The question in the case revolves around the issue of the source of data that the agency relied on to approve the generic version of the drug.
RESULTS: Eighty-one patients participated in the study; 70 86.4% ; were females, and 11 13.6% ; were males. Patient demographic and clinical data at the initiation of the study are shown in Table 1. Forty-one patients were treated with diclofenac-cholestyramine and 40 with celecoxib. There were no statistically significant differences in basal values between these two groups. Five patients were withdrawn from the study due to side effects: 3 in the diclofenac-cholestyramine group and 2 in the celecoxib group. After 6 weeks of treatment, both, diclofenaccholestyramine and celecoxib induced a significant reduction in VAS scores Table 2 ; . When the patient carried out the evaluation, the median reductions in VAS score were 33% and 29.3% by diclofenac-cholestyramine and celecoxib, respectively. When the clinical investigator carried out the evaluation, median VAS score reductions were 41.7% and 36.8% by diclofenac-cholestyramine and celecoxib, respectively. Differences between treatments did not reach statistical significance. Both, diclofenaccholestyramine and celecoxib produced a variety of side effects. Of the patients treated with diclofenaccholestyramine, three were withdrawn before completion of the 6-week period, two due to headache and one due to rash. Two patients were withdrawn in the celecoxib group, one due to headache and one due to rash. The reported side effects, as well as their incidence, are given in and cleocin.

Al, 1996 ; . However, at the same time these patients are likely to be old and obese, which reduces compliance and are unable to participate in exercise programs. Therefore, tackling obesity by means of dietary manipulation and exercise remains a difficult option and not many obese patients are able to adopt and sustain the changes required in their lifestyle UK Prospective Diabetes Study Group, 1995 ; .Smoking has been associated with insulin resistance Law et al, 1992 ; and the result of a nonrandomized prospective study of healthy middle aged American men shows that cigarette smoking may be an independent risk factor for non-insulin dependent diabetes Rimm et al, 1995 ; . Unlike adverse effects of smoking on the development of NIDDM, moderate alcohol consumption seems to have beneficial effects, as it was found to be associated with a reduced risk of developing diabetes, possibly reflecting positive effects on insulin sensitivity . Many specific oral anti-diabetic agents have appeared in recent reviews on the treatment of NIDDM Leboviz; Groop, 1992 ; .

Fered significantly between the two treatments, with a decrease from baseline of 0.3 cm during the SAMe phase and an increase from baseline of 0.2 cm during the celecoxib phase. While this statistical difference does not seem to have much clinical meaning, future studies on the mechanism of action of SAMe might shed light on this decrease in knee circumference. Perceived physical fitness, emotional well-being and daily activities did not improve from baseline with either treatment. Fitness and well-being as well as daily activities might represent more stable attributes than physical complaints and thus might not change in a 2-months treatment.

But he dismissed as lame another of the berkeley group's assertions: that pot has currently accepted medical uses in the united states - a key requirement for reassignment to schedule ii and colchicine.
Cyclooxygense-2 COX-2 ; , has led to the synthesis and introduction of novel drugs with selective inhibitory effect on COX-2, the isoform produced in pathologic conditions cleecoxib in 1997 and rofecoxib in 1999 ; . This study was carried out to design and synthesize two novel celdcoxib derivatives with potential selective COX-2 inhibitory activity. Method: The derivatives were designed according to the Structure-Activity Relationship SAR ; data of selective COX-2 inhibitors. The condensation reaction of 4-hydrazinobenzoic acid and 4, 4-triflouro-1-ptolylbutane-1, led to the formation of 4- 5-p-tolyl-3- trifluoromethyl ; -1H-pyrazol-1-yl ; benzoic acid [8]. The carboxyl group of this acid was reduced to hydroxyl and then converted to chloride by freshly distilled thyonyl chloride. Successive reaction of chloride derivative with sodium sulfite, phosphrous pentachloride and ammonia led to the formation of sulfonamide derivative and reaction of it with sodium azide led to the azide analogue. Results: About 4 grams of each derivative has been synthesized total yield 60-70% ; and their chemical structures have been verified using appropriate spectroscopic methods. Conclusion: In this study, two novel cleecoxib analogues with a methylene bridge distance between sulfonamide and azide functional groups and the rest of the molecule were designed and synthesized according to the SAR data of selective COX-2 inhibitors. This methylene group brings the pharmacophoric sulfonamide and azide functional groups closer to the binding site and leads to better binding. Furthermore, this methylene group provides free rotation to pharmacophore to attain appropriate conformation for better binding. Hopefully, pharmacological evaluation of derivatives, which is currently in progress, will confirm these assumptions.

Similarly, inactivation of PPAR influences the transcription of genes involved in cell proliferation and apoptosis 4, 5 ; . Several lines of evidence suggest a possible coordinated action and cross-talk between the two molecules 6, see below ; . In human breast cancer, independent studies demonstrate that COX-2 and PPAR , respectively, exhibit induction 710 ; and inactivation 10, 11 ; . Experimental evidence suggests that inhibition of COX-2 1214 ; , e.g., by celecoxib, and activation of PPAR 1517 ; , e.g., by glitazones or 12, 14 -PGJ2 15d-PGJ2 ; , prevent carcinogen-induced mam15-deoxymary cancer in animals. Recently, combinational targeting of more than one molecule, e.g., estrogen receptors and PPAR 15 ; or retinoid X receptors and PPAR 16 ; , has emerged as an approach that provides more effective prevention with fewer side effects than targeting separate molecules. We thought, therefore, that simultaneous targeting of COX-2 and PPAR might act additively, if not synergistically, to inhibit the development of mammary cancer. Although several mechanisms are proposed to explain the antitumorigenic action of COX-2 inhibitors and PPAR ligands in the mammary gland, their effect on apoptotic signaling and cell proliferation has received particular attention 6 ; . Available information suggests that tissue growth depends upon the balance between cell growth and death. The two rates are normally balanced in the adult resting normal mammary gland so that overgrowth does not occur 18 ; . Apoptosis plays a critical role in the homeostasis of the mammary glands, e.g., in tissue remodeling during postlactation involution 19 ; . A major pathway implicated in apoptosis in the normal and cancerous ; mammary gland is the intrinsic or mitochondrial signaling triggered and mediated by Bcl2 family members, e.g., BAX and Bcl2 19, 20 ; . The antiapoptotic Bcl2 is detected in 80% of breast cancer cases and is related to metastasis, chemoresistance, and poor prognosis 19 ; . The proapoptotic BAX, on the other hand, is expressed in high levels in the normal breast tissue but only weakly or not at all in tumor 21 ; . Loss of BAX correlates with shorter survival time and faster tumor growth 22, 23 ; . The interaction between BAX and Bcl2 determines the net apoptotic gains and can subsequently play a critical role in cancer development and prevention 19, 24, 25 ; . Many cancer therapeutic 26 28 ; and preventive 24, 29 ; agents mediate their action by altering the activity and expression of Bcl2-family genes proteins. Similarly, COX-2 inhibitors and PPAR ligands induce proapoptotic signaling in human breast cancer cells by up-regulating BAX and down-regulating Bcl2 30 32 ; transcription. Several antiapoptotic factors, e.g., protein kinase C PKC ; , influence BAX-Bcl2 interaction and, thereby, mediate cell survival 33 ; . Another mechanism by which COX-2 inhibitors and PPAR ligands may inhibit carcinogenesis is by attenuating cell growth and inducing cell cycle arrest 6, 32 ; . This action may occur because of the ability of these agents to reduce the expression of markers of cell proliferation, e.g., proliferating cell nuclear antigen PCNA; Refs. 34, 35 ; and Ki-67 36, 37 ; , and deregulate the activity of factors involved in cell cycle progression, e.g., cyclin-dependent kinases cdks; Ref. 38 ; . Accordingly, during mammary carcinogenesis, the extent to which COX-2 inhibitors and PPAR ligands influence the dynamic interaction between apoptosis and cell proliferation may play a role in their cancer preventive efficacy. In this report, we examine the efficacy of celecoxib, a COX-2 and fluoxetine.
