Controllled release of metropolol tartrate from nanoporous silica matrices
No full textA series of nanoporous silica matrices (a silica gel matrix and two ordered mesoporous silica)
have been investigated as potential carriers for the controlled release of metoporolol tartrate a
selective β1 receptor blocker used in the treatment of several diseases of the cardiovascular system.
Particular attention was devoted to the optimization of a reproducible and fast synthetic procedure.
The morphology, structure and chemical nature of the porous surfaces were characterized by N2
physisorption, X-ray diffraction, HR-TEM and FT-IR analyses. The delivery profiles were collected in
vitro in physiological solution a pH 7.4.
We have observed a close correlation between the drug release kinetic and the textural properties of
the carriers in particular with their pore size dimension
