The effect of diclofenac sodium on urinary concentration of calcium, uric acid and glycosaminoglycans in traumatic paraplegics.
Non-steroidal anti-inflammatory drugs (NSAID) have been shown to decrease calcium excretion in the experimental animal, in human volunteers and in calcium stone formers. Paraplegics tend to be hypercalciuric during the first 2 years after their injury and this is said to be a predisposing factor for stone formation in these patients. The effect of the NSAID diclofenac sodium was studied in 12 traumatic paraplegics who had sustained their injury 1 to 6 months previously; 24-h urine samples collected before and 2 weeks and 4 weeks after oral diclofenac sodium 50 mg tds were analysed for calcium, uric acid, glycosaminoglycans (GAGs) and volume. There were no significant changes in urinary volume, uric acid and GAGs excretion. However, urinary calcium concentration and 24-h calcium excretion decreased significantly following 2 weeks' and 4 weeks' treatment with diclofenac sodium.
