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.

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]
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 ...
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.
Drug delivery devices are specialized tools for the delivery of a drug or therapeutic agent via a specific route of administration. Such devices are used as part of one or more medical treatments . Contents
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 ...
In medicine, a subcutaneous implant is an implant that is delivered under the skin into the subcutaneous tissue by surgery or injection and is used to deliver a drug for a long period of time. [ 1 ] [ 2 ] Examples of drugs that can be administered in this way include leuprorelin and the sex steroids estradiol [ 3 ] and testosterone .
