Abstract
Aim: The present study aimed to prepare and evaluate fexofenadine self-microemulsifying drug-delivery systems (SMEDDS) formulation and to determine and compare its intestinal permeability using in situ single-pass intestinal perfusion (SPIP) technique.Methods: Fexofenadine-loaded SMEDDS were prepared and optimized. Droplet size, polydispersity index, zeta potential, drug release and intestinal permeability were evaluated.Results: Optimized formulation consisted of 15% oil, 80% surfactant and 5% cosolvent. Droplet size and drug loading of optimized formulation was 13.77 nm and 60 mg/g and it has released 90% of its drug content. Intestinal permeability of fexofenadine was threefold enhanced in SMEDDS compared with free fexofenadine.Conclusion: The results of our study revealed that SMEDDS could be a promising tool for oral delivery of fexofenadine with enhanced dissolution rate and intestinal permeability.
期刊介绍：
Delivering therapeutics in a way that is right for the patient - safe, painless, reliable, targeted, efficient and cost effective - is the fundamental aim of scientists working in this area. Correspondingly, this evolving field has already yielded a diversity of delivery methods, including injectors, controlled release formulations, drug eluting implants and transdermal patches. Rapid technological advances and the desire to improve the efficacy and safety profile of existing medications by specific targeting to the site of action, combined with the drive to improve patient compliance, continue to fuel rapid research progress. Furthermore, the emergence of cell-based therapeutics and biopharmaceuticals such as proteins, peptides and nucleotides presents scientists with new and exciting challenges for the application of therapeutic delivery science and technology. Successful delivery strategies increasingly rely upon collaboration across a diversity of fields, including biology, chemistry, pharmacology, nanotechnology, physiology, materials science and engineering. Therapeutic Delivery recognizes the importance of this diverse research platform and encourages the publication of articles that reflect the highly interdisciplinary nature of the field. In a highly competitive industry, Therapeutic Delivery provides the busy researcher with a forum for the rapid publication of original research and critical reviews of all the latest relevant and significant developments, and focuses on how the technological, pharmacological, clinical and physiological aspects come together to successfully deliver modern therapeutics to patients. The journal delivers this essential information in concise, at-a-glance article formats that are readily accessible to the full spectrum of therapeutic delivery researchers.
