KLASSE 30 /*. GRUPPE 9.CLASS 30 / *. GROUP 9.

Von den Salzen der. Acetylsalicylsäure hat allein das Lithiumsalz allgemeinere Anwendung gefunden, da es verhältnismäßig haltbar ist. Es zeigt aber, wenn auch in schwächerem Grade als das Natriumsalz, die Eigen^ schaft der Hygroskopizität und. härtet, in Tablettenform gebracht, leicht nach, so daß. aus reinem acetylsalicylsaurem Lithium gewonnene Tabletten, selbst wenn sie wohl ver- schlossen aufbewahrt sind, schon nach wenige Monate dauerndem Lagern sich in Wasser kaum noch auflösen, es sei denn, daß man sie wieder fein pulvert, was für den Verbrau^ eher natürlich unbequem ist.From the salts of the. Acetylsalicylic acid alone, the lithium salt, has more general uses found as it is relatively durable. But it shows, albeit in a weaker way Degrees than the sodium salt, the property of hygroscopicity and. hardens, in Brought into tablet form, slightly after, so that. Tablets made from pure lithium acetylsalicylic acid, even if they are are kept closed, even after a few months of storage in water hardly dissolve, unless they are finely powdered again, something for consumption is rather naturally uncomfortable.

Die üblichen Tabletterisprengmittel, wie Stärke, Tragant, Agar-Agar, haben, ganz abgesehen davon, daß sie nicht klar wasserlöslich sind, nicht die Wirkung, die Tabletten aus acetylsalicylsaurem Lithium leichter zer-The usual tablet disintegrants, such as Starch, tragacanth, agar-agar, have, quite apart from the fact that they are not clearly soluble in water are not the effect that tablets made from lithium acetylsalicylic acid disintegrate more easily.

ao fallbar zu machen, ebensowenig wasserlösliche Stoffe, wie Milchzucker, Rohrzucker, Kochsalz oder sonstige übliche indifferente Zusätze.ao to make fallable, just as little water-soluble Substances such as milk sugar, cane sugar, table salt or other common indifferent additives.

Es wurde nun gefunden, daß leicht zerfallende, nicht nachhärtende Tabletten gewon-It has now been found that easily disintegrating, non-post-hardening tablets won-

»5 nen werden können, wenn man dem Lithiumsalz einen geringen Zusatz von Alkalikarbonaten gibt. Am brauchbarsten erwies sich Na-" triumbikarbonat, von dem schön 5 Prozent genügen, um Tabletten zu erhalten, die nicht nachhärten und auch bei monatelanger Aufbewahrung in Wasser leicht löslich bleiben. Es ist bereits vorgeschlagen, Natriumbikarbonat Tabletten anderer Zusammensetzung beizumischen, damit sie im sauren Magensaft leicht zerfallen. Es war aber nicht'vorauszusehen,, daß dieser Zusatz, der seine spezifische Wirkung erst in einem sauren Medium entfaltet, die Nachhärtung von Tabletten aus acetylsalicylsaurem Lithium verhindern und sie in reinem Wasser dauernd leicht löslich erhalten würde.»5 can be achieved if you add a small amount of alkali carbonates to the lithium salt gives. Sodium bicarbonate proved to be the most useful, of which 5 percent are sufficient to obtain tablets that do not harden and even after months of storage remain easily soluble in water. It is already suggested to use sodium bicarbonate Mix tablets of a different composition so that they are absorbed in the acidic gastric juice easily disintegrate. But it was not 'to be foreseen' that this additive, its specific effect only in an acidic medium unfolded, prevent the post-hardening of tablets made from lithium acetylsalicylic acid and would keep them readily soluble in pure water at all times.
