Description:
Mechanism of Action: Vedolizumab, a humanised IgG1 monoclonal antibody, which selectively binds to α4ß7 integrin, expressed on gut homing T lymphocyte. This blocks the adhesion of α4ß7 to mucosal addressin cell adhesion molecule-1 (MAdCAM-1) thereby inhibiting the migration of memory T-lymphocytes across the gastrointestinal parenchymal tissue thus reducing inflammation.
Pharmacokinetics:
Distribution: Crosses placenta, enters breastmilk. Volume of distribution: 5 L.
Excretion: Elimination half-life: 25 days.
|
Store between 2-8°C. Protect from light.
