This article reviewed different aspects of Chitosan that’s including preparation and characterization of Chitosan with their applicability in pharmaceutical formulations. Also, the article included different derivatives of Chitosan and their use in different drug delivery system. This review emphasized that research on Chitosan based systems containing v...
We report herein the concise preparation of a range of functionalised aminoindoles via a new application of the Bartoli reaction. Scope and limitations of the methodology have been extensively studied to reveal the importance of protecting groups and substitution patterns. The use of amino substituted nitroanilines for the Bartoli reaction is to our knowledge unprecedented. Our work thus repres...
Background Colloidal silica is an inorganic substance widely used as excipient in pharmaceutical preparation. It acts as a vehicule to increase the absorption of many oral drug formulations. Many excipients have been reported to induce drug hypersensitivity such as tartrazine, aspartame, benzalkonium chloride, sodium metabisulphite, propyl gallate. However, colloidal silica has never been repor...
Pangamic acid is shown to be a mixture of variable composition. Criteria of identity and methods of analysis are described for five pharmaceutical dosage forms. Experimental results indicate that the products are not uniform in composition and that composition does not conform to label claims. No satisfactory preclinical drug application for any such preparation has so far been submitted to the...
Until about 1950, sugar coating was the first choice as coating agent for pharmaceutical preparation and much time & efforts were spent in perfecting the sugar coating techniques. Nobody ever was concerned about the problems like material cost, toxic effect due to coating or pollution etc. because the solvent used was always water. However, sugar coating technique was time consuming, affecting ...

The cancer community understands the value of blood profiling measurements in assessing and monitoring cancer. We describe an effort among academic, government, biotechnology, diagnostic, and pharmaceutical companies called the Blood Profiling Atlas in Cancer (BloodPAC) Project. BloodPAC will aggregate, make freely available, and harmonize for further analyses, raw datasets, relevant associated...
The application of reverse phase high-performance liquid chromatography to the separation and analysis of cephradine and cephalexin is demonstrated. The procedure has been applied to chemicals, pharmaceutical formulations and reaction solutions. The preparation of samples is simple and rapid. Chromatographic conditions are described for both pellicular and small particle columns. The feasibilit...
Background and purpose: Karaj River is the biggest aquatic ecosystem in Alborz province which is exposed to a variety of pharmaceutical pollutants. These pollutants have adverse effects of on surface water, biota and even humans. This research aimed to evaluate the level of contamination caused by widely used antibiotics in Karaj River, effluent, and wastewater treatment plants in 20 stations. ...
