        불안신경증과 알코올남용·의존 환자에서 Tofisopam의 항불안 및 항우울 효과 검증

        김승태(Seungtai. Peter Kim),홍경수(Kyung-Sue Hong),김도관(Doh Kwan Kim),홍성도(Sungdo David. Hong),유범희(Bum-Hee Yu) 한국중독정신의학회 1997 중독정신의학 Vol.1 No.1

        The study aims at evaluating antianxiety and antidepressant effects of tofisopam, a benzodiazepine-related chemical substance with some variations in its nitrogen number and positions. The study subjects were 27 adult outpatients, namely, 11 anxiety neurosis patients(M 6, F 5) and 16 alcohol abuse or alcohol dependence patients(M 13, F 3), diagnosed according to DSM-IV. Tofisopam, doses ranging 100-150mg per day, was administered to each patient in an open clinical trial, over a period of 6-8 week. Each patient was administered with Hamilton Anxiety Scale(HAS) and Hamilton Depression Scale(HDS) twice, before the initiation of tofisopam admininistration and at the completion of 6-8 weeks of the medication administration, to assess the degree and extent of improvements of anxiety and depression symptoms. The following results were obtained from the study: (1) Tofisopam showed noticeably significant antianxiety effects and less significant antidepressant effects. (2) There were no clinically observable or reported untoward CNS effects(e.g. drowsiness, impaired memory, disturbance in attention, etc.) by tofisopam. (3) The more significant improvements among the anxiety symptom clusters were physical(musculomotor and sensory) and autonomic nervous system symptoms. (4) During and immediately after the completion of 6-8 weeks of tofisopam adminstration, alcoholic patients reported of significantly reduced or extinct alcohol cravings. However, it remains to be carefully evaluated whether anticraving effects of tofisopam is transient, long lasting, or psychogenic, etc. The study results warrants further careful revalidations by use of a longitudinal double-blind crossover design and on a large number of patients.

        그란닥신 정(토피소팜 50mg)에 대한 토핌 정의 생물학적 동등성

        조혜영,정현철,허수희,임동구,문재동,이용복 한국약제학회 2001 Journal of Pharmaceutical Investigation Vol.31 No.2

        Tofisopam is a new type of tranquilizer valuable for the relief of anxiety and tension in a wide range of emotional disorders. Tofisopam has the therapeutic characteristics of a minor tranquilzer and a mild stimulatory effect. The purpose of the present study was to evaluate the bioequivalence of two tofisopam tablets, Grandaxin^TM (Hwan In Pharmaceutical Co., Ltd.) and Tofim^TM (Kyung Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, 23.11±2.83 years in age and 65.43±7.64 kg in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After one tablet containing 50 mg of tofisopam was orally administered, blood was taken at predetermined time intervals and the concentrations of tofisopam in serum were determined using HPLC method with UV detector. The pharmacokinetic parameters such as AUC_t C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t C_max and T_max between two tablets based on the Grandaxin^TM were -5.59%, 2.22% and -13.18%, respectively. Minimum detectable differences (Δ) at α=0.10 and 1-β=0.8 were less than 20% (e.g., 14.95% and 19.34% for AUC_t and C_max respectively). The powers (1-β) at α=0.10, Δ=0.2 for AUC_t and C_max were 95.21% and 81.93%, respectively. The 90% confidence intervals were within ±20% (e.g., -15.64∼4.45 and -10.77∼15.21 for AUC_t and C_max respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Tofim^TM tablet is bioequivalent to Grandaxin^TM tablet.
