Novel drug delivery system, an area of present research is used to carry pharmaceutical ingredients to a targeted site
of action in a body, without affecting the nature of the drug. Nanoparticles are too small in size; it has a drug size
of 10â€“100 nm due to its drug size a large amount of drug is absorbed through blood. Polylactide-co-glycolic acid
(PLGA) is a synthetic polymer; it has several lactic acids in the unit and several glycolic acids in the unit. PLGA is
used with the drug for improved bioavailability and it works on the targeted site of action. It is used as a polymer
with the drug which is having less half-life period. The PLGA has been approved by the department of FDA.
The PLGA nanoparticles are prepared by the nano-emulsion method and nanoprecipitation method. The PLGA-
loaded nanoparticles are administered through various routes of administration such as oral, parenteral, nasal, and
transdermal. It is used to treat several diseases such as Alzheimerâ€™s, diabetes, and cancer. The evaluation of PLGA
nanoparticles has been done with Fourier transform infrared, differential scanning calorimetric, scanning electron
microscopy, transmission electron microscopy, etc. PLGA is a biodegradable polymer possessing superiority
over other polymers in targeting the disease. This review aims in pooling the nanoparticles prepared using the
biodegradable PLGA polymer and its efficiency in targeting the drug.
