Development And Validation

A simple, rapid, accurate, and precise gradient reversed-phase HPLC (RP-HPLC) method has been developed for the determination of ganciclovir (GNC) in pharmaceuticals. Chromatographic separation was carried out on inertsil ODS C18 (4.6 mm  mm, 5.0 μm) LC column using ammonium acetate buffer, sodium salt of hexane sulfonic acid as ion-pairing reagent in 1000 mL water, and acetonitrile (90 : 10) (v/v) as mobile phase at a flow rate of 1.0 mL  and with UV detection at 245 nm at column temperature (30°C). The runtime under these chromatographic conditions was 10 min. The method was linear over the range of 0.02–75 μg . The limits of detection (LOD) and quantification (LOQ) values were 4.1 and 20 ng , respectively. The method was successfully extended to study the effect on GNC upon treatment with 2 N NaOH, 2N HCl, and 5% H2O2 for 2 hrs at 80°C and upon exposure to UV (1200 K lux hrs) for 72 hrs and thermal (105°C) for 5 hrs. The proposed method was further applied to the determination of GNC in pharmaceuticals, with good percent recovery. The accuracy and the precision of the method were validated on intraday and interday basis in accordance with ICH guidelines.

Flibanserin has been recently approved by the USFDA for treating female sexual interest disorder. It is currently not included in any of the Pharmacopoeias. No stability indicating method information about flibanserin has been reported in the literature. Flibanserin stock solution (1 mg/mL) was prepared and serially diluted (concentration ranged 1-20 μg/mL). Flibanserin solutions (1-20 μg/mL) were analysed using RP-HPLC under isocratic elution of mobile phase acetonitrile and ammonium acetate (60:40; V/V) at 1 mL/minute. This HPLC method was validated for linearity, accuracy, precision, robustness, limit of detection (LOD) and limit of quantification (LOQ), according to ICH guidelines. Results showed that the method developed has promising linearity (r2= 0.9993), accuracy, precision (0.92-1.61%), robustness, LOD and LOQ. The developed HPLC method for evaluation of flibanserin was found reliable, precise, sensitive, accurate and repeatable for routine analysis and quality control of flibanserin. It is suitable to be used as stability indicating method in pharmaceutical analysis.

The combination of the powerful antimicrobial agent florfenicol and the nonsteroidal anti-inflammatory flunixin meglumine is used for the treatment of bovine respiratory disease (BRD) and control of BRD-associated pyrexia, in beef and nonlactating dairy cattle. This study describes the development and validation of an HPLC-UV method for the simultaneous determination of florfenicol and flunixin, in an injectable preparation with a mixture of excipients. The proposed RP-HPLC method was developed by a reversed phase- (RP-) C18e (250 mm × 4.6 mm, 5 μm) column at room temperature, with an isocratic mobile phase of acetonitrile and water mixture, and pH was adjusted to 2.8 using diluted phosphoric acid, a flow rate of 1.0 mL/min, and ultraviolet detection at 268 nm. The stability-indicating method was developed by exposing the drugs to stress conditions of acid and base hydrolysis, oxidation, photodegradation, and thermal degradation; the obtained degraded products were successfully separated from the APIs. This method was validated in accordance with FDA and ICH guidelines and showed excellent linearity, accuracy, precision, specificity, robustness, LOD, LOQ, and system suitability results within the acceptance criteria.

Shimadzo Prominance model L20 AD HPLC system equipped with SPD 20A UV-Vis detector was used for the analysis. The separation was done on RESTEX allure C18 column (3 μm, 15 cm × 4.6 mm), for an isocratic elution a mixture of methanol and water (60:40, v/v) mobile phase at a wavelength of 254 nm. The flow rate was 1.0 mL/min. The RP-HPLC method developed for analysis of norfloxacin was validated with respect to specificity, selectivity, linearity, accuracy, precision and robustness as per the ICH guidelines. The retention time of norfloxacin was 7.5 min. The linearity was established over the concentration ranges of 50-350 μg/mL with correlation coefficients ( r2) 0.999.  The percentage accuracy of norfloxacin ranged from 99.76 -101.66%. The relative standard deviation values for intra-day and inter-day precision was lower than 2.0% and the assay result was found to be 100.65 %. Norfloxacin was subjected to stress conditions such as neutral, acidic, alkaline, oxidation and photolysis degradations as per ICH guidelines. The degradation studies revealed that the drug was found to degrade maximum (1.67%) in alkaline degradation conditions and was highly resistant towards neutral, acidic, oxidative and photolytic degradation conditions.
