Pharmacokinetics of the mycotoxin penicillic acid in male mice: absorption, distribution, excretion, and kinetics.

The pharmacokinetics of penicillic acid (PA), a carcinogenic mycotoxin, was investigated in male mice. Absorption of PA after po administration of [14C]PA was rapid. Only a small percentage of the radioactivity in the plasma was unchanged PA. After ip or iv administration of [14C]PA (90 mg/kg), blood, liver, kidneys, intestine, lungs, heart, and spleen contained the largest amounts of radioactivity while brain tissue accumulated the least. Over 90% and approximately 60% of the administered radioactivity was excreted in the urine after iv and ip injection, respectively, but essentially no unchanged PA was detected in the urine. Over 25% of the administered radioactivity following an iv dose of [14C]PA (90 mg/kg) was excreted in the bile in 60 min; no unchanged PA was detected in the bile. The excretion of radioactivity in the bile was decreased in diethyl maleate-pretreated mice. Only a small amount of the administered radioactivity was recovered in the feces and as expired CO2. The unchanged PA concentration-time curve in plasma was best fit by three, two, and one compartment open models after iv, ip, and po administration, respectively. Based on these results, it was concluded that metabolism and not excretion of unchanged parent penicillic acid is the major process of elimination of PA from the blood. There are extensive route-dependent differences in the kinetic behavior of PA.[1]
