Stability-indicating spectrofluorimetric method with enhanced sensitivity for determination of vancomycin hydrochloride in pharmaceuticals and spiked human plasma: Application to degradation kinetics.

Journal of food and drug analysis
Based on investigating the relative fluorescence intensity of vancomycin hydrochloride (VCM) in methanol, a simple, highly sensitive, time-saving and specific spectrofluorimetric method was developed and validated. VCM fluorescence was measured at 33...

STABILITY INDICATIVE HPLC DETERMINATION OF RELATED SUBSTANCES AND IDENTIFICATION OF POTENTIAL DEGRADANTS USING LC-MS IN TRIPLE COMBINATION ANTIRETROVIRAL TABLETS.

Acta poloniae pharmaceutica
A rapid stability indicating liquid chromatography method was developed and validated for the simultaneous quantitation of related substances of antiretrovirals in combined oral dosage formulation. Separation was achieved using a Waters, Xterra RP-18...

STABILITY-INDICATING HPLC METHOD FOR DETERMINATION OF VANCOMYCIN HYDROCHLORIDE IN THE PHARMACEUTICAL DOSAGE FORMS.

Acta poloniae pharmaceutica
A simple, rapid and selective RP-HPLC method was developed for the determination of vancomycin hydrochloride. The separation was achieved using a Capital C8-Optimal column (250 x 4.6 mm i.d., 5 μm particle size) with a mobile phase composed of buffer...

Caspofungin infusion solutions (50 mg/100 mL): chemical stability and antifungal activity against Candida spp.

Die Pharmazie
BACKGROUND: Ready to use caspofungin infusion bags are centrally prepared in the Hospital Pharmacy, University Hospital of Heidelberg, for economic reasons and possibly occurring problems with drug shortages. The aim of this study was a quality contr...

The use of experimental design for the development of a capillary zone electrophoresis method for the quantitation of captopril.

Die Pharmazie
A capillary zone electrophoresis (CZE) method for the quantitation of captopril (CPT) using UV detection was developed. Influence of electrolyte concentration and system variables on electrophoretic separation was evaluated and a central composite de...

Development and validation of an LC-MS/MS method for quantification of NC-8 in rat plasma and its application to pharmacokinetic studies.

Journal of food and drug analysis
ent-16-Oxobeyeran-19-N-methylureido (NC-8) is a recently synthesized derivative of isosteviol that showed anti-hepatitis B virus (HBV) activity by disturbing replication and gene expression of the HBV and by inhibiting the host toll-like receptor 2/n...

Determination of IMM-H004 and its active glucuronide metabolite in rat plasma and Ringer's solution by ultra-performance liquid chromatography-tandem mass spectrometry.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences
IMM-H004 is a novel neuroprotective agent and its glucuronide metabolite IMM-H004G has similar protective effects against cerebral ischemic injury in vivo and in vitro. A specific and sensitive ultra-performance liquid chromatography-tandem mass spec...

Improving Dissolution Rate of Carbamazepine-Glutaric Acid Cocrystal Through Solubilization by Excess Coformer.

Pharmaceutical research
PURPOSE: The use of soluble cocrystals is a promising strategy for delivering poorly soluble drugs. However, precipitation of poorly soluble crystal form during dissolution hinders the successful tablet development of cocrystals. This work was aimed ...

Stability of infliximab solutions in different temperature and dilution conditions.

Journal of pharmaceutical and biomedical analysis
Infliximab is a monoclonal antibody widely used for the treatment of inflammatory diseases. Over the past few years, many studies have assessed that monoclonal antibodies are prone to aggregation under stress conditions. The aim of this study was to ...

Stability of sodium bicarbonate injection 8.4% in syringes over a six-week period in refrigerated temperature.

Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners
Background Dysfunctional central venous catheter prohibits the administration of potential life-saving chemotherapy and the delivery of essential supportive care needs to patients. Sodium bicarbonate injection has been shown to impede against fibrin ...
