Antepsin Pharmacology
Thalidomide is an immunomodulatory agent with a spectrum of activity that is not fully characterized. Thalidomide is racemic — it contains both left and right handed isomers in equal amounts: one enantiomer is effective against morning sickness, and the other is teratogenic. The enantiomers are converted to each other in vivo. That is, if a human is given D-thalidomide or L-thalidomide, both isomers can be found in the serum. Hence, administering only one enantiomer will not prevent the teratogenic effect in humans.
Antepsin Absorption
The absolute bioavailability has not yet been characterized in human subjects due to its poor aqueous solubility. In studies of both healthy volunteers and subjects with Hansen’s disease, the mean time to peak plasma concentrations (Tmax) ranged from 2.9 to 5.7 hours indicating that thalidomide is slowly absorbed from the gastrointestinal tract.
Antepsin side effects and Toxicity
The R-configuration and the S-configuration are more toxic individually than the racemic mixture. The LD50 could not be established in mice for racemic thalidomide, whereas LD50 values for the R and S configurations are reported to be 0.4 to 0.7 g/kg and 0.5 to 1.5 g/kg, respectively.
