Abstract

A capillary zone electrophoresis method with ultraviolet detection for the simultaneous determination of Olmesartan medoxomil and Hydrochlorothiazide in synthetic tablets was developed. Since the Olmesartan medoxomil was not stable in aqueous solutions, first it was converted to its degradation product and then analyzed indirectly. A fused silica capillary 50 μm internal diameter, 48.5 cm total length, 40 cm effective length was used and the separation was obtained by 40 mM pH 9.5 borate buffer followed by detection with an ultraviolet detector at 210 nm. The analysis were performed at a temperature of 30 °C with the application of 3 seconds hydrodynamic injection at 50 mbar pressure and a applied potential of 30 kV. Diflunisal IS was used as internal standard. The developed method was validated according to the literature.

Özet

Olmesartan Medoksomil ve Hidroklorotiazidin sentetik tabletlerden aynı anda analizi için UV dedetörün kullanıldığı bir capiler elektroforez yöntemi geliştirilmiştir. Olmesartan Medoksomil sulu çözeltilerde kararlı olamdığı için once bozunma ürününe çevrilmiş ve ardından dolaylı yoldan analiz edilmiştir. Eritilmiş silica kapiler 50 μm iç çap, 48.5 cm toplam uzunluk, 40 cm efektif uzunluk kullanılmış ve ayrım 40 mM pH 9.5 borat tamponunda 210 nm dalga boyunda ultraviole dedektör kullanılarak gerçekleştirilmiştir. Analizler, 30 0C’ de, 50 mbar basınç uygulanarak 3 saniye hidrodinamik enjeksiyonla ve 30 kV uygulama potansiyeli altında yapılmıştır. Diflunisal IS , iç standart olarak kullanılmıştır. Yöntem, literature uygun olarak valide edilmiştir.
