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. The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug ...
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.
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 ...
Targeted drug delivery systems facilitate the selective delivery of therapeutic agents to specific disease sites while minimizing off-target effects. These systems employ strategies, such as nanoparticles , liposomes , and micelles , to encapsulate drugs and enhance their stability, solubility, and bioavailability. [ 15 ]
Ligand-targeted liposomes are a promising method of drug delivery. These systems are efficient in delivering the drug to localized areas with low peripheral distribution, which minimizes off-target effects. The favorable biodistribution to target tissue is an encouraging property of this drug delivery system.

For instance, by conjugating the RNA aptamer to a drug compound, the RNA aptamer can act as a targeted delivery system for that drug. [7] Such RNA aptamers are known as ApDCs. [7] Additionally, through conjugation to radioisotope or a fluorescent dye molecule, RNA aptamers may be useful in diagnostic imaging. [7] [104] [105]
A map claiming to show the areas of the US that may be targeted in a nuclear war that originally circulated in 2015 is making the rounds again, amid the Russian war in Ukraine.. The map indicates ...
