A method is described for monitoring the ingestion of isoniazid based on detecting its metabolites, isonicotinic acid, and isonicotinylglycine in the urine. The sensitivity of the method is high so that reliably positive results were obtained up to about 24 hours after the ingestion of 100 mg isoniazid. The method should facilitate monitoring the taking of isoniazid by tuberculosis patients and the use of isoniazid as a marker for assessing the regularity with which other drugs prescribed for self-administration are actually ingested.
本文描述了一种基于检测尿液中异烟肼代谢产物异烟酸和异烟酰甘氨酸来监测异烟肼摄入情况的方法。该方法灵敏度高,摄入100mg异烟肼后约24小时内均可可靠地获得阳性结果。该方法应有助于监测结核病患者服用异烟肼的情况,以及将异烟肼用作评估自行服用的其他处方药实际服用规律的标志物。
