Preparation, Characterization and Evaluation of Flavonolignan Silymarin Effervescent Floating Matrix Tablets for Enhanced Oral Bioavailability

The convenient and highly compliant route for the delivery of active pharmaceutical ingredients is the tablet. A versatile platform of tablets is available for the delivery of therapeutic agents to the gastrointestinal tract. This study aimed to prepare gastro retentive drug delivery floating tablets of silymarin to improve its oral bioavailability and solubility. Hydroxypropyl methylcellulose (HPMCK4M and HPMCK15), Carbopol 934p and sodium bicarbonate were used as a matrix, floating enhancer and gas generating agent, respectively. The prepared tablets were evaluated for physicochemical parameters such as hardness, weight variation, friability, floating properties (floating lag time, total floating time), drug content, stability study, in vitro drug release, in vivo floating behavior and in vivo pharmacokinetics. The drug–polymer interaction was studied by Differential Scanning Calorimetry (DSC) thermal analysis and Fourier transform infrared (FTIR). The floating lag time of the formulation was within the prescribed limit (<2 min). The formulation showed good matrix integrity and retarded the release of drug for >12 h. The dissolution can be described by zero-order kinetics (r2 = 0.979), with anomalous diffusion as the release mechanism (n = 0.65). An in vivo pharmacokinetic study showed that Cmax and AUC were increased by up to two times in comparison with the conventional dosage form. An in vivo imaging study showed that the tablet was present in the stomach for 12 h. It can be concluded from this study that the combined matrix system containing hydrophobic and hydrophilic polymers min imized the burst release of the drug from the tablet and achieved a drug release by zero-order kinetics, which is practically difficult with only a hydrophilic matrix. An in vivo pharmacokinetic study elaborated that the bioavailability and solubility of silymarin were improved with an increased mean residence time.

“…This might be because the Cu/Zn ratio of CuZn@NC-1 is better suited to exploiting the bimetal’s synergistic effect, resulting in excessively low electron transfer impedance at the electrode surface. This also implies that the CuZn@NC-1 electrode surface has the fastest electron transfer rate [ 39 , 40 ].…”

The Cu/Zn-zeolitic imidazolate framework (Cu/Zn-ZIF) was synthesized using the traditional hydrothermal method, and its surface morphology was controlled by adding polyvinylpyrrolidone (PVP) during its synthesis. It was then calcined at 800 °C to form the nitrogen-containing carbon material CuZn@NC, which improved the electron transfer rate. Scanning electron microscopy (SEM), X-ray crystal diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were used to investigate the surface morphology and structure. Finally, the electrochemical sensing platform for luteolin was effectively constructed by changing the metal–ion ratio during synthesis to achieve the most suitable electrode material. The sensor platform detects luteolin well, with an operating curve equation of Ip (A) = 0.0571C (nM) − 1.2913 and a minimum detection limit of 15 nM, and the platform has been successfully employed for luteolin detection in real samples.

“…This detailed information is essential for understanding the properties and potential applications of MOF materials. [76,78] Thermogravimetric analysis (TGA) is commonly used to assess thermal and oxidative stability, chemical composition, lifespan, decomposition rate, and the effects of the surrounding environment on thermal stability. [79] TGA measures weight changes in a specimen as a function of temperature and/or time in a controlled atmosphere.…”

This review underscores the potential of metal‐organic frameworks (MOFs), exemplified by MIL‐100(Fe), as catalysts in the conversion of 5‐Hydroxymethyl Furfural to 2,5‐Furan Dicarboxylic Acid, which is crucial in bioplastics and value‐added chemical production. MOFs exhibit advantages, including recyclability, stability, and catalytic potential under mild conditions. Despite promising results, MOFs in this application are underexplored compared to traditional metal catalysts. Noble metal catalysts (Au, Pt, and Pd) face challenges such as cost and limited recyclability. Mechanistic studies favor the DFF route, highlighting the oxidation of HMF's hydroxyl group as predominant. Molecular oxygen proves effective for HMF to FDCA transformation, with gold‐based catalysts noted for selectivity. Ongoing industrial efforts by companies like Avantium indicate a shift towards sustainable alternatives. This review highlights research gaps concerning the necessity for custom Metal‐Organic Framework (MOF) catalysts in the transformation of hydroxymethylfurfural (HMF) into 2,5‐furandicarboxylic acid (FDCA). The study recommends, among other things, 1) the adoption of base‐free conversion systems, 2) a focus on large‐scale FDCA manufacturing, prioritizing environmental sustainability despite prevailing cost challenges, and 3) fostering multidisciplinary collaboration. Utilizing advanced engineering software, such as ASPEN HYSYS, is proposed for optimizing these processes and paving the way for the successful industrialization of FDCA in the future.
