Biochem./physiol. Wirkung

Wirkungsmechanismus: Ampicillin ist ein halbsynthetisches Penicillin und ein ß-Lactam-Antibiotikum, das die Zellwandsynthese von Bakterien hemmt, indem es Transpeptidasen auf der Innenoberfläche der Zellmembran der Bakterien deaktiviert.

Wirkungsweise der Resistenz: Die Verabreichung zusammen mit ß-Lactamase spaltet den ß-Lactam-Ring von Ampicillin und deaktiviert ihn.

Antimikrobielles Spektrum: Wirksam sowohl gegen grampositive (ähnlich wie Benzylpenicillin) wie auch gramnegative (ähnlich wie Tetrazykline und Chloramphenicol) Bakterien.

Vorsicht

This product has been reported stable as supplied at 25°C at 43% and 81% relative humidity for six weeks. Additional studies have shown that the stability of Ampicillin in solution is a function of pH, temperature and the identity of the buffer. It′s activity is quickly lost when stored above pH 7. Optimal storage conditions are suggested as 2-8°C, and pH 3.8-5 where its activity was retained at 90%+ for a week.

Angaben zur Herstellung

Ampicillin is reported as slightly soluble in water, practically insoluble in alcohol, chloroform, ether and fixed oils but soluble in dilute acids or bases. The solution should not be autoclaved; a stock solution should be sterilized through filtration and stored frozen, where it will be stable for months.
