Enantiomerical pharmacokinetic prevalence of (+) albendazole sulphoxide in Trichinella spiralis muscle larvae.

In a previous work, it was demonstrated that (+) albendazole sulphoxide (SOABZ) has higher anthelmintic activity than (-) SOABZ (Bolás-Fernández et al. J Parasitol 90:407-409, 2004). In this work, the pharmacokinetics characteristics of SOABZ and its enantiomeric forms were studied in an ex vivo model system for Trichinella spiralis isolated muscle larvae.

The effect of intestinal trichinellosis on oral bioavailability of albendazole in mice.

The effect of Trichinella spiralis infection on the pharmacokinetic profile of orally administered albendazol has been investigated in mice during the intestinal phase of the disease. Swiss CD-1 mice were orally infected with 300 +/- 50 muscle larvae of T. spiralis and then treated with albendazole (ABZ) formulated in hydroxy-propyl-beta-cyclodextrins at the dose of 10 mg/kg given orally on days 0, 5, 10 and 22 post-infection (p.
