How do lacosamide and pregabalin differ on the record?
How each works, in its label's words: Lacosamide, “The precise mechanism by which VIMPAT exerts its antiepileptic effects in humans remains to be fully elucidated.”; Pregabalin, “LYRICA (pregabalin) binds with high affinity to the alpha 2 -delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues.”
Half-life, in each label's words: Lacosamide, “The maximum lacosamide plasma concentrations occur approximately 1-to-4-hour post-dose after oral dosing, and …”; Pregabalin, “12.3 Pharmacokinetics Pregabalin is well absorbed after oral administration, is eliminated largely by renal excretion …”
Generics: lacosamide since 2022; pregabalin since 2019 (Drugs@FDA).
