Dipyridamole acts on adenosine receptors. What is adenosine?
Adenosine is an endogenous ligand, or neurotransmitter. Adenosine has medical use mainly in cardiology, it has extremely strong hypotensive effects, it strongly affects the heart, and it dilates blood vessels very strongly. However, adenosine has one major disadvantage: its biological half-life is only 30 seconds, so it has an extremely short duration of action.

If ordinary hypertension were commonly treated with Dipyridamole, or if it were the first (and last) choice drug for ordinary hypertension (and most cardiovascular diseases), then approximately 1-5% of the population would live to be perhaps 120-150 years old!!! In that case, the social insurance company would go bankrupt and would not be able to pay pensions.
With this medicine, a person can live over a hundred years, practically anyone, unless they get sick with a disease other than cardiovascular disease or have an accident.
In general, the cause of death of an old person, even if they do not suffer from any other disease, has one "certainty" that they will die of a heart attack (or other cardiovascular disease).
It is an extremely gentle and effective drug, it works on the principle of adenosine receptor agonism (and I think also on the inhibition of adenosine reuptake) and very effectively prevents embolism, thrombosis, stroke and heart attack and all other cardiovascular diseases.
This drug is intentionally mixed with aspirin by the pharmaceutical company on the commercial market. Aspirin is completely unnecessary in this drug, as Dipyridamole has very strong anti-ischemic effects on its own.

Another very beneficial effect of Dipyridamole is that it is the most effective known drug against baldness. Adenosine receptors play a strong role in baldness, hair density and hair loss. There is a study that says that adenosine doses have strong anti-baldness effects, causing hair thickening. https://en.wikipedia.org/wiki/Adenosine#Hair
Dipyridamole and psychiatric drugs
Dipyridamole also causes better penetration of psychoactive substances into the brain (through the blood-brain barrier), so the effect of psychoactive substances, psychiatric or neurological drugs is multiplied together with this drug. It would be particularly useful to increase the effectiveness of Parkinson's drugs. There is a scientific study that says that adenosine receptors play an important role in the penetration of psychoactive substances into the brain. Specifically, I think there is a scientific study that says that doses of intravenous adenosine help penetration.
