Absorption, Distribution and Excretion

The pharmacokinetics of chlorendic anhydride was evaluated in 4 male and 8 female Holzman's albino rats that ingested 14C-chlorendic anhydride via gavage in a single dose of 3.65 (Group 1: 2 females), 4.00 (Group 2: 4 females), 5.55 (Group 3: 2 females) or 3.62 mg/kg (Group 4: 4 males). Blood was drawn from females treated with 4 mg/kg at 1, 4, 8, 17, 24, 48, 72 and 96 hr after dosing. Urine and feces were collected daily in the Group 1, 3 and 4 rats. Animals were sacrificed 17, 96, 192 and 192 hr, respectively, after treatment, and selected tissues were excised. Regardless of sex, the primary route of excretion was the feces, 70% of the administered dose being eliminated within the first 72 hr. Only 10% of the administered dose was eliminated in the urine. After 192 hr, the maximum residues present in any tissue were <0.1 mg/kg, with the exception of the fat (0.121 mg/kg) and liver (0.296 mg/kg). The blood concentration of chlorendic anhydride peaked 1 hr after dosing and was significantly decreased by 96 hr. The absorption of chlorendic anhydride followed the two-compartment open model. The first compartment was suggested to consist of the blood and selected tissues which equilibrated rapidly, while the second compartment consisted of the fat which was slow in equilibrating and considered a deep reservoir.
