Effect of gamma radiation on combination therapy of certain antiepileptic drugs in rats.

The current study was designed to estimate the effect of υ-radiation on male rats pretreated with Levetiracetam (LEV) and/or Oxcarbazepine (OXC). Poly-treatment of rats with LEV, OXC and υ-radiation showed a significant elevation in the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and isoenzyme creatinine kinase-MB (CK-MB) along with, an increase in the level of creatinine, urea, cardiac troponin (cTnI) and glutamate. These increases were associated with a decrease in acetylcholine (Ach) and υ-aminobutyric acid (GABA) levels.
