Pharmaceutical consultation as a tool to improve health outcomes for patients with type 2 diabetes

Braz. j. pharm. sci; 49 (1), 2013
This study develops and evaluates a pharmaceutical consultation program (PCP) to improve treatment for Type 2 diabetes patients (T2DP) and reduce risk factors for diabetic complications with possible application in other chronic diseases. We recruited T2DP receiving conventional medical treatment but wit...

Development and validation of an HPLC method for the determination of fluorouracil in polymeric nanoparticles

Braz. j. pharm. sci; 49 (1), 2013
The objective of this work was to develop and validate a rapid high performance liquid chromatography (HPLC) method for the quantitative analysis of fluorouracil (5-FU) in polymeric nanoparticles. Chromatographic analyses were performed on an RP C18 column with a mobile phase consisting of acetonitrile a...

A validated stability indicating HPLC method for the determination of process-related impurities in pantoprazole bulk drug and formulations

Braz. j. pharm. sci; 49 (1), 2013
A stability-indicating high-performance liquid chromatographic (HPLC) method was developed with short run time and validated for the assay of process related impurities of pantoprazole in bulk form. Resolution of drug, its potential impurities and degradation products were achieved on a Hypersil ODS colu...

Urinary excretion of L-carnitine, acetyl-L-carnitine, propionyl-L-carnitine and their antioxidant activities after single dose administration of L-carnitine in healthy subjects

Braz. j. pharm. sci; 49 (1), 2013
The urine excretion of L-carnitine (LC), acetyl-L-carnitine (ALC) and propionyl-Lcarnitine (PLC) and their relations with the antioxidant activities are presently unknown. Liquid L-carnitine (2.0 g) was administered orally as a single dose in 12 healthy subjects. Urine concentrations of LC, ALC and PLC w...

Simultaneous RP-HPLC determination of sparfloxacin and dexamethasone in pharmaceutical formulations

Braz. j. pharm. sci; 49 (2), 2013
The present study describes the development and subsequent validation of simple and accurate stability indicating RP-HPLC method for the determination of sparfloxacin and dexamethasone in pharmaceutical formulations in the presence of their stress-induced degradation products. Both the drugs and their st...

In vitro dissolution kinetic for mycophenolic acid derivatives tablets

Braz. j. pharm. sci; 49 (2), 2013
Mycophenolate mofetil (MMF) and mycophenolate sodium (MPS) are an ester and a salt of mycophenolic acid. They have different kinetic in vivo characteristics due to differences in molecular structures, physicochemical properties and formulations administered. In this study, dissolution profiles of referen...

RP-HPLC method development and validation for estimation of rivaroxaban in pharmaceutical dosage forms

Braz. j. pharm. sci; 49 (2), 2013
Rivaroxaban, an anti-clotting medication, acts at a crucial point in the blood-clotting process and stops the formation of blood clots. In this study, RP-HPLC method was developed for the determination of rivaroxaban in tablets (Xarelto® (10 mg)). Phenomenex Luna 5 µm C18 100 Å LC Column (250 x 4.6 mm...

Comparison of dissolution profile of extended-release oral dosage forms - two one-sided equivalence test

Braz. j. pharm. sci; 49 (2), 2013
The aim of this work is to present the two one-sided test (TOST) as an alternative approach to compare dissolution profiles of extended-release dosage forms. The dissolution profiles of oxycodone extended-release tablets containing 10 mg, 20 mg and 40 mg (reference and generic) were evaluated according t...

Development and stability assessment of liquid paediatric formulations containing sildenafil citrate

Braz. j. pharm. sci; 49 (2), 2013
The purpose of this study is to develop and improve oral liquids formulations of sildenafil citrate for paediatric use. Four different formulations were developed, which are as follows: two aqueous solutions of sildenafil citrate (2.5 mg/mL), with or without preservatives, and two other solutions of sild...

Pharmacokinetic study of isoquercitrin in rat plasma after intravenous administration at three different doses

Braz. j. pharm. sci; 49 (3), 2013
The aim of this study is to develop a simple and specific HPLC method using vitexin as the internal standard to investigate the pharmacokinetics of isoquercitrin (ISOQ) after three different doses administrated intravenously to rats. The pharmacokinetic parameters were calculated by both compartmental an...
