“…The accuracy of the models was estimated mainly by RMSEP (root mean square of prediction) [24,25]. PLSR model showed better accuracy than the univariate model with RMSEP values of 2.35% (v/v), indicating that the method provided results that agree with those in the reference values (Table 2).…”

“…The results obtained from the analysis of commercial tablets were compared statistically with those obtained from the USP 26 high-performance liquid chromatographic (HPLC) method. 3.3 Spectrophotometric method 3.3.1 Diffuse reflectance near infrared spectroscopy Marcus H. Ferreira et al [17] developed and validated a new multivariate diffuse reflectance near infrared method for direct determination of Hydrochlorothiazide in powder pharmaceutical samples. The best partial least squares (PLS) model was obtained in the spectral region from 1640 to 1780 nm, with mean centered data pre-processed by first derivative and Savitzky-Golay smoothing followed by vector normalization.…”

Hydrochlorothiazide is chemically 6-chloro-1, 1-dioxo-3, 4-dihydro-2H-1, 2, 4-benzothiadiazine-7-sulfonamide. Hydrochlorothiazide is a diuretic drug used for treatment of high blood pressure (hypertension) and accumulation of fluid (edema). It works by blocking salt and fluid reabsorption from the urine in the kidneys, causing increased urine output (dieresis). Hydrochlorothiazide is used to treat excessive fluid accumulation and swelling (edema) of the body caused by heart failure, cirrhosis, chronic kidney failure, corticosteroid medications, and nephrotic syndrome. It can be used alone or in conjunction with other blood pressure lowering medications to treat high blood pressure.This review focuses on the recent developments in analytical techniques for estimation of Hydrochlorothiazide alone or in combinations with other drugs in various biological media like human plasma and urine. This review will critically examine the (a) sample pretreatment method such as solid phase extraction (SPE), (b) separation methods such as thin layer chromatography (TLC), high performance liquid chromatography (HPLC), ultra performance liquid chromatography (UPLC), high performance thin layer chromatography (HPTLC), liquid chromatography coupled to tandem mass spectrometry (LC-MS) and capillary electrophoresis (CE), (c) other methods such as spectrophotometry, diffuse reflectance near infrared spectroscopy and electrochemical methods.

“…By applying a three-factor (API, saccharose, and other excipients) experimental design, the concentration of factors was varied orthogonally [27]. Ferreira et al used a calibration set prepared according to a DoE with three factors: hydrochlorothyazide, cellulose, and other excipients to train a NIR method for the quantification of the active ingredient in pharmaceutical samples [28].…”

Vibrational spectroscopy, namely near infrared (NIR) and Raman spectroscopy, is based on the interaction between the electromagnetic radiation and matter. The technique is sensitive to chemical and physical properties and delivers a wide range of information about the analyzed sample, but in order to extract the information, multivariate calibration of the spectral data is required. The main goal of this work will be to present in detail the available multivariate calibration strategy for development of NIR and Raman spectroscopic methods, which was successfully applied in pharmaceutics.
