Fasted Bioequivalence Study of 2 Olanzapine Film-coated Tablets, 5 mg, in Healthy, Adult Male and Female Subjects.

A comparative, open-label, randomized, two-period, two-treatment, two-sequence, two-way crossover clinical trial to evaluate the bioequivalence of single doses of test product Olanzapine film-coated tablets 5 mg (JSC Farmak, Ukraine) and reference product Zyprexa® coated tablets 5 mg (Eli Lilly, Nederland B V) in healthy, adult male and female subjects under fasted conditions.
