drug delivery systems. Advantages and drawbacks of assorted techniques can also be mentioned.
Some important benefits of these routes contain quick onset of motion, avoidance of to start with-pass metabolism, and improved bioavailability more than oral delivery. Delivery procedures include liquid formulations, metered-dose pumps, dry powder inhalers, and nebulizers. Over-all, the doc outlines the anatomical features and absorption pathways inside the nose and lungs, and reviews distinct systems for providing drugs by means of these
This document summarizes different oral controlled release drug delivery systems. It describes steady release systems that release drug about an extended period of time along the GI tract, including dissolution controlled, diffusion controlled, and combined dissolution/diffusion controlled systems.
It then handles subject areas like continual condition ideas, diffusion mechanisms, dissolution designs and polymer characterization as they relate to sustained check here and controlled release drug delivery. Analysis strategies for sustained release and controlled release tablets will also be outlined.
