Release of nifedipine, furosemide, and niclosamide drugs from the biocompatible poly(HEMA) hydrogel structures

Authors: BAHAR YILMAZ

Abstract: The primary aim of this article was to improve the solubility and bioavailability of the drugs nifedipine, niclosamide, and furosemide due to their poor solubility and dissolution rate. Therefore, these drugs require improvement in solubility and dissolution rate in formulation development, especially in solid dosage forms such as hydrogels and capsules. Hydrogel structures were synthesized by using a biocompatible, nontoxic, and protective pure 2-hydroxy ethyl methacrylate (HEMA) monomer. These hydrogel structures were characterized by various techniques such as scanning electron microscopy and Fourier-transformed infrared spectroscopy. In the next step, drug molecules were loaded in the poly (HEMA) hydrogels. Drug releases of drug-loaded hydrogel structures were measured at certain time intervals and recorded cumulatively (%). The pH affinity, morphology, structure, drug release, swelling, and cytotoxic effect of the resulting materials were studied in detail. In addition to investigating the biocompatibility and cytotoxicity of the poly (HEMA) hydrogel, we evaluated an in vitro cytotoxicity assay on MCF-7and MIA PaCa-2 and HEK 293 cell lines with the hydrogel structure and confirmed cell viability of over 85%. These results suggest that our HEMA polymeric hydrogel is a material with biological importance and great pharmacological potential as a supporting material in the drug release of nifedipine, furosemide, niclosamide, and similar drug molecules.
