A new isocratic HPLC method based on reverse phase separation has been developed for simultaneous estimation of Dextromethorphan hydrobromide (DMP), Triprolidine hydrochloride (TPN), and Phenylephrine hydrochloride (PHE) in their mixed liquid dosage form. The chromatographic separation was accomplished on Agilent TC-C18 (250 x 4.6 mm, 5× m) column with a flow rate of 1 ml/min, UV detection (271 nm). Mobile phase consisting of 5 g DOSS, methanol, tetrahydrofuran, and water in the ratio of (70:10:20) pH 4.0 adjusted by acetic acid. The method was found to be selective for PHE, TPN, and DMP with retention time 4.7 min, 5.9 min, and 6.9 min, respectively. The linearity was established over the concentration range of 160-240 mcg/ml, 40-60 mcg/ml and 320-480 mcg/ml for PHE, TPN and DMP, respectively. Limit of detection and Limit of quantification for PHE was found to be 37.87 μg/ml, and 114.77 μg/ml, respectively, for TPN was found to be 10.19 μg/ml and 30.89 μg/ml, respectively and for DMP was found to be 57.50μg/ml and 174.26 μg/ml, respectively....

Objective: To assess the anti-oxidant activity of different seaweed extract. Methods: Different seaweeds as Sargassum wightii, Turbinaria ornata, Gracilaria corticata and Gelidiella acerosa were collected from Mandapam, Ramanathapuram District, Tamil Nadu, India and assessed for their suitability as anti-oxidant compounds. Seaweeds were cleaned from epiphytes, washed, dried in shade and powdered. Algae extractions were performed using different solvents such as methanol, ethanol and hexane. Anti-oxidant potential of marine algal polyphenol from methanol, Ethanol and Hexane extract(s) of seaweed were determined using different method as DPPH radical scavenging assay, Ferric reducing anti-oxidant property (FRAP), Ferrous Ion Chelating Activity (FICA), Reducing power, Total Anti-oxidant Capacity (TAC). The total phenolic content from different seaweeds considered for its anti-oxidant activity. Results: The DPPH radical scavenging activity in methanol extract of brown seaweed Turbinaria ornata (83.8%) is most noteworthy. In Gracilaria corticata it was 79.07 % in ethanol extract. In Sargassum wightii brown seaweed, high activity in methanol and ethanol extracts (75.51% and 70.16%) respectively were observed. The DPPH activity in ethanol extract of...

A simple, reliable, accurate and precise method was developed for the simultaneous estimation of Fexofenadine and Montelukast in pharmaceutical dosage form. The chromatogram was run through Standard HSS C18 (2.1 × 100 mm, 1.8 µm). Mobile phase employed was 0.1% OPA Buffer and Acetonitrile taken in the ratio of 65:35 was pumped through column at a flow rate of 0.2 ml/min. The temperature was maintained at 30 °C. The optimized wavelength selected was 269 nm. The retention time of Montelukast and Fexofenadine was found to be 0.921 and 1.101 min. The Percent RSD of the Montelukast and Fexofenadine were and found to be 0.7% and 0.4% respectively. The Percent recovery was obtained as 99.22% and 99.67% for Montelukast and Fexofenadine respectively. The LOD and LOQ values obtained from regression equations of Montelukast and Fexofenadine were 0.06, 0.18 and 0.80, 2.44 respectively. Regression equation of Montelukast was y = 6333.8x + 755.96 and y = 4038.3x + 8964.8 of Fexofenadine. The decrease in the retention and run times in this...

Poor aqueous solubility has been one of the major challenges in modern drug delivery as it hinders the absorption process leading in the decrease of bioavailability. As a consequence of low water solubility of drugs, low oral bioavailability is a growing challenge to the development of new pharmaceutical products. There has been a consistent increase in the number of new pharmacologically active lipophilic compounds that are poorly water-soluble. Approximately 40% of new drug candidates are lipophilic and exhibit poor water solubility. One of the popular approaches of oral bioavailability and solubility enhancement is the utilization of lipid-based drug delivery systems – self microemulsifying drug delivery system (SMEDDS). Self-micro emulsifying drug delivery system (SMEDDS) is one of the exclusive approaches to increase bioavailability by improving solubility for the poorly aqueous soluble drug and to increase the oral absorption of highly lipophilic drugs. These systems have unique property to form oil in water emulsion under gentle agitation provided by digestive motility of the stomach and intestine. A greatest advantages of incorporating...
