| Abstract | AIM: This study investigated the pharmacokinetics of prucalopride in Chinese healthy volunteers. METHODS: This single-center, open-label study was conducted in 14 healthy males and 14 healthy females, aged 18 - 45 years. Fasted subjects received a single dose of 2 mg prucalopride, and after a 7-day wash-out period, they received the same dose once-daily for 7 days at fasted condition. Serial blood samples were taken at predefined time-points to measure plasma concentrations of prucalopride during the single-dose and multi-dose period. Daily evaluations were made on defecation frequency and stool consistency. Safety assessments were performed throughout the study. RESULTS: After oral administration, prucalopride reached the peak plasma level (Cmax) of 4.92 ± 0.78 ng/ml with a median time to Cmax (tmax) of 2 hours and resulted in an area under concentration-time curve (AUC0-∞) of 89.3 ± 15.82 h×ng/ml. Steady state was attained 3 days after repeated dosing, when Cmax was 8.09 ± 1.21 ng/ml and AUC0-24h was 103.6 ± 14.35 h×ng/ml. Pharmacokinetic profiles were similar between genders except males had a slightly lower exposure level. Marked increase of defecation frequencies and predominance of 'watery' or 'loose' stools were seen after a single dose. The responses during multi-dose period were less remarkable and returned to baseline in 3 days. CONCLUSION: The pharmacokinetics of prucalopride 2 mg oral dose in Chinese healthy volunteers are similar to those observed in Caucasians. Compared to females, males exhibited a slightly lower exposure of prucalopride but similar changes of bowel habits were observed in both genders suggesting the inter-gender pharmacokinetic differences are not clinically relevant. |

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.
