Antihypotensive

Antihypotensive refers to a substance or treatment that counteracts hypotension, a condition characterized by abnormally low blood pressure. Hypotension can lead to symptoms such as dizziness, fainting, blurred vision, and fatigue, as it may not deliver sufficient blood flow to vital organs. Antihypotensive agents work by various mechanisms to increase blood pressure.

These agents can include medications that cause vasoconstriction, thereby narrowing blood vessels and increasing peripheral resistance. Other antihypotensive treatments may involve increasing the body's fluid volume, either through the administration of intravenous fluids or by stimulating the kidneys to retain more salt and water. In some cases, antihypotensive strategies might focus on addressing the underlying cause of the low blood pressure, such as a hormonal imbalance or an infection.

The use of antihypotensives is typically prescribed by a medical professional and depends on the specific cause and severity of the hypotension. It is important to note that the term "antihypotensive" describes a functional outcome rather than a specific class of drugs, as multiple approaches can be employed to achieve the goal of raising blood pressure.
