Medications against sudden death include nitroglycerin, aspirin, clopidogrel, tegretol, and salmeterol ticloson aerosol. 1. The disease with the highest rate of sudden death in clinical practice is cardiac disease, called sudden cardiac death. Patients at risk of sudden death can usually prepare their own nitroglycerin at home. Nitroglycerin can be taken sublingually when a series of precursors such as chest tightness, palpitations, etc. appear. 2. For patients with previous myocardial infarction or unstable angina, aspirin, clopidogrel, tegretol and other drugs can reduce the risk of sudden death. 3. For patients with a history of asthma, who are at risk of sudden death due to asthma, they need to prepare their own asthma medication at home, such as salmeterol ticloson aerosol. The use of medication should be under the guidance of a doctor and should not be used without authorization.
