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(More)
In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of bosentan at platinum(More)
Adrenaline, which is released from the adrenal medulla, is an important compound in the reaction of sympathetic nerve system. This hormone can increase the body’s normal metabolic rate up to 100 %, and thus improves the effectiveness of the whole body. It has been considered to be involved in the control of inflammation. Therefore, we investigated whether(More)
The rapid and sensitive UV spectrophotometric method was described for the determination of etodolac, non-steroidal anti-inflammatory drugs. The type of solvent, the range of wavelength and the range of concentration were chosen in order to optimize the conditions. The developed and validated method was successfully applied to the analysis of etodolac(More)
The forced degradation study of lidocaine HCl was carried out according to the ICH guideline Q1A (R2). The degradation conditions were assessed to be hydrolysis, oxidation, photolysis and dry heat during 24 h, 48 h and 72 h and then the samples were investigated by GC-FID method and nuclear magnetic resonance (NMR) spectroscopy. According to these results,(More)
