The aim of the study was to compare the bioavailability of two formulations of meloxicam given to healthy volunteers and to demonstrate bioequivalence. The test product, Reumoxicam® 15 mg tablets (Farmak PJSC, Ukraine), given in a single dose was compared with a licensed reference product Movalis 15 mg tablets ("Boehringer Ingelheim Ellas A.E.", Greece), in a randomized, laboratory-blind, single dose, two periods, crossover study.

The secondary objective of the trial was to investigate the safety of both preparations on the basis of safety clinical and laboratory examinations (at the beginning and at the end of the trial) and registration of adverse events and/ or adverse drug reactions.

Randomized, single-dose, crossover, two-period, two-sequence, laboratory-blinded, comparative bioavailability study of test medicinal product Reumoxicam® 15 mg tablets (PJSC "Farmak", Ukraine) and reference medicinal product Movalis 15 mg tablets ("Boehringer Ingelheim Ellas A.E.", Greece) in healthy volunteers under fasting condition.

During each period 18 blood samples were taken: before dosing (0) and then at: 0.5; 1; 2; 3; 4; 4.5; 5; 5.5; 6; 7; 8; 10; 12; 24; 36; 48 and 72 hours after dosing.
