Ampicillin and sulbactam combination is used to treat bacterial infections in many different parts of the body. Ampicillin and sulbactam combination is an antibiotic that belongs to the group of medicines known as penicillins and beta-lactamase inhibitors. It works by killing the bacteria and preventing their growth.

Product Description:

Ampicillin with sulbactam pairs an aminopenicillin with a beta-lactamase inhibitor. Sulbactam has negligible antibacterial activity of its own; its function is to bind and inactivate beta-lactamase enzymes, restoring ampicillin's activity against organisms that would otherwise destroy it. The combination covers many Enterobacteriaceae, anaerobes including Bacteroides, and beta-lactamase-producing staphylococci, which makes it a common choice in intra-abdominal, gynaecological and skin infections.

It is supplied as powder for injection in a fixed 2:1 ratio — the 1.5 g vial delivers 1 g ampicillin with 500 mg sulbactam, the 3 g vial doubles both.

Sourcing notes. Strength is quoted inconsistently and this causes real confusion in tenders: some specifications state total content, others state the ampicillin component alone. Establish which basis applies before quoting. WHO classifies this combination under Access in the AWaRe framework, so it features prominently in essential medicines procurement and national formularies. Manufacture requires sterile powder-filling capability at the specific plant; confirm the site holds that scope rather than accepting a company-level GMP claim. Volumes in hospital and government tenders are substantial and pricing is highly competitive.
