enteric coating controlled release and enteric release coatings

Uses

Methoxypolyethylene Glycol of with an average molecular mass of 350. Methoxypolyethylene Glycol (MPEG) is used in various applications such as micelles for drug delivery as well as in modifications of therapeutic proteins to improve their pharmacokinetics.

Uses

Methoxypolyethylene glycol 350 has been used in a study to assess the synthesis of a new class of thermosensitive micellar cyclotriphosphazenes. It has also been used in a study to investigate synthesis of a new amphiphilic poly(organophosphazene) by stepwise nucleophilic substitution.

Definition
