FD1 (100% alginate) and FD2 (70% alginate) formulations showed similar release patterns due to the higher content of alginate, which formed stable microparticles compared to FD3 (50% alginate).
it was noted that the fd3 microparticles were completely eroded after 7 h in simulated gastrointestinal fluid, while the other formulations were progressively degraded over time.
