Tadalafil is a selective phosphodiesterase Type 5 enzyme inhibitor. Simple and sensitive High Performance Thin - Layer Chromatography (HPTLC) and Reversed - Phase High - Performance Liquid Chromatography (RP-HPLC) methods have been developed for estimation of tadalafil in pharmaceutical dosage form. Separation of tadalafil was achieved on HPTLC aluminum sheets of silica gel 60 F254 with mixture of toluene: methanol (7.2: 2.8 V/V) as the mobile phase. tadalafil obeyed linearity in the concentration range of 300 - 800 ng/band with correlation coefficient (r2) 0.9994. Detection was performed densitometricaly at 284 nm with Rf 0.50 ± 0.02. RP-HPLC separation was achieved using Qualisil C18 column on mixture of methanol: water (75: 25 % V/V) as the mobile phase. Linearity was plotted in range of 2 – 12 μg/mL and (r2) value as 0.9998. The retention time was found to be 4.82 ± 0.02 min. The developed HPTLC and RP-HPLC methods have been successfully applied for the determination of tadalafil in bulk and pharmaceutical formulation. Both these methods were statistically compared.

A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.

AbstractTh accurate rapid, simple and selective reversed phase high performance liquid chromatography (RP-HPLC) has been established and validated for the determination of captopril (CAP). Chromatographic separation was accomplished using prepacked ODSI C18 column (250 mm × 4.6 mm with 5 μm particle size) in isocratic mode, with mobile phase consisting of water: acetonitrile (60:40 v/v), pH adjusted to 2.5 by using 85% orthophosphoric acid at a flow rate of 1 mL/min and UV detection was performed at 203 nm. RP-HPLC method used for the analysis of CAP in mobile phase and rabbit plasma was established and validated as per ICH-guidelines. It was carried out on a well-defined chromatographic peak of CAP was established with a retention time of 4.9 min and tailing factor of 1.871. The liquid–liquid extraction method was used for extraction of CAP from the plasma. Excellent linearity (R2 = 0.999) was shown over range 3.125–100 µg/mL with mean percentage recoveries ranges from 97 to 100.6%. Parameters of precision and accuracy of the developed method meet the established criteria. Intra and inter-day precision (% relative standard deviation) study was also performed which was less than 2% which indicate good reproducibility of the method. The limit of detection (LOD) and quantification for the CAP in plasma were 3.10 and 9.13 ng/mL respectively. The method was suitably validated and successfully applied to the determination of CAP in rabbit plasma samples.

Rabeprazole Sodium

A rapid, simple and highly sensitive reversed phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitative determination of Rabeprazole sodium and Aceclofenac in a combined dosage form. Rabeprazole sodium and Aceclofenac were chromatographed using C-18 column as stationary phase and methanol: acetonitrile: water (60 : 10 : 30 v/v/v) as the mobile phase at a flow rate of 1.0 ml/min at ambient temperature and detected at 280 nm. The retention time (RT) of Rabeprazole sodium and Aceclofenac were found to be 5.611 min and 2.102 minute, respectively. The linearities of Rabeprazole sodium and Aceclofenac were in the range of 1-10 µg/ml and 3-15 µg/ml, respectively. The limit of detection was found to be 0.091 µg/ml for Rabeprazole sodium and 0.043 µg/ml for Aceclofenac. The proposed method was applied for the determination of Rabeprazole sodium and Aceclofenac in a combined dosage form and result was found satisfactory.DOI: http://dx.doi.org/10.3329/icpj.v1i12.12450 International Current Pharmaceutical Journal 2012, 1(12): 410-413

Abstract An accurate and precise RP-HPLC method was developed and validated for the determination of carbamazepine and its impurities iminostilbene and iminodibenzyl in a tablet formulation with fluphenazine as an internal standard. Buffermethanol (50 + 50, v/v) was used as the mobile phase. During validation, specificity, linearity, precision, accuracy, LOD, LOQ, and robustness of the method were tested. The method was proven to be specific against placebo interference. Linearity was evaluated over the concentration range of 100500, 0.050.25, and 0.10.5 g/mL, and the r values were 0.9994, 0.9997, and 0.9979 for carbamazepine, iminostilbene, and iminodibenzyl, respectively. Intraday precision of the method was good, and RSD was below 2 for all analytes. The accuracy of the method ranged from 100.69 to 102.10, 99.76 to 102.66, and 99.26 to 100.08 for carbamazepine, iminostilbene, and iminodibenzyl, respectively. LOD was 0.0125, 0.025, and 0.05 g/mL and LOQ was 0.05, 0.05, and 0.1 g/mL for carbamazepine, iminostilbene, and iminodibenzyl, respectively. Robustness of the method was proven by using a chemometric approach. The method was successfully applied to the analysis of commercially available carbamazepine tablets and showed good repeatability, with RSD below 2.

Delamanid is successfully used for treatment of MDR TB. A stability indicating analytical method has been developed and validated. In this study Delamanid was degraded under different stress test conditions as per International Conference on Harmonization. The degraded samples were used to develop a stability-indicating high performance liquid chromatographic (HPLC) method for the Delamanid. The Delamanid was well separated from degradation products using a reversed-phase Hypersil BDS C18 (250 mm × 4.6mm i.d., 5µm) column and a mobile phase comprising of 0.01M pH 2.70 Phosphate Buffer: Acetonitrile (pH 3.50) 70:30, pH of mobile phase was adjusted with Glacial acetic acid and other HPLC parameters were flow rate 1 mL/min, detection wavelength 254 nm and injection volume 10 µl. The method was validated for linearity, precision, accuracy, ruggedness and robustness. Results obtained after validation study indicating that the proposed single method allowed analysis of Delamanid in the presence of their degradation products formed under a variety of stress conditions. The developed procedure was also applicable to the determination of stability of the Delamanid in commercial pharmaceutical dosage form.
