Prostaglandins (PGs) and aluminum-containing antacids (Al.AAs) are effective in preventing gastric and duodenal lesions induced by neutralizing agents. The efficacy of Al.AAs is thought to be due to neutralizing properties and to stimulation of endogenous PGs synthesis. Liquid Maalox has the same effect as cimetidine 400 mg on postprandial duodenal acid load. In numerous prospective studies, Al.AAs have been shown to be as effective as cimetidine in the short-term treatment of duodenal ulcer (DU). Maalox TC at a dosage of 3 tablets b.i.d. provides an effective method for preventing DU relapse. Its effect is similar to that of nighttime cimetidine. Meta-analysis of prospective trials suggests that Al.AAs prevent stress ulcers more effectively than does cimetidine. It has been suggested that Al.AA acts by inducing surface epithelial cell disruption. Al-induced mucosal protection could be caused by a stimulated release of endogenous PGs, induced by Al microcrystal penetration of cells. In a recent study, we showed that small amounts of Al were absorbed by human gastric mucosa and accumulated in lysosomes; however, we did not observe any histological or ultrastructural lesions of the gastric mucosa. Prostaglandins (enprostil, misoprostol, and rioprostil) are as effective as cimetidine, but less effective than ranitidine, in healing DU. Enprostil and rioprostil have been shown to be as effective as ranitidine in treating gastric ulcer (GU). Moreover, enprostil inhibits postprandial gastrin release, whereas H2-blockers increase gastrin levels. Coadministration of misoprostol with aspirin is highly effective in healing aspirin-induced gastroduodenal lesions. Moreover, cotreatment with misoprostol was associated with a marked decrease in GU in patients with osteoarthritis receiving NSAIDs chronically.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of oral administration of the anti-inflammatory drug, (Z)-5-fluoro-2-methyl-1-[p-(methylsulfinyl)-benzylidene]-indene-3-acetic acid (sulindac, Clinoril) 400 mg/d for 8 days, on basal and submaximal (3 micrograms/kg b.2. i.m.) and maximal (6 micrograms/kg b.w.) pentagastrin-stimulated gastric acid secretion as well as on serum gastrin concentration have been evaluated in female patients affected with osteoarthrosis. No significant changes in either gastric acid or gastrin secretion were induced by the treatment. Serum gastrin levels were also unaltered after acute administration of 200 mg sulindac. These results confirm and extend previous observations suggesting that the drug does not exert major actions on the stomach.

Several experimental studies in the animal models and the use of calcitonin in patients with osteoarthritis, rheumatoid arthritis, and osteoporosis have shown multiple actions of this hormone, justifying its use in the wide range of osteoarthritic pathologies. We used well known animal models of tests to study chondro-tropic drugs such as: post-corticoid arthropathy, partial meniscectomy, immobilization of the lower extremity of rabbits, follow-up of the natural knee degeneration in the black mouse C57, and radiolabelled sulphates uptake by the cartilage, and have shown: (a) anticatabolic effect of salmon calcitonin as measured as GAG levels, width of articular space, and histochemical and morphologic examination of the cartilage in some model arthropathies, (b) anti-osteoporotic properties counteracting an effect of corticosteroids, (c) increased uptake of sulphates by the articular cartilage of the rat following calcitonin administration in vivo. The studies explaining mechanisms of calcitonin actions included IGF-1 assays and beta-endorphins. The former increased transiently after calcitonin administration whereas the latter increased after non-steroid anti-inflammatory agents use. Calcitonin decreased gastrin secretion with negligible effect on calcium ions and prostaglandin E2 levels in blood plasma while it potently acid secretion and increasing gastric mucus content in the stomach. The use of calcitonin in patients with arthrosis, rheumatoid arthritis, and osteoporosis with accompanying peptic and/or duodenal ulcers produced healing of peptic and/or duodenal ulcers in 75% of patients within 4 weeks with simultaneous shortening of the morning stiffness, increase in hand grip strength (in rheumatoid arthritis), and significant decrease in pain as well as an improvement in the quality of life in the majority of the treated patients.(ABSTRACT TRUNCATED AT 250 WORDS)
