Lumefantrine is an antimalarial agent used to treat acute uncomplicated malaria. It is administered in combination with artemether for improved efficacy. This combination therapy exerts its effects against the erythrocytic stages of Plasmodium spp. and may be used to treat infections caused by P. falciparum and unidentified Plasmodium species, including infections acquired in chloroquine-resistant areas. A reversed-phase high performance liquid chromatography (RP-HPLC) method was developed and validated for the estimation of lumefantrine in bulk drug. The separation was achieved on Thermo C18 analytical column (250 mm × 4.6 mm i.d., 5.0 μm) using 10mM KH2PO4: acetonitrile  (pH adjust 3.0 with OPA) in the ratio 20:80 v/v as mobile phase and at a flow rate of 1.0 ml/min. Detection was carried out using a UV detector at 240nm. The total chromatographic analysis time per sample was about 6.0 min with lumefantrine eluting at retention time of about 3.225 ± 0.001min. The method was validated for accuracy, precision, specificity, linearity and sensitivity. Validation studies demonstrated that this HPLC method is simple, specific, rapid, reliable and reproducible. The standard curve was linear over the concentration range of 5-25 μg/ml with r2 close to one (0.999). The limit of detection (LOD) and limit of quantitation (LOQ) obtained for lumefantrine were 0.25 μg/ml and 0.75μg/ml respectively. The high recovery and low relative standard deviation confirm the suitability of the proposed method for the determination of lumefantrine in bulk drugs.

Abstract Background A new, sensitive, suitable, clear, accurate, and robust reversed-phase high-performance liquid chromatography (RP-HPLC) method for the determination of brexpiprazole in bulk drug and tablet formulation was developed and validated in this research. Surface methodology was used to optimize the data, with a three-level Box-Behnken design. Methanol concentration in the mobile phase, flow rate, and pH were chosen as the three variables. The separation was performed using an HPLC method with a UV detector and Openlab EZchrom program, as well as a Water spherisorb C18 column (100 mm × 4.6; 5m). Acetonitrile was pumped at a flow rate of 1.0 mL/min with a 10 mM phosphate buffer balanced to a pH of 2.50.05 by diluted OPA (65:35% v/v) and detected at 216 nm. Result The developed RP-HPLC method yielded a suitable retention time for brexpiprazole of 4.22 min, which was optimized using the Design Expert-12 software. The linearity of the established method was verified with a correlation coefficient (r2) of 0.999 over the concentration range of 5.05–75.75 g/mL. For API and formulation, the percent assay was 99.46% and 100.91%, respectively. The percentage RSD for the method’s precision was found to be less than 2.0%. The percentage recoveries were discovered to be between 99.38 and 101.07%. 0.64 μg/mL and 1.95 μg/mL were found to be the LOD and LOQ, respectively. Conclusion The developed and validated RP-HPLC system takes less time and can be used in the industry for routine quality control/analysis of bulk drug and marketed brexpiprazole products.

Anastrozole, an aromatase inhibitor drug, is used for the treatment of breast cancer in pre- and postmenopausal women. Anastrozole’s incorporation into nanoparticulate carriers would enhance its therapeutic performance. To perceive the exact loaded amount of drug in nanocarriers, a valid analytical method is required. The reversed-phase high-performance liquid chromatography (RP-HPLC) method was developed and validated by using the C18 column, 150 × 4.6 mm, 5 µm particle size, in isocratic mobile phase composed of 50:50 V/V (volume/volume) acetonitrile–phosphate buffer (pH 3) flowing at a rate of 1.0 mL/min, and a diode array detector (DAD) set at λmax = 215 nm. The validation parameters such as linearity, accuracy, specificity, precision, and robustness have proven the accuracy of the method, with the relative standard deviation percentage (% RSD) values < 2. The limit of detection of the method was found equal to 0.0150 µg/mL, and the limit of quantitation was 0.0607 µg/mL. The percent recovery of sample was in the range of 98.04–99.25%. The method has the advantage of being rapid with a drug retention time of 2.767 min, specific in terms of resolution of peaks void of interference with any of the excipients, and high reproducibility. This makes it highly applicable for quality control purposes.

Abstract A reverse-phase HPLC (RP-HPLC) method was developed for strontium ranelate using a full factorial, screening experimental design. The analytical procedure was validated according to international guidelines for linearity, selectivity, sensitivity, accuracy and precision. A separate experimental design was used to demonstrate the robustness of the method. Strontium ranelate was eluted at 4.4 minutes and showed no interference with the excipients used in the formulation, at 321 nm. The method is linear in the range of 20–320 μg mL−1 (R2 = 0.99998). Recovery, tested in the range of 40–120 μg mL−1, was found to be 96.1–102.1 %. Intra-day and intermediate precision RSDs ranged from 1.0–1.4 and 1.2–1.4 %, resp. The limit of detection and limit of quantitation were 0.06 and 0.20 μg mL−1, resp. The proposed technique is fast, cost-effective, reliable and reproducible, and is proposed for the routine analysis of strontium ranelate.

This research was aimed to establish a versatile, sensitive, rapid and validated RP-HPLC method to analyze linagliptin in bulk as well as in pharmaceutical dosage forms. Liquid chromatography was performed on HPLC system and 20μl of samples were injected into a C18 column (150 x 4.6 mm i.d., 5μm particle size) and the eluents were monitored through a PDA detector at 239 nm. An isocratic method with a flow rate of 1 ml/min was used to elute the compounds with a mobile phase comprised of 70:30 v/v mixture of phosphate buffer (pH 6.8±0.2) and acetonitrile. The retention time of the compound was found to be 2.8 minutes. According to the ICH Q2(R1) guidelines, the method was validated by establishing several analytical parameters such as system suitability, specificity, linearity, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), ruggedness and robustness to assay linagliptin. The method showed good linearity (R2 = 0.9981) over the concentration ranges of 40 – 60 μg/ml with a recovery between 99.48% ± 0.38% RSD to 100.22% ± 0.011% RSD, whereas the LOD and LOQ values were 0.05 μg/ml and 0.15 μg/ml, respectively. The relative standard deviation (% RSD) for inter-day and intra-day precision was not more than 2.0%. Hence, the proposed method can be applied accurately for research and routine analysis of linagliptin in bulk as well as different pharmaceutical dosage forms. Dhaka Univ. J. Pharm.

A simple, reproducible and efficient reversed phase high performance liquid chromatographic (RPHPLC) method has been developed for the estimation of a recently approved anti allergic drug, amlexanox in oral paste dosage form. The separations were carried out on a Zorbax Eclipse XBD, C18 column (150 x 4.6 mm; 5?m) at a flow rate of 1.50 ml/min. by using mobile phase comprising of mixed buffer (pH adjusted to 6.50) and methanol (50:50 v/v). The injection volume was 10 ?l and the peaks were detected at 244 nm. The linear dynamic range found to be in the concentration range of 15-35 ?g/ml and coefficient of correlation was found to be 0.999. The %RSD value was below 2.0 for intra-day and inter-day precision which indicated that the method was highly precise. The LOD (Limit of detection) and LOQ (Limit of quantitation) were found to be 3.8 ng/ml and 12.5 ng/ml, respectively which revealed that the method was highly sensitive. The percentage recovery of amlexanox ranged from 99.31 to 99.75%, indicating the accuracy of the method and absence of interference from the excipients present in the formulation. The proposed method was simple, fast, accurate and reproducible and hence can be applied for routine quality control operations of amlexanox in oral paste dosage form.
