Effect of Meloxicam Tablets on Bleeding Time in Healthy Subjects

A Double Blind, Randomized, Parallel Group Trial to Compare the Effect of Three Doses of Meloxicam Tablets (7.5, 15 and 30 mg) With Placebo on Bleeding Time in Healthy Subjects; With Extended-release Indomethacin Capsules 75 mg (Open-label) as an Active Control to Assess Trial Sensitivity.

The primary purpose of this study was to evaluate the effect of meloxicam tablets (7.5, 15 mg and 30 mg) with meloxicam placebo. Extended-release indomethacin capsules (75 mg) was an active control to assess trial sensitivity on bleeding time in healthy subjects. The secondary aim of this study was to assess effects of treatment on other platelet function and coagulation parameters.
