Defined daily dose

The DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults. The DDD is a unit of measurement and does not necessarily reflect the recommended or Prescribed Daily Dose. Therapeutic doses for individual patients and patient groups will often differ from the DDD as they will be based on individual characteristics (such as age, weight, ethnic differences, type and severity of disease) and pharmacokinetic considerations.

Active ingredients in L04AF01

Active Ingredient Description
Tofacitinib

Tofacitinib is a potent, selective inhibitor of the JAK family. In human cells, tofacitinib preferentially inhibits signalling by heterodimeric cytokine receptors that associate with JAK3 and/or JAK1. Inhibition of JAK1 and JAK3 by tofacitinib attenuates signalling of interleukins and type I and type II interferons, which will result in modulation of the immune and inflammatory response.
