Nevertheless, we have successfully solubilized the majority of the hydrophobic drugs in the library specifically, 11 out of 21 drugs exhibited the loading capacity > 20 wt.% (Table ), which is typical upper limit for many systems reported in the literature. Even for those that did not perform well, the apparent solubility was still in most cases higher then previously reported in literature. Similar to previously reported POx based triblock copolymers formulation , we anticipate that variety of formulations presented herein will allow the parenteral administration and will help to alleviate the problem associated with the use of hydrophobic drugs like, poor pharmacokinetics and use of toxic excipients for parenteral administration, overall improving the therapeutic outcomes of treatment.
