Batalkan pi Aspirin digunakan dalam pengelolaan stroke iskemik karena fungsinya sebaga Antikoagulan Antiplatelet Antihipertensi Analgesik
Jawaban
Berikut penjelasannya:
* Aspirin adalah obat golongan salisilat yang bekerja dengan menghambat enzim siklooksigenase (COX).
* COX berperan dalam produksi tromboksan A2, yaitu zat yang menyebabkan penggumpalan darah (agregasi platelet).
* Dengan menghambat COX, aspirin mencegah pembentukan tromboksan A2, sehingga mengurangi risiko penggumpalan darah.
Stroke iskemik terjadi akibat penyumbatan pembuluh darah di otak, yang biasanya disebabkan oleh penggumpalan darah. Oleh karena itu, aspirin digunakan untuk mencegah penggumpalan darah dan mengurangi risiko stroke iskemik.
Pilihan lainnya tidak tepat karena:
* Antikoagulan bekerja dengan menghambat pembekuan darah secara keseluruhan, bukan hanya agregasi platelet.
* Antihipertensi digunakan untuk menurunkan tekanan darah.
* Analgesik digunakan untuk meredakan nyeri.
