Abstract AR
تضمنت هذه الدراسة على جزأين أساسيين، ضم الجزء الأول تطوير طريقة طيفية لتقدير دواء رانتدين هيدروكلورايد تستند على أكسدة هذا الدواء مع برمنغات البوتاسيوم القاعدية (KMnO4) و متابعة التفاعل طيفيا من خلال قياس التغير بالامتصاص عند طول موجي 600 نانوميتر.
وجد أن الزمن اللازم لتمامية التفاعل هو 30 دقيقة و مدى الخطية يتراوح بين (1 11) مايكرو غرام / مل و معامل الارتباط 0.9981, و حد الكشف مقداره 0.183 مايكرو غرام / مل و قيم الانحراف القياسي النسبي RSD% تتراوح بين (0.58 1.62) %. أما الطريقة الثانية استندت على تحفيز البريق الكيميائي لنظام (لومينول بيروكسيد الهيدروجين كوبلت) بواسطة هذا الدواء و كانت الحدود الخطية للطريقة تتراوح بين (1.0 10.0) مايكرو غرام / مل و بمعامل ارتباط 0.9996 و انحراف قياسي نسبي مئوي يتراوح بين 0.74% 1.00% وحد كشف (0.75) مايكرو غرام / مل . طبقت هاتين الطريقتين بنجاح على المستحضرات الصيدلانية و كان الاسترداد المئوي (97 99) %.
Abstract EN
This study involves development of a simple kinetic spectrophotometric method and a new flow injection-activated chemiluminescence (FIA-CL) for the determination of ranitidine -HCl (R-HCl) in pharmaceutical preparations.
Spectrophotometric method was based on the oxidation of the R-HCl with alkaline potassium permanganate , the reaction is followed spectrometrically by measuring the rate of change of the absorbance at 600 nm.
A fixed-time (at 30min) method is adopted for determining the drug concentration .
The calibration graph was linear in the range of (1 - 7) μg-ml-1 with a correlation coefficient of 0.9981,detection limit of 0.183 μg-ml-1 and a relative standard deviation RSD% of 0.58-1.62%.
The method of FIA-CL was based on the activation of luminol-cobalt-H2O2 chemiluminescence by R-HCl.
The linearity is (1-6) μg-ml-1 with detection limit of (0.75) μg-ml-1 , and correlation coefficient was 0.9996 (n=6) and the relative standard deviation was (0.74-1.00)% .
The two methods were applied successfully to determine the content of R-HCl in pharmaceutical preparations with a recovery of 97-99 % .
