Can Drug Release Rate from Implants Be Tailored Using Poly(urethane) Mixtures?
Hydrophobic and hydrophilic thermoplastic poly(urethane) (TPU) mixtures offer the opportunity to tune water swelling capacity and diffusion rate for drugs exhibiting broadly different properties. We sought to (1) assess the range of drug diffusion rates achieved by varying hydrophilic-to-hydrophobic…
