REVIEW
Ka Ting Ng, Aslinah Velayit, Delton Kah Yeang Khoo, Amirah Mohd Ismail, Marzida Mansor
OBJECTIVE: Fluid overload is a common phenomenon seen in intensive care units (ICUs). However, there is no general consensus on whether continuous or bolus furosemide is safer or more effective in these hemodynamically unstable ICU patients. The aim of this meta-analysis was to examine the clinical outcomes of continuous versus bolus furosemide in a critically ill population in ICUs. DATA SOURCES: MEDLINE, EMBASE, PubMed, and the Cochrane Database of Systematic reviews were searched from their inception until June 2017...

OBJECTIVE: We reviewed the safety of nuclear diuretic renography with furosemide in patients with sulfonamide allergies. The electronic health record was used to uncover any drug effects reported within 30 days of diuretic renograms performed between January 2009 and December 2015. CONCLUSION: Eighty-three of 1103 (7.5%) diuretic renograms were performed on patients with sulfonamide allergies. Two instances of minor rash occurred. No serious reactions occurred. Furosemide is associated with an extremely low risk of minor reactions in patients with sulfonamide allergies...

The purpose of this research was to develop and prepare orally disintegrating tablets (ODTs) containing furosemide by direct compression method. Furosemide, microcrystalline cellulose (MCC), low-substituted hydroxypropylcellulose LH-11 (L-HPC), aspartame, sodium stearyl fumarate were used for ODT formulation. MCC and L-HPC were used in ratios of 1:9 (ODT1) and 1:4 (ODT2). The results of the quality control parameters obtained for bulk powders (angle of repose, compressibility index, Hausner ratio, bulk density and volume, apparent density and volume, swelling of superdisintegrants and powder moisture) were taken as an indication of good compressibility of tablets...

RATIONALE: Drug discovery studies invariably require qualitative and quantitative analyses of target compounds at every stage of drug discovery. We have developed a system combining molecular interaction analysis and mass spectrometry (LC-MS) using the principle of nano pore optical interferometry (nPOI) called molecular interaction kinetics-mass spectrometry (MIK-MS). Since nPOI has high binding capacity, the bond-dissociated compound can be directly detected using LC-MS. In this study, we use carbonic anhydrase (CA) II as a ligand and apply six small compounds as analytes and report the affinity analysis using MIK-MS...

BACKGROUND DRESS is a rare, life threatening syndrome that occurs following exposure to certain medications, most commonly antibiotics and antiepileptics. While sulfonamide antibiotics are frequently implicated as causative agents for DRESS syndrome, furosemide, a nonantibiotic sulfonamide, has not been routinely reported as the causative agent despite its widespread use. CASE REPORT A 63 year old male who started furosemide for lower extremity edema 10 weeks prior presented with diarrhea, fever of 39.4°C, dry cough and maculopapular rash involving >50% of his body...

BACKGROUND: Resistant hypertension is characterized when the blood pressure (BP) remains above the recommended goal after taking three antihypertensive drugs with synergistic actions at their maximum recommended tolerated doses, preferably including a diuretic. Identifying the contribution of intravascular volume and serum renin in maintaining BP levels could help tailor more effective hypertension treatment, whether acting on the control of intravascular volume or sodium balance, or acting on the effects of the renin-angiotensin-aldosterone system (RAAS) on the kidney...

Tipranavir (TPV) is one of the most recently developed protease inhibitors (PI) and it is specially recommended for treatment-experienced patients who are resistant to other PI drugs. In this work, a simple and friendly environmental CZE stability-indicating method to assay TPV capsules was developed and two TPV organic impurities were identified by high resolution mass spectrometry (HRMS). The optimized analytical conditions were: background electrolyte composed of sodium borate 50mM, pH 9.0 and 5% of methanol; voltage + 28kV; hydrodynamic injection of 5s (100mbar), detection wavelength 240nm, at 25°C...

Parameter sensitivity and uncertainty analysis for physiologically based pharmacokinetic (PBPK) models are becoming an important consideration for regulatory submissions, requiring further evaluation to establish the need for global sensitivity analysis. To demonstrate the benefits of an extensive analysis, global sensitivity was implemented for the GastroPlus™ model, a well-known commercially available platform, using four example drugs: acetaminophen, risperidone, atenolol, and furosemide. The capabilities of GastroPlus were expanded by developing an integrated framework to automate the GastroPlus graphical user interface with AutoIt and for execution of the sensitivity analysis in MATLAB®...

BACKGROUND: Recent studies demonstrate that interstitial inorganic phosphate is significantly elevated in the breast cancer microenvironment as compared to normal tissue. In addition it has been shown that breast cancer cells express high levels of the NaPi-IIb carrier (SLC34A2), suggesting that this carrier may play a role in breast cancer progression. However, the biochemical behavior of inorganic phosphate (Pi) transporter in this cancer type remains elusive. METHODS: In this work, we characterize the kinetic parameters of Pi transport in the aggressive human breast cancer cell line, MDA-MB-231, and correlated Pi transport with cell migration and adhesion...

With no lysine kinase 4 (WNK4) is essential to activate the thiazide-sensitive NaCl cotransporter (NCC) along the distal convoluted tubule, an effect central to the phenotype of familial hyperkalemic hypertension. Although effects on potassium and sodium channels along the connecting and collecting tubules have also been documented, WNK4 is typically believed to have little role in modulating sodium chloride reabsorption along the thick ascending limb of the loop of Henle. Yet wnk4-/- mice (knockout mice lacking WNK4) do not demonstrate the hypocalciuria typical of pure distal convoluted tubule dysfunction...

BACKGROUND: Admission for diuresis remains a common and costly event in patients with advanced heart failure (HF). We tested whether spot urine sodium could identify patients likely to respond to ambulatory diuretic infusion without hospitalization. METHODS AND RESULTS: We prospectively followed 176 consecutive patients with advanced heart failure receiving intravenous furosemide for congestion in an ambulatory clinic. Spot urine sodium was measured in first voided urine after diuretic infusion and compared with 3-hour urine output and subsequent risk of 30-day hospitalization or emergency department (ED) visit...

BACKGROUND: Lower urinary sodium concentration (UNa) may reflect impaired renal perfusion, higher neurohormonal activity and diuretic resistance. However, the prognostic impact of UNa in patients with acute heart failure (AHF) has not been fully elucidated. METHODS: We investigate the association between UNa and clinical outcomes in 669 patients admitted with AHF in our prospective registry. Patients were stratified into tertiles based on UNa in a spot urine sample on admission...

BACKGROUND: Fluid management is a major factor determining perioperative outcome, yet in reality, fluid administration practice is variable. Thirst however, is a highly sensitive and reliable indicator of fluid deficits. We explored the use of thirst sensation to trigger i.v. fluid boluses to guide individualized fluid management. METHODS: We performed a randomised double crossover trial on 16 healthy male volunteers, of mean age 31 yr and BMI 24.4 kg m-2. Twice, after administrations of oral furosemide (40 mg) and 12 h of oral fluid restriction, participants received a 4-h i...

The cell-penetrating peptide GV1001 has been investigated as an anticancer agent and recently demonstrated anti-oxidant and anti-inflammatory effects. It has shown a protective effect on a kanamycin (KM)-induced ototoxicity mouse model. In the present study, we administered GV1001 at different time points after inducing hair cell damage, and examined if it rescues hair cell loss and restores hearing. A deaf mouse model was created by intraperitoneal injection of KM and furosemide. First, to test the early temporal change of hearing and extent of hair cell damage after KM and furosemide injection, hearing and outer hair cells (OHCs) morphology were evaluated on day 1, day 2 and day 3 after injection...

It is unknown whether a response to tolvaptan (TLV) is related to prognosis in patients with acute decompensated heart failure (ADHF). We selected 25 patients as responders by their urinary response to TLV and by reduction of loop diuretics from 37 consecutive ADHF patients treated with TLV. As a control group, we selected 25 patients from 100 consecutive ADHF patients who were not treated with TLV by propensity score matching for age, serum sodium level, serum creatinine level, plasma B-type natriuretic peptide (BNP) level, systolic blood pressure, heart rate, and dose of loop diuretics...

We investigated the effects of the addition of two coagulants-polyaluminium chloride (PACl) and chitosan-into the membrane bioreactor (MBR) process on membrane fouling and the removal of pharmaceuticals and personal care products (PPCPs). Their addition at optimized dosages improved the permeability of the membrane by reducing the concentration of soluble microbial products in mixed liquor, the content of inorganic elements, and irreversible fouling of the membrane surface. During long-term operation, the addition of PACl increased removal efficiencies of tetracycline, mefenamic acid, atenolol, furosemide, ketoprofen, and diclofenac by 17-23%...
