Methoxamine

Methoxamine is an α1-adrenergic receptor agonist,[1] somewhat similar in structure to butaxamine and 2,5-DMA. It is no longer marketed.[why?] See also Sertraline Phenylephrine Synephrine Phentolamine Midodrine References .mw-parser-output .reflist{font-size:90%;margin-bottom:0.5em;list-style-type:decimal}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}...

Phentolamine

Phentolamine, sold under the brand name Regitine among others, is a reversible[1] nonselective α-adrenergic antagonist.[2] Contents 1 Mechanism 2 Uses 3 Chemistry 4 Adverse effects 5 References 6 External links Mechanism Its primary action is vasodilation due to α1 blockade.[3] Non-selective α-blockers can cause a much more pronounced reflex tachycardia than the selective α1 blockers. Like the selective α1 blocker...

Naphazoline

Naphazoline is a medicine used as a decongestant, and a vasoconstrictor added to eye drops to relieve red eye. It has a rapid action in reducing swelling when applied to mucous membrane. It is a sympathomimetic agent with marked alpha adrenergic activity that acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It was patented in 1934 and came into medical use in 1942.[1] Contents 1 Medical uses 1.1 Nasal ...

Vibegron, sold under the brand name Gemtesa, is a medication for the treatment of overactive bladder.[1][4][5] Vibegron (other names: RVT-901; MK4618; KRP114V; URO-901) is a selective beta 3 adrenergic receptor agonist. The most common side effects include headache, urinary tract infection, common cold, diarrhea, nausea, and upper respiratory tract infection.[4] It was approved for medical use in the United States in December 202...

Drug Index

Esmolol, sold under the brand name Brevibloc, is a cardioselective beta1 receptor blocker with rapid onset,[1] a very short duration of action, and no significant intrinsic sympathomimetic or membrane stabilising activity at therapeutic dosages. It is a class II antiarrhythmic.[2] Esmolol decreases the force and rate of heart contractions by blocking beta-adrenergic receptors of the sympathetic nervous system, which are found in the heart and other organs of th...

Salmeterol

Salmeterol is a long-acting β2 adrenergic receptor agonist (LABA) used in the maintenance and prevention of asthma symptoms and maintenance of chronic obstructive pulmonary disease (COPD) symptoms.[2] 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).[3] It was patented in 1983 and came into medical use in 199...

Clonidine

Clonidine, sold under the brand name Catapres among others, is an α2-adrenergic agonist[7] medication used to treat high blood pressure, attention deficit hyperactivity disorder, drug withdrawal (alcohol, opioids, or nicotine), menopausal flushing, diarrhea, spasticity and certain pain conditions.[8] It is used by mouth, by injection, or as a skin patch.[8] Onset of action is typically within an hour with the effects on blood pressure lasti...

Guanabenz

Guanabenz (pronounced GWAHN-a-benz, sold under the trade name Wytensin) is an alpha agonist of the alpha-2 adrenergic receptor that is used as an antihypertensive drug. It is used to treat high blood pressure (hypertension).[1][2] The most common side effects during guanabenz therapy are dizziness, drowsiness, dry mouth, headache and weakness. Guanabenz can make one drowsy or less alert, therefore driving or operating dangerous machinery is not recommended. ...

Salbutamol

Salbutamol, also known as albuterol and sold under the brand name Ventolin among others,[1] is a medication that opens up the medium and large airways in the lungs.[6] It is a short-acting β2 adrenergic receptor agonist which works by causing relaxation of airway smooth muscle.[6] It is used to treat asthma, including asthma attacks, exercise-induced bronchoconstriction, and chronic obstructive pulmonary disease (COPD).[6] I...

Drug Index

Alfuzosin, sold under the brand name Uroxatral among others, is a medication of the α1 blocker class. It is used to treat benign prostatic hyperplasia (BPH).[1] As an antagonist of the α1 adrenergic receptor, it works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate. Alfuzosin was patented in 1978 and approved for medical use in 1988.[2] It was approved in the US for BPH in 2003. In 2019, it was the 327th most com...

Terbutaline

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.[1] It should not be used to prevent preterm labor or delay lab...
