Beta2-adrenergic agonist

Beta2-adrenergic agonists (pronunciation: be-ta-too ad-ren-er-jik a-go-nists), also known as beta2-adrenoceptor agonists, are a class of drugs that act on the beta2-adrenergic receptor.

Etymology

The term "Beta2-adrenergic agonist" is derived from the Greek words "βήτα" (beta), referring to the second letter of the Greek alphabet, and "ἀδρεναλίνη" (adrenaline), which is a hormone and neurotransmitter. The term "agonist" comes from the Late Latin word "agonista", meaning contender.

Function

Beta2-adrenergic agonists function by stimulating the beta2-adrenergic receptor, which is primarily found in the lungs. This stimulation leads to relaxation of smooth muscle in the airways, resulting in bronchodilation and increased airflow to the lungs.

Uses

These drugs are commonly used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). They can also be used in the management of preterm labor.

Examples

Examples of Beta2-adrenergic agonists include albuterol, salmeterol, and formoterol.

Side Effects

Potential side effects of Beta2-adrenergic agonists can include tachycardia, tremor, and hyperglycemia.
