ATC/DDD code J01CA for Penicillins with extended spectrum
This group comprises penicillins with enhanced activity against gram negative rods, e.g. ampicillin and similar antibiotics.
The esters, for instance pivampicillin and pivmecillinam, have a higher bioavailability and thus a lower DDD than the corresponding non-ester compounds.
The DDDs for some of the compounds, for instance carbenicillin, piperacillin, ticarcillin and sulbenicillin, are based on the dosages used for narrow indications, i.e. life threatening infections.
