Mechanism of action

Darapladib is a selective lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor. Lp-PLA2 is an enzymatic upstream mediator of inflammatory processes. Evidence from experimental settings show that the breakdown products from oxidized low density lipoprotein C (LDL-C)such as lysophosphatidylcholine species and oxidized nonesterified fatty acids are pro-inflammatory and pro-apoptotic. These products are suspected to cause athlerosclerosis progression and plaque vulnerability, which leads to increased risk of cardiovascular problems.
