A chemiluminescence reagent free method for the determination of captopril in medicine and urine samples by using trivalent silver.

Journal of pharmaceutical analysis
A novel flow-injection chemiluminescence (FI-CL) method free of CL reagent was developed for the determination of captopril based on its enhancing effect on the CL derived from diperiodatoargentate(III)-sulfuric acid system. Compared with the convent...

Potential of RP-UHPLC-DAD-MS for the qualitative and quantitative analysis of sofosbuvir in film coated tablets and profiling degradants.

Journal of pharmaceutical analysis
Sofosbuvir is one of the new direct-acting antiviral drugs against hepatitis C virus (HCV) infection. This drug has recently been launched into the market, and generic versions of the medication are expected to be produced by local drug producers in ...

Chromatoprobe as a sample-sparing technique for residual solvent analysis of drug discovery candidates by gas chromatography.

Journal of pharmaceutical analysis
In drug discovery research, residual solvent measurement is an integral part of purity analysis for synthesis of a drug candidate before it is used for toxicity testing. This is usually carried out using gas chromatography (GC) with direct injection ...

Simultaneous quantification of amiloride and hydrochlorothiazide in human plasma by liquid chromatography-tandem mass spectrometry.

Journal of pharmaceutical analysis
A selective, sensitive and precise assay based on solid phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for the simultaneous determination of amiloride (AMI) and hydrochlorothiazide (HCTZ) in human plasma....

Chemical and microbiological characterization of tinctures and microcapsules loaded with Brazilian red propolis extract.

Journal of pharmaceutical analysis
The aim of this study was to characterize tinctures and microcapsules loaded with an ethanol extract of red propolis through chemical, physicochemical and microbiological assays in order to establish quality control tools for nutraceutical preparatio...

Simultaneous colorimetric determination of morphine and ibuprofen based on the aggregation of gold nanoparticles using partial least square.

Journal of pharmaceutical analysis
In this work a new method is presented for simultaneous colorimetric determination of morphine(MOR) and ibuprofen(IBU) based on the aggregation of citrate-capped gold nanoparticles (AuNPs). Citrate-capped gold nanoparticles were aggregated in the pre...

A stability-indicating LC-MS/MS method for zidovudine: Identification, characterization and toxicity prediction of two major acid degradation products.

Journal of pharmaceutical analysis
Zidvovudine (AZT) is a nucleoside analogue reverse transcriptase inhibitor (NRTI), a class of anti-retroviral drug. A stability-indicating assay method for AZT was developed in line with ICH guideline. Successful separation of AZT and its degradation...

An improved LC-MS/MS method for the quantification of alverine and para hydroxy alverine in human plasma for a bioequivalence study.

Journal of pharmaceutical analysis
A highly sensitive and selective high performance liquid chromatography-tandem mass spectrometry method was developed and validated for the quantification of alverine (ALV) and its active metabolite, para hydroxy alverine (PHA), in human plasma. For ...

Fast and sensitive LC-MS/MS method for the simultaneous determination of lisinopril and hydrochlorothiazide in human plasma.

Journal of pharmaceutical analysis
A sensitive and rapid liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed for the simultaneous determination of lisinopril (LIS) and hydrochlorothiazide (HCTZ) in human plasma using their labeled internal standards (IS...

Degradation kinetics of larotaxel and identification of its degradation products in alkaline condition.

Journal of pharmaceutical analysis
Larotaxel, a new taxane compound prepared by partial synthesis from 10-deacetyl baccatin III, is active against tumors. In this research, a selective LC-MS method was developed and validated for the study of degradation kinetics of larotaxel, which w...
