(en) Valdes et al concluded that their study, which examined the population pharmacokinetics of levetiracetam in a critically ill neurosurgical population, found that this population required higher doses to achieve target levels. The study also found that augmented renal clearance (ARC), a phenomenon characterized by creatinine clearance (CrCl) greater than 130 mL/min/1.73m2, is commonly described in critically ill patients, especially neurological ICU patients. A dose of at least 1000 mg of levetiracetam twice daily was required to lead to optimal results and reduced the odds of seizure by 68% compared with low-dose regimens (500 mg bid) [...]
