Simple, sensitive, and rapid stability indicating RP-HPLC method for simultaneous estimation of Pantoprazole and Levosulpiride in pharmaceutical dosage form was developed and validated. The analysis was carried out on Hibar C18 column (250 × 4.6 mm, id, 5µ) and the mobile phase composition was 10 mM ammonium acetate (pH 4.0 adjusted using acetic acid): Acetonitrile in the ratio of 20:80% v/v with a flow rate of 1.0 mL/min at room temperature. The sample injection volume was 20 µL, and eluents of the isocratic elution mode were monitored at 241 nm. The retention time was 3.1 min and 5.2 min for Pantoprazole and Levosulpiride, respectively. The method was linear in the concentration range of 1-7 μg/ml for Pantoprazole sodium with an r2 of 0.9973 and 4-10 µg/ml of Levosulpiride with an r2 of 0. 9961. The LOD and LOQ were found to be 0.05 and 1.5 µg/ml for Pantoprazole and Levosulpiride. The drug stability was assessed under various stress degradation conditions at room temperature for 24 h. In photodegradation, the...

Plant galls are remarkable close associations between plants and insects, in which the plant produces an abnormal growth of tissue in response to a specific stimulus from the attacking insect. The present investigation was undertaken to assess the antioxidant activity as well as the total phenols and ascorbic acid content in in-vivo (normal flower and galled flower) and in-vitro (unorganized static callus cultures) of Crataeva religiosa. Callus cultures (fifteen months old) were grown on MS medium supplemented with NAA (1.0 mg/l) and BAP (0.5 mg/l) using normal and galled flower explants. Antioxidant potential was found to be maximum (89.54%) in galled flower and minimum in normal flower callus (16.58%). Lower IC50 value indicates high antioxidant activity which was maximum in normal flower callus (456.12 ± 0.36) and minimum in galled flower (73.49 ± 0.24). Total phenols and ascorbic acid were also higher in galled tissues as compared to normal flower and in-vitro tissues. These primary findings showed that insect induces higher levels of phenolics and ascorbic acid constituents that...

UPLC is a modern technique which refers to Ultra Performance Liquid Chromatography and enhances in three main areas: Speed, resolution, and sensitivity. In this present study, an accurate and precise UPLC method was developed and validated for the stability indicating assay method to estimate Tezacaftor and Ivacaftor simultaneously in both bulk and tablet dosage form. This method was developed using column HSS C18 (100 × 2.1mm 1.7m) with mobile phase 0.1% OPA Buffer: acetonitrile taken in the ratio 50:50. The flow rate was 0.3 ml/min with an 1 μl injection volume. The effluents were detected at a wavelength of 292 nm using the TUV detector. The method was validated concerning specificity, accuracy, linearity, precision, robustness. The correlation coefficient for Tezacaftor and Ivacaftor were found to be 0.999 and 0.999, respectively. Recovery of Tezacaftor and Ivacaftor in the formulation was found to be 99.97% and 99.65%...

The main objective of the study was to enhance the dissolution of fenofibrate (BCS class II), poorly soluble drug. To improve the solubility of the drug, solid dispersions were prepared by dropping method with PEG 4000 and PEG 6000 in the ratios of 1:1 and 1:2. The formulations were filled into capsules and evaluated for solubility, assay, FTIR, X-ray diffractions, DSC, and in-vitro dissolution. The optimized formulation was compared with the marketed formulation. The optimized formulation D4 (containing PEG 6000 (1:2) by dropping method) showed maximum solubility 0.678 ± 0.07 mg/ml when compared to pure drug (0.018 mg/ml), assay, 98.14 ± 12% and practical percentage yield 95.25 ± 0.17%. In-vitro dissolution studies of the prepared solid dispersions showed release in 60 min whereas D4 formulation released 99.10 ± 0.18% in 30 min when compared to pure drug 27.38 ± 0.10% in 60 min, and a marketed capsule containing micronized fenofibrate (Lipicard) 93.91 ± 0.12% in 30 min. FTIR studies confirmed that there is no interaction between the drug and...

Objectives: To retrospectively determine the prescription pattern of antiepileptic drugs (AEDs), hematobiochemical changes, and associated adverse effects. Methodology: A retrospective observational study was conducted at the Department of Neurology, King Fahad Hospital of the University, Khobar, KSA. Data Collection was through Electronic Health Record. A designed validated form to record demographic characteristics, hematological-biochemical parameters and adverse effects were utilized. Results: 115 patients were recruited. 54 (44%) were female and 64 (56%) were male. Carbamazepine; CBZ (n = 47; 40.9%) and Valproic acid; VPA (n = 32; 27.8%) were the most frequently prescribed antiepileptic drugs (AEDs). While CBZ + VPA (n = 21, 18.3%) was the most frequently prescribed combination. Generalized seizures were more frequently diagnosed (n = 80, 70%) compared to partial seizures (n = 22, 19%). The hematological abnormalities manifested as reduction in levels of Hemoglobulin (Hg), Hematocrit, Mean corpuscular volume (MCV), Mean corpuscular hemoglobin (MCH) with all AEDs, while CBZ treatment was additionally associated with reduction in Mean corpuscular hemoglobin concentration (MCHC). The combination of CBZ +...
