cation exchange resin  see ion exchange r.

cholestyramine resin  a synthetic, strongly basic anion exchange resin in the chloride form which chelates bile acids in the intestine, thus preventing their reabsorption; used as an adjunctive therapy to diet in management of certain hypercholesterolemias and in the symptomatic relief of pruritus associated with bile stasis.

composite resin  a synthetic resin, usually acrylic based, to which a high percentage of inert filler has been added, e.g., coated glass or silica; used chiefly in dental restorations.

epoxy resin  a heat-set resin with toughness, adhesibility, chemical resistance, dielectric properties, and dimensional stability; several modified types are used as denture base material.

ion exchange resin  a high-molecular-weight insoluble polymer of simple organic compounds capable of exchanging its attached ions for other ions in the surrounding medium; classified as (a) cation or anion exchange r's, depending on which ions the resin exchanges; and (b) carboxylic, sulfonic, etc., depending on the nature of the active groups.

podophyllum resin  podophyllin; a mixture of resins from podophyllum, used as a topical caustic in the treatment of certain papillomas, condylomata acuminata, keratoses, and other epitheliomas.
