Methoxy polyethylene glycol (mPEG) with high molecular weight which has been used as a coating agent in drug delivery systems leads to more therapeutic efficacy. This supports the hypothesis that coating the drugs with higher molecular weight of PEG derivatives. The coating agent, methoxy polyethylene glycol propionaldehyde 20KDa (mPEG-ALD 20KDa), is a new platform technology for pharmaceutical research in drug delivery.
