Alpa C. Sheth, Paresh U. Patel
Elemental impurities in drug products may arise from several sources; they may be residual catalysts that were added intentionally in the synthesis or may be present as impurities (e.g., through interactions with processing equipment or container/closure systems or by being present in components of the drug product). Because elemental impurities do not provide any therapeutic benefit to the patient, their levels in the drug product should be controlled within acceptable limits. The main objective of the ICH (Q3D) guideline applies to new finished drug products and new drug products containing existing drug substances. The drug products containing purified proteins and polypeptides. This guideline does not apply to herbal products, radiopharmaceuticals, vaccines, cell metabolites, DNA products, allergenic extracts, cells, whole blood, cellular blood components, or blood derivatives, including plasma and plasma derivatives. The evaluation of the toxicity data for potential elemental impurities; the establishment of a permitted daily exposure (PDE) for each element of toxicological concern; application of a risk-based approach to control elemental impurities in drug products. Different analytical techniques for elemental impurities detection: flame atomic absorption spectrometry (FAAS), graphite furnace atomic absorption spectrometry (GFAAS), atomic fluorescence spectrometry, X-ray fluorescence spectrometry (XRF), instrumental neutron activation analysis (INAA), inductively coupled plasma-atomic emission spectroscopy (optical emission spectroscopy, ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), and microwave plasma atomic emission spectrometry (MP-AES).

Muthanna J. Mohammed, Hiyam A. Ebraheem
Essential and fixed oils of anise plant (Pimpinella anisum (P. anisum)) growing in Iraq have been investigated regarding their chemical components, antioxidant and antimicrobial properties. Essential oils were extracted using the Clevenger-apparatus, while fixed oil was extracted using a Soxhlet apparatus. Gas chromatography-mass spectrometry (GC-MS) was used for the analysis of the oil components. Six strains of bacteria, namely S. epidermidis, S. aureus, E. coli, B. cereus, P. vulgaris and S. typhimurium were tested against the antimicrobial activity of each oil. Anise oil demonstrated a broad antibacterial property range, against Gram-positive and Gram-negative bacteria, through the inhibition zone. The antibiotic sensitivity test was performed by disk diffusion process against the test organisms. The agar dilution method was used at five different concentrations (12.5, 25, 50, 100, and 200 mg/mL) throughout the test. The Minimum Inhibitory Concentration (MIC) was determined for each volatile and fixed oil. The DPPH radical scavenging assay was used to test the antioxidant activities of essential and fixed oils. Anise oil showed excellent antioxidant activity, in comparison with the reference compounds. Anise oil has the potential to be used as a therapeutic, antimicrobial, and antioxidant agent.

The stability-indicating reverse-phase high-performance liquid chromatography (RP-HPLC) method is precise; it has been developed for the simultaneous estimation of assay of guaifenesin (GN) and dextromethorphan HBr (DN) in drug substance and drug product. The chromatographic separation was done in an isocratic mode using the Syncronus C8 (250 × 4.6 mm, 5 μ particle size) column with mobile phase containing a 10 mM ammonium acetate in water (modulated pH 4.30 with orthophosphoric acid) and acetonitrile in the ratio of 60:40 (% v/v) used for efficient chromatographic separation. The flow rate of the mobile phase was 1.0 mL/min with ambient column temperature and detection of wavelength at 279 nm; injection volume 10 μL was fixed for achieving good elution of eluents. The retention time for GN was found to 3.46 minutes and DN was found to 7.58 minutes. GN and DN were linear in the concentration range from 357 to 1428 and 19 to 75 μg/mL, respectively. Regression analysis showed that the r-value (correlation coefficient) greater than 0.999 for GN rvalue was found to be 0.999, DN r-value was found to be 0.999. Limit of detection (LoD) and limit of quantification (LoQ) of GN was found to be 0.151 and 0.904 μg/mL, DN was found to be 0.241 and 0.726 μg/mL. The developed method was validated and found to be accurate, specific, and robust. Both the drugs were subjected to the stress conditions like acidic, basic, oxidative, photolytic, and thermal conditions. The degradation results were found to be satisfactory. In peroxide stress condition, GN was found stable over DN, and DN was found to degrade significantly. The degradation products were well resolved from GN, DN, and their impurities. The peak purity test results confirmed that the GN and DN peak were homogenous and pure in all stress conditions, thus proving the stability-indicating nature of the method. This method could be applied for the simultaneous estimation of GN and DN in drug substance and drug product.

Suhayla H. Shareef, Kawa Amin
Background and objective: Asthma is not a single disease but, rather, a heterogeneous inflammatory disorder with various pathogenic mechanisms. A key element of severe asthma (SA) has been stated to be eosinophilic inflammation (EI). However, there is no serum biomarker that can reliably predict EI in SA. In this regard, the present study was carried out to evaluate the biomarkers of allergic asthma (AA) and their association with serum parameters. Methods: The present cohort study consisted of 66 AA and 61 healthy controls (HC) from Jan. 2017 to Nov. 2018. Data on variables like all types of leukocyte cells, total and specific serum IgE, ECP, Tryptase, IL-18, CD-20, and FEV1 were obtained. For comparison between the unpaired variables, the Mann-Whitney U test, χ2 test, and Kruskal Wallis H test was used. Results: Symptoms (cough, wheezes, dyspnea) and family history were found as significant indicators for AA (p <0.05). The AA and HC were significantly different in terms of blood and serum parameters [i.e., WBC, lymphocyte, monocyte, neutrophil, eosinophil, basophil, total IgE, ECP, Tryptase, IL-18, and CD-20] (p <0.05); therefore, these factors might be reliable indicators of AA. Also, most of the biomarkers were significantly correlated with the serum parameters, which reveal the reliability of these variables as indicators of AA. Conclusion: All types of leukocyte cells were found as reliable biomarkers to diagnose AA patients from HC. Also, FEV1%, Total WBC, and serum total IgE, ECP, Tryptase, IL-18, and CD-20 were found as reliable biomarkers for the severity of AA.

Aseem Kumar, Anil Kumar Sharma, Rohit Dutt
The present work demonstrates a simple, rapid, precise, specific, and sensitive reverse-phase high-performance liquid chromatography (RP-HPLC) method for analyzing glimepiride in pure and tablet forms. The present method was developed using a C18 column 150 ×
4.6 mm, with 5 μm, and packing L1 maintained at a temperature of 30°C. The mobile phase was prepared by dissolving 0.5 gram of monobasic sodium phosphate in 500 mL of distilled water, pH of the solution adjusted to 2.1 to 2.7 with 10% phosphoric acid, and added 500 mL of acetonitrile. The mobile phase was pumped in the high-performance liquid chromatography (HPLC) system at a flow rate of 1 mL/min, and separation was carried out at 228 nm, using an ultraviolet (UV) detector. The chromatographic separation was achieved with peak retention time (RT) at about 9.30 minutes, and the method was found to be linear over a concentration range of 40 to 140 μg/mL. The specificity of the method represented no interference of the excipients during the analysis, and stability testing after 24 hours also showed that the method is suitable and specific. The accuracy was between 99.93 to 99.96%, with limit of detection (LOD) and limit of quantitation (LOQ) being 0.354 μg/mL, 1.18 μg/mL, respectively. Satisfactory results were found for precision and robustness parameters during the development and validation stage for the analytical method. The proposed method was also adopted for the analysis of glimepiride tablets to improve the overall quality control. Using this method, symmetric peak shape was obtained with reasonable retention time. The retention time of glimepiride for six repetitions is 9.3 ± 0.1 minutes; the run time is 21 minutes. The proposed RP-HPLC method is a modification of the United States Pharmacopeia (USP) method, and it was found to be valid for glimepiride within concentration ranges 40 to 140 μg/mL, using C18 analytical columns, and isocratic elution with UV detection, and at 1 mL/min of flow rate.
