Comparison of intramuscular and oral meloxicam in rheumatoid arthritis patients.

OBJECTIVE: This double-blind, double-dummy, two-way comparative trial evaluated the overall efficacy and tolerability of intramuscular (im) vs oral meloxicam. SUBJECTS: 346 patients with rheumatoid arthritis (RA). TREATMENT AND METHODS: 173 patients in each group were randomised to receive either im meloxicam (15 mg) plus a placebo tablet, or oral meloxicam (15 mg) plus a placebo injection for 7 days. RESULTS: Significant (p < 0.001) improvements in overall pain and disease activity were observed by patients treated with im and oral meloxicam, with no significant difference between treatments. The im formulation was better than the oral tablet in terms of rapidity of action (p=0.012), global efficacy (p=0.030) and duration of morning stiffness (p=0.026). Local tolerability of im meloxicam was very good and comparable with placebo injections. CONCLUSION: Oral and im meloxicam (15 mg) were both effective and well-tolerated for acute exacerbations of RA. The im formulation had some advantages, such as a faster onset of action.

Electrolyte vs. glucose-electrolyte isotonic solutions for oral rehydration therapy in horses.

An isotonic electrolyte solution with a composition similar to equine sweat was compared to an isotonic glucose-glycine-electrolyte solution for oral rehydration therapy in exercising horses. Ten horses were dehydrated by using frusemide and allocated randomly to receive 4 different oral solutions: isotonic sweat-like electrolyte solution, half-strength hypotonic electrolyte solution, isotonic glucose-glycine-electrolyte solution, and plain water. Solutions were given by nasogastric tube using the same volume as the bodyweight lost by each horse. Blood samples were collected before and throughout 6 h of the rehydration period. Results showed that all solutions recovered pre-frusemide values of packed cell volume (PCV) and total plasma protein (TP) in a similar fashion. No changes for Na+ values were observed during the rehydration period when the isotonic sweat-like solution was used. However, a significant hyponatraemia was induced throughout rehydration when the other 3 solutions were given, especially when hypotonic solution and water were used. Osmolality values did not change when both isotonic solutions were administered; but a significant hypotonicity was observed when hypotonic solution and water were given. When the isotonic sweat-like solution was used, plasma Cl-, K+ and creatinine values recovered to premedication values significantly faster than the other 3 solutions. In conclusion, the isotonic sweat-like electrolyte was the best solution because it restored rapidly the fluid and plasma electrolyte imbalances. In contrast, the isotonic glucose-glycine-electrolyte solution impaired the plasma electrolyte imbalances.
