Descrizione generale

Chemical structure: ß-lactam

Applicazioni

Ampicillin is a semi-synthetic derivative of penicillin that functions as a broad-spectrum antibiotic. It has been used to study antibiotic resistance and penetration limitations, the synergy between multiple antibiotics, certain bloodstream infections, and has been used to develop PCR assays to detect resistance genes in cerebrospinal fluid.

Azioni biochim/fisiol

Modalità d′azione: Si tratta di un antibiotico ß-lattamico che inibisce la sintesi della parete batterica inattivando le transpeptidasi sulla superficie interna della membrana cellulare batterica.

Modalità di resistenza: La somministrazione di ß-lattamasi scinde l′anello ß-lattamico dell′ampicillina e lo inattiva

Spettro antimicrobico: Include batteri gram positivi (simile alla benzilpenicillina) e gram negativi (simile alle tetracicline e al cloramfenicolo).

Avvertenza

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.

Nota sulla preparazione

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.

Altre note

Keep container tightly closed in a dry and well-ventilated place, hygroscopic.
