Dextrofemine
Dextrofemine (), sold under the brand names Marsyl and Dysmalgine, is a uterine spasmolytic and muscle relaxant of the amphetamine family. It is the dextrorotatory enantiomer of racefemine. The drug acts as a β-adrenergic receptor agonist and sympathomimetic. It was marketed in France in 1966 but appears to no longer be marketed. Other tocolytics with similar chemical structures as phenethylamines or amphetamines include bedoradrine, buphenine, fenoterol, hexoprenaline, isoxsuprine, ritodrine, and terbutaline. See also * Phenoxyethylamine Phenoxyethylamine, also known as 2-phenoxyethylamine, is a chemical compound related to phenethylamine (2-phenylethylamine).

Substituted Amphetamines
Substituted amphetamines, or simply amphetamines, are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP). Some of amphetamine's substituted derivatives occur in nature, for example in the leaves of '' Ephedra'' and khat plants. Amphetamine was first produced at the end of the 19th century. By the 1930s, amphetamine and some of its derivative compounds found use as decongestants in the symptomat ...

Beta-adrenergic Agonist
Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways, causing widening of the airways and resulting in easier breathing. They are a class of sympathomimetic agents, each acting upon the beta adrenoceptors. In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine expresses the higher affinity. The activation of β1, β2 and β3 activates the enzyme, adenylate cyclase. This, in turn, leads to the activation of the secondary messenger cyclic adenosine monophosphate (cAMP); cAMP then activates protein kinase A (PKA) which phosphorylates target proteins, ultimately inducing smooth muscle relaxation and contraction of the cardiac tissue. Function Activation of β1 receptors induces positive inotropic, chronotropic output of the cardiac muscle, ...

Fenoterol
Fenoterol is a β2-adrenergic receptor agonist and bronchodilator medication used in the treatment of asthma. Fenoterol is produced and sold by Boehringer Ingelheim as Berotec N and in combination with ipratropium as Berodual N. It was patented in 1962 and came into medical use in 1971, but in the 1980s concerns emerged about its safety and its use being associated with an increased risk of death. Adverse effects Fenoterol is a short-acting β2 agonist that also stimulates β1 receptors. Fenoterol has more cardiovascular toxicity than isoprenaline or salbutamol. Fenoterol was widely used in New Zealand in the late 1970s and the 1980s until it was removed from the New Zealand drug tariff in 1989 because its introduction and widespread use was associated with an epidemic of asthma deaths. A series of case-control studies demonstrated that asthmatics using fenoterol were more likely to die of asthma compared with controls treated with alternative beta agonists; this risk of as ...

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. 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 label. Pregnant women should not be given injections of the drug terbutaline for the prevention of preterm labor or for long-term (beyond 48–72 hours) management of preterm labor, and should not be given oral terbutaline for any type of prevention or treatment of preterm labor "due to the potential for serious maternal heart problems and death." It was patented in 1966 and came into ...

Ritodrine
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. The drug acts as a selective β2-adrenergic receptor agonist. It was first approved for medical use in the United States in 1984. Medical uses Ritodrine is used to treat preterm labor. Contraindications Possible contraindications of ritodrine include type 2 diabetes, high blood pressure, and migraines. Side effects Most side effects of β2-adrenergic receptor agonists result from their concurrent β1-adrenergic receptor agonistic activity, and include increase in heart rate, rise in systolic blood pressure, decrease in diastolic blood pressure, chest pain secondary to myocardial infarction, and arrhythmia. β-Adrenergic receptor agonists may also cause fluid retention secondary to ...

Isoxsuprine
Isoxsuprine (used as isoxsuprine hydrochloride) is a drug used as a vasodilator in humans (under the trade name Duvadilan) and equines. Isoxsuprine is a β2 adrenoreceptor agonist that causes direct relaxation of uterine and vascular smooth muscle via β2 receptors. Use In humans Isoxsuprine is used in humans for treatment of premature labor, i.e. a tocolytic, and as a vasodilator for the treatment of cerebral vascular insufficiency, Raynaud's phenomenon, and other conditions. Isoxsuprine may increase the heart rate, cause changes in blood pressure, and irritate the GI tract. It should therefore be used with caution if combined with other drugs that affect blood pressure, such as sedatives and anesthetic drugs. In horses Isoxsuprine is most commonly used to treat hoof-related problems in the horse, most commonly for laminitis Laminitis is a disease of the feet of ungulates, found mostly in horses and cattle involving inflammation of the laminae. Clinical signs include fo ...

Hexoprenaline is a selective β2 adrenergic receptor agonist used in the treatment of asthma. Hexoprenaline is also used in some countries (such as Russia and Switzerland) as a tocolytic agent (i.e., labor suppressant), with the most common trade name being Gynipral. It is not approved by the United States Food and Drug Administration. Contraindications When used as a tocolytic, hexoprenaline is contraindicated in: * Hyperthyroidism * Cardiovascular diseases, e.g. cardiac arrhythmias, tachycardia, myocarditis, mitral valve disease and aortic stenosis * Ischemic heart disease * Hypertension * Angle-closure glaucoma * Placental abruption, vaginal bleeding and inflammatory diseases of internal genitalia (such as endometritis) * Shock * First trimester of pregnancy * Breastfeeding It should be used with caution in people with gestational diabetes. Drug-drug interactions When concomitantly administered: * Beta blockers reduce or neutralize therapeutic effects of hexoprenaline * Met ...
