Conjugation of Ibuprofen to Poly Ethylene Glycol and In-vitro drug release evaluation

Abstract
Polymers have become an integral part of drug delivery systems due to their improved pharmacokinetics properties. Polymer conjugation is a well-known and widely exploited technique useful to improve therapeutic properties of peptides, proteins, small molecules and oligonucleotides. Polymer conjugated drug generally exhibit prolonged half-life, higher stability, water solubility, lower immunogenicity, antigenicity and often also to the specific targeting tissue. Polymer materials are designed to be capable of delivering active substance. to the target diseased tissues and cells. Conjugation of Ibuprofen and polyethylene glycol (PEG) helps to increase the duration of action of the parent drug. The PEG-Ibu conjugates were synthesized from ibuprofen and PEG with two different molecular weights by esterification in the presence of DCC and DMAP. The PEG-Ibu conjugation characterized by FT-IR, UV, DSC and NMR and also in-vitro drug release study in different buffer at different ph.
