In this study, we examine the relationship between the physical structure and dissolution behavior of olanzapine (OLZ) prepared via hot-melt extrusion in three polymers [polyvinylpyrrolidone (PVP) K30, polyvinylpyrrolidone-co-vinyl acetate (PVPVA) 6:4, and Soluplus® (SLP)]. In particular, we examine whether full amorphicity is necessary to achieve a favorable dissolution profile. Drug–polymer m...

Most patients with lymphoma have a reduced serum albumin concentration, often despite adequate nutrition and without evident liver disease or urinary protein loss (1-6). The etiology of this hypoalbuminemia is not clear. Possible causes include dilutional hypoalbuminemia, decreased albumin synthesis, increased albumin catabolism within the body, or excessive loss of albumin from the body throug...

Eight different pools of purified human mitochondrial and cytoplasmic isoenzymes of aspartate aminotransferase were prepared, to examine the effects of the following matrix variables: the matrix support material (bovine serum albumin and polyvinylpyrrolidone), endogenous pyridoxal concentration, and azide as an antimicrobial preservation. Storage temperatures of 25 and 37 degrees C were used as...
