The top objective of any pharmaceutical industry is to produce products of necessary characteristic and quality reliably, in a cost-effective manner. Development of a method is essential for discovery, development, and evaluation of medicines in the pharmaceutical formulation. The main aim of this review article was to check the development and validation of the procedure employed for the medication from the starting of the formulation to the complete commercial batch of product. At the point when an analytical technique is applied to produce outcomes for the quality of medicine associated samples, it is necessary that the outcomes are reliable. In the pharma industry, validation policy is documented for how to perform validation, types of validation and validation policy are complied with the necessities of good manufacturing practice (GMP) regulations. Validation is very important for the effective running of the pharmaceutical firms. At every stage from raw material to the finished, stability, everywhere validation was performed. The method was developed properly, and validation parameters are explained in terms of accuracy, specificity, precision, limit of detection (LOD), limit of quantitation (LOQ), ruggedness, robustness, and system suitability testing with the example of certain drugs. All validation parameters are used in the routine and stability analysis.

Abstract A reverse-phase HPLC (RP-HPLC) method was developed for strontium ranelate using a full factorial, screening experimental design. The analytical procedure was validated according to international guidelines for linearity, selectivity, sensitivity, accuracy and precision. A separate experimental design was used to demonstrate the robustness of the method. Strontium ranelate was eluted at 4.4 minutes and showed no interference with the excipients used in the formulation, at 321 nm. The method is linear in the range of 20–320 μg mL−1 (R2 = 0.99998). Recovery, tested in the range of 40–120 μg mL−1, was found to be 96.1–102.1 %. Intra-day and intermediate precision RSDs ranged from 1.0–1.4 and 1.2–1.4 %, resp. The limit of detection and limit of quantitation were 0.06 and 0.20 μg mL−1, resp. The proposed technique is fast, cost-effective, reliable and reproducible, and is proposed for the routine analysis of strontium ranelate.

Development And Validation

A simple, selective, precise and accurate Gas chromatographic method for determination of Triethyl orthoformate content (Genotoxic impurity) in 5-MIA is reported. The GC method development and validation as per the International Council for Harmonisation (ICH) guidelines Q2(R1). The effective chromatographic separations were achieved on DB-624, 60 m × 0.53 mm ID, with film thickness of 3.0 μm (Fused silica capillary column), Capillary injector temperature of 150°C, and Nitrogen Carrier gas. This method is unique as there is no UV response; hence GC Method was developed for Triethyl orthoformate. The elution was accomplished with the flow rate of 5.0 mL/min and Split Flow of 10 mL/minute. Detection was performed with FID detector (temp. 260°C) and with column oven temperature program. Methods range from limit of quantitation (LOQ) to 150% level with respect to specification concentration limit of impurity is linear and correlation coefficient of impurity is > 0.99. The linearity of Triethyl orthoformate covered from LOQ to 113 ppm (ie. LOQ to 150% of specification limit) and LOQ to 19 ppm wrt standard concentration. The limit of detection (LOD)values were observed were 2.5 ppm and limit of quantitation (LOQ) were 7.7 ppm, respectively. The parameters selected for the method validated were from international conference on harmonization guidelines, Indian pharmacopeia, USP. The percentage recovery from LOQ, 50% ,100% to 150% level of content were 87.70%, 98.60%, 102.25 and 96.59% respectively. The %RSD values were for LOQ to 150% were from 1.64%, 0.89%, 1.78 % and 1.49%. The range was covered from LOQ to 150% of standard concentration. The results of validation parameters were found in the acceptance range. Standard and sample were stable up to 30 h at when stored at room temperature. Also it was quite robust for the small change in method parameter like, change in column oven temperature(± 5 degree). Hence from the above parameter it was concluded that the GC method with FID detector is selective, precise, linear, and robust for simultaneous estimation of Triethyl orthoformate in Drug Substances.

Abstract This paper reported the method development and validation of a gas chromatography with thermal conductivity detector (GC-TCD) method for the measurement of the gaseous products of hydrodeoxygenation (HDO). The method validation parameters include selectivity, precision (repeatability and reproducibility), accuracy, linearity, limit of detection (LoD), limit of quantitation (LoQ), and robustness. The results showed that the developed method was able to separate the target components (H2, CO2, CH4 and CO) from their mixtures without any special sample treatment. The validated method was selective, precise, accurate, and robust. Application of the developed and validated GC-TCD method to the measurement of by-product components of HDO of bio-oil revealed a good performance with relative standard deviation (RSD) less than 1.0% for all target components, implying that the process of method development and validation provides a trustworthy way of obtaining reliable analytical data.

UV spectrophotometry is an analytical technique used routinely for qualitative and quantitative assay due the low cost and reliability during analysis. An simple, efficient, rapid, sensitive, precise and economical UV Spectrophotometric method has been developed for estimation of agomelatine from bulk and pharmaceutical formulation. The method was developed and validated according to International Conference on Harmonization (ICH Q2 R1) guidelines.  The λmax of agomelatine in acetonitrile was found to be 229.6 nm. The analytical method validation parameters linearity, precision, accuracy, robustness were studied according to International Conference on Harmonization guidelines. Pure drug concentration was prepared in the range of 1-10 μg/ml and the linear regression analysis data showed good linear relationship with correlation coefficient value 0.9937. The precision of the method was studied as an intra- day, inter-day variations with value less than 2 % RSD. The limit of detection and limit of quantitation were found to be 0.577 and 1.248 μg/ml, respectively. Recoveries were found to be in the range of 100.815 to 101.744 % and % RSD was less than 2 %. This proposed UV spectroscopic method is simple and suitable for routine analysis. Keywords: Keywords: Agomelatine, Validation, UV Spectrophotometric method

AbstractMethyl malonic acid and branched-chain keto acids are important biomarkers for the diagnosis of cobalamin deficiencies and maple syrup urine disease. We report the development and validation of a HILIC-ESI-MS2 method for the quantification of these organic acids from neonatal urine. The samples were 100 times diluted and analyzed on a ZIC-HILIC column with 25-mM formic acid in water: 25-mM formic acid in acetonitrile (45:55) at a flow rate of 0.8 mL/min with a runtime of only 6 minutes. The method demonstrated a lower limit of detection of 10 ng/mL, Limit of Quantification (LOQ) of 50 ng/mL, linearity of r2 ≥ 0.990 and recoveries of 87–105% for all analytes. The intraday and interday precision CV’s were <10% and 12%, respectively. Extensive stability studies demonstrated the analytes to be stable in stock and in matrix with a percent change within ±15%. The Bland–Altman analysis of the developed method with the gold standard GCMS method demonstrated a bias of 0.44, 0.11, 0.009 and –0.19 for methyl malonic acid, 3-methyl-2-oxovaleric acid, 2-hydroxy-3methylbutyric acid and 4-methyl-2-oxovaleric acid, respectively, proving the methods are comparable. The newly developed method involves no derivatization and has a simple sample preparation and a low runtime, enabling it to be easily automated with a high sample throughput in a cost-effective manner.
