Objective: The objective of this review is to put a light on the development of lamotrigine and its active pharmaceutical ingredients formulation with proper demonstration. Method: In the present work, one of the most imperative spectrophotometric method which is RP-HPLC method has been developed for the quantitative estimation of lamotrigine in bulk and pharmaceutical formulations. UV spectrophotometric method which involves the determination of Lamotrigine in bulk and in bulk drug and pharmaceutical formulation has maximum absorption at 307.5nm in methanol. It obeys Beer’s and Lambert’s law in the concentration range of 5-45 µg/ml. A rapid and sensitive RP- HPLC Method with UV detection (270 nm) for routine analysis of Lamotrigine formulation was developed. Chromatography was performed with mobile phase containing a mixture of methanol and Phosphate buffer (65:35v/v) with flow rate 1.0 ml/min. In the range of 20-100 µg/ml, the linearity of lamotrigine shows a correlation co-efficient of 0.9998. The proposed method was validated by determining sensitivity and system suitability parameters.

Key Variables

A highly specific, accurate, and simple RP-HPLC technique was developed for the real-time quantification of domperidone (DOMP) and lansoprazole (LANS) in commercial formulations. Chromatographic studies were performed using a Luna C8(2), 5 μm, 100Å, column (250 × 4.6 mm, Phenomenex) with a mobile phase composed of acetonitrile/2 mM ammonium acetate (51:49 v/v), pH 6.7. The flow rate was 1 mL·min−1 with UV detection at 289 nm. Linearity was observed within the range of 4–36 µg·mL−1 for domperidone and 2–18 µg·mL−1 for lansoprazole. Method optimization was achieved using Box-Behnken design software, in which three key variables were examined, namely, the flow rate (A), the composition of the mobile phase (B), and the pH (C). The retention time (Y1 and Y3) and the peak area (Y2 and Y4) were taken as the response parameters. We observed that slight alterations in the mobile phase and the flow rate influenced the outcome, whereas the pH exerted no effect. Method validation featured various ICH parameters including linearity, limit of detection (LOD), accuracy, precision, ruggedness, robustness, stability, and system suitability. This method is potentially useful for the analysis of commercial formulations and laboratory preparations.

Abstract A simple, accurate and precise RP-HPLC method was developed for the simultaneous determination of chloroquine, pyrimethamine and cetirizine hydrochloride concentrations in bulk drug and human serum. The assay was performed using a mobile phase of methanol: water (70:30) at pH of 2.8 ± 0.05 on the Purospher C-18 column with UV detection at 230 nm and rosuvastatin used as an internal standard. The retention times observed for chloroquine, pyrimethamine and cetirizine hydrochloride were 3.5, 2.5 and 5.5 minutes, respectively. The method was found to be specific for the assayed drugs showing a linear response in the concentration range of 1–100 μg mL−1 with coefficients of determination values of (r = 0.999). The method was developed and validated according to ICH guidelines. The method was used to monitor the serum samples and was found to be sensitive for therapeutic purposes, showing the potential to be a useful tool for routine analysis in laboratories.

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.

The present study describes the separation and simultaneous estimation of eight anti-retroviral drugs, namely, Telaprevir (TPV), Emtricitabine (ECB), Fosamprenavir (FANV), Tenofavir (TNF), Ritonavir (RNV), Raltegravir (RGV) and Oseltamivir (OSMV) and Zidovudine (ZDV) as an active pharmaceutical ingredient, by RP-HPLC method by applying the principles of Quality by Design (QbD). An application of DoE (Design of Experiments) full factorial design was used for initial screening and optimization. The final optimized method consists of separation being carried out on a Fortis C18 column (150 mm × 4.6 mm, 5μ particle size) using acetonitrile and 10 mm ammonium formate buffer (pH 3 adjusted with formic acid) using a gradient program. The quantitative evaluation was performed with a diode array detector at 251 nm and 230 nm with a flow rate of 1 mL min–1. Suitability of this method for the quantitative determination of the drugs was proved by validation in accordance with the International Conference on Harmonization (ICH) guidelines. The method is selective, precise, robust and accurate and can be used for routine analysis of pharmaceutical formulations in quality control and counterfeit screening.

Abstract Two stability-indicating methods were developed for the determination of candesartan cilexetil in the presence of its degradation products. The first method uses isocratic RP-HPLC with an Agilent C18 column. The mobile phase was phosphate buffer (pH = 2.8 ± 0.1)–acetonitrile (60 + 40, v/v). The flow rate was 2.0 mL/min, and the UV detection was at 254 nm. The second method depends on TLC-densitometric measurements of drug spots at 254 nm. The separation was carried out on silica gel 60 F254 plates using ethyl acetate–methanol–toluene– ammonia 33% (40 + 25 + 20 + 2, v/v/v/v) mobile phase. The methods were validated according to U.S. Pharmacopeia guidelines, and the acceptance criteria for accuracy, precision, linearity, specificity, robustness, LOD, LOQ, and system suitability were met in all cases. Linear ranges of the methods were 10.0–200.0 μg/mL and 1.0–9.0 μg/spot for HPLC and TLC, respectively. The proposed methods were successfully applied to the drug in bulk powder, in laboratory-prepared mixtures with its degradation products, and in commercially available tablets. The results were compared statistically at the 95% confidence level with each other. There were no significant differences between the mean recovery and precision of the two methods.

Identification And Quantification

Andrographis paniculata (Burm. f.) Wall. ex Nees, commonly known as Kalmegh, is widely used as antimalarial drug in herbal and traditional systems. Andrographolide is the major triterpenoid present in the plant and responsible for its therapeutic activities. The identification and quantification of andrographolide were ascertained by various spectrophotometric and chromatographic analyses. The plant sample was extracted with methanol. The amorphous residue obtained from extraction was analyzed for identification of andrographolide by chemical method, TLC, UV-Vis, FT-IR and LCMS/MS analyses. The quantitative estimation of andrographolide content in plant sample was carried out by simple reversed phase HPLC method with C18 column using a mixture of water and methanol (35:65) as mobile phase at a flow rate of 0.7 mL/min, and the estimated concentration level of andrographolide was found as 38.36±0.42 ?g/mL in the solution of amorphous residue (50 ?g/mL). After quantitative determination of andrographolide, standardization of its market preparations was accomplished using the same RP-HPLC method. The estimated % potencies of andrographolide compared to reference standard in six market preparations were found to be 97.56, 98.37, 98.21, 95.60, 98.91 and 96.40.Dhaka Univ. J. Pharm.
