Comparative study of the potential of poly(2-ethyl-2-oxazoline) as carrier in the formulation of amorphous solid dispersions of poorly soluble drugs [PDF]

open access: yes, 2019
Despite the fact that solid dispersions are gaining momentum, the number of polymers that have been used as a carrier during the past 50 years is rather limited.
