The two FDA-approved drugs include Abraxane, an albumin nanoparticle carrying paclitaxel used for breast cancer, non-small cell lung cancer, and pancreatic cancer treatment. The second FDA-approved PNP is Ontak, a protein conjugate carrying L-2 and Diphtheria toxin used for cutaneous T-cell lymphoma.
Protein-bound paclitaxel, also known as nanoparticle albumin–bound paclitaxel or nab-paclitaxel, is an injectable formulation of paclitaxel used to treat breast cancer, lung cancer and pancreatic cancer, among others. Paclitaxel kills cancer cells by preventing the normal breakdown of microtubules during cell division.
Using LNPs for drug delivery was first approved in 2018 for the siRNA drug Onpattro. [4] LNPs became more widely known late in 2020, as some COVID-19 vaccines that use RNA vaccine technology coat the fragile mRNA strands with PEGylated lipid nanoparticles as their delivery vehicle (including both the Moderna and the Pfizer–BioNTech COVID-19 ...
Dextran conjugates are also utilized in nanoparticle drug delivery system formulations. Nanoparticles composted of dextran and stearic acid with a polyethylene glycol (PEG) coating can be loaded with antiviral drugs and be effectively internalized by cells. This nanosystem has the advantages of providing protection against immune responses and ...
Magnetic nanobeads or nanoparticle clusters composed of FDA-approved oxide superparamagnetic nanoparticles (e.g. maghemite, magnetite) hold much potential for waste water treatment since they express excellent biocompatibility which concerning the environmental impacts of the material is an advantage compared to metallic nanoparticles.
The first time the FDA approved the use of lipid nanoparticles as a drug delivery system was in 2018, when the agency approved the first siRNA drug, Onpattro. [65] Encapsulating the mRNA molecule in lipid nanoparticles was a critical breakthrough for producing viable mRNA vaccines, solving a number of key technical barriers in delivering the ...
To achieve this, PLGA is mixed with an organic water-miscible solvent approved by the Food and Drug Administration (FDA). Once the PLGA is mixed into the solvent with the drug of choice to create a homogeneous solution or suspension. When this mixture is injected, the PLGA solidifies due to water insolubility and is replaced by the water.
Altering vesicle size and surface chemistry can also be tuned to increase circulation time. Various FDA-approved liposomal drugs are in clinical use in the US. The anthracycline drug doxorubicin is delivered with phospholipid-cholesterol liposomes to treat AIDS-related Kaposi sarcoma and multiple myeloma with high efficacy and low toxicity. [37]
