Beta2-adrenergic agonists

Salmeterol is a long-acting β2 adrenergic receptor agonist (LABA) used in the treatment and prevention of asthma symptoms and control of chronic obstructive pulmonary disease (COPD) symptoms. Symptoms of bronchospasm include shortness of breath, wheezing, coughing and chest tightness. It is also used to prevent breathing difficulties during exercise (exercise-induced bronchoconstriction).

Clenbuterol is a sympathomimetic amine used by sufferers of breathing disorders as a decongestant and bronchodilator. People with chronic breathing disorders such as asthma use this as a bronchodilator to make breathing easier. It is most commonly available as the hydrochloride salt, clenbuterol hydrochloride.

Isoprenaline, also known as isoproterenol and sold under the brand name Isuprel among others, is a sympathomimetic medication which is used in the treatment of acute bradycardia (slow heart rate), heart block, and rarely for asthma, among other indications. It is used by injection into a vein, muscle, fat, or the heart, by inhalation, and in the past under the tongue or into the rectum.

Formoterol, also known as eformoterol, is a long-acting β2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h. Formoterol has a relatively rapid onset of action compared to other LABAs, and is effective within 2-3 minutes. The 2022 Global Initiative for Asthma report recommends a combination formoterol/inhaled corticosteroid inhaler as both a preve

Terbutaline, sold under the brand names Bricanyl and Marex among others, is a β2 adrenergic receptor agonist, used as a "reliever" inhaler in the management of asthma symptoms and as a tocolytic (anti-contraction medication) to delay preterm labor for up to 48 hours. This time can then be used to administer steroid injections to the mother which help fetal lung maturity and reduce complications of prematurity. It should not be used to prevent preterm labor or delay labor more than 48–72 hours. In February 2011, the Food and Drug Administration began requiring a black box warning on the drug's

Fenoterol is a β2-adrenergic receptor agonist and bronchodilator medication used in the treatment of asthma.

Ractopamine () is an animal feed additive used to promote leanness and increase food conversion efficiency in farmed animals in few countries, banned in most. Pharmacologically, it is a phenol-based TAAR1 agonist and β adrenoreceptor agonist that stimulates β1 and β2 adrenergic receptors. It is most commonly administered to animals for meat production as ractopamine hydrochloride. It is the active ingredient in products marketed in the US as Paylean for swine, Optaflexx for cattle, and Topmax for turkeys. It was developed by Elanco Animal Health, a former division of Eli Lilly and Company.

compounds that bind to and activate adrenergic beta-2 receptors

Procaterol is a β2 adrenoreceptor agonist used for the treatment of asthma in many countries, but is not approved in the United States. The drug is readily oxidized in the presence of moisture and air, and requires stabilizers for use by inhalation.

Pirbuterol (trade name Maxair) is a short-acting β2 adrenoreceptor agonist with bronchodilating action used in the treatment of asthma, available (as pirbuterol acetate) as a breath-activated metered-dose inhaler.

Arformoterol, sold under the brand name Brovana among others, is a medication used for the treatment of chronic obstructive pulmonary disease (COPD).

Ritodrine, formerly sold under the brand name Yutopar among others, is a tocolytic drug used to stop premature labor. It was withdrawn from the US market, according to the FDA Orange Book. It was available in oral tablets or as an injection and was typically used as the hydrochloride salt.

Bambuterol (INN) is a long-acting β adrenoceptor agonist (LABA) used in the treatment of asthma; it also is a prodrug of terbutaline. Commercially, the AstraZeneca pharmaceutical company produces and markets bambuterol as Bambec and Oxeol.

Levosalbutamol, also known as levalbuterol, is a β2-adrenergic receptor agonist used in the treatment of bronchospasm. Levosalbutamol is the (R)-(−)-enantiomer of its prototype drug salbutamol.

Bitolterol mesylate, formerly sold under the brand name Tornalate, is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD). Bitolterol relaxes the smooth muscles present continuously around the bronchi and bronchioles facilitating the flow of air through them.

Buphenine, also known as nylidrin and sold under the brand name Arlidin, is a β2 adrenoreceptor agonist that acts as a vasodilator.

Carbuterol (INN; carbuterol hydrochloride USAN) is a short-acting β2 adrenoreceptor agonist.

Methoxyphenamine (trade names ASMI, Euspirol, Orthoxine, Ortodrinex, Proasma), also known as '2-methoxy-N-methylamphetamine (OMMA'), is a β-adrenergic receptor agonist of the amphetamine class used as a bronchodilator.

Broxaterol is a β2 adrenoreceptor agonist. It is part of a class of drugs that affect the smooth muscle receptors in the body, often in use cases for respiratory disease that respond to this type of treatment.

Zilpaterol is a synthetic β2 adrenergic agonist. Under its brand name, Zilmax, it is used to increase the size of cattle and the efficiency of feeding them. Zilmax is produced by Intervet, a subsidiary of Merck & Co., and marketed as a "beef-improvement technology". Zilpaterol is typically fed in the last three to six weeks of cattle's lives, with a brief period (three days in the US) before death for withdrawal, which allows the drug to mostly leave the animal's tissues.
