dc.description.abstract | Targeted drug delivery is powerful tool which researchers use to achieve safer and more efficient
therapy of many diseases, including various types of cancer. Many chemotherapeutics are poorly watersoluble, so their encapsulation and targeted delivery remain quite challenge. Hydrogels based on
poly(methacrylic acid) (PMAA) are widely investigated for targeted drug delivery due to their pH
sensitivity, non-toxicity and biocompatibility. Still, due to the PMAA highly hydrophilic nature, PMAA
can only be used for encapsulation and targeted delivery of water-soluble drugs. Our previous research
was directed towards overcoming this limitation: PMAA was modified with amphiphilic protein –
casein and poorly-water soluble model drug – caffeine – was encapsulated (PMAC). Present study is
focused on investigation how variation of amount of one of the most important hydrogels network
parameter such as crosslinker affect PMAC swelling properties and caffeine release. The group of
hybrid hydrogels – PMAC – was synthesized with various amount of crosslinker: 0.4mol%, 0.8mol%,
1.6mol% and 3.2mol% with respect to methacrylic acid. Swelling behavior of hybrid hydrogels and
caffeine release was investigated in two environments which simulated human stomach and intestines.
Obtained results showed that targeted delivery of poorly water-soluble model drug was achieved and
that its release can be prolonged up to 24h. Also, kinetic of poorly water-soluble drug release can be
easily modified only by changing crosslinker amount. PMAC hybrid hydrogels have huge potential for
targeted delivery of poorly water-soluble active substances. | sr |
