Succinylated whey protein isolate as a sustained-release excipient of puerarin derivative oral tablets: Preparation, optimization and pharmacokinetics.

ABSTRACT: This work was done to investigate succinylated commercial whey protein isolate (S-WPI) as an oral sustained-release delivery carrier for puerarin 5 (PR-5). The succinylation conditions were established for S-WPIs by optimization of single factor study and Box-Beehnken design. The effect of succinylation degree on S-WPIs solubility was evaluated. Physicochemical properties of S-WPIs dried by different three methods on their flow ability, particle size, morphology and in vitro release behavior were studied. After preparing PR-5 sustained release protein tablets with S-WPIs as the carrier by direct powder compression method, the drug release were studied in vitro and the oral pharmacokinetics and bioavailability was evaluated using in vivo dog model. It was observed that concentration of subs
