In this research two analytical methods were developed for the determination of Azelastin as raw material and in Nasal Spray formulation. The first method was spectrophotometric while the other used the technic of HPLC The first method based on measuring the absorbance at λmax 284 nm . The relationship between the absorbance and the concentration is rectilinear over the range 0.001 – 0.008 g %. The proposed spectrophotometric method was successfully applied to the determination of Azelastin in nasal spray. The percentage recoveries were 99.378±1 (10 duplicate readings)1 No interference was noticed from co-formulated drugs. For the absorbance at λmax the obtained results were in good agreement with which obtained by the Pharmacopeia method. The substance gave a good separation while the retention time was 1.467 min.

Research summary
في هذا البحث، تم تطوير طريقتين تحليليتين لتحديد مادة الأزيلاستين بوصفها مادة أولية وفي أشكالها الصيدلانية كبخاخ أنفي. الطريقة الأولى تعتمد على تقنية الطيف الضوئي، حيث تم قياس الامتصاص عند طول موجة الامتصاص الأعظمي 284 نانومتر. أظهرت النتائج علاقة طردية بين الامتصاص والتركيز ضمن المجال 0.001 - 0.008 غ%. تم تطبيق هذه الطريقة بنجاح على بخاخ الأنف، وكانت نسبة المردود 99.378 ± 1.1%. لم تؤثر السواغات الداخلية في المستحضرات على امتصاص المادة عند طول موجتها الأعظمية. الطريقة الثانية تعتمد على تقنية الاستشراب السائل عالي الأداء (HPLC) باستخدام عمود فصل ODS (C18) بطول 25 سم وقطر 4.6 ملم، وطور متحرك من الأسيتونتريل مع وقاء فوسفاتي بنسبة 1:1. أظهرت المادة فصلاً جيداً وزمن احتباس 1.467 دقيقة. تم التحقق من دقة ومصداقية الطريقتين مقارنة بالطريقة الدستورية.
Critical review
دراسة نقدية: يعتبر البحث ذو أهمية كبيرة في مجال التحليل الصيدلاني، حيث يقدم طرقاً دقيقة وموثوقة لمعايرة الأزيلاستين في أشكاله الصيدلانية. ومع ذلك، يمكن أن تكون هناك بعض النقاط التي تحتاج إلى تحسين. على سبيل المثال، قد يكون من المفيد توسيع نطاق الدراسة لتشمل أشكال صيدلانية أخرى غير البخاخ الأنفي. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لمزيد من الدراسات للتحقق من تأثير العوامل البيئية المختلفة على دقة وموثوقية الطريقتين. كما يمكن أن يكون من المفيد تقديم مقارنة أكثر تفصيلاً بين الطريقتين المطورتين والطريقة الدستورية من حيث التكلفة والوقت والكفاءة.

New, accurate, sensitive and reliable kinetic spectrophotometric method for the assay of fluvastatin sodium (FVS) in pure form and capsules has been developed. The method involves the oxidative coupling reaction of FVS with 3-methyl-2-benzothiazolinone hydrazone hydrochloride monohydrate (MBTH) in the presence of Ce(IV) in an acidic medium to form colored product with lambdamax at 615 nm.
Terfenadine reacts with mixed anhydriedes (Malonic and acetic anhydrides) producing a yellow-coulored product with intense fluorescence. Based on this fact, a spectrophotometric method was developed for the determination of terfendaine in dosage f orms. The relation between the absorbance at 395 nm and the concentration is rectilinear over the range 0.5-5 μg.ml-1. The reaction product was also measured spectrofluorimetrically at 435 nm after excitation at 395 nm. The fluorescence intensity was directly proportional to the concentration over the range 0.5-4 ng.ml-1. The different parameters affecting the development and stability of the reaction product were carefully studied and incorporated into the procedure. The proposed spectrophotometric method was successfully applied to the determination of terfenadine in tablets and suspensions; the % recoveries were 99.83 ± 0.75 and 99.65 ± 0.83, respectively. The proposed spectrofluorimetric method was applied to the determination of terfenadine in spiked human plasma. the % recovery was 99.35 ± 2.19. The method is highly sensitive and specific. No interference was noticed from co-formulated drugs, such as pseudoephedrine and ibuprofen.
The present study describes a simple stability-indicating reversed-phase HPLC assay for pentoxifylline in its pharmaceutical dosage forms. Separation of the drug and the degradation products، under stress conditions was successfully achieved on a C 18 column utilizing water: MeOH (60:40 v/v)، pumped at a flow rate of 1 ml min-1 with UV detection at 272 nm. The retention time of pentoxifylline was about 14 min. The method was satisfactorily validated with respect to linearity، precision، accuracy and selectivity. The response was linear in the range of 0.6-3.5 μg/ml with R2 0.994. The method was accurate (recovery 100.1%) and precise (RSD < 2%). Detection and quantification limit were 0.2 μg/ml and 0.4 μg/ml respectively. The suggested method was successfully applied for the analysis of pentoxifylline in extended release tablets available in Syrian market.
A simple and accurate method was developed for the analysis of carbinoxamine maleate, dextromethorphan hydrobromide and pseudoephedrine hydrochloride content in pure form and pharmaceutical preparations using HPLC. Analysis was conducted on a sili ca column (6 μm) with mobile phase consisting of ethanol – ammonium acetate (0.05 M) in rate [85:15] respectively, and at detection wavelength of 276 nmand flow rate 1ml/ min. Results were linear (correlation coefficient R > 0.9996) in the range of the studied concentrations for the active materials. The relative standard deviations (n=6) of intra and interday assay were 0.931%, 1.527% for carbinoxamine maleate and 0.717%, 1.058 % for dextromethorphan hydrobromide and 0.309%, 0.891% for pseudoephedrine hydrochloride, respectively. This method, proved to be easy, precise and economical, is useful for quality control of pharmaceutical drugs industrial samples.
