| Abstract |
The most important feature in transbuccal drug delivery
is the low drug passage through the buccal mucosa. In
our previous work we demonstrated the aptitude of
Galantamine to penetrate the buccal tissue. The collected
data suggested that Galantamine passively crosses the
membrane, but the calculated Js and Kp values showed
that the drug amount that crosses the membrane wasn’t
sufficient to assure blood therapeutic level. So, in this
study, ex vivo permeation tests, using porcine buccal
mucosa, were performed in presence of physical or
chemical enhancers. No significant differences in
penetration rate were observed using chemical enhancers
as sodium dehydrocholate, EDTA disodium salt and
trisodium citrate dihydrate; while, Js and Kp were
extensively affected by application of electric fields.
Tablets, designed for Galantamine administration on
buccal mucosa, were prepared by direct compression of
drug loaded Eudragit® RS 100 matrices. When the tablets
were coated with lipophilic material, Galantamine is
slowly discharged from buccal tablets, following the
Higuchian kinetic. Buccal tablets containing Galantamine
may represent a potential alternative dosage form in
Alzheimer management. |
