Hetacillin is a beta-lactam antibiotic that is part of the aminopenicillin family. It is a prodrug and it has no antibacterial activity itself, but quickly splits of acetone in the human body to form ampicillin, which is active against a variety of bacteria.
Hetacillin can be administered orally. The potassium salt, hetacillin potassium, is administered by injection, either intravenously or intramuscularly. It is sold under the trade name Hetacin for intramammary injection in veterinary use.
Hetacillin was removed from the market for human use when the discovery was made that it is actually cleaved in the gastrointestinal tract to formaldehyde and had no advantages over ampicillin.
