tv fjsr � � peg chains had little influence on platypuss a href allegra drug a the encapsulation efficiency of methotrexate, but platypuss a href allegra drug a affected the release rate a similar construct between peg chains and ����� was utilized to deliver the anticancer drug fluorouracil encapsulation of fluorouracil into g = ����� dendrimers with carboxymethyl peg surface chains revealed reasonable drug loading, a reduced release rate, and reduced hemolytic toxicity compared to the nonpegylated dendrimer fig etoposide, mefenamic acid platypuss a href allegra drug a diclofenac, and venlafaxine the combination between dendrimers and hydrophilic and or hydrophobic polymer chains has recently been extended to solubilize the hydrophobic anticancer platypuss a href allegra drug a drug etoposide a star polymer composed platypuss a href allegra drug a of amphiphilic block copolymer arms has platypuss a href allegra drug a been synthesized and characterized the core of the star polymer was a generation two pamamoh dendrimer, the inner block of the arm a lipophilic polyecaprolactone pcl and the outer block of the arm a hydrophilic peg the starpcl polymer was synthesized first by ringopening polymerization of ecaprolactone with the pamamoh dendrimer as initiator the peg polymer was then attached to the pcl terminus by an platypuss a href allegra drug a esterforming reaction characterization with sec, h nmr, ftir, tga, and dsc confirmed the star structure of the polymers a loading capacity of up to platypuss a href allegra drug a ww was achieved with etoposide a

generations were applied to encapsulate small molecule drugs such as platypuss a href allegra drug a mefenamic acid and diclofenac the formulations were stored at room temperature for up to ten months

hydrolyzable ester bond and the incorporation of this drugdendrimer complex into a platypuss a href allegra drug a semiinterpenetrating network of an acrylamide hydrogel has been studied as a novel drug delivery formulation to avoid the currently necessary multiple daily administration of the antidepressant the effect of peg concentration and molecular weight was studied to find optimal release
