Abstract: An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (Tg) of the SMP foam to below 25° C. Other embodiments are described herein.

Abstract: An amorphous solid dispersion includes a linear poly(acrylic acid) and an active pharmaceutical ingredient. The linear poly(acrylic acid) used to form the amorphous solid dispersion has a Brookfield viscosity of at least 100 cP at 25° C. A method of forming such an amorphous solid dispersion of an active pharmaceutical ingredient includes forming a liquid dispersion of a linear poly(acrylic acid), an active pharmaceutical ingredient, and a solvent system, the linear poly(acrylic acid) having a Brookfield viscosity at 25° C. of at least 100 cP and evaporating the solvent system from the liquid dispersion to form an amorphous solid dispersion.
