醫(yī)學(xué)免費(fèi)論文:RP-HPLC法同時(shí)測(cè)定復(fù)方環(huán)昔滴眼液中兩組分的含量
【摘要】 目的：建立同時(shí)測(cè)定復(fù)方環(huán)昔滴眼液中鹽酸環(huán)丙沙星和阿昔洛韋的含量的RP-HPLC法。方法：采用Kromasil C18柱(4.6 mm×250 mm,5 μm)，以15∶15∶70比例的甲醇-乙腈-0.05 mol·L-1枸櫞酸溶液(三乙胺調(diào)pH至3.5)為流動(dòng)相，流速為0.8 mL·min-1;檢測(cè)波長(zhǎng)為253 nm。結(jié)果：鹽酸環(huán)丙沙星和阿昔洛韋的線性范圍分別為15.1～241.6 μg·mL-1(r=0.9993)和5.1～81.6 μg·mL-1(r=0.9998)，平均回收率分別為99.7%和99.8%，RSD分別為0.92%和0.65%。結(jié)論：本法快速準(zhǔn)確，重現(xiàn)性好，適用于復(fù)方環(huán)昔滴眼液的質(zhì)量控制。

復(fù)方環(huán)昔滴眼液是鄖陽(yáng)醫(yī)學(xué)院附屬東風(fēng)總醫(yī)院開(kāi)發(fā)的自制制劑，主要有效成分為鹽酸環(huán)丙沙星(以環(huán)丙沙星計(jì)3 mg·mL-1)和阿昔洛韋(1 mg·mL-1)，主要輔料為透明質(zhì)酸鈉(2 mg·mL-1)。其中鹽酸環(huán)丙沙星是第三代喹諾酮類(lèi)廣譜抗菌藥物，阿昔洛韋為高效抗病毒藥;透明質(zhì)酸鈉作為主要的輔料，與眼球表面黏蛋白具有一種特殊的親和力，故具有緩釋、物理增黏和鋪展?jié)櫇衲芰1]。目前國(guó)內(nèi)已有用高效液相色譜法測(cè)定其他制劑中鹽酸環(huán)丙沙星和阿昔洛韋各自含量的報(bào)道[2-4]，但該制劑目前尚未見(jiàn)同時(shí)測(cè)定二者含量的方法報(bào)道，為更好地控制該產(chǎn)品的質(zhì)量，本研究中建立了同時(shí)測(cè)定復(fù)方環(huán)昔滴眼液中鹽酸環(huán)丙沙星和阿昔洛韋的含量的反相高效液相色譜法，該法簡(jiǎn)便、快速、準(zhǔn)確，可作為復(fù)方環(huán)昔滴眼液的質(zhì)量控制方法。
