High-performance liquid chromatography (HPLC) assay for ribavirin and comparison of the HPLC assay with radioimmunoassay.
The use of high-performance liquid chromatography (HPLC) to measure ribavirin in serum and other biological fluids has been limited by endogenous interfering substances. We report an HPLC procedure based on the extraction of ribavirin from serum, plasma, or cerebrospinal fluid with a boronate affinity gel, which uses a 3-methylcytidine internal standard. This assay is sensitive (to 0.4 microM),...
متن کاملStability-indicating HPLC Assay Method and Degradation Profile of Tamsulosin
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...
متن کاملStability Indicating HPLC Method for the Determination of Fulvestrant in Pharmaceutical Formulation in Comparison with Linear Sweep Voltammetric Method
This paper describes two rapid, sensitive and specific methods for the determination of fulvestrant in pharmaceutical preparations by high performance liquid chromatography (HPLC) and linear sweep voltammetry (LSV). HPLC method was used to study the degradation behaviour. Fulvestrant was subjected to degradation under the conditions of hydrolysis (acid and alkali), oxidation (30% H2O2). The lin...
