Objective: A basic, powerful and isocratic chiral fluid chromatographic technique was created and approved for the enantiomeric partition of meclizine hydrochloride in pharmaceutical dose structure. Methods: The chromatographic partition was accomplished on Phenomenex® Lux Cellulose 1 (250 mm x 4.6 mm i.d, 5 μm molecule size) section utilizing portable stage framework containing acetonitrile: 25mM ammonium bicarbonate (75:25%v /v). The versatile stage was siphoned on the segment at the stream pace of 1.0 mL/min, and UV recognition was done at 230 nm. Result: The breaking points of recognition and measurement were observed to be 0.25 μg/mL and 1.00 μg/mL individually, for 20μL infusion volume. The alignment bend demonstrated phenomenal linearity over the focus scope of 1-5 μg/mL for (±) meclizine enantiomers with a relationship coefficient (r2 = 0.999). The recuperation investigation of meclizine from tablet plan was observed to be 97.33% and 98.81% separately. Meclizine standard arrangement and versatile stage were observed to be steady for in any event 32h. The meclizine enantiomers were very much settled with mean maintenance times of about (+) Meclizine at 13.14 min and (-) Meclizine at 14.33 min individually. Conclusion: The created technique was broadly approved and demonstrated to be hearty, exact, exact and appropriate for the examination of meclizine enantiomers in tablet measurement structure and security investigations of meclizine.

A simple, sensitive chiral liquid chromatographic method was developed for the separation and quantification of enantiomers Midodrine. A chiral PAK IG-3 (150 x 4.6 mm) 3µm column was used for the separation of the enantiomers. The mobile phase consists of 10 mM ammonium bicarbonate in water and acetonitrile in the ratio of 95:5, v/v with a flow rate of 0.7 ml/min. The detection was done at 290 nm with column temperature maintained at 40°C. The method linear ranged between 10 – 110 μg/ml and 5 – 100 μg/ml for (+) and (-) Midodrine enantiomers.  The recovery of the method was found to be in the range of 99.1 to 101.2 %. The detection limit for the (+) and (-) enantiomers was found to be 4 μg/ml and 1 μg/ml, respectively. A simple validated chiral HPLC method with reverse elusion is described for the separation and quantification of the enantiomers of Midodrine in bulk and formulation.

A simple, accurate and precise stability-indicating RP-HPLC method was developed and subsequently validated for simultaneous determination of ilaprazole and domperidone in bulk and pharmaceutical dosage form. The proposed HPLC method utilizes  C18  (250 mm × 4.6 mm × 5 µm) column with mobile phase comprising of 0.5 % glacial acetic acid in water pH 5.5 adjusted with ammonia solution: methanol in the ratio 45:55 v/v at a flow rate of 1.0 ml/min. Quantitation was achieved with UV detection at 286 nm based on peak area with linear calibration curves at concentration  ranges 80-120µg/ml for ilaprazole and 240-360 µg/ml for domperidone  with correlation coefficient of 0.999.The retention times of ilaprazole and domperidone  were found to be 3.0 min, 5.4 min respectively. The mean recoveries obtained for ilaprazole and domperidone were found to be 99.76 ± 0.6463 % and 100.7 ± 0.2424 % respectively. Stress testing which covered acid, alkali hydrolysis, and peroxide, photolytic, thermal degradation was performed to prove the specificity of the proposed method and degradation was achieved. The proposed method was successfully applied for the stability indicating simultaneous estimation of ilaprazole and domperidone in routine quality control analysis in bulk and pharmaceutical formulation.

Objective: The present study aims at developing an accurate precise, rapid and sensitive Reverse Phase High-Performance Liquid Chromatography (RP-HPLC) method for assessing Empagliflozin in bulk drug and in the pharmaceutical dosage form. Methods: The proposed method employs a Reverse Phase Shim Pack C18 column (250 mm × 4.6 mm id; 5 µm) using a mobile phase comprising of acetonitrile and water in the ratio of 60:40 v/v flushed at a flow rate of 1 ml/min. The eluents were monitored at 223 nm. Results: Empagliflozin was eluted at a retention time of 5.417 min and established a co-relation co-efficient (R2>0.999) over a concentration ranging from 0.0495-100µg/ml. Percentage recovery was obtained between 98-102% which indicated that the method is accurate. The Limit of Detection (LOD) and Limit of Quantitation (LOQ) were found at 0.0125µg/ml and 0.0495µg/ml, respectively. Conclusion: An RP-HPLC method which was relatively simple, accurate, rapid and precise was developed and its validation was performed for the quantitative analysis of empagliflozin in bulk and tablet dosage form (10 and 25 mg) in accordance to International Conference of Harmonization (ICH) Q2 (R1) guidelines. The proposed method may aid in routinely analyzing empagliflozin in pharmaceuticals.

A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.
