Objective: A simple and sensitive method development and validation for the simultaneous determination of the N-nitrosamine dimethylamine (NDMA) and N Nitrosamine diethylamine (NDEA) in Olmesartan medoxomil (OLM) API and formulations by a tandem mass spectrometer (GC-MS/MS). Methods: Gas chromatography with a programmed oven temperature controller, Elite Wax (30 m × 0.25 mm × 0.5 μm) column, Helium as carrier gas and hyphenated to the tandem mass spectrometer powered with triple quadrupole mass analyzer, and photomultiplier tube detector. The method was validated as per the United States Food and Drug Administration (USFDA) guidelines. Results: With the selected GC-MS/MS conditions, the NDMA and NDEA 0.08 μg/ml (80 ng/ml) and 0.16 μg/ml (160 ng/ml) injected and Rt. for NDMA 5.634 and NDEA 6.516 min, respectively. A linear/range lies in between 0.024 and 0.120 μg/ml and 0.048 and 0.240 μg/ml for NDMA and NDEA with r2 >0.99. The precision, accuracy, and system suitability are established as per USFDA and ICH guidelines, the sensitivity of NDMA limit of detection and limit of quantification 0.08, 0.024 and NDEA 0.16, 0.048. Conclusion: Other nitrosamine impurities are not involved in the determination of NDMA and NDEA in the OLM using GC-MS/MS and the method is simple, sensitive, rapid, accurate, and precise.

The quantity of medication brought into the marketplace is growing each year. Analytical method development is increasingly being introduced into fundamental pharmaceutical research and pharmaceutical analysis practice, taking into account their high sensitivity, accuracy, specificity and expressiveness. Search criteria was analytical method development for medicines from group of ACE inhibitors. Literature survey has been done in range of years 1990-2018 to make the review updated and comprehensive and to show the new approacheches to the development of the methods of analysis ACE inhibitors. The sources were world recognized journals and key words used as filter were angiotensin-converting enzyme inhibitors, captopril, enalapril, method development, spectrophotometry, HPLC, UHPLC. The current review is created with an intended to focus on the advantage of HPLC. Literature survey revealed that a number of methods have been reported for estimation of ACE inhibitors individually or in combination with other drugs. However, there is very few analytical methods reported for the simultaneous analysis of these drugs in a combined dosage formulation by HPLC. In additional, analysis of approaches to the development of the methods of analysis of ACE inhibitors in drugs and biological liquids has been shown that HPLC is the most suitable method for analyses ACE inhibitors in substances, drugs, biological liquids to performe routine analysis of medicines, pharmacokinetic (bioequivalence in vivo), dissolution test for final dosages forms (bioequivalence in vitro, biowaiver procedure).

“…The result formulation was reported in Table 6. Statistical analysis proves that the method is suitable for the analysis of OLME, AMLO, and HCTZ as bulk drug and in the pharmaceutical formulation without any interference from the excipients [26][27][28][29][30][31][32][33][34][35][36][37][38][39] .…”

The endeavor of the present work is to develop a simple, economical, efficient, novel green analytical method for the estimation of Amlodipine besylate, Olmesartan medoxomil and Hydrochlorothiazide in pharmaceutical formulation. Quantification was carried out using an Inertsil CN-3.5 μm (4.6 ×250 mm) column, where the mobile phase consisting of 10 mm Phosphate buffer (pH 3.0) and Acetonitrile (40:60). The flow rate was 1.0 mL/min and the effluent was monitored at 262 nm. The observed linearity was in the range of 5-25 µg/ml for Amlodipine (AMLO), Hydrochlorothiazide (HCTZ) and Olmesartan medoxomil (OLME) with a correlation coefficient of 0.997, 0.999 and 0.999 respectively. The proposed method was validated as per ICH guidelines in terms of linearity, accuracy, precision, robustness, and specificity, the limit of detection and limit of quantification. The method has been applied to Amlodipine, Hydrochlorothiazide and Olmesartan formulation without the interference of excipients of the formulation. INTRODUCTION: Amlodipine Besylate: Amlodipine Besylate (2-[(2-Aminoethoxy) methyl]-4-(2-chlorophenyl)-1, 4dihydro-6-methyl-3, 5-pyridinedicarboxylic acid 3ethyl 5-methyl ester benzene sulfonate). Amlodipine is an L-type calcium channel blocker, which decreases the contraction of action and myosin fibers in the cardiac tissue by decreasing the supply of calcium ions. This results in a significant decrease in blood pressure 1, 4-8. The chemical structure was shown in Fig. 1.
