Ecotoxicity screening evaluation of selected pharmaceuticals and their transformation products towards various organisms

The intensive development of medical science has led to an increase in the availability and use of pharmaceutical products. However, nowadays, most of scientific attention has been paid to the native forms of pharmaceuticals, while the transformation products (TPs) of these substances, understood herein as metabolites, degradation products, and selected enantiomers, remain largely unexplored in terms of their characterization, presence, fate and effects within the natural environment. Therefore, the main aim of this study was to evaluate the toxicity of seven native compounds belonging to different therapeutic groups (non-steroidal anti-inflammatory drugs, opioid analgesics, beta-blockers, antibacterial and anti-epileptic drugs), along with the toxicity of their 13 most important TPs. For this purpose, an ecotoxicological test battery, consisting of five organisms of different biological organization was used. The obtained data shows that, in general, the toxicity of TPs to the tested organisms was similar or lower compared to their parent compounds. However, for example, significantly higher toxicity of the R form of ibuprofen to algae and duckweed, as well as a higher toxicity of the R form of naproxen to luminescent bacteria, was observed, proving that the risk associated with the presence of drug TPs in the environment should not be neglected.

Sub and supercritical water oxidation of pharmaceutical wastewater

Sub and supercritical water oxidation (Sub- CWO & SCWO) technology has gained attention over the past few years due to near complete conversions at shorter residences times. A pharmaceutical sample containing variety of analgesics, antibiotics, antipyretics, antifungal, beta-blockers and drug intermediates contributing to overall total organic carbon (TOC) of 2017 ¡À 49 mg/L was collected from a nearby pharmaceutical industry for this research. The sample was subjected to sub and supercritical water oxidation both in batch and continuous processes. A maximum removal efficiency of 80.1% was achieved with excess oxidant (oxidation coefficient (OC 3)) at 400 C for 60 min residence time in batch reactor. The pharmaceutical sample was also processed in continuous supercritical water reactor by varying both temperature (400-550 C) and oxidant coefficient (0-2) at 23 MPa for 60 s residence time. With the operating temperature of 550 C and OC 2 resulted in maximum removal of the pharmaceutics with efficiency of 97.8%.

Routine analytical method for monitoring the main metabolites for a recurrent group of parabens and pharmaceuticals in wastewater and tap water

The presence of parabens and pharmaceuticals on the aquatic environment has been widely evaluated in the last years. Nevertheless, there is scarce information about the occurrence of their metabolites and/or degradation products in spite of the fact that they can be more toxic or more concentrated than their parent compounds. One of the main drawbacks for their monitoring is the lack of simple and reliable analytical methods for their routine determination. In this work, an analytical method has been developed and validated for the simultaneous extraction and determination of the main metabolites of the pharmaceuticals diclofenac, ibuprofen, sulfamethoxazole, carbamazepine and caffeine and of the parabens methylparaben and propylparaben and their parent compounds in wastewater and tap water samples. Sample extraction was carried out by conventional solid-phase extraction with OASIS HLB cartridges. Analytical determination was carried out by liquid chromatography-tandem mass spectrometry with electrospray ionization. Average accuracy was in the range from 66 to 120% in wastewater and from 86 to 120% in tap water. Precision, expressed as relative standard deviation, was lower than 17% for all the compounds. Method quantification limits were in the range from 1.0 to 33?ng?L?1 in wastewater and from 0.5 to 28?ng?L?1 in tap water. The method was applied to wastewater and tap water samples. None of the target compounds was detected in tap water whereas all of them were detected in wastewater. Concentrations of the metabolites were similar or higher than those of the parent compounds.

Saliva and plasma monohydroxycarbamazepine concentrations in pediatric patients with epilepsy

Background: Monohydroxycarbamazepine (MHD, 10-hydroxycarbamazepine) is the main active metabolite of oxcarbazepine (OXC). The present study aims to investigate the relationship between plasma and saliva concentrations of MHD in Chinese children with epilepsy. Methods: Plasma and saliva samples were collected and MHD levels were measured by high-performance liquid chromatography system. Linear regression analysis was conducted between the dose of OXC and saliva concentrations, between the dose of OXC and plasma concentrations, and between the saliva concentrations and plasma concentrations. Student’s t-test was used for unpaired data. A one-way analysis of variance was used for analyzing co-medication in subgroups of patients. Results: A total of 58 blood samples and 58 saliva samples were obtained from 52 pediatric epileptic patients, with a median age of 5.67 years (0.58-15 years, 23 males and 29 females). There was an apparent positive correlation between the plasma and saliva MHD concentrations [Y = 0.77x 2 0.85 (n = 58), R = 0.908, P , 0.01]. MHD plasma and saliva concentrations were positively correlated to daily drug dose (r = 0.461 and 0.417; P , 0.01 respectively). The saliva/plasma MHD ratio was around 0.71 and had no significant difference with age, gender, and combined medications. When data were analyzed for subgroups (one group taking OXC as monotherapy, the second group taking OXC in add-on with non-enzyme-inducing antiepileptic drugs, and the third group taking OXC in add-on with hepatic-enzyme-inducing antiepileptic drugs or moderate inducers), no significant difference was found between plasma and saliva MHD concentrations in all the above 3 groups. Conclusions: High correlation between plasma and saliva MHD levels supported the use of saliva as an alternative to plasma for OXC monitoring in children with epilepsy.
