Characterization of formulation parameters affecting low molecular weight drug release fromin situforming drug delivery systems

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...

LITERATURE ON CONTROLLED RELEASE DRUG DELIVERY SYSTEMS (MICROCAPSULES AND MATRIX TABLETS) Controlled release drug delivery systems

Controlled release drug delivery systems 1 are those dosage formulations designed to release an active ingredient at rates, which differ significantly from their corresponding conventional dosage forms. The controlled release drug delivery systems are aimed at controlling the rate of drug delivery, sustaining the duration of therapeutic activity and/or targeting the delivery of the drug to a ti...

Kinetic modeling on drug release from controlled drug delivery systems.

In this paper we review the mathematical models used to determine the kinetics of drug release from drug delivery systems. The quantitative analysis of the values obtained in dissolution/release rates is easier when mathematical formulae are used to describe the process. The mathematical modeling can ultimately help to optimize the design of a therapeutic device to yield information on the effi...
