Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖

|Summary of Clinical Use|
|Used to treat moderate to severe IgE-mediated (i.e. allergy triggered) persistent asthma (US) or severe asthma (EU) , in adults and children over 12 years old, inadequately controlled by inhaled corticosteroid treatment. In 2014 the US FDA approved use of this drug for the treatment of chronic idiopathic urticaria (CIU, a.k.a. chronic spontaneous urticaria) which is unresponsive to treatment with anti-histamine H1 receptor drugs.
In July 2016, the FDA expanded asthma approval to include children six to 11 years of age, as indicated previously for those 12 years-adult.
|Mechanism Of Action and Pharmacodynamic Effects|
|Binds to IgE antibodies thereby preventing their binding to, and activation of mast cells and basophils. This action leads to reduced release of mediators of the allergic response.|
