[The analgesic effect of iontophoresis with magnesium sulfate].
The analgesic effect of iontophoresis with magnesium sulfate was studied in fourteen healthy adult volunteers. Magnesium sulfate 0.5 mg.5 ml-1 was locally administered by the iontophoresis with 1.0 mA electric current for 10 min. The pain recognition time was measured by the pain thermometer before and after 5, 15, 30, 60 and 120 min of iontophoresis. The pain recognition time was significantly extended and lasted for 60 min. These results support the view that the iontophoresis with magnesium sulfate has analgesic effect and produces a good pain relief clinically.
