Deteriorating Hemostatic Functions of Adult Female Wistar Rats Mediated by Activities of Non-Steroidal AntiInflammatory Drugs (NSAIDs) - Piroxicam and Vitamin E.

The status of hemostatic parameters, are useful physiological markers of organ and tissue damage anddysfunction. This study investigated the effect of Piroxicam on some hemostatic parameters of albino Wistar rats. Twentyfour (24) female albino Wistar rats were used for this study, they were randomly divided into four (4) groups of six (6) ratseach. Group A served as control, Group B and C were rats treated with 0.1 mg/kg and 0.2 mg/kg piroxicam while Group Dserved as 0.2 mg/kg piroxicam treated rats administered with Vitamin E. The experiment lasted for a period of 4 weeks, afterwhich the rats were euthanized. Blood sample was collected for measurement of bleeding time, clotting time, fibrinogenlevel and platelets count. One-way ANOVA was used to compare, means and a p<0.05 was considered significant.

RESULT: Data generated showed that Piroxicam significantly (p<0.05) decreased the clotting time, platelets count and fibrinogen level.Piroxicam also significantly (p<0.05) increased the bleeding time level of the rats. Co-administration of Vitamin Esignificantly (p<0.05) increased the bleeding time, it also significantly decreased the clotting time, fibrinogen level andplatelets counts.

CONCLUSION: This study therefore shows that Piroxicam impairs hemostasis while Vitamin E administrationfurther enhances the activities of Piroxicam on hemostatic parameters.
