Nicht steroidale antiphlogistica

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [37] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [38] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [2] :10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [38]

Nicht-steroidale Antirheumatika werden, wie der Name besagt, bei Rheuma und entzündlich-rheumatischen Erkrankungen eingesetzt. Nicht-steroidale Antirheumatika sind aber auch gegen Beschwerden wie Schmerzen, Fieber und Entzündungen wirksam. Der Namensteil "nicht-steroidal" besagt, dass diese Gruppe von Wirkstoffen keine Steroide sind, also nicht das typische chemische Grundgerüst der Kortison-Verbindungen und Sexualhormone haben. Dadurch ergibt sich eine Abgrenzung zu den Glukokortikoiden , einer weiteren wichtigen Gruppe entzündungshemmender Wirkstoffe, die ebenfalls bei entzündlich-rheumatischen Erkrankungen eingesetzt werden.
