1. a solid or semisolid organic substance exuded by plants or by insects feeding on plants, or produced synthetically; they are insoluble in water but mostly soluble in alcohol or ether. adj., adj res´inous.
2. a compound made by condensation or polymerization of low-molecular-weight organic compounds.
acrylic r's products of the polymerization of acrylic or methacrylic acid or their derivatives, used in fabrication of medical prostheses and dental restorations and appliances.
anion exchange resin see ion-exchange resin.
cation exchange resin see ion-exchange resin.
cholestyramine resin a synthetic, strongly basic anion exchange resin in the chloride form which chelates bile salts 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 ceramic reinforcing filler has been added, such as particles of glass or silica coated with a coupling agent to bind them to the matrix; used chiefly in dental restorations. Called also composite.
epoxy resin a tough, chemically resistant, adhesive, flexible, dimensionally stable resin of epoxy polymers; 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 resins, depending on which ions the resin exchanges; and (b) carboxylic, sulfonic, and so on depending on the nature of the active groups.
an anion exchange resin used to bind dietary cholesterol and hence prevent its systemic absorption. Used to treat hypercholesteremia. Can bind many acidic drugs in the gastrointestinal tract and prevent their absorption.
an ion-exchange resin and antihyperlipemic agent.
indications It is prescribed for oral administration to increase bile acid excretion in the stool, for the treatment of hyperlipoproteinemia, and for pruritus resulting from partial biliary obstruction.
contraindications Complete biliary obstruction or known hypersensitivity to this drug prohibits its use.
adverse effects Among the more serious adverse reactions are fecal impaction, GI disturbances, and depletion of vitamins A, D, and K. Constipation is common. It interferes with the absorption of many other drugs, so other medicines should be given 1 hr before or 4-6 hr after cholestyramine.
cho·le·styr·a·mine res·in(kō-lestĕr-ă-mēn rezin)
Anion exchange resin used to bind dietary cholesterol and prevent its systemic absorption. Used to treat hypercholesteremia.
1. a solid or semisolid, amorphous organic substance of vegetable origin or produced synthetically. True resins are insoluble in water, but are readily dissolved in alcohol, ether and volatile oils.
products of the polymerization of acrylic or methacrylic acid or their derivatives and used in the fabrication of surgical prostheses and equipment.
see ion-exchange resin.
see ion-exchange resin.
a synthetic, strongly basic anion-exchange resin in the chloride form which chelates bile salts in the intestine, thus preventing their reabsorption.
usually a mixture of organic matrix and inorganic filler, used in restorative dentistry.
ipomoea resin, jalap resin, scammony resin
severe cathartics and irritants; little used because of their disastrous effects.
