It then highlights the crucial role of ectodomain shedding and microvesiculation in the propagation of "platelet storage lesion" which may affect the post-transfusion efficacy of platelet components. (biomedcentral.com)
Further studies are needed to evaluate both transfusion efficacy and healthcare cost of WPCs, and preparation of guidelines for WPC indications and contraindications is desirable. (atlasofscience.org)

The affected individual may need to avoid contact sports and medications such as aspirin, which can increase the possibility of bleeding. (wikipedia.org)

Use of drugs that induce the activity of CYP2C19 would be expected to result in increased drug levels of the active metabolite of clopidogrel and might potentiate the bleeding risk. (medlibrary.org)
Administration of eptifibatide is associated with an increase in major and minor bleeding, as classified by the criteria of the Thrombolysis in Myocardial Infarction Study group (TIMI). (globalrph.com)
The annual bleeding rate increased with increasing risk factors. (nih.gov)

NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. (nih.gov)

Use of mefenamic acid longer than 7 days increases the risk of adverse effects and is not recommended. (pdr.net)

The platelet GP IIb/IIIa complex mediates platelet-to-platelet interactions (platelet aggregation). (medscape.com)

Platelets typically circulate in the bloodstream for 7-10 days and their principal function is to survey the inner lining of blood vessels to detect and seal any breaches in the vasculature by the creation of thrombi. (biomedcentral.com)
