Enteric complex layer-coated controlled release of capsaicin from phytosterol/γ-cyclodextrin microparticles via guest exchange reaction with taurocholic acid. Eur J Pharm Sci 2021; 168:106038. [PMID: 34637895 DOI: 10.1016/j.ejps.2021.106038] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 09/10/2021] [Accepted: 09/29/2021] [Indexed: 02/05/2023]
Abstract
Phytosterol (PSE)/γ-cyclodextrin (γ-CD) microparticles have a capsule-like structure, wherein the hydrophobic PSE core is surrounded by outer layers of the hydrophilic PSE/γ-CD inclusion complex crystal. The microparticles could mask the undesirable taste of capsaicin (CAP) by encapsulation of CAP into the microparticles. In the present study, the dissolution of CAP from PSE/γ-CD microparticles into artificial intestinal fluids was examined using the paddle method. The dissolution of CAP from the microparticles was suppressed at pH 1.2 and 5.0. On the other hand, the dissolution was significantly enhanced in fasted and fed state simulated intestinal fluid (FaSSIF and FeSSIF) . Taurocholate (TCA), contained in these artificial fluids, induced rapid dissolution of CAP from microparticles. The mechanism of CAP dissolution from the microparticles in the presence of TCA was investigated using in situ1H NMR spectroscopy. During the incubation of the mixed suspension of the microparticles and TCA, γ-CD peaks started to appear, and the TCA peak showed a gradual upfield shift. Quantitative analysis of NMR results showed that the TCA/γ-CD inclusion complex could form during incubation, according to the dissolution of γ-CD from the microparticles via the guest exchange reaction of PSE by TCA. The collapse of the PSE/γ-CD inclusion complex crystal at the outer shell of microparticles could trigger the release of CAP into the intestinal fluid. Thus, PSE/γ-CD microparticles can be used as an enteric controlled-release system that releases encapsulated drugs not via the conventional pH changes but via guest exchange reaction with TCA.

Abstract
Bile salts are present in the intestines of humans as well as the animals used during the development of pharmaceutical products. This review provides a short introduction into the physical chemical properties of bile salts, a description of the bile concentration and composition of bile in different animal species and an overview of the literature investigating the influence of bile salts on the in vivo performance of different compounds and drug formulations. Generally, there is a positive effect on bioavailability when bile is present in the gastro-intestinal tract, independent of the formulation systems, e.g. suspensions, solutions, cyclodextrin complexes or lipid based formulations, but a few exceptions have also been reported.

Abstract
The complexation of 6 bile salts with various methylated β-cyclodextrins was studied to elucidate how the degree and pattern of substitution affects the binding. The structures of the CDs were determined by mass spectrometry and NMR techniques, and the structures of the inclusion complexes were characterized from the complexation-induced shifts of (13)C nuclei as well as by 2D ROESY NMR. Thermodynamic data were generated using isothermal titration calorimetry. The structure-properties analysis showed that methylation at O3 hinders complexation by partially blocking the cavity entrance, while methyl groups at O2 promote complexation by extending the hydrophobic cavity. Like in the case of 2-hydroxypropylated cyclodextrins, the methyl substituents cause an increased release of ordered water from the hydration shell of the bile salts, resulting in a strong increase in both the enthalpy and the entropy of complexation with increased number of methyl substituents. Due to enthalpy-entropy compensation the effect on the stability constant is relatively limited. However, when all hydroxyl groups are methylated, the rigid structure of the free cyclodextrin is lost and the complexes are severely destabilized due to very unfavorable entropies.

Abstract
The effect of the degree of substitution (DS) on the ability of hydroxypropylated β-cyclodextrin (HPβCD) to form inclusion complexes with six different bile salts, found within the intestinal tracts of rats, dogs, and humans, was studied by isothermal titration calorimetry. The composition and molecular structure of the cyclodextrin samples were characterized by MALDI-TOF mass spectrometry together with 1D and 2D-NMR, and some of the complexes were studied by 2D ROESY NMR. The stability and structure of the complexes were mainly determined by the position of hydroxyl groups on the bile salts and depended relatively little on the number of hydroxypropyl side chains on the CDs. The enthalpy and entropy of complexation exhibited a strong linear increase as the DS increased from 0 to 1, and a pronounced enthalpy-entropy compensation was observed. These observations are interpreted as an increased release of ordered water from the hydration shells of the bile salts, caused by the hydroxypropyl substituents on the rim of the CD. It is estimated that each CD hydroxypropyl substituent dehydrates a hydrophobic surface area of approximately 10 Å(2).
