Flurbiprofen which is a non-steroidal anti-inflammatory drug (NSAID), has been safely used for the control of postoperative patient's morbidity after periodontal plastic surgeries requiring palatal graft harvesting, but there is little information on the efficacy of topical use. The aim of the study was to evaluate whether patient pain perception was reduced and patient morbidity was improved by using oral spray of flurbiprofen after palatal graft harvesting.
Flurbiprofen, a hydrophobic COX inhibitor, was coordinated axially with oxoplatin to form a new conjugate cis, cis, trans-[Pt(IV)(NH3)2Cl2(flurbiprofen)2]. The successful synthsis of this new conjugate was confirmed by 1H, 13C and 195Pt NMR. The potential of this conjugate being reduced to cisplatin and subsequently exerting its DNA cross-linking ability was verified using cyclic voltammetry (CV), HPLC and mass spectrum (MS). This conjugate showed markedly higher cytotoxicity on many cancer cell lines than ...
Problems like postoperative pain are still common phenomena after general anesthesia. Oxycodone hydrochloride is a semisynthetic opioid with a safe and excellent therapeutic effect on visceral pain. Flurbiprofen axetil has the efficacy of targeted analgesia. We hypothesize that different doses of oxycodone hydrochloride combined with flurbiprofen axetil would generate great results on postoperative intravenous analgesia in lower abdominal patients.
Tribo-electrification is a common occurrence within the pharmaceutical industry where solid dosage forms constitute majority of pharmaceutical formulations. Tribo-electrification of powders leads to a range of complications such as adhesion of particulate material to the processing equipment resulting in segregation, affecting the content uniformity. Flurbiprofen, a highly charging material, was used as a model drug to investigate the tribo-electrification and adhesion characteristics by impregnating the mo...
In this study, a bi-layer osmotic pump tablet (OPT) of Flurbiprofen (FP) solid dispersions (SDs) was developed to increase the solubility of the poorly soluble drug and control drug release at a constant rate. Based on the thermodynamic properties investigation of the drug, the carrier and the calculation of the solubility parameters, the FP-SD was prepared by hot melt extrusion (HME) technique with the carrier of PVPVA64. Then central composite design-response surface methodology (CCD-RSM) was used to eval...
The objectives of this study were to explore inter-study heterogeneity in the pharmacokinetics (PK) of orally administered rifampicin, to derive summary estimates of rifampicin PK parameters at standard dosages and to compare these with summary estimates for higher dosages.
This prospective clinical study was carried out to evaluate the analgesic efficacy and safety of oral spray form of flurpiprofen in the treatment of postoperative pain in tonsillectomy patients.
Flurbiprofen (FB) is the one of the non-steroidal anti-inflammatory drugs (NSAIDs) which has low water solubility and dissolution. Nanosuspensions are promising drug delivery systems consisting pure drug particles to overcome poor water solubility issues. Recently, design of experiment (DoE) approaches have often been used to develop new formulations include nanosuspensions. The main objective of this study was to prepare FB nanosuspensions in existence of Plantacare 2000 (PL) as stabilizer using DoE approa...
The pharmacokinetics (PK) of β-lactam antibiotics in cystic fibrosis (CF) patients has been compared with that in healthy volunteers for over four decades; however, no quantitative models exist that explain the PK differences between CF patients and healthy volunteers in older and newer studies. Our aims were to critically evaluate these studies and explain the PK differences between CF patients and healthy volunteers. We reviewed all 16 studies that compared the PK of β-lactams between CF patients and h...
The aim of this study was to assess the pharmacokinetics (PK) and safety/tolerability of siponimod in healthy subjects when coadministered with (1) the moderate cytochrome P450 (CYP) 2C9 and CYP3A inhibitor fluconazole (Study A), and (2) with three different CYP2C9 genotype variants (Study B).
Understanding the pharmacokinetics in cystic fibrosis (CF) patients is important for dosing. For antibiotics with extensive metabolism, however, a comparison of metabolite formation and elimination between CF-patients and healthy volunteers has never been performed via population modeling. We aimed to compare the population pharmacokinetics of fleroxacin and its N‑oxide and demethyl metabolites between CF-patients and healthy volunteers. Our analysis included eleven adult CF-patients and twelve healthy vo...
Magnetic solid-phase extraction based on FeO/graphene nanocomposites for enantioselective determination of representative profens in the environmental water samples and molecular docking study on adsorption mechanism of graphene.
In this work, a nanocomposite, FeO/graphene was prepared and characterized. Five profens (including ibuprofen, flurbiprofen, pranoprofen, indoprofen and loxoprofen sodium) were extracted from three environmental water samples by using the synthetic FeO/graphene, followed by simultaneous determination of the enantiomers on a Chiralcel OJ-RH column coupled with a triple quadrupole mass spectrometry. Factors affecting the extraction efficiency, such as amount of adsorbents, solution pH, ionic strength, type an...
: We assessed the effect of fluconazole 1200 mg/day on QT interval in cryptococcal meningitis patients. Mean QTc change from baseline to day 7 was 10.1ms (IQR: -28 to 46) in the fluconazole treatment group and -12.6ms (IQR: -39 to 13.5) in those not taking fluconazole (p = 0.04). No significant increase in QTc measurements over 500ms was observed with fluconazole. Nevertheless, it remains important to correct any electrolyte imbalance and avoid concomitant drugs that may increase QTc.
The objective of this study was to evaluate the electrocardiographic effects of hawthorn in healthy adult volunteers. It was double-blind cross-over trial randomized 20 healthy adult volunteers to receive either a single oral 160-mg dose of hawthorn or matching placebo. Triplicate 12-lead electrocardiograms were taken before treatment and at 1-, 2-, 4-, and 6-hr post-dose. Following at least a 7-day washout period, participants were crossed over to the opposing treatment arm and had the measurements repeate...
Regorafenib is a multi-kinase inhibitor under investigation for use in neovascular age-related macular degeneration. In this Phase I study, regorafenib eye drops were administered to healthy volunteers to provide information on safety, tolerability and systemic exposure.
The aim of this study was to explore the pharmacokinetic-pharmacodynamic (PK-PD) relationship of metformin on glucose levels after the administration of 250 mg and 1000 mg of metformin in healthy volunteers.
Alpha-2 agonists are direct peripheral vasoconstrictors by activation of vascular smooth muscle alpha-2 adrenoceptors. The impact of this response during dexmedetomidine infusion remains poorly quantified. Our goal was to investigate the pharmacokinetic (PK) and pharmacodynamic (PD, vasoconstriction) effects of a computer controlled dexmedetomidine infusion in healthy volunteers.
Nintedanib is a substrate for p-glycoprotein which can impact bioavailability. We investigated the effects of ketoconazole, a p-glycoprotein inhibitor, and rifampicin, a p-glycoprotein inducer, on the pharmacokinetics of nintedanib.
Epidemiological data suggest that non-steroidal anti-inflammatory drugs (NSAIDs) may protect against Alzheimer's disease (AD). Unfortunately, recent trials have failed in providing compelling evidence of neuroprotection. Discussion as to why NSAIDs effectivity is uncertain is ongoing. Possible explanations include the view that NSAIDs and other possible disease-modifying drugs should be provided before the patients develop symptoms of AD or cognitive decline. In addition, NSAID targets for neuroprotection a...
A simple, accurate and sensitive micro UHPLC-MS/MS method was developed and validated for the simultaneous determination of 10 nonsteroidal anti-inflammatory drugs (NSAIDs) from different environmental matrices. The micro LC ‒ on-line SPE method described in this study allowed to determine the selected drugs at ultra-trace levels without the most commonly used complex off-line SPE sample preparation procedures. The presented method is capable of reaching satisfactory low LOQ values with analysing the samp...
Rifampicin exerts significant brain protective functions in multiple experimental models. Here we summarized the underlying mechanisms of the neuroprotective and pro-cognitive effects of rifampicin that is mediated by its anti-inflammatory, anti-tau, anti-amyloid and cholinergic effects. Beyond suggesting that rifampicin shows strong brain protective effects in preclinical models of Alzheimer's Disease we also have provided substantial clinical evidence for the neuroprotective and pro-cognitive effects of r...
Fluconazole is the most commonly used antifungal agent for both the treatment of cryptococcal meningitis, and for prophylaxis against the disease. However, its prolonged use has the potential to exert selection pressure in favour of fluconazole-resistant strains. We evaluated the prevalence of fluconazole resistance of Cryptococcus spp. clinical isolates in 29 studies from 1988 to May 2017 included in EMBASE and MEDLINE databases. A total of 4,995 Cryptococcus isolates from 3,210 patients constituted this s...
Population Pharmacokinetic Modeling to Describe the Total Plasma and Free Brain Levels of Fluconazole in Healthy and Cryptococcus neoformans Infected Rats: How Does the Infection Impact the Drug's Levels on Biophase?
The present work aimed to evaluate the influence of experimental meningitis caused by C. neoformans on total plasma and free brain concentrations of fluconazole (FLC) in Wistar rats.
Citric acid has been used for over six decades to induce cough; however the mechanism of its pro-tussive effect is still not fully understood. We assessed the response to inhalation of citric acid at varying levels of acidity to determine if the pH of the solution plays a role in the induction of cough. Data was collected from both healthy volunteers and patients with chronic cough.
Our objective was to develop population pharmacokinetic (PK) models for ceftazidime and avibactam in the plasma and epithelial lining fluid (ELF) of healthy volunteers and to compare ELF concentrations to plasma PK/pharmacodynamic (PD) targets.
