Abstract
The ability to determine antihistaminic drugs in biological matrices is critical for the medication adherence assessment. Among these antihistaminic medications, cyproheptadine (CPD); that is acting as a potent first-generation antihistaminic drug that has been extensively prescribed for allergic patients. Most of the established approaches for CPD detection are not appropriate for this purpose owing to their weak sensitivity, lack of rapidity, and complicated experimental procedures. Herein, we present a very fast, highly sensitive, and reproducible approach for the detection of CPD in its pure form, tablet formulation, and spiked human plasma. The photoluminescence approach depends on hindering the intramolecular photoinduced electron transfer (PET) effect of the lone pair of the N-atom present on the piperidine ring of CPD by making the surrounding medium acidic using 1.0 M acetic acid. Based on blocking PET, the target CPD drug has been sensitively detected from 5.0 to 500 ng mL-1 with a very low detection and quantitation limit of 7.01 and 21.25 ng mL-1, respectively. Moreover, the established approach was used for checking the tablet content uniformity testing for each tablet and spiked human plasma, and noteworthy, the matrices interference was insignificant.

Abstract
Cyproheptadine (CYP) is an antihistaminic and anti-serotonin drug used to improve the clinical course of hospitalized patients severely affected by COVID-19 and requiring supplemental oxygen. Thin layer chromatography (TLC)-densitometry method was developed and validated for the estimation of CYP and its impurity, dibenzosuberone and its degradation product: 10, 11-dihydroxy-dibenzosuberone. The toxicity profiles of CYP impurity and degradation product were studied and the in silico data, using pre-ADMET software, proved their toxicity. A developing system of hexane: methanol: ethyl acetate: formic acid: triethylamine (8:1:1:0.05:0.1, by volume) was used with densitometric scanning at 245 nm. International Conference of Harmonization guidelines were obeyed for method validation. The proposed method was applied on CYP pharmaceutical formulation whose results showed no significant difference from results of the reported chromatographic method regarding accuracy and precision. Method's greenness was evaluated by analytical Eco scale, Green Analytical Procedure Index, and Analytical greenness approach tools. The developed method can be applied for safety check analysis of CYP containing formulations and detection and even quantification of its related toxic components in quality control laboratories at high sensitivity up to 20-fold than the reported chromatographic method.

Abstract
Antibiotics are among the most common medicine groups since they are used to treat infectious diseases, as nutritional supplements in livestock breeding, and for preservation in the food industry. Turkey is among the highest antibiotic consumers in the world. In the present study, the most popular 14 antibiotics available in Turkey were monitored in one hospital sewage and two urban wastewater treatment plant influents and effluents seasonally in Istanbul province, the largest metropolitan center in Turkey. The present research aimed to develop a robust analytical method to determine 14 antibiotics, including six chemical groups, in environmental matrices which are considered significant antibiotic pollution sources, namely hospital sewage and urban wastewater. Solid-phase extraction (SPE) and UPLC-MS/MS analysis parameters included optimized column temperature, eluent, mobile phase, and flow rate. Three SPE cartridges were employed in recovery studies. The antibiotic recovery rates varied between 40 and 100%, and all analytes were identified within 3 min with UPLC-MS/MS under optimal conditions. It was determined that method detection limits (MDLs) varied between 0.07 and 2.72 µg/L for the antibiotics. In all seasons, the highest beta-lactam group antibiotic concentrations were identified in hospital sewage. The season with the greatest variety of antibiotics in urban wastewater was spring. Clarithromycin and ciprofloxacin were the antibiotics determined at the highest concentration in the influent and effluent of the wastewater treatment plant in all seasons. This study showed that the most widely used beta-lactam group antibiotics were found in high amounts in hospital sewage wastewater but in low concentrations in the treatment plants, and hence, it is seen that the degradability of beta-lactam group antibiotics was high. The presence of clarithromycin, ciprofloxacin, lincomycin, levofloxacin, and trimethoprim antibiotics in hospital sewage in higher amounts and also in inlet and outlet of wastewater treatment plants proves that those are resistant antibiotics.

Abstract
Abstract
This study establishes a method for rapid detection of clonidine and cyproheptadine in foods of animal origin. In order to obtain the best detection method, capillary zone electrophoresis (CZE), large volume sample stacking (LVSS), and sweeping-micellar electrokinetic capillary chromatography (sweeping-MEKC) were used respectively. The limits of detection (LODs) of clonidine and cyproheptadine by LVSS-CZE were 0.028 μg mL−1 and 0.034 μg mL−1, and those by sweeping-MEKC were 0.023 μg mL−1 and 0.031 μg mL−1, respectively. Compared with the CZE method, the two online pre-concentration technologies have greatly improved the detection sensitivity and achieved good enrichment results. However, compared with the sweeping-MEKC system, the LVSS system consumed a longer time and was greatly affected by the actual sample matrix. The sweeping-MEKC method was proved to be suitable for real sample analysis. Under the best sweeping-MEKC conditions, clonidine and cyproheptadine could be well separated within 8 min and good linear relationships in the range of 0.1–1.0 μg mL−1 (r
2 > 0.99) were obtained. This method was successfully applied to the determination of clonidine and cyproheptadine in animal-derived foods with the recoveries of 82.3%–90.1% and the relative standard deviations (RSDs) less than 3.11%. The sweeping-MEKC method is simple to operate and has great potential in the rapid detection of clonidine and cyproheptadine in animal-derived foods.

Abstract
This work presents a sensitive, accurate and selective RP-HPLC method for simultaneous determination of cyproheptadine HCl (CPH), its impurity B (dibenzosuberone) and CPH oxidative degradation product (10,11-dihydroxy-dibenzosuberone) in bulk powder and in pharmaceutical formulation. The RP-HPLC method depends on isocratic elution using C8 column and mobile phase consisting of 0.05 M KH2PO4 buffer:methanol (35:65, v/v, pH = 4.5) at a flow rate of 2 mL/min, and the eluant was monitored at 245 nm. Good resolution was obtained with tR values of 3.05, 7.54 and 6.17 min for CPH, impurity and oxidative degradate, respectively. The proposed method has been validated as per ICH guidelines using pure forms of CPH, its impurity and degradation product in pharmaceutical formulation with an accuracy of 100.48, 100.16 and 100.11, respectively. Additional spiking experiments yielded an accuracy of 100 ± 1.6%. Repeatability and intermediate precision results indicated acceptable low <2% RSD values. Moreover, the developed method's statistical results were favorably compared to the previously reported method results regarding both accuracy and precision. The developed method can be applied for analysis of the three components in quality control laboratories.

Abstract
Cyproheptadine hydrochloride (CYP), used as human and veterinary drug, has been used illegally as feed additive for food-producing animals, which could remain in food and jeopardize human health. There is a need for on-site detection of CYP residue in animal-derived food. In this study, a hapten was designed, and a specific monoclonal antibody (mAb) was developed to detect CYP with an IC50 of 1.38 ng/mL and negligible cross-reactivity (CR) for other analogs. Forthermore, a high sensitive immunochromatographic assay (QBs-ICA) was developed using quantum dot nanobeads as reporters. The assay showed the linear detection range (IC20-IC80) of 0.03-0.52 ng/mL, the limit of detection (LOD) and visual detection limit (VDL) reached to 0.01 and 0.625 ng/mL, respectively. Spiked recovery study in pig urine and pork confirmed that the QBs-ICA was applicable for on-site testing. This assay showed better sensitivity and speedy than the reported instrumental analysis and immunoassays.

Abstract
Nitrogen, phosphorus co-doped porous carbon nanofiber (N, P-PCNF) is prepared by electrospinning the mixed solution of polyacrylonitrile (PAN), polyvinylpyrrolidone (PVP) and phosphoric acid followed by carbonization. The N, P-PCNF as a modified electrode material is directly used to fabricate an electro-chemiluminescent sensor for determination of cyproheptadine, and owing to the large specific area, more active sites and promotion of electron transfer, the sensor exhibits high electro-catalytic activity, high sensitivity, a good linear relationship ranging from 1.0 × 10−7 to 1.0 × 10−5 mol L−1 and a low detection limit (2.89 × 10−8 mol L−1). In addition, the good recoveries indicate that the sensor is a promising device for the detection of cyproheptadine in real samples. Nitrogen, phosphorus co-doped porous carbon nanofiber is as electrode modified material to fabricate an electro-chemiluminescent sensor for detecting cyproheptadine.![]()

Abstract
Cyproheptadine hydrochloride (CYP HCl) {4-(5H-dibenzo[a,d]-cyclohepten-5-ylidene)-1-methylpiperidine hydrochloride} is a first-generation antihistamine with additional anticholinergic, antiserotonergic, and local-anesthetic properties. The geometry optimization, Mulliken atomic charges and wavenumber and intensity of the vibrational bands of all of the possible modes of CYP HCl have been calculated using ab initio Hartree-Fock (HF) and density functional theory (DFT) employing the B3LYP functional with the 6-311G(d,p) basis set. We have compared the calculated IR and Raman wavenumbers with experimental data. Quantum-chemical calculations of the geometrical structure, energies, and molecular electrostatic potential and NBO analysis of CYP HCl have been performed using the B3LYP/6-311G(d,p) method. The electric dipole moment (μ), static polarizability (α) and the first hyperpolarizability (β) values of the title compound have been computed using HF and DFT methods. The study reveals that the antihistaminic pharmacological property of CYP HCl has a large β value and, hence, may in general have potential applications in the development of non-linear optical materials. The experimental and calculated results for CYP HCl have also been compared with those for mianserin HCl.

Abstract
A simple, specific, rapid and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the analysis of fluticasone propionate (FP) in pharmaceutical formulations was developed and validated using deflazacort as internal standard (IS). The LC-MS/MS method was carried out on a C8 column (50 mm) with a mobile phase consisted of methanol : water (95 : 5, v/v) 100 mM formic acid-50 mM ammonium acetate (90 : 5 : 5, v/v/v). The mass spectrometry method was performed employing positive atmospheric pressure chemical ionization technique, operating in multiple reaction monitoring mode. The chromatographic separation was obtained within 1.5 min and it was linear in the concentration range of 10-1000 ng mL(-1). Moreover, method validation demonstrates acceptable results for the specificity, accuracy, precision and robustness. The proposed method was successfully applied for the quantitative analysis of FP nasal sprays and the results were compared to validated liquid chromatography and capillary electrophoresis methods with photodiode array detectors showing non-significant difference (P > 0.05).
