Brief Summary
-----------------
This is a clinical study that aims to investigate and compare the efficacy of transbuccal paracetamol 125 mg with that of paracetamol 1g administered intravenously in patients with acute pain of moderate intensity accepted to emergency room following a minor trauma of the lower limbs and/or superiors.
