What is Plga Peg?
Biodegradable thermosensitive polymer, poly(dl-lactide-co-glycolide-b-ethylene glycol-b-dl-lactide-co-glycolide) (PLGA-PEG-PLGA) is a desirable ophthalmic drug delivery system because it can be formulated into injectable solution which forms gel in situ to provide prolonged drug release.
Why is PLGA used in nanoparticles?
Poly (lactic-co-glycolic acid) (PLGA) is one of the most effective biodegradable polymeric nanoparticles (NPs). It has been approved by the US FDA to use in drug delivery systems due to controlled and sustained- release properties, low toxicity, and biocompatibility with tissue and cells.
How are PLGA nanoparticles made?
To produce PLGA nano-scale particles by continuous phase flow, an organic mixture of polymer and drug is assisted by a flow of aqueous phase solution on both sites along the microchannel, and the precipitation takes place in the organic phase (Figure 2D).
What is PLGA made of?
Polyester PLGA is a copolymer of poly lactic acid (PLA) and poly glycolic acid (PGA). It is the best defined biomaterial available for drug delivery with respect to design and performance.
Is PLGA a hydrogel?
PLGA–PEG–PLGA (PPP) triblock copolymer is the most widely studied thermosensitive hydrogel owing to its non-toxic, biocompatible, biodegradable, and thermosensitive properties.
What is PLGA used for?
As described, PLGA is an FDA-approved elastomeric copolymers for drug delivery owing to its biodegradability, biocompatibility, mechanical properties and ease of processing. It has been used in the production of a variety of vascular tissue–engineering devices, such as grafts and prosthetic devices.
Why is PLGA used for drug delivery?
PLGA is the most successful and most characterized polymer for controlled release drug delivery systems. It is favored because of its biocompatibility, biodegradability and mechanical strength and continues to be used to develop new controlled release systems.
Is PLGA safe?
Being biocompatible, PLA and PLGA produce safe and non-toxic degradation products which made them good candidates for many medical and pharmaceutical applications (Alsaheb et al. 2015).
What is Plga made of?
Is PLGA a natural or synthetic?
PLGA is a biodegradable aliphatic polyester-based polymer that comprises a synthetic copolymer of lactic acid (α-hydroxy propanoic acid) and glycolic acid (hydroxy acetic acid).

Is PLGA FDA approved?
Co-polymer poly(lactic-co-glycolic acid) (PLGA) nanotechnology has been developed for many years and has been approved by the US FDA for the use of drug delivery, diagnostics and other applications of clinical and basic science research, including cardiovascular disease, cancer, vaccine and tissue engineering.
Is PLGA used as vehicle in gene therapy?
This study presents an effective gene delivery vehicle, PLGA-based nanoparticle, which may contribute to the gene therapy for tumor and other miRNA-related diseases such as diabetic, cardiovascular disease, and neurodegenerative diseases.
Is PLGA toxic?
Although PLGA nanoparticles did not trigger significantly lethal toxicity up to a concentration of 300 μg/ml, the TNF-α release after the stimulation of PLGA nanoparticles should not be ignored especially in clinical applications.
