Abstract
Ambroxol (AMB) is a member of the expectorant class, widely used as a secreolytic agent in patients to break up secretions. AMB is rapidly and effectively distributed from blood to tissue. The lungs have the highest concentration of AMB; accumulation of AMB in human lung tissue was detected at concentrations 15- to 20-fold greater than those reported in the circulation. Because of its wide range of actions and therapeutic applications may be worth looking into, particularly for respiratory symptoms, antioxidant, anti-inflammatory, influenza, and rhinovirus infections. Though several analytical methodologies have been established and confirmed for the AMB analysis in matrices of pharmaceutical and biological origins, novel sustainable, and economical methods are still to be choice of protocol to increase its sensitivity, reliability, and repeatability. Therefore, the present review offers an overview of critical analytical aspects regarding the HPLC, LC-MS/MS, HPTLC, capillary electrophoresis, spectrophotometry, and electrochemical methods for quantifying AMB in pharmaceutical and biological samples. Furthermore, this review will thoroughly discuss the physicochemical properties, stability, extraction conditions, instrumentation, and operational parameters of the targeted analyte. As a result, for the first time, this review complies with vital background information and an up-to-date interpretation of research undertaken by anticipated methodologies examined and implemented for the pharmaceutical analysis AMB.

Abstract
A stability-indicating HPLC method was developed for the simultaneous determination of paraben mixture and its degradation products in effervescent potassium chloride tablets. The chromatographic separation was achieved on a Waters Cortecs C18 column (2.7 μm, 4.6 × 150 mm) using gradient elution. The optimized mobile phase consisted of 0.1% orthophosphoric acid in purified water as solvent A and purified water, acetonitrile, and orthophosphoric acid (100:900:1, v/v) as solvent B. The flow rate was 0.8 mL/min, and column temperature was maintained at 35°C. The injection volume was 10 μL, and UV detection was carried out at 254 nm. The selectively developed method has optimal separation among p-hydroxybenzoic acid, methylparaben, ethylparaben, propylparaben, and butylparaben peaks in the presence of specified and unspecified degradation products in the determination of drug product. The mass balance obtained from forced degradation studies was ≥95% and thus proves the stability-indicating property of the developed method. The developed reversed-phase HPLC method has been validated according to the International Conference on Harmonization guidelines. The correlation coefficients for all the peaks were >0.9999. The results of the other validation parameters were found within the limits. Finally, the optimized method was used in the quality control lab for stability analysis.

Abstract
A rapid, simple, sensitive, and selective liquid chromatography-tandem mass spectrometry (LC-MS) test method was developed and validated for the trace level determination of 4-chlorobutyl-(S)-[4-chloro-2-(4-cyclopropyl-1,1,1-trifluoro-2-hydroxy-but-3yn-2-yl)phenyl] carbamate (4-CTHC). 4-CTHC is a potential genotoxic impurity in efavirenz drug substance and the acceptable level is 2.5 μg ml-1 with respect to analyte concentration according to ICH M7(R1) Multidisciplinary Guidelines M7(R1). The LC-MS/MS analysis of 4-CTHC impurity was carried out on a Kinetex C18 (150 × 4.6 mm, 5.0 μm) column. In this test procedure, the mobile phase was prepared with buffer (0.1% formic acid in water) and acetonitrile in the ratio of 1:3 (v/v). The method set flow rate was 0.4 ml min-1 . The method was developed with a short run time of <10 min. Selective ion monitoring acquisition mode and negative polarity electrospray ionization mode were used as an MS method to quantify genotoxic impurities at 422.25 Da. The method showed linearity in a range of 0.64-3.71 μg ml-1 with a correlation coefficient of 0.9992. The RSD for intra-day and inter-day precision was found to be <5%. The method's accuracy was in the range of 106.5-112.4% for the genotoxic impurity of 4-CTHC. The procedure was validated as per the current ICH Q2 (R1) guidelines and proved suitable for stability testing in the quality control laboratory for pharmaceutical preparations.

Abstract
A novel ultra-performance liquid chromatographic (UPLC) method has been developed and approved for the quantitative determination of enzalutamide (ENZ) and its impurities in drug product dosage form by applying the quality by design with design of experiments approach. An efficient chromatographic separation was achieved on a Waters ACQUITY CSH C18 (100 × 2.1 mm × 1.7 μm) column in gradient elution mode. A mixture of potassium phosphate monobasic buffer and acetonitrile (10 mm, adjusted to pH 4.0 with 1% orthophosphoric acid) at a flow rate of 0.2 mL min-1 (column temperature at 40°C) under ultraviolet detection at 270 nm was used for quantitation. The peak resolution among ENZ and its impurities (Impurity-1, Impurity-2, Impurity-3, Impurity-4, Impurity-5, Impurity-6 and Impurity-7) was greater than 2.5. Regression analysis confers an R2 value (correlation coefficient) higher than 0.999 for the active substance and impurities. The detection level for ENZ impurities was at a level below 0.015% (0.12 μg/mL). The accuracy levels for different compounds were close to 100%. The inter- and intra-day precisions for ENZ and impurities were evaluated and their relative standard deviation (%) values were less than 3.5. Our results show that the UPLC-UV stability-indicating method will be an essential tool that could determine the drug product's impurities and be useful in regular quality control and stability studies of the ENZ drug product dosage form.

Abstract
Chiral stationary phases are conveniently used for enantiomeric separation of drugs by liquid chromatography. Consumption of large volumes of hazardous solvents is considered as a common challenge for the sustainability of this technique. To this end, a columnar chromatography has been adopted using 50-mm-length stationary phases. The study comprised five Phenomenex Lux cellulose- and amylose-based columns for the separation of guaifenesin (GUA) enantiomers. In addition, an experimental design was used to optimize the gradient profile for the separation of racemic GUA and ambroxol HCl (AMB) binary mixture. The chromatographic method was achieved using Lux Cellulose-1 (50 × 4.6 mm) as a chiral stationary phase and ethanol/water as a mobile phase with linear gradient elution of 20% to 70% ethanol in 6 minutes at a flow rate of 1.0 mL min-1 and UV detection at 270 nm. Linearity ranges were found to be 50 to 1000 μg mL-1 and 15 to 450 μg mL-1 for each GUA enantiomer and AMB, respectively. Environmental, health and safety tool was used to assess and compare greenness of the proposed and reported methods. Short column indeed reduces the environmental impact by decreasing waste by about 60% and utilizing only 1-mL ethanol in the mobile phase. The proposed method is a safer alternative for the simultaneous determination of drugs in their combined pharmaceutical formulation. The method has been validated and compared favorably with a reported one.

Abstract
OBJECTIVE The objective of the present work was to develop and validate a simple, sensitive, rapid and stable reverse-phase high performance liquid chromatography (RP-HPLC) method for a combination of Terbutaline sulphate (TSL), Ambroxol hydrochloride (AML) and Guaifenesin (GFN). METHOD The combination of these drugs was analyzed by using Shimadzu LC 2010 CHT high performance liquid chromatography (HPLC). Successful separation was achieved by isocratic elution on a reverse-phase C18 column (sun fire) (250mm, 4.6mm, 5μ), using a mobile phase consisting of buffer: acetonitrile in the ratio 80: 20 (buffer - 0.1% v/v triethyleamine pH-3.0) followed by 1.0mL/min flow rate. The wavelength of detection was at 220nm. RESULT The chromatographic retention times were consistent at 3.0, 10.5 and 13.8minutes for TSL, AML and GFN respectively. For these three compounds, the lower limit of detection was 1.0, 1.25, and 1.5μg/mL and lower limit of quantification was 3.3, 4.1 and 5.0μg/mL respectively. The linearity concentrations established for TSL, AML and GFN were 1.0-7.0, 1.5-7.5 and 4.0-14.0μg/mL respectively. The correlation coefficients for all the drugs were found to be greater than 0.999. The relative standard deviation of inter- and intra-day were less than 2.0%. CONCLUSION This method provides a necessary tool for quantification of the selected drugs for their assay. The proposed method is simple, accurate, reproducible and applied successfully to analyze three compounds in pure as well dosage form.

Multivariate calibration models manipulating UV-spectroscopic data of three anti-productive cough drugs namely ambroxol, guaifenesin and theophylline were constructed for the intent of simultaneous determination in presence of their impurities; guaiacol and caffeine. Both interval partial least squares (iPLS) and synergy interval partial least square (siPLS) algorithms were adopted for variables selection to extract useful information and improve the models' performance. The optimal spectral range and their combinations were assigned according to the lowest value of Root Mean Square Error of Prediction (RMSEP), Standard Error of Prediction (SEP) and Correlation Coefficient (R2). The results obtained from full spectrum PLS were compared with those obtained by iPLS and siPLS. The siPLS method exhibited better performance. The combination of four subintervals, 2, 9, 13, and 16, showed the best effect, with RMSEP of 0.1039, 0.3548 and 0.207 μg/mL, for ambroxol, guaifenesin and theophylline, respectively and correlation coefficient of 0.9999, 0.9975 and 0.9994 for ambroxol, guaifenesin and theophylline, respectively. The proposed methods were used for the simultaneous determination of the three drugs in presence of their impurities in bulk powder and in pharmaceutical formulation.

Abstract
Green chemistry and sustainability is now entirely encompassed across the majority of pharmaceutical companies and research labs. Researchers' attention is careworn toward implementing the green analytical chemistry principles for more eco-friendly analytical methodologies. Solvents play a dominant role in determining the greenness of the analytical procedure. Using safer solvents, the greenness profile of the methodology could be increased remarkably. In this context, a green chromatographic method has been developed and validated for the simultaneous determination of phenylephrine, paracetamol, and guaifenesin in their ternary pharmaceutical mixture. The chromatographic separation was carried out using monolithic column and green solvents as mobile phase. The use of monolithic column allows efficient separation protocols at higher flow rates, which results in short time of analysis. Two-factor three-level experimental design was used to optimize the chromatographic conditions. The greenness profile of the proposed methodology was assessed using eco-scale as a green metrics and was found to be an excellent green method with regard to the usage and production of hazardous chemicals and solvents, energy consumption, and amount of produced waste. The proposed method improved the environmental impact without compromising the analytical performance criteria and could be used as a safer alternate for the routine analysis of the studied drugs.
