Drug release from collagen matrices is in most cases governed by diffusion from swollen matrices but also enzymatic matrix degradation or hydrophobic drug/collagen interactions may contribute. To reduce water uptake and to prolong the release, insoluble collagen matrices have been chemically or dehy

The influence of commonly used excipients, spray-dried lactose (SDL), microcrystalline cellulose (MCC), and partially pregelatinized maize starch (Starch 1500 1 ) on drug release from hydroxypropyl methylcellulose (HPMC, hypromellose) matrix system has been investigated. A model formulation containe
Chitosan diacetate (CDA) was prepared by alkylating the amino moieties of chitosan with mono-iodoacetic acid. Subsequently, CDA was cross-linked with Al 3รพ , Zn 2รพ , and Ca 2รพ ions to yield three ionotropically crosslinked polymeric matrices. These composite matrices were characterized employing inf
