Embodiment 1

[0104] Example 1-Pyridoxal-5-phosphate is used to reduce the effect of myocardial ischemic injury after coronary surgery

[0105] Methods - Study overview: 60 patients undergoing percutaneous coronary intervention (PCI) were randomly selected in 4 centers and treated with P5P or placebo in a 2:1 double-blind manner. Inclusion criteria required prior identification of a single vessel injury for non-emergency PCI and identification of ≥1 of the following clinical features that identify a high risk of procedure-related ischemic complications (Califf RM, Abdelmeguid AE, Kuntz RE, Popma JJ, Davidson CJ , Cohen EA, Kleiman NS, Mahaffey KW, Topol EJ, Pepine CJ, et al. Myonecrosis after revascularization procedures. J Am Coll Cardiol 1998; 31: 241-251; The ESPRIT Investigators. Noveldosing regimen of eptifibatide in planned coronary: stenta implantation randomised, placebo-controlled trial. Lancet 2000;356:2037-2044): Presence of acute coronary syndrome (chest pain within 48 hours of ...

Embodiment 2

[0120] Example 2-Pyridoxal-5'-phosphate combined with aspirin for reducing myocardial ischemic injury after coronary surgery

[0121] Method: Analysis Research data of Example 1. Of the 60 patients described in Example 1, 35 patients received adjuvant therapy with acetylsalicylic acid [82 mg (6 patients)] and 325 mg (29 patients) in addition to P5P therapy.

[0122] result: In patients treated with P5P and ASA, the secondary endpoint of maximum perioperative CK-MB levels was reduced from 3.41 ng / ml (placebo and ASA) to 2.09 ng / ml (P5P and ASA; Table 4).

[0123] Table 4

[0124] combination therapy

[0125] in conclusion: Combination P5P and ASA therapy was associated with a significant reduction in peak perioperative CK-MB elevation and a reduction in perioperative infarct volume.

Embodiment 3

[0126] Example 3-Pyridoxal-5'-phosphate combined with epifetide (Integrillin) is used to reduce the effect of myocardial ischemia injury after coronary artery surgery

[0127] method: The study data of Example 1 were analyzed. Of the 60 patients described in Example 1, 19 patients received adjuvant therapy with Epifetide in addition to P5P therapy.

[0128] result: The secondary endpoint of maximum perioperative CK-MB levels was reduced from 3.40 ng / ml (placebo and epifetide) to 1.36 ng / ml (P5P and substitute).

[0129] in conclusion: Combination therapy of P5P and epifetide was associated with a significant reduction in peak perioperative CK-MB elevation (Table 4), and a reduction in perioperative infarct volume.

Abstract

The present invention provides pharmaceutical compositions comprising a platelet aggregation inhibitor and a compound selected from pyridoxal-5'-phosphate, a pyridoxal-5'-phosphate related compound or a pharmaceutically acceptable salt thereof and methods for using a platelet aggregation inhibitor and a compound selected from pyridoxal-5'-phosphate, a pyridoxal-5'-phosphate related compound or a pharmaceutically acceptable salt thereof, for inhibiting platelet aggregation, for treating diseases that arise from prothrombotic and thrombotic states in which the coagulation cascade is activated and for reducing the risk of cardiovascular disease or cerebrovascular disease.

Description

technical field [0001] The present invention relates to a pharmaceutical composition and its use for treating cardiovascular diseases. In particular, the invention relates to the use of combination therapy with platelet aggregation drugs. Background technique [0002] The role of platelets in the pathophysiology of atherosclerotic disease and thrombotic events is well known. Long-term prophylactic use of antiplatelet drugs that inhibit platelet aggregation has been shown to be beneficial in preventing ischemic stroke, myocardial infarction, unstable angina, peripheral arterial disease, need for vascular bypass surgery or angioplasty, and vascular death in patients, Said patients are at increased risk of these events and include those with established atherosclerosis or a history of arterial thrombosis. [0003] Currently, many antiplatelet drugs are widely available and their combination therapy has been and continues to be studied. Most antiplatelet drugs have side effec...
