Abstract
Objective: Trimethoprim is a wide-spectrum antimicrobial compound belonging to Class II of the Biopharmaceutics Classification System (BCS), with high permeability but low solubility. This study aimed to prepare a multicomponent crystal (MCC) of trimethoprim-mandelic acid to enhance the solubility of trimethoprim.
Methods: MCC trimethoprim–mandelic acid was prepared by spray drying technique. Solid-state characterizations were performed by using PowX-ray diffraction (PXRD), Differential Scanning Calorimetry (DSC), Fourier-transform infrared (FT IR) spectroscopy, Scanning Electron Microscopy (SEM), and polarized microscopy. The solubility test was performed in distilled water. The amount of dissolved trimethoprim was analyzed by High-Performance Liquid Chromatography (HPLC) using acetonitrile and phosphoric acid 1 % (10:90 v/v) as the mobile phase.
Results: MCC characterizations showed a different diffraction pattern from its intact materials according to PXRD analysis, a decrease in the melting point in the DSC thermogram, a shift of the wave number in the FT-IR spectra, and a new crystalline habit compared to the intact materials was presented by SEM analysis. The MCC also showed the color of interference under polarized microscopy, indicating the crystalline phase. The solubility of trimethoprim in MCC increased significantly by 3.98 times in comparison to intact trimethoprim.
Conclusion: The MCC trimethoprim-mandelic acid by spray drying technique enhanced the solubility of trimethoprim.
期刊介绍：
International Journal of Applied Pharmaceutics (Int J App Pharm) is a peer-reviewed, bimonthly (onward March 2017) open access journal devoted to the excellence and research in the pure pharmaceutics. This Journal publishes original research work that contributes significantly to further the scientific knowledge in conventional dosage forms, formulation development and characterization, controlled and novel drug delivery, biopharmaceutics, pharmacokinetics, molecular drug design, polymer-based drug delivery, nanotechnology, nanocarrier based drug delivery, novel routes and modes of delivery; responsive delivery systems, prodrug design, development and characterization of the targeted drug delivery systems, ligand carrier interactions etc. However, the other areas which are related to the pharmaceutics are also entertained includes physical pharmacy and API (active pharmaceutical ingredients) analysis. The Journal publishes original research work either as a Original Article or as a Short Communication. Review Articles on a current topic in the said fields are also considered for publication in the Journal.
