How do transaminases interact with tigecycline in biochemical reactions?

Tigecycline does not undergo hepatic metabolism. Enzymes called transaminases do not participate in its breakdown or clearance.

How does tigecycline reach cells when transaminases are active?
Tigecycline enters bacteria mainly through passive diffusion and disruption of outer-membrane porins. Transaminases remain uninvolved in this entry step.

Why are liver enzymes measured during tigecycline treatment?
Liver-function tests, including ALT and AST, are monitored because tigecycline can cause transient enzyme elevations. These readings track drug-induced changes rather than any direct biochemical interaction.

Can other drugs that affect transaminases change tigecycline levels?
No pharmacokinetic studies show meaningful drug-drug interactions between tigecycline and transaminase-inducing or -inhibiting agents.
