Despite their structural similarity to coumarin, the anticoagulants dicumarol and warfarin do not appear to be substrates for CYP2A6. The overall rate of dicumarol metabolism varied approx 5 fold among the human liver microsomal samples, but this variation correlated poorly (r2= 0.126) with the variation observed in CYP2A6 levels and hydroxycoumarin levels.

Dicumarol admin prolongs the half-life of chlorpropamide and phenytoin, resulting in hypoglycemia in the case of chlorpropamide and an increased plasma drug concn in the case of phenytoin.
Antipyrine (in vivo) & sulfinpyrazone (in vitro) have been reported to interact with warfarin and should be used cautiously in pt receiving anticoagulants. /anticoagulants/

Considerable individual variation in t/2 of dicumarol has been attributed to genetic factors. ... dicumarol...hydroxylated to inactive compounds by enzymes of hepatic endoplasmic reticulum. These metabolites and traces of parent drugs are excreted in urine. Some unabsorbed dicumarol appears in feces.
In man, absorption of dicumarol from gi tract is slow and erratic. ... There is considerable variation in absorption from one individual to another. Within circulation...almost entirely but loosely bound to plasma albumin, & only small percentage of total plasma concentration is represented by unbound drug. ... Appreciable amount ...found in erythrocytes, but little or none is present in cerebrospinal fluid. ...accumulate/s/ mainly in lung, liver, spleen and kidney.
Whole-body autoradiography of rats given anticoagulant, [(14)C]-dicumarol by intracardiac injection, indicated that (14)C distributed in most tissues, maximally in liver, lungs, heart, and kidneys. After 24 hr, (14)C levels were high in intestinal tract owing, presumably, to biliary excretion. Initially, iv dose of dicoumarol was more readily excreted in bile than in urine; in 3 hr, 4% was eliminated in bile and less than 0.4% in urine.
