Elderly patients with cancer may have comorbidities, each requiring additional pharmacologic treatment. Therefore, the occurrence of pharmacokinetic (PK) and pharmacodynamic (PD) interactions is very likely, and the risk of adverse reactions (ADRs), due to the narrow therapeutic window of anticancer drugs, is increased. Drug-drug interactions (DDIs) may occur in prostate cancer patients due to inhibition by abiraterone of liver cytochrome P450 (CYP)-dependent enzymes CYP2C8 and 2D6, which are involved in the metabolism of approximately 25% of all drugs, and induction by enzalutamide of CYP3A4, 2C9 and 2C19, which metabolize up to 50% of medications...

Electrochemical activation of peroxydisulfate (PDS) at Ti/Pt anode was systematically investigated for the first time in this work. The synergistic effect produced from the combination of electrolysis and the addition of PDS demonstrates that PDS can be activated at Ti/Pt anode. The selective oxidation towards carbamazepine (CBZ), sulfamethoxazole (SMX), propranolol (PPL), benzoic acid (BA) rather than atrazine (ATZ) and nitrobenzene (NB) was observed in electrochemical activation of PDS process. Moreover, addition of excess methanol or tert-butanol had negligible impact on CBZ (model compound) degradation, demonstrating that neither sulfate radical (SO4(-)) nor hydroxyl radical (HO) was produced in electrochemical activation of PDS process...

Eslicarbazepine acetate (ESL) is an anticonvulsant drug approved for the treatment of focal epilepsies, and related to oxcarbazepine and carbamazepine (CBZ), which are also derivatives of the dibenzazepine family. ESL is contraindicated in patients with hypersensitivity reactions to CBZ.We report a patient with frontal lobe epilepsy responding to treatment with ESL without any serious adverse effects after developing a severe skin rash following treatment with CBZ. HLA testing revealed an HLA-A*31:01 haplotype, that increases the risk of CBZ-induced cutaneous reactions...

Oral liquids are safe alternatives to solid dosage forms, notably for elderly and pediatric patients that present dysphagia. The use of ready-to-use suspending vehicles such as SyrSpend SF PH4 is a suitable resource for pharmacists as they constitute a safe and timesaving option that has been studied often. The objective of this study was to evaluate the stability of 10 commonly used active pharmaceutical ingredients (allopurinol 20 mg/mL; amitriptyline hydrochloride 10 mg/mL; carbamazepine 25 mg/mL; domperidone 5 mg/mL; isoniazid 10 mg/mL; ketoconazole 20 mg/mL; lisinopril 1 mg/mL; naproxen 25 mg/mL; paracetamol [acetaminophen] 50 mg/mL; and sertraline hydrochloride 10 mg/mL) compounded in oral suspensions using SyrSpend SF PH4 as the vehicle throughout the study period and stored both at controlled refrigerated (2°C to 8°C) and room temperature (20°C to 25°C)...

BACKGROUND: Few studies have examined Manual Motor Speed (MMS) in bipolar disorder (BD). The aim of this longitudinal, family study was to explore whether dysfunctional MMS represents a neurocognitive endophenotype of BD. METHODS: A sample of 291 subjects, including 131 BD patients, 77 healthy first-degree relatives (BD-Rel), and 83 genetically-unrelated healthy controls (HC), was assessed with the Finger-Tapping Test (FTT) on three occasions over a 5-year period...

OBJECTIVE: To characterize self-poisoning suicide deaths in BD compared to other suicide decedents. METHODS: Extracted coroner data from all suicide deaths (n = 3319) in Toronto, Canada from 1998 to 2012. Analyses of demographics, clinical history, recent stressors, and suicide details were conducted in 5 subgroups of suicide decedents: BD self-poisoning, BD other methods, non-BD self-poisoning, non-BD other methods, and unipolar depression self-poisoning. Toxicology results for lethal and present substances were also compared between BD and non-BD self-poisoning subgroups as well as between BD and unipolar depression self-poisoning subgroups...

The aim of this study was to adapt the Comet assay in spermatozoa of the marine prawn Palaemon serratus to use it as a marker of sperm quality. Indeed, due to the characteristics of their spermatozoa, the measurement of DNA integrity is one of the few markers which can be transferred to crustaceans to assess the quality of their semen. In the first step, the methods of collecting and maintaining spermatozoa were optimized. Cell survival was estimated during kinetics of preservation (i.e. 1, 2, 4 and 8 h) in various suspension media to define artificial seawater (ASW) as optimal...

Veno-venous collaterals are sometimes seen in patients after the Fontan procedure. A 28-year-old female with tricuspid atresia who underwent the Fontan procedure had oxygen desaturation due to a giant veno-venous collateral. Coil embolization was performed for the collateral. After the procedure, she complained of severe back pain. Anti-inflammatory analgesics and steroids were not effective, although carbamazepine promptly relieved the intractable pain. Treatment-related pain after coil embolization for veno-venous collaterals in patients with Fontan physiology is quite rare, although cardiologists must recognize a critical condition to be differentiated from vascular occlusion...

Adverse drug reactions (ADRs) are considered as an important cause of morbidity and mortality. The hypersensitivity reactions are immune-mediated ADRs, which are dose-independent, unpredictable and have been associated with several HLA alleles. The present review aimed to describe HLA alleles that have been associated with different ADRs in populations worldwide, the recommendations of regulatory agencies and pharmacoeconomic information and databases for the study of HLA alleles in pharmacogenetics. A systematic search was performed in June 2016 of articles relevant to this issue in indexed journals and in scientific databases (PubMed and PharmGKB)...

When using lipid nanoparticles as drug carrier system it is important to know how much drug can be loaded to the nanoparticles. The mainly used drug loading procedure is an empirical approach dissolving the drug in the liquid lipid during preparation of the nanoparticles. This approach does not necessarily lead to the truly loadable amount, as the lipid can, e.g. be overloaded, in particular when it is processed in the heat. In this work, a different procedure, passive drug loading, was evaluated to determine the drug loading capacity of various lipid nanoparticles (supercooled trimyristin emulsion droplets, solid trimyristin nanoparticles, tristearin nanoparticles in the α-modification and cholesteryl myristate nanoparticles in the supercooled smectic as well as in the crystalline state)...

Many drugs with unknown safety profiles are administered to pregnant women, placing their offspring at risk. I assessed whether behavioral outcomes for children exposed during gestation to antidepressants, anxiolytics, anti-seizure, anti-nausea and sedative medications can be predicted by more extensive animal studies than are part of the FDA approval process. Human plus rodent data were available for only 8 of 33 CNS-active drugs examined. Similar behavioral and cognitive deficits, including autism and ADHD emerged in human offspring and in animal models of these disorders after exposure to fluoxetine, valproic acid, carbamazepine, phenytoin, phenobarbital, acetaminophen and ibuprofen...

Although significant advances are occurring in epilepsy research, about 30% of epileptic patients are still inadequately controlled by standard drug therapy. For this reason, it continues to be important to develop new chemical entities through which epilepsy could be effectively controlled. In this study, the anticonvulsant activity of forty-two dihydropyrimidin(thi)ones was explored and their efficacy was evaluated in rodents against the maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole tests...

The growing consumption of pharmaceuticals together with their incomplete removal in wastewater treatment plants (WWTPs) implies the occurrence of these compounds in natural water resources. To investigate the natural attenuation of selected pharmaceuticals (caffeine, acetaminophen, sulfamethoxazole, naproxen and carbamazepine) during vadose zone infiltration, unsaturated column (L 26.67 cm, Ø 7.62 cm) experiments, filled with a sandy-loamy soil, were performed using two input concentrations (100 and 1000 μg L(-1))...

Drug-resistance epilepsy (DRE) is attributed to the brain P-glycoprotein (P-gp) overexpression. We previously reported that nuclear factor-kappa B (NF-κB) played a critical role in regulating P-gp expression at the brain of the acute seizure rats. This study was extended further to investigate the interaction effect of NF-κB and pregnane X receptor (PXR) on P-gp expression at the brain of chronic epileptic rats treated with carbamazepine (CBZ). The chronic epileptic models were induced by the micro-injection of kainic acid (KA) into rats' hippocampus...

A 42-year-old patient presented with acute allodynia and hyperalgesia in her distal limbs, most severe in the innervation area of the ulnar nerve. The patient developed critical illness myopathy/polyneuropathy after septic shock 5 months prior to her presentation. After exclusion of differential diagnosis, "late onset small fiber neuropathy" after critical illness was diagnosed. Recent studies showed small fiber lesions during critical illness and in follow-up exams, where additionally neuropathic pain were proved...

For the first time the occurrence of 26 nitrogen heterocyclic polyaromatic hydrocarbons (N-HETs) and the antiepileptic drug carbamazepine (CBZ) as a marker for anthropogenic influence was determined in an entire river system and its influents. Besides the investigation of diurnal and annual variations in concentrations, dilution and load calculations, the aims were to facilitate transferability to other rivers by identifying sources of the different substances. To create a sufficient database over 180 aqueous samples from the River Fuhse (Lower Saxony, Germany), its catchment area, effluents of municipal and industrial wastewater treatment plants (WWTPs) and rainwater were analyzed...

A quick, sensitive multiresidue method was developed for the analysis of 19 multiclass pharmaceuticals and personal care products (PPCPs) in surface water and sewage water. The proposed modified QuEChERS method involved the extraction of water samples (10 mL) with acetonitrile (10 mL) after the addition of 1% acetic acid, 4 g magnesium sulfate, and 0.2 g ammonium acetate, and was validated in distilled water, surface water, and sewage water with respect to linearity, LOD and LOQ, precision, and accuracy. The LOD and LOQ varied within the ranges of 0...

Oxidation and removal of organic micropollutants (OMPs) on ultrapure (UPW) and natural water (NW) by ozone (O3) and ozone/powdered activated carbon (O3/PAC) have been studied. The OMPs atrazine (ATZ, herbicide), carbamazepine (CBZ, anticonvulsant), diclofenac (DCL, anti-inflammatory) and triclosan (TCS, antimicrobial) are incorporated continuously and uncontrolled on water treatment systems (e.g., drinking water treatment plants, wastewater treatment plants). Batch experiments on ultrapure and natural water showed that ATZ treated with O3 and O3/PAC has the slowest transformation rate (>90% at 30min reaction) while CBZ, DCL and TCS were oxidized very fast (>90% at ~5min)...

Poor removal of many pharmaceuticals and personal care products (PPCPs) in sewage treatment leads to their discharge into the receiving waters, where they may cause negative effects. Their elimination from the water column depends of several processes, including photochemical and biological degradation. We have focused this research on comparing the degradation kinetics of a wide number (n=33) of frequently detected PPCPs considering different types of water, pH and solar irradiation. For those compounds that were susceptible of photodegradation, their rates (k) varied from 0...
