Both the rate and extent of platelet aggregation are impaired with low-dose aspirin, but neither the rate nor extent of platelet aggregation depends on the size of the dose. Platelet aggregation inhibition by a single dose of aspirin orally (greater than or equal to 81 mg) may be expected to persist for the life of the platelets affected.. . The effects of aspirin at any given time are therefore influenced by the plasma exposure and rate of platelet renewal; human platelets have a mean lifetime of 8 to 10 days and approximately 10 to 12% of platelets are replaced each day [ 2 ]. In the clinic, aspirin is used at doses from 75 mg to 1500 mg day –1..
