Background Several studies have shown the effectiveness of sitagliptin, a dipeptidyl peptidase-4 inhibitor, for type 2 diabetes, having a hypoglycemic effect being proven both when it is administered alone or in combination with additional oral antidiabetic agents. and body weight, were investigated retrospectively. Compliance with diet and exercise therapy at 48 weeks was checked by 873305-35-2 manufacture a questionnaire. Results In the 93 individuals analyzed (sitagliptin monotherapy, n = 9; combination therapy, n = 77; and switching from an alpha-glucosidase inhibitor or glinide, n = 7), hemoglobin A1c (HbA1c) showed a significant decrease after 24 weeks (7.70 0.73% at baseline vs. 6.90 0.55% at 24 weeks), but showed hook increase at 48 weeks after that. HbA1c was eventually preserved in the same range without significant adjustments until 72 weeks. An optimistic relationship was noted between your noticeable adjustments of HbA1c and bodyweight from 24 to 48 weeks. Conformity with diet and exercise therapy was worse in Rabbit polyclonal to ALX3 sufferers teaching a 0.3% increase of HbA1c (n = 37) from 24 to 48 weeks than in others (n = 56). Multiple logistic regression evaluation demonstrated that both elements were unbiased determinants from the boost of HbA1c from 24 weeks onward. Conclusions Sitagliptin showed great basic safety and efficiency when administered for 1 . 5 years as both monotherapy and mixture therapy. Inadequate conformity with diet plan/workout therapy and fat again could be associated with a rise of HbA1c as time passes during treatment with sitagliptin. Keywords: Sitagliptin, Type 2 diabetes, Hemoglobin A1c, Long-term administration Launch Sitagliptin is normally a dipeptidyl peptidase-4 inhibitor that’s used to take care of diabetes [1, 2], sufferers with type 2 diabetes and decreased incretin activity [3 specifically, 4]. When implemented alone, it does not have any potential to trigger fat or hypoglycemia gain. More than 24 months have transferred since this medication became available medically in Japan. Many scientific research over the efficiency of sitagliptin have been 873305-35-2 manufacture completely performed [5-10], and have clearly demonstrated that it exhibits a hypoglycemic effect when administered only or in combination with additional oral antidiabetic providers [11-15]. We are currently following 1,332 individuals on sitagliptin therapy in the ASSET-K study [11, 12]. We performed the present analysis because hemoglobin A1c (HbA1c) tended to increase again after 1 year of sitagliptin therapy in the ASSET-K study. The follow-up period was only several months in most of the earlier studies and was a maximum of 1 year actually in the medical studies performed for development of this drug. However, because treatment of type 2 diabetes has to be continued over very long periods, such as 10 years or more, long-term effectiveness and security have to be confirmed for the medicines used to treat this disease. Therefore, we carried out a retrospective analysis to investigate the long-term effectiveness and security of sitagliptin. We also targeted to clarify the reason behind deterioration of HbA1c by comparing individuals in whom HbA1c improved with those in whom a stable level was managed. Materials and Methods Patients Of the 375 individuals treated with sitagliptin (50 mg/day time) at Kanamori Internal Medicine Clinic between December 873305-35-2 manufacture 2009 and March 2012, 133 could be adopted up continually for 72 weeks. Among them, 40 individuals were excluded from the study because the dose or type of concomitant medications was changed during the follow-up period. Clinical indices, such as blood glucose, HbA1c, and excess weight, were investigated retrospectively in the 93 individuals who could be adopted up continually for 72 weeks without any switch in the dose of sitagliptin or the dosages or types of concomitant medications. Patient compliance with diet/exercise therapy was investigated at 48 weeks by using a questionnaire [16]. Honest considerations The present analysis was carried out as a part of the ASSET-K study. The ASSET-K protocol was devised in accordance with the Declaration of Helsinki and received honest approval from your institutional review table of the Kanagawa Physicians Association. This study was undertaken in accordance with the Ethical Recommendations for Clinical Studies of the Japanese Ministry of Health, Labor, and Welfare. Statistical analysis Results are given as the mean standard deviation. The profile of changes.
