Extended Release of a Novel Antidepressant, Venlafaxine, based on Anionic Polyamidoamine Dendrimers and Poly(Ethylene Glycol)-Containing Semi-Interpenetrating Networks
Abstract
The multiple daily administration of venlafaxine, a novel third-generation antidepressant, was reduced based on polyamidoamine and polyethylene glycol (PEG)-containing semi-interpenetrating network (IPN), respectively. Venlafaxine was covalently linked to water-soluble G2.5 anionic polyamidoamine dendrimer via a hydrolyzable ester bond. Semi-IPN hydrogels were prepared by crosslinking acrylamide in the presence of PEG, and venlafaxine with predetermined amounts was loaded in situ. Dendrimer-venlafaxine conjugate and semi-IPNs were characterized by proton nuclear magnetic resonance and Fourier transform infrared, respectively. The effect of PEG concentration and molecular weight was studied and discussed for an optimal controlled release.
