The metabolism and elimination of 14C-labelled trimethylamine and its N-oxide (100 mg orally) were studied in three male volunteers. For both compounds the urine was the major route of elimination, with 95% of the administered 14C being voided in the first 24 h. No radioactivity was found in expired air. The majority (greater than 95%) of the urinary 14C from both compounds was excreted as trimethylamine N-oxide.
在三名男性志愿者中研究了14C标记的三甲胺及其N-氧化物（口服100毫克）的代谢和消除情况。对于这两种化合物，尿液是主要的消除途径，给药的14C中有95%在最初24小时内排出。呼出气体中未发现放射性。两种化合物的尿中14C大部分（超过95%）以三甲胺N-氧化物的形式排泄。
