Exclusion Criteria

•Ischaemic stroke or haemorrhagic stroke due to non-large-vessel atherosclerosis according to TOAST criteria.
•Other anticoagulant or antiaggregant therapy except for acetyl-salicylicum treatment.

•Uncontrolled hypertension (systolic > 180 Hgmm, diastolic > 110 Hgmm).
•If QTc > 500 msec.
•Any clinically significant abnormality in clinical laboratory tests. Screening haematology and biochemistry laboratory tests must be within defined limits including full blood count within the normal range (or not clinically significantly abnormal), liver enzymes not exceed three times the upper limit of normal range, alkaline phosphatase, bilirubin not exceed twice the upper limit of normal range.

•Known hypersensitivity to acetyl-salicylicum or vinpocetine or any of the excipients of the products.
•Aspirin or other NSAID precipitate attacks of asthma, bronchospasm, acute rhinitis or urticaria.
•Active or suspected peptic or duodenal ulcer or history of recurrent peptic or duodenal ulcer or gastrointestinal bleeding or other active bleeding or bleeding disorders.
•Severe physical or mental (for example: severe dementia) concomitant disorder that might confound the conduct or result of the trial.
•Any kind of acute or chronic disorder, which can influence the level of the inflammatory markers.
•Lactating or pregnant women or women of child-bearing potential without appropriate contraceptive treatment.
•Legal incapacity and/or other circumstances rendering the patient unable to understand the nature, scope and possible consequences of the study or to cooperate on the necessary level.
•Evidence of an uncooperative attitude.
