Poly Drug Use - A Challenge for Drug Treatment

Poly-drug use refers to the use of two or more substances at the one time or repeatedly. It is common among both recreational and regular drug users across the world. Poly-drug use is a great contributor to the global number of deaths related to drug overdose. In this case, the likelihood of drug overdose and its pertaining complications in an individual is higher especially when benzodiazepine...

pH 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...

Drug 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...

Controlled 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....
