Aims: Evogliptin is a potent and selective dipeptidyl peptidase‐4 inhibitor for glycaemic control in patients with type 2 diabetes mellitus. Since evogliptin is mainly eliminated through hepatic metabolism, we investigated the pharmacokinetics (PKs) and safety characteristics of evogliptin in Korean patients with mild or moderate hepatic impairment. Methods: An open‐label, parallel‐group study was conducted in patients with mild or moderate hepatic impairment and healthy control subjects matched to each patient for sex, age and body mass index. A single dose (5 mg) of evogliptin was administered orally, and serial blood samples were collected over 120 h to assess the PK profile of evogliptin and its main metabolites (M7 and M8). Results: Patients with mild hepatic impairment and their matched healthy controls showed similar maximum concentration (Cmax) and area under the concentration–time curve values from 0 to 120 h (AUClast); the geometric mean ratio (GMR) and 90% confidence interval (CI) were 1.04 (0.80, 1.35) and 1.01 (0.90, 1.14), respectively. Exposure to evogliptin (Cmax and AUClast) was increased by about 40% in patients with moderate hepatic impairment—the GMR and 90% CI were 1.37 (1.09, 1.72) and 1.44 (1.18, 1.75), respectively. The metabolic ratios of M7 and M8 were lower in patients with moderate hepatic impairment than in matched healthy controls. Evogliptin was well tolerated by both patients and healthy subjects. Conclusion: Although evogliptin exposure was increased in patients with moderate hepatic impairment, the increase is unlikely to affect safety and efficacy adversely, and no dose adjustment is warranted.

Background: Medication counseling is a critical component of pharmaceutical care to promote the safe and effective use of medications and to maximize therapeutic outcomes. The assessment of patients' and pharmacists' satisfaction with medication counseling services could be one of the vital parameters for predicting the quality of pharmacy services. No study has measured and compared both patients' and pharmacists' satisfaction with medication counseling. The objectives of this study were to describe and compare patients' and pharmacists' levels of satisfaction with medication counseling services offered by community pharmacists in South Korea.Methods: This was a descriptive, cross-sectional survey. The online survey was distributed to patients and community pharmacists using a structured questionnaire. The questionnaires consisted of 4 main areas: (1) responders' characteristics (2) current state of medication counseling methods provided by community pharmacies (3) overall satisfaction with medication counseling (4) demand for the development of medication counseling standards. A comparison between patients and pharmacists was made using either a chi-square test or a Fisher's exact test.Results: Between June 13, 2014 and July 15, 2014, a total of 252 patients and 620 pharmacists completed the survey. It was found that 47.3% of pharmacists and 34.0% of patients were satisfied with the current medication counseling service. Pharmacists showed a higher degree of satisfaction with the medication counseling service compared to patients (p <0.05). A major reason for patients not being satisfied with the medication counseling from community pharmacists was the insufficient time spent on counseling (51.2%). The pharmacists' perception of a major barrier to providing appropriate medication counseling for patients was the lack of time (24.3%). Moreover, a substantial number of patients (88%) and pharmacists (73%) supported the development of medication counseling standards to improve community pharmacist counseling services (p < 0.001).Conclusions: This study showed that both patients and pharmacists have low levels of satisfaction with the current medication counseling service offered by community pharmacists. This study provides baseline data for the development of national guidelines for medication counseling by pharmacists. [ABSTRACT FROM AUTHOR]
