Abstract
U ovom radu ispitivana je mogućnost solubilizacije deksametazona kao teško topljive djelatne tvari, neionskog solubilizatora tiloksapola i Krebs-Ringerova pufera kao složene otopine elektrolita, a sve pri temperaturi od 34°C koja je karakteristična za mjesto apsorpcije djelatne tvari. Sadržaj otopljenog/solubiliziranog deksametazona određena je spektrofotometrijski pri =241nm. Topljivost deksametazona se pri koncentracijama tiloksapola manjim od cmc (kritične micelizacijske koncentracije) ne mijenja, a kad koncentracija tiloksapola dosegne koncentracije veće od cmc dolazi do porasta topljivosti što je posljedica micelarne solubilizacije. Veličina i disperznost micela određena je fotonskom korelacijskom spektroskopijom. Ako se usporedi veličina micela tiloksapola i veličina micela tiloksapola sa uklopljenim deksametazonom vidi se da se veličina micela znatno ne mijenja pa se može zaključiti da su nastali micelarni sustavi stabilni.
Abstract (english)
In this study we examined the possibility of solubilization ability of dexamethasone as a sparingly soluble active substance, a nonionic solubilizer tyloxapol and Krebs-Ringer buffer solution as the electrolyte complex, and all at a temperature of 34 ° C which is characteristic for the location of absorption of the drug. The content of dissolved / solubilized dexamethasone was determined spectrophotometrically at  = 241nm. Solubility of dexamethasone at concentrations of tyloxapol which are less than cmc (critical micelizacijske concentration) do not change, and when the concentration reaches tyloxapol concentration greater than cmc, an increase in solubility as a result of micellar solubilization. The size and dispersity of the micelles was determined by photon correlation spectroscopy. If one compares the size of the micelles tyloxapol and size micelles tyloxapol fitted with dexamethasone it can be seen that the size of the micelles did not change so it can be concluded that the resulting micellar systems are stable.
