Aspirin + Atorvastatin

Aspirin + Atorvastatin is a fixed-dose combination medicine that pairs low-dose aspirin, an antiplatelet drug, with atorvastatin, a cholesterol-lowering statin. It is used mainly to prevent cardiovascular events such as heart attacks and strokes in people who already have, or are at high risk of, cardiovascular disease. Combining the two drugs in a single pill is intended to simplify treatment and improve adherence, and such fixed-dose combinations underpin the wider polypill approach to cardiovascular prevention.

Anticoagulant

Cilostazol

Cilostazol is a phosphodiesterase 3 inhibitor with combined antiplatelet and vasodilator effects, used mainly to relieve the leg pain of intermittent claudication in peripheral artery disease. By raising levels of the signaling molecule cyclic AMP, it widens blood vessels and discourages platelets from clumping, which can lengthen the distance a person is able to walk before pain sets in. It was approved in the United States in 1999 and carries a warning against use in people with heart failure.

Anticoagulant

Clopidogrel

Clopidogrel is an oral antiplatelet medicine of the thienopyridine class that blocks the P2Y12 ADP receptor on platelets to make the blood less likely to clot [1][4]. Sold chiefly as Plavix, it is used to prevent heart attacks, strokes and other clot-related events in people with cardiovascular disease, and it is given alongside aspirin after coronary stent placement [1]. It is a prodrug that the liver must convert to its active form, and it appears on the World Health Organization's list of essential medicines [1][3].

Blend

Clopidogrel + Aspirin

Clopidogrel plus aspirin is a combination of two antiplatelet drugs, known as dual antiplatelet therapy, used to make blood clots less likely in people at high cardiovascular risk [1][2][3]. The two medicines block platelet activation by different routes, so together they inhibit clotting more completely than either alone [1][2]. The combination is a standard treatment after coronary stent placement and in acute coronary syndromes, and short courses are used soon after a minor ischaemic stroke or transient ischaemic attack; the added protection comes at the cost of a higher bleeding risk [3][4][5].

NSAID

Aspirin

Aspirin is acetylsalicylic acid, the oldest drug most people take and still the most-studied. It permanently disables cyclooxygenase by acetylating a serine in the active site [3], which is why a platelet hit once stays hit for its whole ten-day life [2]. ⚠️ It is not a selective COX-1 inhibitor: in human whole blood the preference is about fourfold [1]. Its platelet selectivity comes from where and how it acts, not from which enzyme it prefers.

Hericenone B

Hericenone B is an aromatic compound from the fruiting body of Hericium erinaceus notable not for neurotrophic activity but for a distinct cardiovascular action: it is a selective inhibitor of collagen-induced platelet aggregation. In washed rabbit and human platelets it blocked aggregation triggered by collagen while leaving other agonists such as ADP, thrombin and arachidonic acid unaffected, pointing to a novel antithrombotic mechanism. It is investigated as a lead for preventing thrombotic vascular events.
