Mechanism and effects

Dipyridamole inhibits the phosphodiesterase enzymes that normally break down cAMP (increasing cellular cAMP levels and blocking the platelet response to ADP) and/or cGMP (resulting in added benefit when given together with nitric oxide [NO] or statins).
Dipyridamole blocks the thromboxane synthase as well as the thromboxane receptor.
It inhibits the cellular reuptake of adenosine into platelets, red blood cells and endothelial cells leading to increased extracellular concentrations of adenosine.
It also inhibits the enzyme adenosine deaminase, which normally breaks down adenosine into inosine. This inhibition leads to further increased levels of extracellular adenosine.

Medical uses

  • Dipyridamole has been shown to lower pulmonary hypertension without significant drop of systemic blood pressure
  • It inhibits formation of pro-inflammatory cytokines (MCP-1, MMP-9) in vitro and results in reduction of hsCRP in patients.
  • It inhibits proliferation of smooth muscle cells in vivo and has shown to prevent AV-shunt failure in dialysis patients.
  • It increases the release of t-PA from brain microvascular endothelial cells
  • It results in an increase of 13 - HODE and decrease of 12-HETE in the subendothelial matrix (SEM) and reduced thrombogenicity of the SEM.
  • Pretreatment it reduced reperfusion injury in volunteers.
  • It has been shown to increase myocardial perfusion and left ventricular function in patients with ischemic cardiomyopathy.
  • It results in a reduction of the number of thrombin and PECAM-1 receptors on platelets in stroke patients.
  • cAMP impairs platelet aggregation and also causes arteriolar smooth muscle relaxation. Chronic therapy did not show significant drop of systemic blood pressure.
  • It inhibits the replication of mengovirus RNA.
  • It can be used for myocardial stress testing as an alternative to exercise-induced stress methods such as treadmills.

Overdose

Dipyridamole overdose can be treated with aminophylline which reverses its hemodynamic effects (vasodilation). Symptomatic treatment is recommended, possibly including a vasopressor drug. Gastric lavage should be considered. Administration of xanthine derivatives (e.g., aminophylline) may reverse the hemodynamic effects of dipyridamole overdose. Since dipyridamole is highly protein bound, dialysis is not likely to be of benefit.
