Objective: To develop an accurate, simple, precise and specific stability indicating RP-HPLC method for estimation of dimethyl fumarate in bulk and capsules.Methods: An Inertsil ODS (150x4.6 mm, 5µ) column and a mobile phase containing acetonitrile: potassium dihydrogen phosphate buffer pH 6.8 (50:50% v/v) was used for this study. The flow rate was maintained at 1.0 ml/min; column temperature was fixed at 35 °C and UV detection was carried out at 210 nm. The forced degradation studies were performed and method was validated with as per ICH guidelines.Results: The retention time of dimethyl fumarate was found to be 3.3±0.02 min. The value of correlation coefficient between peak area and concentration was found to be 0.9993. The mean percent recovery of dimethyl fumarate in capsules was found in the range of 99.65 to 101.64%. The results of forced degradation studies indicated that the drug was found to be stable in basic, oxidative and thermal conditions while degraded in acidic conditions.Conclusion: It can be conducted from results that the developed HPLC method is simple, accurate, precise and specific. Results of stress testing study revealed that the method is stability indicating. Thus, this method can be used for routine analysis of dimethyl fumarate capsules and check their stability.

A simple, specific, accurate, and precise RP-HPLC method was developed and validated for the simultaneous estimation of Metoprolol Succinate and Olmesartan Medoxomil in pharmaceutical formulation with forced degradation studies. The method was developed using Enable C 18G column (250 ×4.6 mm, 5 μm) with mobile phase consisting of methanol and water (pH adjusted to 3.5 with orthophosphoric acid in the ratio of 80: 20 % v/v with a flow rate of 1 mL/min. The UV detection was carried out at 240 nm. The retention time for Metoprolol Succinate and Olmesartan Medoxomil were found to be 3.986 and 6.092 min, respectively. The proposed method was validated for linearity, range, accuracy, precision, robustness, LOD, and LOQ. Linearity was observed over a concentration range 4-40 μg/mL for Metoprolol Succinate (r2 = 0.9999) and 5-60 μg/ml for Olmesartan Medoxomil (r2 = 0.9999). The % RSD for Intraday and Interday precision was found to be 0.57 and 0.68 for Metoprolol Succinate and 0.52 and 0.41 for Olmesartan Medoxomil. The LOD and LOQ were found to be 0.1143 μg/mL and 0.3565 μg/mL for Metoprolol Succinate and LOD and LOQ were found to be 0.0563 and 0.1782 μg/mL for Olmesartan Medoxomil respectively.

The concept of Quality by design (QbD) has recently gained importance in the area of analytical method development and involves understanding of the critical factors and their interaction effects by a desired set of experiments. So, the present work describes the development of Reverse Phase-High Performance Liquid Chromatography (RP-HPLC) method by QbD approach using Design of Experiments and subsequent validation for analysis of Vildagliptin in bulk drug and its pharmaceutical formulation. An efficient experimental design based on systematic scouting of all three key components of the RP‐HPLC method (Buffer pH, Organic Phase-% acetonitrile, Organic Modifier-Methanol) is presented. The significance and interaction effects of these parameters on the response variables (Retention time and tailing factor) were evaluated through statistical analysis tools like Analysis of Variance (ANOVA) and plots which revealed the final chromatographic conditions of the method. The developed method was validated and Forced degradation studies were also carried out in order to determine the stability-indicating nature of the method. The chromatographic separation was achieved on Jasco CrestPack RP C18 (250 × 4.6 mm, 5μ) column using Buffer (pH 6): Acetonitrile: Methanol (70:10:20 v/v) as mobile phase and detection was done using Photo-Diode Array (PDA) detector at 210 nm. The developed method of Vildagliptin is linear over a range of 5-15μg/ml having correlation coefficient R2 value as 0.999. The %RSD for precision and accuracy of the method was found to be less than 2%. Forced Degradation studies revealed that the method was found to be stability-indicating. The results showed that the proposed method is suitable for the precise and accurate determination of Vildagliptin in bulk and its formulation.

Objective: A stability indicating reverse phase high-performance liquid chromatography (RP-HPLC) method was developed and validated for the estimation of the combined tablet formulation of lamivudine (LAM) and raltegravir (RAL) in dosage forms and its API.Methods: Chromatographic separation was achieved on inertsil ODS C18 5 µm (4.6 X 150 mm) using a mobile phase (MP) consisting of a mixture of mixed orthophosphoric acid (OPA): acetonitrile (ACN) in the ratio 50:50 v/v which was determined at 242 nm respectively. Results: The assay of LAM and RAL was performed with tablets, and the % assay was found to be 100.12 and 99.89 which shows that the method is useful for routine analysis. The linearity of LAM and RAL was found to be linear with a correlation coefficient of 0.998 and 0.999, which shows that the method is capable of producing good sensitivity. The retention time of LAM and RAL was 1.99 min and 4.34 min respectively; linearity range was found to lie from 15 µg/ml to 75 µg/ml for LAM, 30 µg/ml to 150 µg/ml for RAL with a correlation coefficient of 0.999 respectively. Forced degradation studies were conducted in acidic, basic, thermal, photolytic and peroxide where all the degradation peaks were monitored.Conclusion: The proposed HPLC method was found to be simple, specific, precise, accurate, rapid and economical for simultaneous estimation of LAM and RAL in bulk and tablet dosage form. Thus the validated economical method was applied for forced degradation study of LAM and RAL tablet.
