1 It can be stated in regard to the metabolism of nomifensine that the metabolites and also the starting compound are present in alkaline urine almost completely in conjugated form. 2 The metabolites M I-M III represent about 30% of the radioactivity excreted with urine. Two-thirds are N-glucuronides and one-third O-glucuronides. 3 Nearly the entire remainder of the renally eliminated radioactivity in nomifensine which is present in conjugated form as N-glucuronide. 4 Thus over 90% of the metabolites formed in man and excreted via urine have been identified.
