What medications can be taken to relieve fainting?

Generally, medications such as Midodrine Hydrochloride Tablets, Atropine Sulfate Tablets, Shengmai Oral Liquid, Shenmai Injection, and Ephedrine Hydrochloride Tablets may be used under medical guidance to relieve fainting. Detailed explanations are as follows:

1. Midodrine Hydrochloride Tablets

Midodrine Hydrochloride is an α1-adrenergic receptor agonist that selectively stimulates peripheral vascular α1 receptors, causing constriction of small arteries and veins, increasing peripheral vascular resistance, and subsequently raising blood pressure. When symptoms such as dizziness and visual blurring occur due to cerebral hypoperfusion caused by postural hypotension, this medication can stabilize blood pressure fluctuations, ensure cerebral blood supply, alleviate symptoms, and prevent fainting.

2. Atropine Sulfate Tablets

Atropine Sulfate is an anticholinergic drug that blocks M-cholinergic receptors, relieves vagal nerve inhibition of the heart, increases heart rate, and improves cardiac conduction function. If fainting is caused by bradycardia-induced reduction in cardiac output and cerebral hypoperfusion, this medication can increase heart rate, enhance cardiac output, supply sufficient blood to the brain, and alleviate symptoms associated with fainting.

3. Shengmai Oral Liquid

Shengmai Oral Liquid consists of ginseng, ophiopogon root, and schisandra fruit. It functions to invigorate Qi, restore pulse, nourish Yin, and promote body fluid production. According to TCM theory, fainting is associated with deficiency of both Qi and Yin and insufficient nourishment of the heart vessels. This medication can replenish Qi and Yin, enhance cardiac function, improve systemic circulation, increase cerebral blood flow, alleviate symptoms such as dizziness, fatigue, and palpitations caused by Qi and Yin deficiency, and thereby reduce the risk of fainting.

4. Shenmai Injection

Shenmai Injection mainly contains red ginseng and ophiopogon root. It functions to invigorate Qi to prevent collapse, nourish Yin, and promote body fluid production. It is suitable for conditions such as shock and hypotension caused by Qi and Yin deficiency. It can enhance myocardial contractility, improve microcirculation, increase blood pressure and tissue perfusion capacity, supply sufficient blood to the brain and vital organs, alleviate pre-syncope caused by circulatory failure, and help restore normal body function.

5. Ephedrine Hydrochloride Tablets

Ephedrine Hydrochloride is a sympathomimetic agent that stimulates α and β receptors, constricts peripheral blood vessels, raises blood pressure, enhances myocardial contractility, and increases heart rate. For fainting caused by hypotension, this medication can elevate blood pressure, improve cardiac function, ensure cerebral blood supply, alleviate symptoms such as dizziness and confusion, and prevent fainting episodes.

Maintaining healthy lifestyle habits is important in daily life. Avoid sudden standing to reduce triggers of postural hypotension, maintain regular作息, avoid excessive fatigue, eat a balanced diet, and appropriately replenish fluids and salt to maintain normal blood pressure levels. If fainting or pre-syncope occurs frequently, seek timely medical attention to identify the underlying cause and receive standardized treatment as directed by a physician.
