Abstract
Hydrophilic interaction liquid chromatography (HILIC) has inherent merits over RP-HPLC in the analyzing of hydrophilic substances. Accordingly, an innovative HILIC-UV methodology is proposed for the simultaneous estimation of ethyl paraben (PRN), fluconazole (FLZ) and moxifloxacin hydrochloride (MOX) in raw materials and pharmaceutical eye gel. The separation process was conducted using Waters XBridge™ HILIC column (100 mm × 4.6 mm, 3.5 μm particle size) at room temperature. Isocratic mobile phase containing acetonitrile: 0.1% triethylamine buffer (90:10, v/v, pH 5.0), was pumped at flow rate 1.0 mL/min and detected at 260 nm. Under these optimized conditions, PRN, FLZ and MOX showed rectilinear relationships with the concentration ranges (0.5–6.0), (5.0–50.0) and (5.0–60.0) μg/mL, respectively. The developed method offered at least fivefold increase in sensitivity within shorter time than the reported methods. Three greenness assessment tools namely: Analytical eco-scale, GAPI and AGREE were exploited to investigate the method's impact on the environment and conduct a comparative study with the reported methods. International council of Harmonization (ICH) guidelines have been followed to calculate validation parameters. The statistical comparison between results of the suggested method and the comparison method showed no discrepancy confirming accuracy of the method.

Abstract
An efficient and reliable method using LC-MS/MS was established and validated for the simultaneous quantification of meropenem and imipenem in rat plasma. An electronic spray ion source in the positive multiple reaction monitoring mode was used for the detection and the transitions were m/z 384.6 → m/z 141.2 for meropenem, m/z 300.1 → m/z 141.8 for imipenem and m/z 423.4 → m/z 207.1 for matrine (IS). The calibration curves of meropenem and imipenem were linear in the range of 0.50-200 μg/mL. Satisfactory separation was achieved with a total run time of 3.0 min, the injection volume was 3 μl. The retention times of meropenem, imipenem and IS were 1.19, 1.14 and 1.13 min, respectively. Meropenem and imipenem are easily hydrolyzed in plasma. HEPES was used as a stabilizer and added to the plasma samples immediately after centrifugation. Extractions of meropenem, imipenem and IS were carried out by protein precipitation with acetonitrile. The specificity, precision and accuracy, stability, recovery and matrix effects were within acceptance limits. This method was successfully applied to investigate the pharmacokinetics of intravenous injection of meropenem and imipenem single administration or combined with sulbactam in rats. We found that sulbactam has no influence on the pharmacokinetics behavior of meropenem or imipenem.

Abstract
Aim: A simple, rapid, economical and sensitive HPLC-UV method was developed for the simultaneous quantification of ceftolozane and tazobactam in plasma samples. Methodology: After deproteinization followed by a liquid–liquid back-extraction, the compounds were separated on a C18 column (150 mm × 4.6 mm, 5 μm) with UV-visible detection at 220 nm. The mobile phase consisted of acetonitrile and potassium dihydrogenphosphate buffer at pH 3.0 (8:92, v/v), delivered isocratically at a flow rate of 1.0 ml/min and at a column oven temperature of 30°C. Cefepime was used as an internal standard. Results: Linearity was achieved in the concentration range of 0.50–100.00 μg/ml for ceftolozane and 0.25–50.00 μg/ml for tazobactam. The intra- and interday precision showed good reproducibility with coefficients of variation of less than 9.26% for ceftolozane and 9.62% for tazobactam. Conclusion: The sample preparation procedure avoids expensive or time-consuming steps used by other previously published methods. The methodology was validated according to standard guidelines and was used for quantification of ceftolozane and tazobactam in plasma samples from critically ill patients.

Abstract
New accurate, sensitive and selective spectrophotometric and chemometric methods were developed and subsequently validated for determination of Imipenem (IMP), ciprofloxacin hydrochloride (CIPRO), dexamethasone sodium phosphate (DEX), paracetamol (PAR) and cilastatin sodium (CIL) in human urine. These methods include a new derivative ratio method, namely extended derivative ratio (EDR), principal component regression (PCR) and partial least-squares (PLS) methods. A novel EDR method was developed for the determination of these drugs, where each component in the mixture was determined by using a mixture of the other four components as divisor. Peak amplitudes were recorded at 293.0 nm, 284.0 nm, 276.0 nm, 257.0 nm and 221.0 nm within linear concentration ranges 3.00-45.00, 1.00-15.00, 4.00-40.00, 1.50-25.00 and 4.00-50.00 μg mL(-1) for IMP, CIPRO, DEX, PAR and CIL, respectively. PCR and PLS-2 models were established for simultaneous determination of the studied drugs in the range of 3.00-15.00, 1.00-13.00, 4.00-12.00, 1.50-9.50, and 4.00-12.00 μg mL(-1) for IMP, CIPRO, DEX, PAR and CIL, respectively, by using eighteen mixtures as calibration set and seven mixtures as validation set. The suggested methods were validated according to the International Conference of Harmonization (ICH) guidelines and the results revealed that they were accurate, precise and reproducible. The obtained results were statistically compared with those of the published methods and there was no significant difference.

Abstract
<p>A bioanalytical method was developed and applied to quantify the free imipenem concentrations for pharmacokinetics and PK/PD correlation studies of the dose adjustments required to maintain antimicrobial effectiveness in pediatric burn patients. A reverse-phase Supelcosil LC18 column (250 x 4.6 mm 5 micra), binary mobile phase consisting of 0.01 M, pH 7.0 phosphate buffer and acetonitrile (99:1, v/v), flow rate of 0.8 mL/min, was applied. The method showed good absolute recovery (above 90%), good linearity (0.25-100.0 µg/mL, r<sup>2</sup>=0.999), good sensitivity (LLOQ: 0.25 µg/mL; LLOD: 0.12 µg/mL) and acceptable stability. Inter/intraday precision values were 7.3/5.9%, and mean accuracy was 92.9%. A bioanalytical method was applied to quantify free drug concentrations in children with burns. Six pediatric burn patients (median 7.0 years old, 27.5 kg), normal renal function, and 33% total burn surface area were prospectively investigated; inhalation injuries were present in 4/6 (67%) of the patients. Plasma monitoring and PK assessments were performed using a serial blood sample collection for each set, totaling 10 sets. The PK/PD target attained (40%T>MIC) for each minimum inhibitory concentration (MIC: 0.5, 1.0, 2.0, 4.0 mg/L) occurred at a percentage higher than 80% of the sets investigated and 100% after dose adjustment. In conclusion, the purification of plasma samples using an ultrafiltration technique followed by quantification of imipenem plasma measurements using the LC method is quite simple, useful, and requires small volumes for blood sampling. In addition, a small amount of plasma (0.25 mL) is needed to guarantee drug effectiveness in pediatric burn patients. There is also a low risk of neurotoxicity, which is important because pharmacokinetics are unpredictable in these critical patients with severe hospital infection. Finally, the PK/PD target was attained for imipenem in the control of sepsis in pediatric patients with burns.</p>

Abstract
A hydrophilic interaction chromatography/mass spectrometry (HILIC-MS)-based assay for imipenem (IMP) and cilastatin (CIL) was recently reported. This orthogonal electrospray ion source-based (ORS) assay utilized nonvolatile salt (unremovable) to stabilize IMI in plasma. Unfortunately, this method was not applicable to conventional MS with off-axis spray (OAS-MS) because MS sensitivity was rapidly deteriorated by the nonvolatile salt. Therefore, we aimed to find a nonvolatile salt- and ion suppression-free approach to stabilize and measure the analytes in plasma using OAS-MS. Acetonitrile and methanol were tested to stabilize the analytes in the plasma samples. The recoveries, matrix effects and stabilities of the analytes in the stabilizer-treated samples were studied. The variations in MS signal intensities were used as the indicator of the assay ruggedness. The results show that a mixture of methanol and acetonitrile (1:1) is best for the storage and measurement of IMP and CIL in human plasma. Utilization of this precipitant not only blocked the hydrolysis of the analytes in plasma but also resulted in an ion suppression-free, fast (120 s per sample) and sensitive detection. The sensitivity obtained using the less sensitive OAS-MS (API3000, 4 pg on column) is much greater than that of the published ORS-MS-based assay (API4000, 77 pg on column). The ruggedness of the assay was demonstrated by its constant MS signal intensity. In conclusion, an improved HILIC/MS-based assay for IMP and CIL was established. The approach presented here provides a simple solution to the challenge of analyzing hydrolytically unstable β-lactam antibiotics in biological samples.

Abstract
A simple offline LC-MS/MS method for the quantification of sitagliptin in human plasma is described. Samples are prepared using protein precipitation. Filtration of the supernatants through a Hybrid-SPE-PPT plate was found to be necessary to reduce ionization suppression caused by co-elution of phospholipids with sitagliptin. The sitagliptin and its stable isotope labeled internal standard (IS) were chromatographed under hydrophilic interaction chromatography conditions on a Waters Atlantis HILIC Silica column (2.1 mm x 50 mm, 3 microm) using a mobile phase of ACN/H(2)O (80/20, v/v) containing 10 mM NH(4)Ac (pH 4.7). The sample drying after protein precipitation due to high organic content in the sample is not necessary, because HILIC column was used. The analytes were detected with a tandem mass spectrometer employing a turbo ion spray (TIS) interface in positive ionization mode. The multiple reaction monitoring (MRM) transitions were m/z 408-->235 for sitagliptin and m/z 412-->239 for IS. The lower limit of quantitation (LLOQ) for this method is 1 ng/mL when 100 microL of plasma is processed. The linear calibration range is 1-1000 ng/mL for sitagliptin. Intra-day precision and accuracy were assessed based on the analysis of six sets of calibration standards prepared in six lots of human control plasma. Intra-day precision (RSD%, n=6) ranged from 1.2% to 6.1% and the intra-day accuracy ranged from 97.6% to 103% of nominal values.
