中文摘要

体外研究表明,阿米替林N-去甲基化为去甲替林主要由细胞色素P450- 3A 4介导,而阿米替林羟基化为10-羟基-阿米替林部分由P450- 2D 6介导。 该数据预测了联合使用酮康唑或奎尼丁(分别为3A 4和2D 6的高活性和相对特异性竞争性抑制剂)时阿米替林体内清除受损的可能性。 将在两项前瞻性双盲对照动力学-动力学研究中检验这一假设。
英文摘要
In vitro studies demonstrate that N-demethylation of amitriptyline to nortripty-line is mediated mainly by cytochrome P450-3A4, while hydroxylation of amitripty line to 10-hydroxy-amitriptyline is mediated in part by P450-2D6. This data pre-dicts the possibility of impaired clearance of amitriptyline in vivo by coadmin-istration of ketoconazole or quinidine, highly active and relatively specific competitive inhibitors of 3A4 and 2D6, respectively. This hypothesis will be tested in two prospective double-blind controlled kinetic-dynamic studies.
