Sample Use Guides

The recommended dosage for patients with COPD is one 500 ug tablet per day, with or without food.
Route of Administration: Oral
To study the potency of roflumilast to inhibit adhesion of PMNL (polymorphonuclear leukocytes isolated from human peripheral venous blood) to TNFa-prestimulated HUVEC (human umbilical vein endothelial cells isolated from human umbilical cords) endothelial cell monolayers were stimulated with 0.3 ng/ml1 TNFa for 3 h. Medium was removed and roflumilast (10 pM–1 mM) was added followed by PMNL (50 000 cells per well) addition for 30 min. Roflumilast reduced adherence of PMNL to HUVEC with IC50 of 3.2 nM.
