Cyclodextrin-based controlled drug release system.
Because of their bioadaptability and multi-functional characteristics, cyclodextrins (CDs) are capable of alleviating the undesirable properties of drug molecules in various routes of administration through the formation of inclusion complexes. This article outlines the current application of natural and chemically modified CDs in the design of advanced dosage forms. In an oral drug delivery sy...
متن کاملpH Sensitive Hydrogel Based Acrylic Acid for Controlled Drug Release
Hydrogels, due to their unique potentials such as high-water content and hydrophilicity are interest for the controlled release of drug molecules. The present study aims to create a controlled-release system through the preparation and characterization of hydrogels based on pH-sensitive polymers such as poly (acrylic acid). Poly (acrylic acid), p(AA), hydrogel has been synthesized by radical po...
متن کاملDrug Delivery: Controlled Release
Over the past decades, the treatment of illness has been accomplished by administering drugs to the human body via various pharmaceutical dosage forms, like tablets. These traditional pharmaceutical products are still commonly seen today in the prescription and over-the-counter drug marketplace. To achieve and maintain the drug concentration in the body within the therapeutic range required for...
متن کاملControlled Drug Release Asymptotics
The solution of Higushi’s model for controlled release of drugs is examined when the solubility of the drug in the polymer matrix is a prescribed function of time. A time-dependent solubility results either from an external control or from a change in pH due to the activation of pH immobilized enzymes. The model is described as a one-phase moving boundary problem which cannot be solved exactly....
متن کاملPolyurethane membrane with porous surface for controlled drug release in drug eluting stent
BACKGROUND Membrane covered drug eluting stents (DES) were prepared to prevent tumor ingrowth and to control drug release. Polyurethane (PU) is commonly used for DES coating material because of high tensile strength. The release of paclitaxel (PTX) may increase from porous PU membrane. RESULTS Polyethylene glycol (PEG) was incorporated into PU membranes to form porous structure and control th...
