چکیده انگلیسی
Intravenously administered (i.v.) drug-cyclodextrin (CD) inclusion complexes are generally expected to dissociate rapidly and completely, such that the i.v. pharmacokinetic profile of a drug is unchanged in the presence of CD. The altered pharmacokinetics of a synthetic ozonide in rats has been attributed to an unusually high-binding affinity (2.3 à 106 Mâ 1) between the drug and sulfobutylether7-β-cyclodextrin (SBE7-β-CD) with further studies suggesting a significant binding contribution from the adamantane ring. This work investigated the binding affinity of three adamantane derivatives [amantadine (AMA), memantine (MEM) and rimantadine (RIM)] to SBE7-β-CD and the impact of complexation on their i.v. pharmacokinetics. In vitro studies defined the plasma protein binding, as well as the impact of SBE7-β-CD on erythrocyte partitioning of each compound. SBE7-β-CD binding constants for the compounds were within the typical range for drug-like molecules (102-104 Mâ 1). The pharmacokinetics of AMA and MEM were unchanged; however, significant alteration of RIM plasma and urinary pharmacokinetics was observed when formulated with CD. In vitro studies suggested two factors contributing to the altered pharmacokinetics: (1) low plasma protein binding of RIM, and (2) decreased erythrocyte partitioning in the presence of high SBE7-β-CD concentrations. This work demonstrated the potential for typical drug-cyclodextrin interactions to alter drug plasma pharmacokinetics.
