Abstract

See full text

The present invention provides methods and compositions for the treatment of ion imbalances using core-shell composites and compositions comprising such core-shell composites. In particular, the invention provides core-shell particles and compositions comprising potassium binding polymers, and core-shell particles and compositions comprising sodium binding polymers, and in each case, pharmaceutical compositions thereof. Methods of use of the polymeric and pharmaceutical compositions for therapeutic and/or prophylactic benefits are also disclosed. The compositions and methods of the invention offer improved approaches for treatment of hyperkalemia and other indications related to potassium ion homeostasis, and for treatment of hypertension and other indicates related to sodium ion homeostasis.
