What is the initial aspirin dose in suspected ACS?

In suspected acute coronary syndrome, the priority is rapid platelet inhibition to prevent further thrombus growth and limit myocardial damage. Administer chewable aspirin in a total dose of 162–325 mg immediately to achieve fast onset. Chewing speeds absorption, giving a quicker antiplatelet effect than swallowing a pill whole. After the loading dose, continue with a low daily maintenance dose, typically 81 mg, to maintain platelet suppression. This approach is standard unless there are contraindications like active bleeding or an aspirin allergy. A smaller initial dose, like 81 mg, would delay the needed rapid effect; a 500 mg dose isn’t the recommended loading strategy in this scenario; and starting with no aspirin would withhold a proven early therapy for ACS.
