Spectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation
Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

متن کاملDetection of Phase Transitions in the Studies of Active Substanes and Solid Dosage Forms
Polymorphism is the ability of a compound in the solid state to exist in different crystalline forms. Molecules, having the same chemical composition, exhibit different spatial arrangements and/or exist in different configurations and conformations [1]. In pseudopolymorphs (solvates) molecules of solvents are incorporated into the crystal lattice. Contrary to the crystalline forms of polymorphs...
متن کاملActive Ingredients for Cosmetics
The enzymatic hydrolysis of the particular quality of raw material yield natural free amino acids and low molecular weight peptides in an ideal synergetic mixture. Tests made also directly on hair have shown the excellent properties of KELYAMIN for hair care formulations. The free amino acids are capable of penetrating the hair shaft whereas the peptides with their film-forming properties compl...
متن کاملActive Ingredients
Introduction The stratum corneum, representing the outmost layer of the skin, is a vitally important barrier of the body and protects it from various environmental stress factors. In order to maintain its elasticity, suppleness and barrier function, the skin requires optimal water content. In order to guarantee these functions skin moisture is tightly regulated by two factors, namely by the int...
