Final answer:
The antiplatelet with the shortest half-life is tirofiban, which typically has a half-life of around 2 hours, allowing for a quick cessation of its effects.
Step-by-step explanation:
The antiplatelet with the shortest half-life among the options provided is tirofiban. Antiplatelet therapy is crucial for preventing blood clots in various medical conditions and during interventions such as angioplasty. Tirofiban has a short half-life, typically around 2 hours, allowing for rapid cessation of its effects if necessary. This is in contrast to antiplatelet agents like clopidogrel or ticagrelor which have longer half-lives, making them act longer in the body. It is important to choose the appropriate antiplatelet agent based on the clinical scenario and the desired duration of action.
