Full description

Subjects were randomized in a 1:1 ratio to one of 2 T-R (R-T). That is, 8 subjects in the first cycle T group had fasting 1 tablet of test preparation (compound ibuprofen polyrelease tablet, specification: each containing ibuprofen 400 mg, diphenhydramine hydrochloride 50 mg, Overseas Pharmaceuticals, Ltd.; 8 subjects in the R group had fasting 1 ibuprofen tablet (200 mg) and 2 tablets of diphenhydramine hydrochloride (25 mg) with 240 ml warm water. Cross-administration after 7 days.

The 16 healthy subjects (including male and female subjects) were randomly divided into 2 groups, T-R and R-T, with 8 participants each. The selected subjects were admitted to the phase I ward of the clinical research center 1 day before each cycle and fasted for more than 10h before each cycle.

At 0 h (within 1.0 h before administration) and 5 min, 15 min, 30 min, 45 min, 1.0 h, 1.25 h, 1.5 h, 2.0 h, 2.5 h, 3.0 h, 3.5 h, 4.0 h, 4.5 h, 5.0 h, 5.5 h, 6.0 h, 7.0 h, 8.0 h, 9.0 h, 10.0 h, 12.0 h, 24.0 h, 36.0 h, and 48.0 h, Upper limb venous blood was collected at 25 time points, About 1.0 mL blood was discarded before each blood samples using intravenous indwelling needle, After each blood collection, About 4 mL of blood was collected into vacuum labeled EDTA-K2 anticoagulant.

The seated vital signs (including temperature, pulse, and blood pressure) were measured at 0 h before administration (within 1.0 h before administration) and 2.0 ± 0.5 h, 8.0 ± 0.5 h, 24.0 ± 1.0 h, 48.0 ± 1.0 h after administration. The subjects had a physical examination, vital signs, electrocardiogram and laboratory tests after the blood sampling. Medical staff during the study to observe and ask the subjects about subjective feelings and possible adverse events during the trial. If a subject has an AE during the study, the investigator should follow up the AE as far as possible until the adverse event response, or return to the screening period level, or the subject has stable condition.
