The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue. The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system releases the drug in a dosage form.
Nanoparticle drug delivery systems are engineered technologies that use nanoparticles for the targeted delivery and controlled release of therapeutic agents. The modern form of a drug delivery system should minimize side-effects and reduce both dosage and dosage frequency. Recently, nanoparticles have aroused attention due to their potential ...
In 2018, the FDA approved Alnylam's siRNA drug Onpattro , the first drug to use LNPs as the drug delivery system. [ 4 ] [ 6 ] By that point in time, siRNA drug developers like Alnylam were already looking at other options for future drugs like chemical conjugate systems , but during the 2010s, the earlier research into using LNPs for siRNA ...
These devices are faster and more sensitive than typical drug delivery. [15] The efficacy of drug delivery through nanomedicine is largely based upon: a) efficient encapsulation of the drugs, b) successful delivery of drug to the targeted region of the body, and c) successful release of the drug. [16] Several nano-delivery drugs were on the ...
Drug delivery is a rapidly growing area that is now taking advantage of nanotube technology. Systems being used currently for drug delivery include dendrimers, polymers, and liposomes, but carbon nanotubes present the opportunity to work with effective structures that have high drug loading capacities and good cell penetration qualities.
Interest in targeted drug delivery has grown drastically due to its potential implications in the treatment of cancers and other chronic diseases. [23] [24] [25] In order to achieve efficient targeted delivery, the designed system must avoid the host's defense mechanisms and circulate to its intended site of action. [26]
Challenges in dual drug delivery include independently controlling release rates of each of the drugs loaded in the system. In a 2019 study by Damera et al., aquasomes were used to deliver bovine serum albumin (BSA) in combination with one of three therapeutic drugs ( Coumarin 153 , Warfarin , and Ibuprofen ), allowing release of a bioactive ...
Microspheres composed of dextran have several advantages as a drug delivery system including controlled drug release, localized drug concentration, and reduced adverse reactions. Controlled drug release by these dextran microparticles is achieved by degradation, which is the breakdown of chemical bonds in the molecular structure of the ...
