    Abstract:
    AIM: to know the effect of piroxicam (COX-1 and COX-2 inhibitor NSAID) and meloxicam (selective COX-2 inhibitor NSAID) against the gastric mucosa. METHODS: a random, double-blind-parallel study and repeat measurement against 20 elderly-patients with knee-OA was conducted. Patients were divided into 2 equal groups, every group got piroxicam 20 mg/day or meloxicam 15 mg/day for 3 weeks. On the second group, sukralfat 2 x 1 g/day were given. To examine the difference before and after treatment, we used Wilcoxon signed rank test, to examine the difference within those groups we used Mann-whitney U test, to examine the correlation between endoscopic score and dyspepsia, we used the Spearman correlation test with significant correlation interpretation by Guilford rules. RESULTS: one of piroxicam group was resigned, so that there was 19 person left to complete this study. Piroxicam has caused elevation of endoscopic score in 78% subject compared to the beginning of study, and 22% of the subject has developed ulcers. Alteration of endoscopic feature after administration of this piroxicam was statistically significant (p< 0,05). Mild dyspepsia symptoms after piroxicam administration were positive on 67% subjects (p< 0,05). After administration of meloxicam, 40% subjects have elevated endoscopic score compared to beginning of the study (p< 0,05). Mild dyspepsia symptoms after meloxicam administration were positive on 40% subjects (p> 0,05). Meloxicam has less elevation of endoscopic score compared to the piroxicam (p< 0,05). By statistics, both of groups showed no difference in dyspepsia symptoms (p> 0,05). There was no significant correlation between elevation of endoscopic score and dyspepsia on both of groups. Nevertheless, it tends to have weak positive correlation (piroxicam group r= 0,306, p> 0,05, meloxicam group r= 0,330, p> 0,05). CONCLUSION: on this study, we conclude that the administration of either piroxicam or meloxicam in elderly-patient with knee-OA has caused the gastric mucosa impairment. The impairment after meloxicam administration is milder than piroxicam. There is no significant difference of dyspepsia symptoms in both of groups. There is correlation between endoscopic gastric mucosa features with the dyspepsia symptoms.
