Simultaneous Determination of Dioxopromethazine and Phenylephrine in Eye DropsUsing Capillary Isotachophoresis


Izotachoforetické stanovenie dioxoprometazínu vedľa fenylefrínu v očnej instilácii

Dioxoprometazín bol stanovovaný vedľa fenylefrínu v očnej instilácii metódou kapilárnej izotachoforézy.Boli preskúšené dva elektrolytové systémy s rôznym zložením a rôznym pH. Očná instiláciasa pred analýzou riedila vodou v pomere 1:50. Bola hodnotená presnosť, správnosť, linearita,robustnosť a selektivita ITP metódy pre obidva systémy.

Klíčová slova:
izotachoforéza – dioxoprometazín – fenylefrín – očná instilácia – validácia

Overview

Dioxopromethazine and phenylephrine were determined simultaneously in eye drops using themethod of capillary isotachophoresis. Two elektrolyte systems with different compositions and pHwere examinated. Prior to analysis, the eye drops are diluted with water in a ratio 1:50. Precision,correctness, linearity, robustness, and selectivity of the ITP method were evaluated for bothelectrolyte sytems.

Key words:
isotachophoresis – dioxopromethazine – phenylephrine – eye drops – validation
