The aim of this study was to formulate and characterize Eudragit® L100 and Eudragit® L100-poly(lactic-co-glycolic acid) (PLGA) nanoparticles containing diclofenac sodium. Diclofenac generates severe adverse effects with risks of toxicity. Thus, nanoparticles were prepared to reduce these drawbacks in the present study. These nanoparticles were evaluated for(More)
The aim of the present study was to develop and characterize metformin HCl-loaded nanoparticle formulations. Nanoparticles were prepared by the nanoprecipitation method using both a single polymer (Eudragit(®)RSPO) and a polymer mixture (Eudragit/PLGA). The mean particle size ranged from 268.8 to 288 nm and the nanoparticle surface was positively charged(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)
Boron and its derivatives are effective in bone recovery and osteointegration. However, increasing the boron levels in body liquids may cause toxicity. The aim of our study is to investigate serum boron levels using ICP-MS after implantation of different ratios of nano-hBN-HA composites in rat femurs. All rats were (n=126) divided into five experimental(More)
A rapid, simple and sensitive UFLC-MS/MS method was developed and validated for the determination of bosentan in rat plasma using etodolac as an internal standard (IS) after liquid-liquid extraction with diethyl ether-chloroform (4:1, v/v). Bosentan and IS were detected using electrospray ionization in positive ion multiple reaction monitoring mode by(More)
The accurate determination of prilocaine HCl levels in plasma is important in both clinical and pharmacological/toxicological studies. Prilocaine HCl is quickly hydrolyzed to o-toluidine, causing methemoglobinemia. For this, the present work describes the methodology and validation of a GC-MS assay for determination of prilocaine HCl with lidocaine HCl as(More)
Thymus praecox ssp. grossheimii (RONNIGER) JALAS var. grossheimii (Lamiaceae) is used as an herbal tea for cold, stomachache, cough, and infections in Turkey. There are no phytochemical studies on this species. We performed phytochemical studies and quantitative analysis of rosmarinic acid and luteolin 5-O-β-D-glucopyranoside in the methanol extract of the(More)
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)
A simple and sensitive spectrophotometric method was developed for the determination of prilocaine HCl in pharmaceutical preparation and human plasma. The quantitative analysis of prilocaine HCl was carried out using of wavelength at 230 nm. The method was linear in concentration range of 3-15 μg/mL for standard solution and 4-15 μg/mL for human plasma.(More)
