Final answer:
The alternative medication to warfarin for a stroke patient who cannot take it is clopidogrel (Plavix), particularly due to its use in dual anti-platelet therapy (DAPT) alongside aspirin, which is effective in preventing cardiovascular events and strokes.
Step-by-step explanation:
The best alternative medication to warfarin (Coumadin) for a patient with a stroke who cannot take this medication would be clopidogrel (Plavix). As per guidelines, clopidogrel plus aspirin, known as dual anti-platelet therapy (DAPT), reduces cardiovascular events more effectively than aspirin alone in patients with an acute STEMI. Clopidogrel is also often prescribed to prevent first or recurrent stroke, making it a suitable alternative in scenarios where warfarin is contraindicated.
