Effect of Steady State Meloxicam on Low Dose Aspirin Induced Inhibition of Platelet Aggregation and Thromboxane Synthesis in Healthy Males and Females

Effect of Steady State Meloxicam 15 mg/Day on Low Dose Aspirin (100 mg/Day) Induced Inhibition of Platelet Aggregation and Thromboxane Synthesis in Healthy Males and Females. An Open, Randomised, Two-way Crossover Study.

The objective of this study was to investigate the influence of meloxicam on low dose aspirin induced inhibition of platelet aggregation and thromboxane B2, when meloxicam is given before aspirin.
