Polymer implant eluting drugs. Drug eluting implants encompass a wide range of bioactive implants that can be placed in or near a tissue to provide a controlled, sustained or on demand release of drug while overcoming barriers associated with traditional oral and intravenous drug administration, such as limited bioavailability, metabolism, and toxicity.

Bioprinting drug delivery is a method for producing drug delivery vehicles. It uses 3D printing of biomaterials.Such vehicles are biocompatible, tissue-specific hydrogels or implantable devices. 3D bioprinting prints cells and biological molecules to form tissues, organs, or biological materials in a scaffold-free manner that mimics living human tissue.
Systems used with pH-responsive polymers include implantable hydrogels and micro- and nanoparticles. pH-responsive drug delivery systems are particularly suitable for the design of chemotherapeutic delivery systems due to the naturally low pH found in tumor microenvironments, but can be applied in other disease settings where the pH of the ...
This technology calls for implantable drug delivery devices, in which the drug is injected into the 3D printed organ and is released once in vivo. [3] Also, organ printing has been used as a transformative tool for in vitro testing. [3] The printed organ can be utilized in discovery and dosage research upon drug-release factors. [3]
New AI-powered technologies can be used to treat a range of long-term illnesses such as diabetes
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.
Implantable drug delivery systems have also been developed to administer therapeutic agents that have poor bioavailability or require localized release and exposure at a target site. [73] Examples include a PDMS microfluidic device implanted under the conjunctiva for drug delivery to the eye to treat ocular diseases [ 74 ] and microchips with ...
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.
