Stability of loratadine formulations can be affected when the product is exposed to high temperature and humidity. In this study, chemical and in vitro dissolution stability of loratadine (10 mg) tablets available in Ar...

"In this paper we study the stability of nonlinear and time-varying switched systems under restricted switching. We approach the problem by decomposing the system dynamics into a nominal-like part and a perturbationlike ...

"Suitable continuity and boundedness assumptions on the function f defining the dynamics of a time-varying nonimpulsive system with inputs are known to make the system inherit stability properties from the zero-input sys...

"This paper is concerned with the study of both, local and global, uniform asymptotic stability for switched nonlinear time-varying (NLTV) systems through the detectability of outputmaps. With this aim the notion of redu...

"This paper is concerned with the study of both, local and global, uniform asymptotic stability for switched nonlinear time-varying (NLTV) systems through the detectability of output-maps. With this aim, the notion of re...

"We provide a Lyapunov-function-based method for establishing different types of uniform input-to-state stability (ISS) for time-varying impulsive systems. The method generalizes to impulsive systems with inputs the well...

"We provide novel sufficient conditions for stability of nonlinear and time-varying impulsive systems. These conditions generalize, extend, and strengthen many existing results. Different types of input-to-state stabilit...

Matricaria recutita L. (Asteraceae), better known as chamomile, has been used due to its pharmacological properties. Laboratory-manufactured gels with chamomile extract were developed with the evaluation of the physical-...

The paper presents a study on antioxidants' effects on the stability of perfusion and organ preservation liquids, in order to obtain medicinal products characterized by higher stability and efficiency. The subject of thi...

A validated stability indicating assay method was developed for the estimation of drotaverine HCl in the presence of its degradation products. The best separation of analyte was achieved in the C8 analytical column at a...

The present research work describes comprehensive stress testing of eprosartan mesylate (EM) according to ICH guideline Q1A (R2), and development of a stability-indicating reversed phase ultra performance liquid chromato...

A stability-indicating high-performance liquid chromatographic (HPLC) and a second-order derivative spectrophotometric (UVDS) analytical methods were validated and compared for determination of simvastatin in tablets. Th...

Although octyldodecanol has been used for several decades as an ingredient for emulsions, no required Hydrophilic-Lipophilic Balance (HLB) values for this alcohol were found in the literature. The purpose of this paper...

"Very recently, it has been shown that the standard notion of stability for impulsive systems, whereby the state is ensured to approach the equilibrium only as continuous time elapses, is too weak to allow for any meanin...

"In this paper, it is shown that an algorithm for the stabilisation of switched systems introduced by the authors is robust with respect to perturbations which are unbounded in the supremum norm, but bounded in a power-l...

The objective of reducing analysis time and maintaining good efficiency, there has been substantial focus on high-speed chromatographic separations. Recently, commercially available ultra performance liquid chromatograph...

Con el objeto de seleccionar los medios más adecuados para la síntesis enzimática de péptidos, estudiamos el efecto de diferentes solventes orgánicos sobre la estabilidad de araujiaina (la preparación enzimática n...

The purpose of the present study was to prepare spherical agglomerates (SA) of piroxicam by solvent change method. Crystallization medium used for spherical agglomerates of piroxicam consisted of DMF:water and chloroform...

The objective of the present study was to stabilize doxorubicin hydrochloride in sugar-phosphate amorphous mixtures at ambient temperature by drying it with vacuum foam drying. Finished products were evaluated for foam...

El presente trabajo describe la validación de un método isocrático de HPLC destinado a la valoración cuantitativa de losartano potá- sico en tabletas y cápsulas. Fue también evaluada la estabilidad de la materia p...

"Most of the existing characterizations of the integral input-to-state stability (iISS) property are not suitable for time varying or switched (nonlinear) systems. Previous work by the authors has shown that in such case...
