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.

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.

The new stability-indicating high performance liquid chromatography (HPLC) method has been developed and validated with different parameters for atenolol (ATE) and nifedipine (NIFE) in the combined dosage form. The chromatographic conditions were optimized using a mobile phase of MeOH:OPA (70:30) with a flow rate of 0.7 mL/min. Column (C18) of 4.6 × 250 mm dimension was used as a stationary phase; the particle size capacity of the column was 5 μm. The detection was carried out at 233 nm. The method was validated according to ICH guidelines for linearity, precision, repeatability, the limit of detection (LoD), and limit of quantitation (LoQ). The response was found to be linear in the concentration range of 20 to 100 mcg/mL for ATE and 1 to 5 mcg/mL for NIFE. The developed method shows the minimum quantity of drugs to be identified (LoD) and minimum drug to be quantified (LoQ). The LoD and LoQ were found to be 0.1415 and 0.4289, respectively, for ATE, and 0.1834 and 0.5558, respectively, for NIFE. The method was linear, simple, precise, and accurate and, therefore, suitable for routine analysis of drugs in tablet form. The forced degradation studies were also done through the exposure of analyte solution to four different stress conditions.

Abstract An ultra-high performance liquid chromatography method for simultaneous determination of tacrolimus impurities in pharmaceutical dosage forms has been developed. Appropriate chromatographic separation was achieved on a BEH C18 column using gradient elution with a total run time of 14 min. The method was applied to analyses of commercial samples and was validated in terms of linearity, precision, accuracy, sensitivity and specificity. It was found to be linear, precise and accurate in the range of 0.05 to 0.6 % of the impurities level in pharmaceutical dosage forms. Stability indicating power of the method was demonstrated by the results of forced degradation studies. The forced degradation study in solution revealed tacrolimus instability under stress alkaline, thermal, light and photolytic conditions and in the presence of a radical initiator or metal ions. The drug was stable at pH 3–5. Solid-state degradation studies conducted on amorphous tacrolimus demonstrated its sensitivity to light, elevated temperature, humidity and oxidation.

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.
