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.
Overall, microdroplet-based drug delivery systems show great promise for revolutionizing medicine with significant potential for targeted drug delivery. Limitations Nevertheless, it is essential to note some common challenges associated with microdroplet-based drug delivery systems, including their biocompatibility, toxicity, and scalability. [2]
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 ]
Though immunoliposomes serve as a possible advancement, there are other therapies similar to it that trail on the role of targeted drug delivery systems. [19] One example of such therapy is Immune Polymeric nanoparticles, which are similar to liposomes but consist of small particles composed of biodegradable polymers. [19] These nanoparticles ...
In the field of drug discovery, retrometabolic drug design is a strategy for the design of safer drugs either using predictable metabolism to an inactive moiety or using targeted drug delivery approaches. The phrase retrometabolic drug design was coined by Nicholas Bodor. [1]
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.
These smart drug delivery systems are able to deliver the drug with minimal leakage, can be actively or passively targeted to different areas within the body, and will only release drug in the presence of certain triggers, creating a sustained local response and accumulation of drug at the disease area.
