pH responsive drug delivery systems respond to the environmental pH of a tissue, which, when existing within a certain acidic range, can lead to structural and chemical changes of the drug delivery system. These changes can include conformational changes and surface interactions that can lead to the degradation or swelling/shrinking of the drug ...
Transdermal drug delivery systems may include stretch-triggered technology but these devices are typically used for long-term administration, making drug reloading a topic of concern. [11] Issues of environmental impact are also a concern when it comes to transdermal drug delivery due to the material's lack of ability to biodegrade and ...
This spring and the associated mechanical components form a one-shot linear actuator. [citation needed] When triggered the actuator drives a three-step sequence: [citation needed] accelerate the syringe forward, puncturing the injection site; actuate the piston of the syringe, injecting the drug; deploy a shield to cover the needle
Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
It’s a cruel joke of Kentucky’s system that getting locked up for a heroin overdose may be easier than getting a Suboxone prescription to prevent one. When the opioid epidemic hit, Mike Townsend, who has managed the Recovery Kentucky system for a decade, said he saw no reason to offer more than the existing 12-step program.
This is when the development of "smart drug delivery" originated. Encapsulated within the idea of smart drug delivery is the use of gated delivery systems. Researchers discovered that certain materials could be loaded and capped to prevent premature drug release. The caps could subsequently be removed using different external stimuli.
The drug is expelled via the laser-drilled hole visible on the left side of the tablet. The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it.
Preclinical research in fruit flies and cell cultures suggests that a dual-targeting drug could help prevent the accumulation of toxic tau buildup that is associated with Alzheimer's disease ...
