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 ...
New AI-powered technologies can be used to treat a range of long-term illnesses such as diabetes
A 2013 review found the cost of developing a delivery system was only 10% of the cost of developing a new pharmaceutical. [16] A more recent study found the median cost of bringing a new drug to market was $985 million in 2020, but did not look at the cost of developing drug delivery systems. [17]
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 ...
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]
Ultrasound-triggered drug delivery using stimuli-responsive hydrogels refers to the process of using ultrasound energy for inducing drug release from hydrogels that are sensitive to acoustic stimuli. This method of approach is one of many stimuli-responsive drug delivery-based systems that has gained traction in recent years due to its ...
