  Description
5 mg Prasugrel (Elderly) Elderly participants (≥75 Years of Age) received 5 mg prasugrel for 12 days during Period 1 without intervening or terminal washout periods. They were then switched to either the 10 mg prasugrel or 75 mg clopidogrel dose in Period 2.
10 mg Prasugrel (Elderly) Elderly participants ( ≥75 year of age) on 5 mg prasugrel in Period 1 who received 10 mg prasugrel during Period 2 or 3.
75 mg Clopidogrel (Elderly) Elderly participants (≥75 year of age) on 5 mg prasugrel in Period 1 who received 75 mg clopidogrel during Period 2 or 3.
5 mg Prasugrel (Non-Elderly) Non-elderly participants (≥45 to <65 years of age) on 10 mg prasugrel in Period 1 who received 5 mg prasugrel during Period 2 or 3.
10 mg Prasugrel (Non-Elderly) Non-elderly participants (≥45 to <65 years of age) received 10 mg prasugrel for 12 days during Period 1 without intervening or terminal washout periods. They were then switched to either the 5 mg prasugrel or 75 mg clopidogrel dose in Period 2.
75 mg Clopidogrel (Non-Elderly) Non-elderly participants ( ≥45 to <65 years of age) on 10 mg prasugrel during Period 1 who received 75 mg clopidogrel during Period 2 or 3.
