A SHORT REVIEW ON TARGETED DRUG DELIVERY SYSTEM: FOCUS ON ADVANCED THERAPUETICS AND DIAGNOSIS

Abstract

Delivering a drug to supply its therapeutic effect in the targeted site of
diseased human tissue in a human body with low toxicity is known as
targeted drug delivery system. It has numerous advantages like
reducing the frequency of drug dosage of patients, also performing a
uniform therapeutic effect of a drug with reduced side effects and
toxicity. This system is also known as a "Smart drug delivery" Its
ultimate goal is to achieve pharmaceutical and therapeutic effects in
the system. Liposomes act as an important tool for targeted drug
delivery systems which is a long-circulating macromolecular carrier
with enhanced permeability and retention. This system mainly
concentrates on delivering the nanoparticles of a drug only in the
infected tissue without the interaction of healthy tissue. A Targeted
drug delivery system is widely used in cancer therapy treatments such
as chemotherapy to get the required therapeutic effect on the tumor.
