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.

A sensitive stability-indicating high performance liquid chromatography (HPLC) method was developed and validated for quantitative estimation of satranidazole (SAT), a new nitroimidazole with potent antiamoebic activity and accessible in market as tablet and dry syrup either alone or in combination with ofloxacin. The present study involves the development of simple, accurate, precise, reproducible reversed phase high performance liquid chromatography (RP-HPLC) method for determination of satranidazole from its formulation. Isocratic elution at a flow rate of 1.0 mL/min was employed on Hemochrom Intsil C-18 (250 mm× 4.6 mm, 5 ?m) column at 25°C. The mobile phase consists of acetonitrile: double distilled water (DDW), pH 4 adjusted with acetic acid in the ratio of 90: 10 V/V. The UV detection wavelength was 320 nm, and 20 ?L sample was injected. The retention time for SAT was about 3.9 minutes. Forced degradation studies for stability-indicating method (SIM) were conducted as per the presented conditions of ICH guidelines. The drug showed instability in alkaline and oxidation condition while it remained stable in heat, acid and photolytic conditions. According to ICH guidelines, the developed method was validated for the following parameters: linearity, accuracy, precision, specificity, robustness, limit of detection (LOD) and limit of quantification (LOQ). The method was found to be accurate, linear, precise, robust, economical and stability-indicating for analysis of the drug as well as marketed formulation.

Objective: This study aimed to validate an high-performance liquid chromatography method for analyzing undenatured Type II collagen preparationsusing a fluorescence detector.Methods: Based on the optimum analysis conditions, the compound was detected at an excitation wavelength of 255 nm and an emission wavelengthof 320 nm. The optimum mobile phase was determined to be acetate (pH 4.2) and acetonitrile (60:40) with a flow rate of 1.0 ml/min. Hydroxyprolineis a compound that does not have chromophore moiety; thus, it has to be derivatized first using 9-fluorenylmetoxycarbonyl-chloride.Results: The developed method was validated with linearity and an equation of y=3,249,704 x+141,945,072, with a value of r=0.9994. The detectedrange of hydroxyproline was 4–15 ppm. The limit of detection was determined to be 0.49, with an limit of quantitation of 1.64.Conclusion: Our results indicated that the average level of hydroxyproline was 98.66%, 99.12%, and 99.85%.

AbstractThe aim of the study was to design and validate a reversed phase high performance liquid chromatography method for the separation and quantification of two active pharmaceutical ingredients (ciprofloxacin hydrochloride, hydrocortisone) and a preservative (benzyl alcohol) in ear drops. Effective separation of the examined compounds was achieved on a GraceSmart™ RP 18 column (150 mm × 4.6 mm, 5 μm) with gradient elution and a diode array detector. The total assay run time was 25 min. Analytical method validation assays were performed. Validation parameters used for the evaluation were: specificity, linearity, trueness, precision (repeatability and reproducibility), limit of detection and limit of quantitation. Results of the validation procedure (high recoveries, good standard deviations, no interfering peaks at the retention times corresponding to the analytes) confirm that the developed chromatographic method can be applied for routine analysis of ear drops.
