SummaryDipyridamole inhibits platelet aggregation in whole blood at lower concentrations than in plasma. The blood cells responsible for increased effectiveness in blood are the erythrocytes. Using the impedance aggregometer we have carried out a series of pharmacological studies in vitro to elucidate the mechanism of action of dipyridamole in whole blood. Adenosine deaminase, an enzyme breaking down adenosine, reverses the inhibitory action of dipyridamole. Two different adenosine receptor antagonists, 5’-deoxy-5’-methylthioadenosine and theophylline, also partially neutralize the activity of dipyridamole in blood. Enprofylline, a phosphodiesterase inhibitor with almost no adenosine receptor antagonistic properties, potentiates the inhibition of platelet aggregation by dipyridamole. An inhibitory effect similar to that of dipyridamole can be obtained combining a pure adenosine uptake inhibitor (RE 102 BS) with a pure phosphodiesterase inhibitor (MX-MB 82 or enprofylline). Mixing the blood during preincubation with dipyridamole increases the degree of inhibition. Lowering the haematocrit slightly reduces the effectiveness.Although we did not carry out direct measurements of adenosine levels, the results of our pharmacological studies clearly show that dipyridamole inhibits platelet aggregation in whole blood by blocking the reuptake of adenosine formed from precursors released by red blood cells following microtrauma. Its slight phosphodiesterase inhibitory action potentiates the effects of adenosine on platelets.

SummaryWe performed a systematic review of randomized placebo-controlled pharmacological and non-pharmacological trials for the therapy and prevention of post-stroke depression that have been published between 1980 and 2011. We initially identified 2 260 records of which 28 studies were finally included into this review. A meta-analytic approach was hampered by considerable differences regarding the kinds of therapeutic regimens and the study durations. Modest effects favoring treatment of post-stroke depression could be found for pharmacological treatment as well as repetitive transcranial magnetic stimulation. For the prevention of post-stroke depression, antidepressant pharmacotherapy showed promising results. However, large-scale studies with better standardized study populations, optimized placebo control procedures in non-pharmacological studies, and replication in larger follow-up studies are still necessary to find the optimal therapeutic regimens to prevent and treat post-stroke depression.
