In this work, phenoxymethylpenicillin potassium (Pen V) was selected to find a way to quickly establish a robust analysis method for the impurity profiling of penicillin. Based on the analytical quality by design (AQbD) concept and the degradation mechanism of the drug, structures of all of the DRIs were first proposed.

Pharmacology of penicillins | PPT
They work by binding to penicillin binding proteins in bacterial cell walls, inhibiting peptidoglycan synthesis and causing cell death. Penicillins are administered intravenously and excreted in urine. They can cause allergic reactions and are acid labile with a narrow spectrum of activity against bacteria that produce beta-lactamase or have ...
