Here, the methods include co-administering an effective amount of dipyridamole (DIP) to a human in need of such treatment in combination with an acetylsalicylic acid (ASA) and an angiotensin (ANG) II antagonist. Including:
And a suitable pharmaceutical composition comprising DIP in combination with ASA and ANGII antagonist as a combination formulation for simultaneous, separate or sequential use in the treatment of the above indications; and in combination with ASA, Use of an ANGII antagonist for the manufacture of a pharmaceutical composition for the treatment of the above indications when used in combination with DIP.
It is to be understood that the above indication prevention methods reduce the risk associated with the indication or reduce the incidence of the indication in a patient population at high risk for the indication.

Dipyridamole, {2,6-bis (diethanolamino) -4,8-dipiperidino-pyrimido [5,4-d] pyrimidine} and methods for their preparation closely related to substituted pyrimido-pyrimidines are described, for example, in the United States This is described in Japanese Patent No. 3,031,450. DIP was introduced as a coronary dilator in the early 1960s. It is also known to have platelet aggregation inhibitory activity by inhibiting adenosine uptake. Later, DIP was shown to reduce thrombus formation in a rabbit model brain arterial circulation study. These studies have led to their use as antithrombotic agents, which can quickly be applied to applications such as stroke prevention, patency maintenance of coronary artery bypass and valve replacement, and pre-coronary angioplasty procedures. Was the optimal treatment.
In addition, European Stroke Prevention Study 2 (ESPS-2; J Neurol Sci. 1996; 143: 1-13; Neurology 1998; 51: 17-19) shows that treatment with DIP alone reduces the risk of stroke. It was shown to be as effective as low-dose aspirin, and the combination therapy of DIP and aspirin was more than twice as effective as aspirin alone.
DIP appears to inhibit thrombosis through a number of mechanisms. Early studies have shown that it inhibits adenosine uptake, and adenosine was found to be a potent endogenous antithrombotic compound. DIP has also been shown to inhibit cyclic AMP phosphodiesterase, thereby increasing intracellular c-AMP.

DIP also has antioxidant properties (Free Radic. Biol. Med. 1995; 18: 239-247), which may be due to its antithrombotic activity. When oxidized, low density lipoprotein becomes recognized by the scavenger receptor on macrophages, which is postulated to be an inevitable step in the progression of atherosclerosis (Ann. Rev. Med. 1992 Year; 43: 219-25).
Inhibition of free radical formation by DIP inhibits fibrinogenesis in experimental liver fibrosis (Hepatolgy 1996; 24: 855-864) and oxygen radicals and proteinuria in experimental animals with aminonucleoside nephropathy. It was found to suppress (Eur. J. Clin. Invest. 1998; 28: 877-883; Renal Physiol. 1984; 7: 218-226). Inhibition of lipid peroxidation was also observed in human non-neoplastic lung tissue (Gen. Pharmacol. 1996; 27: 855-859).

ANGII plays a major role in pathophysiology, specifically as the most potent blood pressure raising agent in humans. Therefore, ANGII antagonists are suitable for the treatment of hypertension and congestive heart failure in mammals. Examples of ANGII antagonists are EP-A-0 502 314, EP-A-0 253 310, EP-A-0 323 841, EP-A-0 324 377, US-A-4,355,040 and US-A-4,880,804. It is described in. Specific ANGII antagonists include sultans such as candesartan, eprosartan, irbesartan, losartan, telmisartan or valsartan, as well as olmesartan and tasosartan.
In addition to its blood pressure-increasing action, ANGII is known to have a further characteristic growth promoting action, which contributes to left ventricular hypertrophy, vascular hypertrophy, atherosclerosis, renal failure and stroke. Bradykinin, on the other hand, exerts vasodilatory and tissue protective effects such as, for example, W. Wienen et al., “Antihypertensive and renoprotective effects of telmisartan after long term treatment in hypertensive diabetic (D) rats” 2nd. Int. Symposium on Angiotensin II Antagonism, February 15-18, 1999, The Queen Elizabeth II Conference Center, London, UK, Book of Abstracts, Abstract No. 50.

Losartan and irbesartan exhibit a renoprotective effect, which was found in a first clinical trial, for example, S. Andersen et al., `` Renoprotective effects of angiotensin II receptor blockade in type 1 diabetic patients with diabetic nephropathy "Kidney Int 57 (2), 601-606 (2000).
ANG II antagonists selectively inhibit the AT ₁ receptor but leave the AT ₂ receptor intact, where the AT ₂ receptor plays a role in anti-growth and tissue regeneration and is uncompetitive. (unopposed).
Completed clinical trials with ANGII antagonists appear to show blood pressure lowering and tissue protective effects similar to those with ACE inhibitors, for example, DHG Smith et al., “Once -daily telmisartan compared with enalapril in the treatment of hypertension ”, Adv. Ther 1998, 15: 229-240 and BE Karlberg et al.“ Efficacy and safety of telmisartan, a selective AT ₁ receptor antagonist, compared with enalapril in elderly patients with primary hypertension ", J Hypertens 1999, 17: 293-302.
EP-A-1 013 273 is for the treatment of diseases associated with an increase of AT ₂ receptors in increase or epithelium of AT ₁ receptors in subepithelial area, in particular, for the treatment of several pulmonary disorders, AT ₁ Disclose the use of receptor antagonists or AT ₂ receptor modulators.

Surprisingly, it has been found that administration of DIP in combination with ASA and ANGII antagonists provides an unexpected effect in the prevention or treatment of the above indications (A) to (D).
ASA acts directly on platelets to inhibit aggregation, and more specifically, it irreversibly acetylates platelet cyclooxygenase, thus inhibiting the production of thromboxanes with strong thrombogenicity. However, at high doses, aspirin crosses over endothelial cells (N. Eng. J. Med. 1984; 311: 1206-1211), where prostacyclin (a potent natural inhibitor of platelet aggregation) And which is a byproduct of the “arachidonic acid cascade” (N. Engl. J. Med. 1979; 300: 1142-1147). These observations led to the concept of low-dose antiplatelet therapy with ASA, maximizing thromboxane inhibition while minimizing loss of prostacyclin (Lancet 1981; 1: 969-971) . In the prevention method of the present invention, a combination of low dose ASA and DIP and ANGII antagonists is preferred.
