Absorption and excretion of a new antidepressive (SQ 10,996) in humans. 1976

R A Vukovich, and J Dreyfuss, and E C Schreiber, and E S Neiss

A single oral dose of 10 mg of SQ 10,996-14C was absorbed slowly by 3 normal male volunteers, with peak plasma concentrations achieved 6 hr after ingestion; the plasma half-life was about 38.5 hr. On average, 82.3 +/- 3.5% of the radioactivity present in the 2 hr plasma sample was bound to plasma proteins. These volunteers excreted an average of 31 and 52% of the dose in the urine and feces, respectively. All subjects excreted minor amounts of 14CO2 in the expired air. No unchanged SQ 10,996-14C was found in the urine. Three unidentified metabolites were excreted in urine. SQ 10,996-14C was excreted in the feces only as unchanged drug, suggesting that the drug is incompletely absorbed. The volunteers tolerated the drug well and experienced no adverse effects.

D000928 Antidepressive Agents Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems.
