Objective: Cost effective formulation development and stability indicating HPLC method for estimation of apixaban in bulk and tablets dosage form.Methods: 32 factorial design was applied to formulate the immediate release tablets of apixaban by using direct compression method. The chromatographic separation was performed on Purospher Star RP-18e (5 µm, 250x4, 6 mm) column and a stability indicating assay method was developed by using HPLC. The mobile phase consists of water: acetonitrile (60:40 v/v) was delivered at a flow rate of 1 ml/min and UV detection at 280 nm. The method was validated with forced degradation studies as per ICH guidelines.Results: Prepared batches were evaluated for all pre-compression parameters and post-compression parameters. Formulation batch F5 prepared by direct compression shows highest dissolution release of 90.97 % over the period of 60 min while disintegration time was found to be 136 seconds. The retention time of developed HPLC method was found to be 5.66 min. This method was found to be linear in a concentration range of 5-30 μg/ml of the drug (r2= 0.999). The low value of % RSD in the precision study indicates reproducibility of the method. The low value of LOD and LOQ suggests the sensitivity of the method. The results of forced degradation studies indicated that the drug was less stable in thermal and photolytic condition and degraded in acidic, basic, oxidative conditions.Conclusion: On the basis of formulation evaluation, batch F5 was found to be promising formulation suitable for the immediate release of apixaban. Results obtained by validation studies suggested that the developed stability indicating assay method is simple, accurate, specific, sensitive and precise. Thus, this method can be used for routine analysis of apixaban formulation and to check the stability testing.

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 simple, economical, robust and stability-indicating reverse phase high performance liquid chromatography method was developed and validated for the quantification of ropinirole hydrochloride in API and tablets to achieve shorter retention time, to minimize human error by avoiding the use of buffers and weighing procedure and analyze more number of samples in shorter period of time with good accuracy. Methods: The chromatographic conditions for separation of ropinirole hydrochloride was carried out using Gemini NX C18 column (15 cm x 4.6 mm), 5 µm particle size with the mobile phase composing of methanol: acetonitrile (70:30 v/v), delivered at flow rate 0.7 ml/min and UV detection wavelength at 250 nm. Results: The retention time was observed at 2.718 min. The system suitability results were found to be within limits. The method was precise, with lower than 2 %RSD and the calibration curve was linear (r2=1) over a concentration range of 2.5-160 µg/ml. The detection and quantification limit was found to be 0.045 µg/ml and 0.15 µg/ml, respectively. Recovery of the drug was found between 100.09-100.19%. The assay of ropinirole hydrochloride in ROPITOR® and ROPARK® tablets were found to be 100.4 and 103.60 %, respectively. The forced degradation studies were carried out to demonstrate the specificity of the method by exposing the API under conditions of hydrolysis, oxidation, thermal and photolytic as per ICH Q1A(R2) guidelines. Conclusion: The low coefficient of variation and agreeable recovery confirmed that the newly developed method could be employed for routine analysis of ropinirole hydrochloride in API and tablets.

Remogliflozin Etabonate

Abstract Background A sensitive, precise, and stability-indicating high-performance thin-layer chromatographic (HPTLC) method has been developed for the analysis of Remogliflozin etabonate in tablet formulation. HPTLC plates precoated with silica gel 60 F254 were used as the stationary phase; methanol: ethyl acetate: toluene: NH3 (2:4:4:0.1, v/v/v) was used as mobile phase, and densitometry was used for the quantitative estimation of the drug. The proposed method was validated with respect to linearity, accuracy, precision, and robustness and applied for the estimation of drug in tablet dosage form. Results The Rf value of Remogliflozin etabonate was observed to be 0.61. The densitometric estimation was performed in reflectance mode at 229 nm. The method was found to be linear in the range of 500–8000 ng/band for Remogliflozin etabonate. The possible degradation pathway was estimated by performing forced degradation studies. The degradant peaks were well resolved from the drug peak with acceptable resolution in their Rf value. Conclusion An accurate and precise high-performance thin-layer chromatographic method has been developed for the quantification of Remogliflozin etabonate in tablets. Forced degradation studies were performed, and drug was found to be highly susceptible to acid, base hydrolysis, and oxidative stress degradation and gets converted into active drug Remogliflozin. Both Remogliflozin etabonate and Remogliflozin bands were well resolved. The method was applied for the analysis of drug in tablet formulation, and it can be used for routine quality control analysis, as well as for the analysis of stability samples.
