Administering a magnesium lozenge 30 minutes before surgery appears to reduce the incidence and severity of immediate postoperative sore throat (POST), according to a small analysis of patients undergoing orthopedic surgery. The incidence rate for POST was 23% among those who received the lozenge, compared with 57% for controls, in the second hour after surgery.
