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P450-3A4介导,而阿米替林羟化为10-羟阿米替林部分由P450-2D6介导。这些数据预测了酮康唑或奎尼丁(分别是3A4和2D6的高活性和相对特异性的竞争性抑制剂)在体内对阿米替林清除受损的可能性。这一假设将在两项前瞻性双盲对照动力学研究中得到验证。
英文摘要
In vitro studies demonstrate that N-demethylation of amitriptyline to nortriptyline is mediated mainly by cytochrome P450-3A4, while hydroxylation of amitriptyline to 10-hydroxy-amitriptyline is mediated in part by P450-2D6. These data predict the possibility of impaired clearance of amitriptyline in vivo by coadministration 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.
