Abstract
The novelty of this work is the simultaneous analysis of sulbactam (SUL), ampicillin (AMP), and paracetamol (PARA) in human urine samples, using the environmentally benign RP-HPLC method. A C18 column was used in chromatographic separation using potassium dihydrogen phosphate (10 mmol L-1, pH 5)/ethanol (90 %, V/V) as the mobile phase; flow rate was 1.00 mL min-1. UV detection at 220 nm was used for quantification. The proposed method showed good linearity in the concentration ranges of 2.20-250.00 μg mL-1 for SUL, 2.50-250.00 μg mL-1 for PARA, and 14.50-250.00 μg mL-1 for AMP. Direct injection of urine samples with no prior extraction was performed. This method was found successful in moving towards greener studies of drugs' urinary excretion, by decreasing hazardous solvent consumption and waste. Moreover, the method was applied to investigate the urinary excretion of the drugs and possible interaction between ampicillin and paracetamol.

Abstract
Background:
The efficient analytical method for the analysis of nonsteroidal antiinflammatory
drugs (NSAIDs) in a biological fluid is important for determining the toxicological aspects
of such long-term used therapies.
Methods:
In the present work, multi-walled carbon nanotubes reinforced into a hollow fiber by chitosan
sol-gel assisted-solid/ liquid phase microextraction (MWCNTs-HF-CA-SPME) method followed
by the high-performance liquid chromatography-diode array detection (HPLC–DAD) was developed
for the determination of three NSAIDs, ketoprofen, diclofenac, and ibuprofen in human urine samples.
MWCNTs with various dimensions were characterized by various analytical techniques. The extraction
device was prepared by immobilizing the MWCNTs in the pores of 2.5 cm microtube via chitosan
sol-gel assisted technology while the lumen of the microtube was filled with few microliters of
1-octanol with two ends sealed. The extraction device was operated by direct immersion in the sample
solution.
Results:
The main factors influencing the extraction efficiency of the selected NSAIDs have been examined.
The method showed good linearity R2 ≥ 0.997 with RSDs from 1.1 to 12.3%. The limits of detection
(LODs) were 2.633, 2.035 and 2.386 µg L-1, for ketoprofen, diclofenac, and ibuprofen, respectively.
The developed method demonstrated a satisfactory result for the determination of selected drugs
in patient urine samples and comparable results against reference methods.
Conclusion:
The method is simple, sensitive and can be considered as an alternative for clinical laboratory
analysis of selected drugs.

Abstract
In 2006, India, Pakistan, and Nepal banned the manufacture of veterinary formulations of the nonsteroidal anti-inflammatory drug (NSAID) diclofenac. This action was taken to halt the unprecedented decline of three Gyps vulture species that were being poisoned by diclofenac residues commonly present in carcasses of domestic livestock upon which they scavenged. To assess the affect of this ban and evaluate residue prevelances of other NSAIDs, we present a method to detect diclofenac and eight more NSAIDs by liquid chromatography-mass spectrometry and apply this to 1488 liver samples from carcasses of livestock taken across seven Indian states. Diclofenac was present in 11.1% of samples taken between April and December 2006, and meloxicam (4%), ibuprofen (0.6%), and ketoprofen (0.5%) were also detected. Although meloxicam is safe for a range of avian scavengers, including Gypsvultures, data regarding the safety of other NSAIDs is currently limited. If wild Gyps on the Indian subcontinent are to survive, diclofenac bans must be completely effective, and NSAIDs that replace it within the veterinary drug market must be of low toxicity toward Gyps and other scavenging birds.

Abstract
An HPLC-MS/MS method has been developed for the selective quantitative analysis of paracetamol and its two major metabolites. The use of tandem MS enabled the detection and quantitation of metabolites in small sample sizes with high sensitivity and selectivity. Isocratic elution using acetonitrile and water containing formic acid combined with electrospray-tandem MS enabled the separation and accurate quantitation of each analyte and the internal standard 3-acetamidophenol. The on-column limits of detection for paracetamol, paracetamol sulfate, and paracetamol glucuronide were 2.4, 1.2, and 1.2 pmol, respectively. The method was applied to quantitate paracetamol and its metabolites in mouse urine. It is highly specific, sensitive, and easily adaptable to measure these analytes in biological fluids of other animals.

Abstract
Pharmacokinetic studies of topical ketoprofen formulations using continuous sampling techniques such as microdialysis (MD) or open-flow microperfusion (OFM) require sensitive assays due to small sample volumes. A simple and easy online-SPE-MS/MS method for ketoprofen analysis was developed for both MD and OFM samples obtained from rat dermal tissue. The quantification range is 25-5000 ng/ml with a limit of detection of 3 ng/ml using only 10 microl sample volume. The method is characterized by a simple setup using a short polymeric SPE column (OASIS HLB) for desalting with 1.5 min run times in combination with a sensitive MS detection in negative ESI MRM mode. An easy sample workup procedure was used which enables high throughput analysis of a large number of samples for pharmacokinetic studies. In addition, a commercial available (fenoprofen) as well as an isotopically labelled (deuterated ketoprofen) standard were investigated as potential internal standards. The method was validated according to FDA guidelines for bioanalytical validation in terms of accuracy, intra-batch and inter-batch precision, linearity, matrix effect, recovery and stability for both internal standards. Accuracies were 98-113% (fenoprofen) and 95-108% (deuterated ketoprofen), intra-batch precision was 2-3% R.S.D. (fenoprofen) and 2-6% R.S.D. (deuterated ketoprofen), and inter-batch precision was 2-6% R.S.D. (fenoprofen) and 3-6% R.S.D. (deuterated ketoprofen) over the entire quantification range. The presented method was applied to dermal interstitial fluid samples obtained in a topical administration study of ketoprofen in rats.

Abstract
A rapid and new liquid chromatography-mass spectrometry with ion-trap detection method for the determination of meloxicam (MLX), flunixin meglumine (FLU), carprofen (CPF), and tolfenamic acid (TOLF) in animal tissue is described. MRLs between 10 and 500 microg kg(-1) in muscle and between 65 and 1000 microg kg(-1) in liver, from different animal species have been established in the EU for these compounds. After chemical hydrolysis, an organic extraction from homogenised tissue was performed. Final extract was injected in a liquid chromatograph with an ion-trap mass spectrometer with electrospray interface. Four identification points (one precursor and two product ions) and a minimum of one ion ratio was monitored for each compound. For quantitative purposes flunixin-D3 (FLU-D3) was used as internal standard. The method was validated using fortified blank muscle and liver from different animal species according to the 2002/657/EC European decision criteria. The decision limits (CCalpha) and detection capabilities (CCbeta) were determined and their values were at concentrations near the MRL for each substance.

Abstract
We investigated a method for the simultaneous screening, identification, and quantitative determination of salicylic acid, acetaminophen, theophylline, barbiturates, and bromvalerylurea, drugs that frequently cause acute poisoning in Japan and therefore require rapid analysis for effective treatment in the clinical setting. The method employs liquid chromatography/electrospray mass spectrometry (LC/MS) of solid-phase extracted serum samples. For LC/MS ionization, the electrospray-ionization method was used, with acetaminophen in the positive-ion mode, and salicylic acid, theophylline, phenobarbital, bromvalerylurea, pentobarbital, amobarbital, and o-acetamidophenol (internal standard) in the negative-ion mode, the base ions were used in each case for quantitative analysis. Quantitation was possible for the following sample concentration ranges: salicylic acid and acetaminophen, 100 to 5 microg/ml; theophylline, 100 to 0.5 microg/ml; and phenobarbital, bromvalerylurea, pentobarbital, and amobarbital, 100 to 1 microg/ml. Using full-scan mass spectrometry, the lower detection limits of 1 microg/ml for salicylic acid and acetaminophen, 0.1 microg/ml for theophylline, and 0.5 microg/ml for phenobarbital, bromvalerylurea, pentobarbital, and amobarbital were adequate for identifying acute poisoning. When each compound was added to serum to a final concentration of 5 microg/ml and solid-phase extraction was performed using Oasis HLB 1-cc (30-mg), the mean recovery rate of each compound was 89.2 to 96.1% (n=5), and the coefficients of variation of the intraday and interday assays were 3.55 to 6.05% (n=5) and 3.68 to 6.38% (n=5), respectively, which are acceptable. When this method of analysis was applied in testing the sera of a female patient who had consumed a large amount of an unknown commercial drug, salicylic acid and bromvalerylurea were identified, and the treatment strategy could be determined in accordance with the serum concentration of those drugs.
