Additional information

Pharmacokinetics and dosing

According to pharmacokinetic studies conducted by the manufacturer, plasma protein binding of oral budesonide was estimated to be 85-90% in the concentration range 1-230 nmol/L and independent of patient's sex [1]. Budesonide capsules given in three different dosage regimens (3 mg, 9 mg and 15 mg) to healthy volunteers (8 men, 5 women) in an open cross-over randomized study showed no pharmacokinetic differences between men and women. A study in patients with Crohn’s Disease receiving 18 mg budesonide CIR pellets showed no sex differences in pharmacokinetics [2].


In a post hoc analysis of four RCTs (30 men, 93 women) investigating oral budesonide as treatment in collagenous colitis, multivariate analysis showed that sex and age were not among risk factors for symptom relapse [3].

Adverse effects

No studies with a clinically relevant sex analysis regarding adverse effects of oral budesonide have been found.
