Preparation and characterization of phase-separated hydrogels based on gelatin and hydroxypropyl methylcellulose for vaginal drug delivery applications Rajeshree Panigrahi, Jajnadatta Panda, Ajit Kumar Acharya, Biswaranjan Mohanty, Iswori Prasad Padhy, Deepak Kumar Dash Research Journal of Pharmacy and Technology, 2025 Objective: The objective of this work was to formulate and characterize a series of phase-separated hydrogel formulations based on gelatin and hydroxypropyl methylcellulose (HPMC) for controlled delivery applications. Methods: The hydrogel was evaluated for physicochemical properties such as swelling index, mechanical strength, and pH compatibility. Thermal stability was assessed using Thermo Gravimetric Analysis (TGA/DSC), while microscopy confirmed phase separation. Biocompatibility and stability were examined under different storage conditions. Drug release kinetics and mechanisms were analyzed, and FTIR was used to identify material interactions. Result: Gelatin/HPMC hydrogels were prepared via segregative phase separation and stabilized with glutaraldehyde to enhance structural integrity. The hydrogels exhibited hydrogen bonding, pH-responsive swelling, and mechanical properties influenced by HPMC viscosity. Moisture content was consistent across formulations (80-85%). Higher HPMC viscosity reduced swelling at acidic pH, altered mechanical strength, and slowed drug release by forming a robust gel network. Conclusion: Gelatin/HPMC-based phase-separated hydrogels demonstrate potential as pH-sensitive intravaginal drug delivery systems, offering sustained and controlled release of antibiotics. FTIR confirmed strong hydrogen bonding, while swelling, impedance, and mechanical studies highlighted the influence of HPMC content on hydrogel properties. These biodegradable hydrogels are flexible, user-friendly, and effective for localized therapeutic delivery. Discussion: This study develops pH-sensitive hydrogels made from gelatin and hydroxypropyl methylcellulose (HPMC) for controlled intravaginal drug delivery. These hydrogels, which degrade after use, exhibit enhanced water retention, controlled drug release, and pH-responsive swelling behaviour, indicating their potential as effective drug delivery systems.
SOLUBILITY ENHANCEMENT OF RIVAROXABAN BY SOLID DISPERSION WITH POLYETHYLENE GLYCOL 4000 RUCHITA KUMARI PATRA, AJIT KUMAR ACHARYA, ANJAN KUMAR MAHAPATRA, PADALA NARASIMHA MURTHY International Journal of Applied Pharmaceutics, 2023 Objective: The aim of the work was to enhance the dissolution rate of rivaroxaban by preparing its solid dispersions (SDs) using hydrophilic carrier PEG 4000. Methods: The SDs of rivaroxaban with PEG 4000 were prepared at 1:1, 1:2 and 1:3 w/w ratios by physical mixing, melting and solvent evaporation techniques. The prepared solid dispersions were characterized by Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). Results: Both the solubility and dissolution rate of the drug in these formulations were increased. The used hydrophilic carriers showed a more than two-fold increase in dissolution rate in their prepared solid dispersions by melting or solvent evaporation techniques. The pure drug rivaroxaban as the pure drug shows a dissolution rate of nearly 39 % after 60 m, whereas the solid dispersions by melting or solvent evaporation showed 90% of dissolution after 60 m. The FTIR spectroscopic and DCS thermal studies showed the compatibility of rivaroxaban and the absence of well-defined drug polymer interactions, though the shift in peaks was observed due to the formation of new bonds. Conclusion: Formulation of solid dispersions of drug with hydrophilic carriers is a successful approach for solubility or dissolution rate enhancement of low soluble drug(s). In this work for solubility enhancement of rivaroxaban the hydrophilic carrier PEG 4000 showed significant solubility enhancement.
