Abstract

The semi interpenetrating network hydrogels (Z1-Z15) were prepared from different ratio of sodium alginate and linear poly (acrylamide-co-diallyl dimethyl ammonium chloride) then they mixed with the acrylamide and bisacrylamide as cross linking agent and polymerized via redox polymerization to form the semi-IPNs. All prepared semi-IPNs were loaded with three different amounts from Gabapentin as drug model. The swelling characteristics were studied for all semi- IPN hydrogels by determining the swelling ratio (Q).The release of Gabapentin was followed by using U.V. spectroscopy at (202 , 201 and 204) nm at constant temperature (37ºC) in distilled water , simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) respectly. The results of Gabapentin released indicated that all semi-IPNs have the ability to release drug to environment and the amount of Gabapentin released about 50% during two hours. Higuchi equation was used to determine the Higuchi constant which is very useful to forecasting the amount of Gabapentin released theoretically.
