The present study describes the development of a validated RP-HPLC method for the determination of 5-fluorouracil in presence of its degradation products or other pharmaceutical excipients. Stress studies were performed on 5-fluorouracil and it was found that it degrades sufficiently in alkaline conditions, while negligible degradation was observed in acidic, neutral, oxidative and photolytic c...

A simple, sensitive, stability-indicating HPLC method was developed and validated for the quantitative determination of nalbuphine hydrochloride in presence of its degradation product.The analysis was carried out on a BDS Hypersil C18 ( 250 X 4.6 X 5μm particle size) using a mobile phase consisting of 5 mM sodium acetate buffer; pH 5.5: acetonitrile (40:60, v/v). The analysis was performed at a...

A novel stability-indicating reverse-phase high-performance liquid chromatographic (HPLC) method has been developed for quantitative determination of Fosamprenavir Calcium, HIV-1 protease inhibitor. Chromatographic separation was achieved using an YMC Pack ODS AQ (150 mm × 4.6 mm × 3.0 μm) HPLC column in isocratic mode employing 0.05 M Potassium dihydrogen orthophosphate monohydrate (pH 6.8) bu...

The stability-indicating LC assay method was developed and validated for quantitative determination of cefcapene pivoxil in the presence of degradation products formed during forced degradation studies. An isocratic RP-HPLC method was developed with a Lichrospher RP-18 (250 mm × 4.6 mm, 5 μm) column and the mobile phase composed of 45 volumes of acetonitrile and 55 volumes of mixture composed o...

A novel stability-indicating reversed-phase high-performance liquid chromatographic (HPLC) method has been developed for the quantitative determination of darunavir ethanolate, an HIV-1 protease inhibitor. The chromatographic separation was achieved using an X-Bridge C18 (150 × 4.6 mm × 3.5 µm) HPLC column in isocratic mode employing 0.01M ammonium formate (pH.3.0) buffer and acetonitrile in th...

A sensitive, stability-indicating liquid-chromatographic method for analysis of tamsulosin in the presence of its degradation products has been developed and validated. Efficient chromatographic separation was achieved on a C18 column with a simple isocratic mobile phase consisting methanol: 50 mM phosphate buffer (pH 7.8, ratio 80:20) at a flow rate of 1 ml/m. The linearity of the method was e...

The present paper describes stability indicating reverse phase Ultra performance liquid chromatographic (RPLC) assay method for Atrovastatin Calcium in bulk drugs. The developed method is also applicable for the related substance determination and degradation products generated from forced decomposition studies. The drug substance was subjected to stress conditions of acid hydrolysis, base hydr...

Two simple, accurate, and sensitive methods were developed for the determination of netobimin in the presence of its degradation product. Method (A) was an HPLC method, performed on C18 column using acetonitrile/methanol/0.01 M potassium dihydrogen phosphate (56 : 14 : 30 by volume) as a mobile phase with a flow rate of 0.5 mL/min. Detection was performed at 254 nm. Method (B) was a TLC method,...

A simple, sensitive, inexpensive, and rapid stability indicating high performance liquid chromatographic method has been developed for determination of gemcitabine in injectable dosage forms using theophylline as internal standard. Chromatographic separation was achieved on a Phenomenex Luna C-18 column (250 mm × 4.6 mm; 5μ) with a mobile phase consisting of 90% water and 10% acetonitrile (pH 7...

A stability-indicating liquid chromatographic (LC) method was developed for the determination of posaconazole in bulk. Chromatographic separation was achieved using an isocratic elution in a reversed-phase system, with a mobile phase composed of methanol-water (75:25, v/v), at 1.0 mL min(-1) flow. Samples were exposed to degradation under thermal, oxidative and acid/basic conditions, and no int...
