Chronopharmacology of the New Uricosuric Diuretic S-8666 in Rats

[摘要] References(15)Cited-By(1)A new loop diuretic with uricosuric activity, 6, 7-dichloro-5-(N, N-dimethylsulfamoyl)-2, 3-dihydro-2-benzofuran carboxylic acid (S-8666), was given orally at 12:00 a.m. or 12:00 p.m. in rats. The diuretic of S-8666 and the urinary excretions of the drug and its active metabolite S-8680 (N-demethyl S-8666) were greater at 12:00 a.m. than at 12:00 p.m.. Thus, the present study indicates that the diuretic effects of S-8666 varies with its administration time. Time-dependent variations in the amount of urinary excretions of S-8666 and S-8680 might be involved in the mechanisms for this phenomenon.
