چکیده انگلیسی
Owing to limited solubility, vitamin K undergoes low bioavailability with large inter-individual variability after oral administration. This article aimed to prepare self-nanoemulsifying lyophilized tablets (SNELTs) for the flash oral transmucosal delivery of vitamin K. Twenty-one formulae of vitamin K self-nanoemulsifying drug delivery systems (SNEDDS) were prepared using different concentrations of vitamin K, Labrasol, and Transcutol according to mixture design. The SNEDDS was loaded on porous carriers and formulated as lyophilized tablets. The release profile and the pharmacokinetic parameters of vitamin K SNELTs were evaluated in comparison with commercial tablets and ampoules on human volunteers. Results revealed that the optimized SNEDDS showed the smallest and most stable nanoemulsion globules. SNELTs were prepared successfully and showed substantial superiority drug release compared with the commercial tablets. Interestingly, SNELTs enhanced both rate and extent of vitamin K absorption as well as relative bioavailability (169.67%) in healthy subjects compared with the commercial tablets. SNELTs revealed promising no significant difference in the area under the curve compared with the commercial intramuscular injection. SNELTs enhanced dissolution and bioavailability that expected to have the strong impact on the efficiency of vitamin K in the prophylaxis and treatment of bleeding disorders in patients with hepatic dysfunction.
