Geopolymers are a promising base for drug design as they allow for tuneable drug release and possess superior physical and chemical properties compared with conventional pharmaceutical excipients.<br /><strong>Methods:</strong> Geopolymer pellets containing zolpidem tartrate were administrated orally to beagle dogs as a controlled-release formulation with the commercial immediate-release product, Stilnoct^® tablets, as the control.<br /><strong>Results:</strong> The administration of zolpidem tartrate as immediate-release tablets demonstrated an elevated immediate release plasma profile and the zolpidem tartrate in the geopolymers demonstrated a controlled-release plasma profile. The pharmacokinetic analysis demonstrated that immediate-release tablet administration generated much higher plasma concentration when compared with geopolymer pellets administration for zolpidem tartrate. On the other hand, the geopolymer formulation prolonged the time of drug release.<br /><strong>Conclusion:</strong> Oral administration of zolpidem tartrate in geopolymer pellets demonstrated a controlled-release plasma profile.</p> Amina Vazda, Wei Xia, Håkan Engqvist Copyright (c) 2021 Amina Vazda, Wei Xia, Håkan Engqvist https://creativecommons.org/licenses/by-nc/4.0 https://sjms.sfulib10.publicknowledgeproject.org/scandjms/article/view/41 Tue, 19 Oct 2021 00:00:00 -0700 https://sjms.sfulib10.publicknowledgeproject.org/scandjms/article/view/883 Håkan Engqvist, Håvard Haugen Copyright (c) 2021 Håkan Engqvist, Håvard Haugen https://creativecommons.org/licenses/by-nc/4.0 https://sjms.sfulib10.publicknowledgeproject.org/scandjms/article/view/883 Tue, 23 Nov 2021 00:00:00 -0800
