Hyperkalemia, also spelled hyperkalaemia, is an elevated level of potassium (K⁺) in the blood serum. Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia. Typically this results in no symptoms. Occasionally when severe it results in palpitations, muscle pain, muscle weakness, or numbness. An abnormal heart rate can occur which can result in cardiac arrest and death.
This disclosure pertains to the field of medicinal chemistry and relates to pharmaceutical polymers for the treatment of hyperkalemia and methods for their preparation. Specifically, this document provides potassium-binding polymers prepared by polymerization of monomers and crosslinking agents, wherein the monomers are compounds of formula (V), and the crosslinking agents are compounds of formula (VI) and / or formula (VII), wherein the variables are as defined in this specification; this application relates to their use in the treatment or prevention of hyperkalemia.
