Sodium fluoride treatment is a major protector against vertebral and nonvertebral fractures when compared with other common treatments of osteoporosis: a longitudinal, observational study.

In a 5-year observational study we have compared sodium fluoride (NaF) with different treatments commonly used in the treatment of osteoporosis: calcium, estrogens, androgens, and calcitonin, referred to as non-NaF. We have looked at the incidence of vertebral and nonvertebral fractures. At baseline, the NaF group, consisting of 125 patients (89% females) aged 65 +/- 10 (X +/- SE) had more crush fractures (P < 0.0001) and more months since menopause (P = 0.004) than the non-NaF group, consisting of 127 patients (90% females) aged 63 +/- 10. Fractures were evaluated by X-ray. The entire follow-up of patients treated with NaF accounted for 361 person-years, of whom 43 patients suffered one or more new vertebral fractures (68 vertebral fractures in total) and 18 patients suffered one or more new nonvertebral fractures (22 complete peripheral fractures in total); follow-up of patients treated with non-NaF regimes accounted for 382 person-years, of whom 53 patients suffered one or more new vertebral fractures (69 vertebral fractures in total) and 20 patients suffered one or more new nonvertebral fractures (27 complete peripheral fractures in total). After adjusting for significant covariates at baseline, NaF proved to be a significant protector for vertebral fractures [odds ratio (OR) 0.48, 95% confidence interval (CI) 0.2-0.9], and for peripheral fractures (QR 0.41, 95% CI 0.2-0.9). On the other hand, the probability of suffering undesired effects was much higher with NaF treatment (OR 5.04, 95% CI 2.1-11.9). We conclude that in the treatment of osteoporosis, NaF has a protective effect against vertebral and nonvertebral fractures, does not increase the risk of femoral fractures, but has a higher incidence of untoward symptomatology.

Multicenter clinical trial of zinc acexamate in the prevention of nonsteroidal antiinflammatory drug induced gastroenteropathy. Spanish Study Group on NSAID Induced Gastroenteropathy Prevention.

OBJECTIVE: To assess in a multicenter double blind clinical trial the gastroenteroprotective effect of zinc acexamate (ZAC). METHODS: 276 patients with rheumatic disease and history of peptic ulcer or intolerance to nonsteroidal antiinflammatory drugs (NSAID), and requiring treatment with these drugs were included. An initial normal endoscopy was needed for inclusion. Patients were treated with one NSAID (diclofenac, piroxicam, naproxen or ketoprofen) and one capsule (300 mg) of either ZAC (141 patients) or placebo (135 patients) at single nocturnal dose. After 28 days, patients underwent a clinical and endoscopic control. RESULTS: 26 patients withdrew from the trial (10 of ZAC and 16 of placebo) and 41 were lost to followup (22 of ZAC and 19 of placebo). Gastroduodenal mucosal damage was graded according to a modified Lanza score. The incidence of gastric ulcer was null with ZAC and 6.0% with placebo (6 cases) (p < 0.05). The incidence of duodenal ulcer was 0.9% with ZAC (1 case) and 6.0% with placebo (12 cases) (p < 0.001). Nine patients of ZAC group (8%) and 25 of placebo (25%) presented some gastric damage (p < 0.001), and 5 (5%) and 19 (19%) respectively presented some duodenal damage (p < 0.005). After treatment, 88% of patients treated with ZAC and 66% with placebo had a completely normal endoscopy (p < 0.0005). No major side effects were reported through the study. CONCLUSION: ZAC has shown to be effective and well tolerated for the prevention of NSAID induced gastroduodenal damage in patients with rheumatic disease at risk. The incidence of gastric and duodenal ulcers decreased in 92% (13 times the risk), when compared to placebo.

Droxicam: a pharmacological and clinical review of a new NSAID.

Droxicam acts by inhibition of PGE2 varies. Although it belongs to the oxicam family, it is characterised by being a pro-drug of piroxicam, the molecule undergoing conversion by hydrolysis once dissolved in the digestive tract. This allows us to suppose in principle that, there being less contact between the active drug (piroxicam) and the gastric mucosa, the side effects in the said mucosa would be slight. The studies which have already been performed in healthy volunteers and in patients with osteoarthritis and rheumatoid arthritis, to evaluate the efficacy and the tolerance of droxicam in patients suffering from such clearly inflammatory processes demonstrate an analgesic potential and anti-inflammatory effects which become noticeable after two weeks of treatment, and the drug is well-tolerated.
