In April 2014, sodium-glucose cotransporter 2 inhibitor (SGLT-2i) was introduced in Japan. In May 2015, the prescription limitation for SGLT-2i was lifted. Subsequently, SGLT-2i was shown to reduce cardiovascular events in patients with type 2 diabetes mellitus (T2DM). SGLT-2i prescription is expected to increase and consequently affect the prescription trends for other antidiabetic agents. Therefore, we evaluated the trends for antidiabetic agent prescriptions in Japan from April 2012 to March 2020. In this study, a dynamic cohort consisting of patients with T2DM derived from the Japan Medical Data Center health insurance database and with at least one antidiabetic agent prescription was investigated. The prescription rates were calculated monthly (/1000 person-months) for each class of antidiabetic agent. The eligible cohort comprised 34333 patients. The prescription rate for dipeptidyl peptidase-4 inhibitor increased from 424.0 in April 2012 to 656.3 in May 2015, and slightly decreased to 635.4 in March 2020. The prescription rate for biguanide consistently increased from 347.2 in April 2012 to 500.1 in March 2020. The prescription rate for sulfonylurea consistently decreased from 393.8 in April 2012 to 172.5 in March 2020. The prescription rate for SGLT-2i consistently increased from 4.1 in April 2014 to 363.1 in March 2020. SGLT-2i prescription increased and may affect the prescription trends for dipeptidyl peptidase-4 inhibitor and sulfonylurea after May 2015, when the prescription limitation for SGLT-2i was lifted. Biguanide prescriptions increased regardless of the introduction of SGLT-2i. The treatment of T2DM in Japan is clearly changing, with a focus on SGLT-2i and biguanide.

Background It has been reported that bepridil is as good as amiodarone in converting persistent atrial fibrillation (AF) to sinus rhythm (SR). The conversion effect of bepridil alone is not always satisfactory, however. The efficacy of pharmacological cardioversion by the combination of bepridil and a class Ic antiarrhythmic drug for persistent AF is studied. Methods and Results The participants comprised 37 consecutive patients in whom pharmacological cardioversion was conducted to treat persistent AF (duration 22.5±29.6 months). Each patient first received a class Ia or Ic antiarrhythmic drug, then bepridil alone, then a combined therapy of bepridil at 200 mg/day with a class Ic antiarrhythmic drug at a routine dose. Unaccompanied use of any of the antiarrhythmic drugs achieved pharmacological cardioversion in 14 (38%) of the 37 patients (single therapy group), whereas SR was restored by combination of bepridil and a class Ic antiarrhythmic drug in 22 (combined therapy group) of the remaining 23 patients. The duration of AF was significantly longer in the combined therapy group than in the single therapy group (28.3±31.0 vs 7.3±4.1 months). Conclusion Combined therapy of bepridil and a class Ic antiarrhythmic drug is efficient for pharmacological cardioversion of refractory long-lasting persistent AF. (Circ J 2008; 72: 709 - 715)
