Analysis of patients with hypoglycemia andor hyperglycemia induced by gatifloxacin Risk factors and patient profiles Toshiyuki Tamayama, Yasushi Tanaka and Atsushi Saito Drug Information Department, Kyorin Pharmaceutical Co., Ltd., 5 Kanda Surugadai, Chiyoda-ku, Tokyo, Japan Department of Medicine, Metabolism and Endocrinology, Juntendo University School of Medicine The Jikei University School of Medicine GATIFLO Tablets, containing gatifloxacingflx, a synthetic fluoroquinolone antibacterial agent, were launched in Japan in June. For several months after GFLX were marketed, cases of hypoglycemia andor hyperglycemia were reported as adverse drug reactions. Thus, Emergency Safety Information statement was issued in March, stipulating the contraindication of GFLX in patients with diabetes mellitus. Risk factors for inducing blood glucose change were estimated by analyzing data collected from 89 cases with severe blood glucose change reported by March. The results were as follows:. Of 89 cases, hypoglycemia was noted in 7589 and hyperglycemia in 5.7.. Patients with diabeties accounted for 5877.of hypoglycemia and 78.of hyperglycemia.. Patients 5 years or older accounted for 8 cases9.7of hypoglycemia and 7.of hyperglycemia.. Among cases with records on renal function, dysfunction was found in 989.of 55 cases of hypoglycemia, and 787.5out of 8 cases of hyperglycemia. Based on the above findings,diabetes mellitus,aged person,andrenal dysfunctionare estimated as major risk factors for blood glucose change induced by GFLX. To prevent adverse reactions related to blood glucose change, it is essential to recognize these risk factors and to administer GFLX appropriately based on statements in labeling on the package inserts.
