TIME ASPIRIN: Chronotherapy With Aspirin for Reduction of Cardiovascular Disease

2019-10-24 12:49:31 | BioPortfolio

Summary

This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.

Description

Aspirin is the cornerstone of preventive cardiovascular disease (CVD) treatment and bedtime intake of aspirin (chronotherapy) has been shown to reduce morning activity of platelets. It has been shown that platelet reactivity follows a clear circadian rhythm, with a peak of platelet reactivity during the morning (6-12 AM). Importantly, studies have shown in meta-analyses that high platelet activity is predictive of adverse cardiovascular outcomes in patients with stable CVD. Given this knowledge, it is highly likely that the morning peak of platelet reactivity contributes to the morning peak of cardiovascular events and that reduction of morning platelet activity prevents cardiovascular events during morning hours. This may be achieved by intake of aspirin at bedtime instead of on awakening. This study will be a comparative effectiveness research to determine the difference in major adverse cardiovascular events between the group with aspirin after awakening and placebo before bedtime and the group with placebo after awakening and aspirin before bedtime.

Medical and Biotech [MESH] Definitions

A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)

Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.

A drug combination of aspirin and dipyridamole that functions as a PLATELET AGGREGATION INHIBITOR, used to prevent THROMBOSIS and STROKE in TRANSIENT ISCHEMIC ATTACK patients.

The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)

A salicylate derivative and anti-inflammatory analgesic with actions and side effects similar to those of ASPIRIN.
