Levetiracetam is an antiseizure medication prescribed to treat epilepsy. This study aimed to evaluate the bioequivalence
between two formulations of levetiracetam coated tablets in order to meet regulatory requirements for marketing
in Brazil. An open-label, randomized, single-dose, two-period, two-sequence, two-treatment crossover study was
conducted in Brazilian healthy subjects of both genders. Subjects received a single dose of Levetiracetam 1000 mg
test tablet (Zodiac Produtos Farmacêuticos S.A) and reference product (Etira®, Aché Laboratórios Farmacêuticos
S.A.) under fasting conditions according to a randomly assigned order with a 7-day washout period. Serial blood
samples were collected up to 36 h post-dose. Plasma concentrations of levetiracetam were obtained by a validated
liquid chromatography-tandem mass spectro.. View more»
