[Evaluation of the analgesic activity of a soluble precursor of aspirin in orthopedic surgery].

We carried out a randomized double-blind trial to evaluate the analgesic effect, rapidity of action and tolerance of calcium carbasalate relative to a placebo, given in a single dose of 1 gr. aspirin equivalent immediately after an orthopedic surgical procedure. Autoevaluation by the patient using a visual scale and overall evaluation of analgesic effectiveness by the patient and relatives showed that pain was significantly less with the active therapy whose tolerance was excellent.
