Carboxymethyl cellulose-rosin gum hybrid nanoparticles: An efficient drug carrier.
Adequate release of 5-ASA in colon is challenging as it easily permeates at the acidic pH of the upper gastrointestinal tract. Targeting delayed release of 5-ASA at acidic pH, Carboxymethyl cellulose-rosin gum hybrid nanoparticles (CRNP3 ) with an average size of 267nm have been crafted through nanoprecipitation method. CRNP3 was extensively characterized using Fourier Transform Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and particle size analysis based on dynamic light scattering. Colon specific targeted in-vitro release of 5‑Aminosalicylic acid from CRNPs was monitored in simulated gastric (SGF) and intestinal (SIF) fluids. The release rate was very slow in first 2h in SGF, while in SIF, it was greater and 72% drug was released in a controlled manner during the time span of 12h in contrast to native carboxymethyl cellulose or rosin gum for which 100% release was accomplished within 5h or 8h respectively. The delayed release from CRNPs is attractive for enhancing the bioavailability of drug in colon. The drug release followed zero-order kinetics and non-Fickian diffusion mechanism.
