Answer

All patients presenting with ACS should receive nonenteric-coated chewable aspirin in a dose of at least 162 to 325 mg, unless there is a clear history of aspirin allergy. Patients with aspirin intolerance still should receive aspirin at presentation.

Chewable aspirin is preferred, as this promotes rapid absorption into the bloodstream to achieve faster therapeutic levels.
