What is "sultamicillin"

n. An oral form of the antibiotic combination ampicillin/sulbactam.

Sultamicillin is an oral form of the antibiotic combination ( codrug or mutual prodrug) ampicillin/sulbactam. It contains esterified ampicillin and sulbactam and is marketed under a number of trade names, including Saltum from Morepen Lab and Unasyn from Pfizer.

The pharmacokinetic properties of sultamicillin are improved compared to a combination of ampicillin and sulbactam. Sultamicillin increases the absorption and decreases the chances of diarrhea and dysentery. The inclusion of sulbactam extends ampicillin's spectrum of action to beta-lactamase producing strains of bacteria. Oral sulbactam with parenteral form provides a regimen of continuous sulbactam therapy throughout the treatment, resulting in better clinical results.
