Antihypotensives

Antihypotensives are medications used to treat hypotension, a condition characterized by abnormally low blood pressure. Hypotension can occur due to various factors, including dehydration, heart failure, or the use of certain medications. Antihypotensives work by increasing blood pressure to a safe and effective level.

Common antihypotensives include vasopressors, which constrict blood vessels to increase blood pressure. Examples of vasopressors include norepinephrine, epinephrine, and vasopressin. These medications are often used in critical care settings, such as during surgery or in patients with severe hypotension.

Other antihypotensives include medications that stimulate the sympathetic nervous system, such as midodrine and doxazosin. These medications work by increasing the release of norepinephrine, which constricts blood vessels and increases blood pressure.

Antihypotensives should be used with caution, as they can have side effects such as increased heart rate, palpitations, and headache. It is important to use antihypotensives only under the guidance of a healthcare professional, as they can be dangerous if used improperly. In some cases, lifestyle modifications such as increasing fluid intake or wearing compression stockings may be sufficient to treat hypotension without the need for medication.
