4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Platelet Aggregation Inhibitors

Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system. (See all compounds classified as Platelet Aggregation Inhibitors.)


Cyclooxygenase Inhibitors

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. (See all compounds classified as Cyclooxygenase Inhibitors.)


4.2 ATC Code

B - Blood and blood forming organs

B01 - Antithrombotic agents

B01A - Antithrombotic agents

B01AC - Platelet aggregation inhibitors excl. heparin

B01AC10 - Indobufen
