Tetrandrine is a drug that has anti-fibrosis effects. In this study, chitosan-tripolyphosphate (TPP) beads containing tetrandrine was made and evaluated for <em>in vitro</em> release profile and <em>in vivo</em> targeted test.</p><p><strong>Methods: </strong>Chitosan-TPP tetrandrine beads were prepared by ionic gelation method with variation in sodium tripolyphosphate concentration: 3% (Formula 1), 4% (Formula 2), and 5% (Formula 3). All formulae were characterized for its morphology, particle size, moisture content, process efficiency, entrapment efficiency, thermal character, crystallinity, and swelling. Then, the best formula was coated with HPMCP HP-55, CAP, Eudragit L100-55, or Eudragit L100 prior to drug release profile <em>in vitro</em> and <em>in vivo</em> test.</p><p><strong>Results: </strong>Beads from all formulae had an average size: 920.50±0.04 µm, 942.21±0.08 µm, and 1085.95±0.03 µm; Water content: 7.28±0.003%, 5.64±0.005%, and 6.84±0.004%; Process efficiency: 29.70%, 28.96%, and 29.70%; Entrapment efficiency: 16.20±0.63%, 17.02±0.37%, and 20.42±0.70% for Formula 1, 2, and 3, respectively. In addition, the results of <em>in vitro </em>cumulative drug release were 67.36%, 76.04%, 83.12%, 83.21%, 40.16%, 37.98%, 45.86%, 41.71% for Formula 3A-3H, respectively.</p><p><strong>Conclusion: </strong>It can be concluded that Formula 3D (CAP 15%) was chosen as a formulation with the best <em>in vitro</em> profile. Moreover, the <em>in vivo</em> targeted test showed that Formula 3D was able to deliver the beads to the intestine compared to the control beads.</p></div>}, number={5}, journal={International Journal of Applied Pharmaceutics}, author={Iswandana, Raditya and Putri, Kurnia Sari Setio and Dwiputra, Randika and Yanuari, Tryas and Sari, Santi Purna and Djajadisastra, Joshita}, year={2017}, month={Sep.}, pages={109–115} }
