| Abstract | BACKGROUND: A zolpidem sublingual tablet (ZST) formulation was recently approved by the US Food and Drug Administration to treat middle-of-the-night (MOTN) awakening with difficulty returning to sleep. OBJECTIVE: The aim of this study was to compare the zolpidem pharmacokinetic profiles of 3.5-mg ZST and 10-mg immediate-release (IR) oral zolpidem in healthy female and male adults. METHODS: This randomized, open-label crossover study compared the pharmacokinetic profile of ZST with that of IR oral zolpidem in healthy adults. RESULTS: The study enrolled 19 males and 14 females. After 3.5-mg ZST and 10-mg IR, respectively, mean zolpidem plasma concentrations at 15 minutes (22 vs 17 ng/mL, respectively, in females and 18 vs 10 ng/mL in males) and AUCs from zero to 15 minutes (2.3 vs 0.8 ng · h/mL in females and 1.6 vs 0.5 ng · h/mL in males) were substantially greater for ZST, despite the larger absolute IR dose. After 3.5-mg ZST and 10-mg IR, respectively, clearance was lower in females, even after correcting for body weight (2.63 vs 2.88 mL/min/kg in females and 3.63 vs 3.91 mL/min/kg in males). The lag time prior to the start of first-order absorption was notably shorter for ZST than IR in both males (8 vs 21 minutes) and females (5 vs 22 minutes). Both zolpidem formulations were generally well tolerated by both genders. CONCLUSIONS: Systemic exposure of zolpidem was higher in females for both formulations. Plasma levels and AUC were higher, and clearance was lower, in females with both zolpidem formulations. The initial rate of absorption was faster, and initial systemic exposure was greater, with ZST compared with oral IR. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
