Abstract
Background: Formononetin (FNT), a methoxy isoflavone, is a potential phytoconstituent utilized for refurbishing fractures in bone tissue. Conceding to its involvement in first-pass metabolism followed by glucuronidation, its absorption efficacy is limited. Hence, it belongs to the BCS class II classification.
Objective: We designed the present work to enhance FNT oral bioavailability by using Phospholipids (PL) as a promising carrier. Formononetin Phospholipid Complex (FNT-PC) was prepared by the solvent evaporation method and characterized.
Methods: FNT-PC was prepared by solvent evaporation method and characterization (FNT-PC) was performed using aqueous/n-octanol solubility and partition coefficient, FTIR, NMR, SEM, and in vivo pharmacokinetic study in female SD rats at 50 mg/kg.
Results: Physicochemical properties like aqueous/n-octanol solubility and partition coefficient were enhanced in FNT-PC. The FTIR spectrum confirmed there was no involvement of functional groups in the preparation of FNT-PC. Whereas, the NMR study resulted in the attachment of carbon (C-8) position of FNT by replacing the quaternary amine of PL to form FNT-PC. When scrutinized for its surface morphology, the FNT-PC exhibited the amorphous geometry that remarkably enhanced the dissolution of FNT (p<0.05) from its pure form. This dissolution effect was also affirmed by the per-oral administration of FNT-PC in female Sprague Dawley (SD) rats at 50 mg/kg dose. The pharmacokinetic profile showed the free FNT levels were markedly increased, correspondingly decreasing the conjugated FNT levels in rat plasma.
Conclusion: To summarize, FNT-PC could substantially reduce the first-pass metabolism with enhanced free concentration, improving oral bioavailability for therapeutic use.
期刊介绍：
Current Drug Delivery aims to publish peer-reviewed articles, research articles, short and in-depth reviews, and drug clinical trials studies in the rapidly developing field of drug delivery. Modern drug research aims to build delivery properties of a drug at the design phase, however in many cases this idea cannot be met and the development of delivery systems becomes as important as the development of the drugs themselves.
The journal aims to cover the latest outstanding developments in drug and vaccine delivery employing physical, physico-chemical and chemical methods. The drugs include a wide range of bioactive compounds from simple pharmaceuticals to peptides, proteins, nucleotides, nucleosides and sugars. The journal will also report progress in the fields of transport routes and mechanisms including efflux proteins and multi-drug resistance.
The journal is essential for all pharmaceutical scientists involved in drug design, development and delivery.
