| Abstract | BACKGROUND: Dapagliflozin, a selective inhibitor of renal sodium glucose co-transporter 2, is under development for the treatment of type 2 diabetes mellitus. Dapagliflozin elimination is primarily via glucuronidation to an inactive metabolite, dapagliflozin 3-O-glucuronide. Pharmacokinetic studies are recommended in subjects with impaired hepatic function if hepatic metabolism accounts for a substantial portion of the absorbed drug. OBJECTIVE: The purpose of our study was to compare the pharmacokinetics of dapagliflozin in patients with mild, moderate, or severe hepatic impairment (HI) with healthy subjects. METHODS: This was an open-label, parallel-group study in male or female patients with mild, moderate, or severe HI (6 per group according to Child-Pugh classification) and in 6 healthy control subjects. The control subjects were matched to the combined HI group for age (±10 years), weight (±20%), sex, and smoking status, with no deviations from normal in medical history, physical examination, ECG, or laboratory determinations. All participants received a single 10-mg oral dose of dapagliflozin, and the pharmacokinetics of dapagliflozin and dapagliflozin 3-O-glucuronide were characterized. Dapagliflozin tolerability was also assessed throughout the study. RESULTS: Demographic characteristics and baseline physical measurements (weight, height, and body mass index) were similar among the 18 patients in the HI groups (58-126 kg; 151.2-190.0 cm, and 31.5-37.7 kg/m(2), respectively) and the healthy subject group (65.0-102.6 kg; 166.0-184.0 cm, and 23.3-34.3 kg/m(2), respectively). In those with mild, moderate, or severe HI, dapagliflozin mean C(max) values were 12% lower and 12% and 40% higher than healthy subjects, respectively. Mean dapagliflozin AUC(0-∞) values were 3%, 36%, and 67% higher compared with healthy subjects, respectively. Dapagliflozin 3-O-glucuronide mean C(max) values were 4% and 58% higher and 14% lower in those with mild, moderate, or severe HI compared with healthy subjects, respectively, and mean dapagliflozin 3-O-glucuronide AUC(0-∞) values were 6%, 100%, and 30% higher compared with healthy subjects, respectively. These values were highly dependent on the calculated creatinine clearance of each group. All adverse events were mild or moderate, with no imbalance in frequency between groups. CONCLUSIONS: Compared with healthy subjects, systemic exposure to dapagliflozin in subjects with HI was correlated with the degree of HI. Single 10-mg doses of dapagliflozin were generally well tolerated by participants in this study. Due to the higher dapagliflozin exposures in patients with severe HI, the benefit:risk ratio should be individually assessed because the long-term safety profile and efficacy of dapagliflozin have not been specifically studied in this population. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
