Each 1 gm contains :

Ampicillin (as trihydrate) 500 mg

Ampicillin is one of the most valuable semisynthetic penicillins because whilst it retains the typical Gram – positive activity of benzyl -penicillins it possesses greatly enhanced activity against Gram – negative bacteria , so it can be described as a true bactericidal broad spectrum antibiotic.

Ampicillin is absorbed in the upper part of the intestine and excreted in a high concentrations in the bile, this means that ampicillin may be returned to the intestinal lumen through an enterohepatic circulation which makes it valuable in the treatment of enteric infections .

Ampicillin has a broad spectrum bactericidal activity against a wide range of gram - positive, gram - negative bacteria and spirochaetes, including those which cause disease in poultry.

It may be needed to combat elementary infections (E. Coli, CRD and Clostridium spp,... etc).
