Drug-drug Interactions

AED-AED drug interactions

Administration of multiple AEDs is common in the ICU to manage refractory seizures and SE. Satisfactory seizure control is not achieved in 30–40% of patients with monotherapy, making it necessary to use two or more AEDs.[19,20] Although synergistic anticonvulsant activity between medications may be desirable, concurrent use of multiple AEDs generally increases the risk of drug interactions. Table 4 lists common AED-AED drug-drug interactions.

AED-nonAED interactions

Interactions of AEDs with other agents is seen more frequently with drugs that are metabolized in the liver, and therefore are more common with older AEDs. Table 5 and Table 6 describe AED-nonAED and nonAED-AED interactions.
