Chemistry and pharmacology

Sevelamer is a copolymer of 2-(chloromethyl)oxirane (epichlorohydrin) and prop-2-en-1-amine. The marketed form sevelamer hydrochloride is a partial hydrochloride salt being present as approximately 40% amine hydrochloride and 60% sevelamer base. The amine groups of sevelamer become partially protonated in the intestine and interact with phosphorus molecules through ionic and hydrogen bonding.

Contraindications

Sevelamer therapy is contraindicated in hypophosphataemia or bowel obstruction.

Adverse effects
