Sultamicillin，一种口服 Ampicillin/Sulbactan 的双前体药物。Sulbactam 是一种半合成的 β-内酰胺酶抑制剂，它与 Ampicillin 结合，将后者的抗菌活性扩展到包括一些产生 β-内酰胺酶的细菌菌株，否则将是耐药的。 Sultamicillin is an orally active double prodrug of Ampicillin/Sulbactan. Sulbactam is a semisynthetic beta-lactamase inhibitor which, in combination with Ampicillin, extends the antibacterial activity of the latter to include some beta-lactamase-producing strains of bacteria that would otherwise be resistant。
