Pharmacological compositions, and methods for administration, of the type employing an iron oxide complex with a polyol or polyether. The methods of administration may comprise parenteral administration of an effective dose of the complex formulated in a biocompatible liquid delivered at a rate of from about 1 mL/sec to less than 1 mL/min and wherein upon administration the complex provides minimal detectable free iron in a subject, and minimal incidence of anaphylaxis. The pharmacological compositions are of the type employing a polyol or polyether iron oxide complex, which, upon parenteral administration to a subject, are substantially immunosilent, provide minimal anaphylaxis and minimal free iron, and undergo minimal dissolution in vivo.
药物组合物和给药方法,采用铁氧化物复合物与多元醇或聚醚。给药方法可能包括将经配制的复合物以生物相容液体的形式以每秒约1毫升至不到1毫升/分钟的速率进行肠道给药,其中在给药后,复合物在受试者体内提供最小可检测的游离铁,并且最小发生过敏反应。药物组合物采用多元醇或聚醚铁氧化物复合物的类型,经肠道给药给受试者后,基本上是免疫沉默的,提供最小的过敏反应和最小的游离铁,并且在体内发生最小的溶解。
