In this paper, different formulation types of microparticulate systems such as beads, microbeads, microspheres and microsponges using to special attention chitosan, alginate and eudragit RS 100 are reviewed. Chitosan and alginates are natural, anionic or cationic, biocompatible, biodegredable and non-toxic polymers. They have excellent potential for pharmaceutical and biopharmaceutical applicat...

The vaginal route of administration is an alternative for several treatments for either local or systemic pharmacological effects. However, the permanence of a drug in this route represents a challenge for formulation development that can be overcome by using nanoencapsulation and chitosan gel. Thus, this work aimed to evaluate the performance of chitosan hydrogels containing cationic and anion...

The response surface methodology (RSM) including polynomial equations has been used to design an optimal patch formulation with appropriate adhesion and flux. The patch formulations were composed of different polymers, including Eudragit RS 100 (ERS), Eudragit RL 100 (ERL) and polyvinylpyrrolidone K30 (PVP), plasticizers (PEG 400), and drug. In addition, using terpenes as enhancers could increa...
