HSS infusion solutions were prepared and stored as recommended by the manufacturer and under common conditions in our hospital. The effects of HSS concentration (1 and 4 mg/mL), solvent (isotonic saline and glucose), temperature (ambient and 30°C), and light on its stability were evaluated using a validated stability-indicating HPLC-UV method. HSS degradation followed first-order kinetics. No significant difference in its stability was observed between the two evaluated concentrations, solvents and light exposure (t95% between 25 and 30 h). Elevated temperature (30°C) affected HSS stability and significantly reduced the t95% (4.6-6.3 h). HSS infusion solutions are physically and chemically stable (?5% degradation) for at least 6 h if stored below 30°C. The in-use stability may be extended up to 24 h if stored below 24°CNamen te študije je opredelitev stabilnosti in določitev roka uporabnosti med uporabo (t95%) raztopin za infundiranje z natrijevim hidrokortizonsukcinatom (HSS) ter zagotovitev na dokazih podprtih priporočil o njihovi uporabnosti. Infuzijske raztopine HSS smo pripravili in shranjevali v skladu s priporočili proizvajalca in pri običajnih pogojih v naši bolnišnici. Z validirano stabilnostno indikativno HPLC-UV metodo smo ugotavljali vpliv koncentracije HSS (1 in 4 mg/mL), topila (izotonična fiziološka raztopina in raztopina glukoze), temperature (sobna in 30 °C) in svetlobe na njegovo stabilnost. Razgradnja HSS je sledila kinetiki prvega reda. Ugotovili smo, da različni preiskovani koncentraciji HSS, obe topili in izpostavljenost svetlobi niso značilno vplivali na stabilnost HSS (t95% med 25 in 30 urami), medtem ko je povišana temperatura (30 °C) značilno skrajšala t95% (4,6–6,3 ur). Infuzijske raztopine HSS so fizikalno in kemično stabilne (<5 % razgradnja) vsaj 6 ur pri temperaturi do 30 °C in najdlje 24 ur pri temperaturi do 24 °CTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
