4.5    Interactions with Other Medicinal Products and Other Forms of Interaction
No formal clinical drug interaction studies with decitabine have been conducted.

There is the potential for a drug-drug interaction with other agents which are also activated by sequential phosphorylation (via intracellular phosphokinase activities) and/or metabolized by enzymes implicated in the inactivation of decitabine (e.g., cytidine deaminase). Therefore, caution should be exercised if these active substances are combined with Decitabine S.K..


Impact of co-administered medicinal products on decitabine
Cytochrome (CYP) 450-mediated metabolic interactions are not anticipated as decitabine metabolism is not mediated by this system but by oxidative deamination.

Impact of decitabine on co-administered medicinal products

Given its low in vitro plasma protein binding (<1%), decitabine is unlikely to displace co- administered medicinal products from their plasma protein binding.

Decitabine has been shown to be a weak inhibitor of P-gp mediated transport in vitro and is therefore also not expected to affect P-gp mediated transport of co-administered medicinal products (see Section 5.2).
