INTRODUCTION In comparison with the extremely frequent use of corticosteroids in different diseases, immediate allergic reactions remain uncommon. In addition to the steroid molecule, the causative agent of these reactions can be an excipient. MATERIAL AND METHODS We report seven cases of immediate reactions induced by different preparations of corticosteroids. Skin tests with the suspected s...

Nifedipine is an antihypertensive BCS class II drug which has poor bioavailability when given orally. The objective of the present study was to increase the bioavailability of nifedipine, by formulation and evaluation of a buccoadhesive liquisolid system using magnesium aluminium silicate (Neusilin) as both carrier and coating material and dissolution media were selected based on the solubility...

This paper studies the effects of glycerol plasticizers and/or alginate, pectin, and carboxymethylcellulose polysaccharides on mechanical physical properties porphyran-based films to evaluate films’ ability be used as food packaging. Films were characterized in terms their composition, microstructural morphological features, thermal properties, water interaction, performance. All are homogeneou...

The procedure usually employed for specifying a set of hydrocyclones used in Newtonian fluidsolid separation processes can be extended to the case of non-Newtonian fluids. The apparent viscosity, μapp, is the link between the two cases, and can be evaluated from the knowledge of the shear stress function, S, and the characteristic rate of shear, λ*. In order to verify the validity of this, expe...
