Levetiracetam Foods

Drug/Food Interactions Food does not affect the extent of absorption of levetiracetam, but it decreases C ax by 20% and delays T ax by 1 -5 hours. 

Oral absorption of levetiracetam is nearly complete it is rapid and unaffected by food, with peak plasma concentrations in 1.3 hours. Kinetics are linear. Protein binding is less than 10%. The plasma half-life is 6-8 hours and may be longer in the elderly. Two thirds of the drug is excreted unchanged in the urine, and no active metabolites have been found. 

S-(-)-levetiracetam displays rapid and complete absorption, although food slows the rate but not the extent of absorption. It... 

The oral absorption of levetiracetam is not significantly affected by food. 

Chiral separations are particularly important for biologically active chiral compounds (e.g., pesticides) where the active ingredient is only one enantiomer. Chiral separations have been used to track biological degradation rates and changes in source characteristics. GC-based applications include chiral chordane and a-HCH in the polar bear food chain and levetiracetam and its enantiomer in dog plasma and urine whilst LC applications include amino acids in water and chiral aroma compounds in alcoholic drinks.
