Methoxy Polyethylene Glycols (mPEGs) are increasingly being applied in drug discovery and drug development to enhance the deliverability and bioavailability of the drug, and to increase the serum half-life. Today, due to advancements in chemical processes and purification techniques it is possible to produce high-quality mPEGs.

mPEGs in combination with a small molecule drug can negate the disadvantages of poor solubility, inefficient action on the target site, low presence in the bloodstream, and toxicity. When combined with a large molecule, they help increase the half-life, resident time in the blood and help prevent the immune system responses of the body from detecting the drug as an antibody.
