Use of combined nanocarrier system based on chitosan nanoparticles and phospholipids complex for improved delivery of ferulic acid. Int J Biol Macromol 2021; 171:288-307. [PMID: 33418046 DOI: 10.1016/j.ijbiomac.2020.12.211] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 12/17/2020] [Accepted: 12/29/2020] [Indexed: 02/05/2023]
Abstract
A novel nanocarrier system of phospholipids complex loaded chitosan nanoparticles (FAPLC CNPs) was developed to improve the oral bioavailability and antioxidant potential of FA. FAPLC CNPs were optimized using a Box-Behnken Design (BBD). FAPLC CNPs were characterized using differential scanning calorimetry, Fourier transforms infrared spectroscopy, powder x-ray diffractometry, proton nuclear magnetic resonance, solubility, in vitro dissolution, ex vivo permeation, and in vivo antioxidant activity in carbon tetrachloride (CCl4)-induced albino rat model. The characterization studies indicated a formation of the complex as well as FAPLC CNPs. The FAPLC CNPs exhibited a lower particle size ~123.27 nm, PDI value ~0.31, and positive zeta potential ~32 mV respectively. Functional characterization studies revealed a significant improvement in the aqueous solubility, dissolution, and permeation rate of FAPLC and FAPLC CNPs compared to FA and FA CNPs. The FAPLC CNPs showed significant enhancement of in vivo antioxidant activity of FA by restoring the elevated marker enzymes in the CCl4-intoxicated rat model compared to FA CNPs. Moreover, the pharmacokinetic analysis demonstrated a significant enhancement of oral bioavailability of FA from FAPLC CNPs compared to FA CNPs. These findings show that FAPLC CNPs could be used as an effective nanocarrier for improving the oral delivery of FA.

ACS OMEGA 2020; 5:1708-1716. [PMID: 32010845 PMCID: PMC6990636 DOI: 10.1021/acsomega.9b04004] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 12/30/2019] [Indexed: 05/17/2023]
Abstract
Glipizide (GLZ) is an oral hypoglycemic agent, which is a weakly aqueous soluble drug. The solubility values of GLZ in various neat solvents are scarce in the literature. Hence, the solubility of GLZ in 12 different neat solvents, namely, "water, methanol, ethanol, isopropanol (IPA), 1-butanol, 2-butanol, ethylene glycol (EG), propylene glycol (PG), poly(ethylene glycol)-400 (PEG-400), ethyl acetate (EA), dimethyl sulfoxide (DMSO), and Transcutol-HP (THP)", at "T = 298.2-318.2 K" and "p = 0.1 MPa" was measured. The recorded solubilities of GLZ were correlated by "van't Hoff and Apelblat models" using root-mean-square deviation (RMSD). The overall RMSD was obtained as 1.21 and 1.40% for "Apelblat and van't Hoff models", respectively. Different solubility parameters of all studied materials including drug and solvent were calculated to find the best solvent for GLZ. The solubilities of GLZ (expressed in mole fraction) have been found highest in DMSO (2.81 × 10-2), followed by THP, EA, 2-butanol, 1-butanol, IPA, PEG-400, ethanol, PG, methanol, EG, and water (1.98 × 10-4) at "T = 318.2 K". All investigated solubility parameters of GLZ were recorded very close to the DMSO. "Apparent thermodynamic analysis" showed an "endothermic and entropy-driven dissolution" of GLZ in the 12 different neat solvents. The highest molecular interactions were recorded in GLZ-DMSO compared to other combinations. Overall, DMSO has been considered as the best solvent for the solubilization of GLZ.
