                            <p>Naproksen sodium  NAS  orta ve şiddetli ağrıların giderilmesinde  yaygın olarak kullanılan non-steroidal anti-inflamatuar bir ilaçtır. Bu  çalışmada NAS’ın in-vitro çözünürlüğünün tayini için basit ve duyarlı  bir yüksek basınçlı sıvı kromatografisi yöntemi tanımlanmaktadır.  NAS’ın ayrımı, ters-faz kolon  Waters Spherisorb S10 ODS2 C18 200x4.6  mm  ile 1 mL.dk-1 akış hızında 0.05 M fosfat tamponu  pH 4.0 , metanol  ve asetonitril  50:20:30 h/h ’den oluşan mobil fazı kullanılarak  gerçekleştirilmiştir. NAS’ın kromatografik tayini UV dedektör sistemi ile  230 nm’de gerçekleştirilmiştir. Alıkonma süresi yaklaşık 7 dk’dır. Kalibrasyon  doğrusu 5-150 μg.mL-1 konsantrasyon aralığında doğrusaldır.  Kantitatif olarak tayin edilebilen en düşük konsantrasyon 78 ng.mL-1  olarak bulunmuştur. Gün-içi ve günler-arası bağıl standart sapması %  3.7 ya da daha az, ve doğruluk ise eklenen konsantrasyondan % 5.4’lük  bir sapma göstermiştir. Geliştirilen yöntem NAS’ın çözünürlük tayinlerine  başarıyla uygulanmıştır.</p></trans-abstract>

This study presents a simple and sensitive high-performance liquid chromatographic  method for the determination of in-vitro solubility of NAS.  Chromatographic separation of NAS was achieved on a reversed-phase  column  Waters Spherisorb S10 ODS2 C18 200x4.6 mm column  with  the mobile phase consisted of 0.05M phosphate buffer  pH 4.0 , methanol  and acetonitrile  50:20:30 v/v , at a flow rate 1 mL.min-1. Chromatographic  detection of NAS was performed at 230 nm with UV detector system.  The retention time was about 7 min. Calibration curve was linear  over the concentration range of 5-150 μg.mL-1. The limit of quantitation  was found to be 78 ng.mL-1. The intra- and inter-day precision relative  standard deviation was 3.7% or less, and the accuracy was within 5.4%  deviation of the nominal concentration. The proposed HPLC method was  successfully applied to the analysis of NAS solubility.</p></abstract>
