Compounds possessing both a hydroxyl (-OH) and an amino group (-NH2).
Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see ADRENERGIC AGENTS). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see ADRENERGIC ALPHA-AGONISTS) are included here.
Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.
A moderately lipophilic beta blocker (ADRENERGIC BETA-ANTAGONISTS). It is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (From Martindale, The Extra Pharmocopoeia, 30th ed, p638)

A vasodilator with general properties similar to NITROGLYCERIN but with a more prolonged duration of action. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1025)
Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.
One of two major pharmacologically defined classes of adrenergic receptors. The beta adrenergic receptors play an important role in regulating CARDIAC MUSCLE contraction, SMOOTH MUSCLE relaxation, and GLYCOGENOLYSIS.

Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.

Identification of cardiac beta-adrenergic receptors by (minus) [3H]alprenolol binding. (1/127)

(Minus) [3-H] alprenolol, a potent beta-adrenergic antagonist, was used to identify binding sites in a fraction of canine cyocardium. Beta adrenergic agonists and antagonists compete for these binding sites in a manner which directly parallels their known affinity for the cardiac beta-adrenergic receptor. Thus, binding was highly stereo-specific, with the (minus) isomers of beta-adrenergic agonists or antagonists being at least two orders of magnitude more potent than were the (plus) isomers in competing for these sites. The order of potency for inhibition of binding by beta-adrenergic agonists was (minus) isoproterenol greater than (minus) epinephrine greater than (minus) norepinephrine. The dissociation constant (KD) of (minus) alprenolol for the beta-adrenergic receptors was 7-11 nM as determined independently by direct binding studies or by inhibition of isoproterenol-stimulated adenylate cyclase [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1]. The beta-adrenergic antagonist (minus) propranolol also had high affinity for the binding sites (KD equals 12 nM). The physiologically inactive catechol-containing compounds pyrocatechol and (plus or minus) dihydroxymandelic acid, as well as the metabolite (plus or minus) normetanephrine, and the alpha-adrenergic antagonist phentolamine did not compete for the binding sites at a concentration of 160 muM. Binding was rapid (t1/2 less than 30 sec) and was rapidly reversible (t1/2 less than 15 sec). The binding sites were saturable and bound 0.35 pmol of (minus) [3-H] alprenolol per mg of membrane protein. These characteristics suggest that these binding sites represent the cardiac beta-adrenergic receptors.  (+info)

Catecholamine-induced subsensitivity of adenylate cyclase associated with loss of beta-adrenergic receptor binding sites. (2/127)

Injection of frogs with beta-adrenergic catecholamines for 1-24 hr produces marked subsensitivity of the erythrocyte membrane adenylate cyclase [ATP pyrophosphate-lyase (cyclizing); EC 4.6.1.1.] to in vitro stimulation by isoproterenol. The subsensitization is specific for catecholamine stimulation, since basal and fluoride-stimulated enzyme activity are unaffected. Maximum isoproterenol-stimulated adenylate cyclase activity declines by 75% in the isoproterenol-treated animals (P less than 0.001). The concentration of isoproterenol causing one-half maximal activation of adenylate cyclase, however, is unaltered. (-)[3H]Alprenolol, a potent competitive beta-adrenergic antagonist, was used to study directly the beta-adrenergic receptor binding sites in the erythrocyte membranes from control and subsensitized animals. A highly significant (P less than 0.005) 60% fall in the number of the beta-adrenergic receptor binding sites ("specific"(-)[3H]alprenolol binding sites) in the treated animals was found. The binding affinity of the sites was not markedly altered. These data suggest that beta-adrenergic catecholamines are able to regulate catecholamine sensitivity of tissues in vivo, by regulating the properties of the beta-adrenergic receptor binding sites.  (+info)

Rapid changes in rat pineal beta-adrenergic receptor: alterations in l-(3H)alprenolol binding and adenylate cyclase. (3/127)

The properties of the beta-adrenergic receptor which regulates adenylate cyclase [ATP pyrophosphate-lyase (cyclizing)8 EC 4.6.1.1] in the pineal gland are similar to the properties of the sites which specifically bind l-[3H]alprenolol, a potent beta-adrenergic antagonist. Stimulation of the beta-adrenergic receptor results in a 30-fold increase in the activity of N-acetyltransferase (= arylamine acetyltransferase; acetyl CoA:arylamine N-acetyltransferase, EC 2.3.1.5), an enzyme involved in the synthesis of thepineal hormone melatonin. In the normal diurnal light-dark cycle there is greater physiological stimulation of the beta-adrenergic receptor in the pineal during the night than during the day. Pineals from rats kept in constant light for 24 hr possess more hormone-sensitive adenylate cyclase and specifically bind more l-[3H]alprenolol than do pineals from rats kept in the dark overnight. When rats, exposed to light for 24 hr, are treated with the beat-adrenergic agonist isoproterenol, there is a rapid loss of both hormone-sensitive adenylate cyclase activity and specific l-[3H]alprenolol binding sites. There is no change in the affinity of adenylate cyclase for isoproterenol or for its substrate, ATP. Similarly, although there are fewer binding sites, there is no change in the affinity of the remaining sites for either agonist or antagonist. Inhibition of protein synthesis with cycloheximide does not affect the loss of either adenylate cyclase activity or specific binding sites. The data suggest that stimulation of the beta-adrenergic receptor causes a rapid decrease in the number of available receptors and in hormone-sensitive adenylate cyclase activity; conversely, lack of stimulation causes an increase in these parameters. It is suggested that these changes contribute to the phenomena of super- and subsensitivity in the pineal gland by regulating the capacity of the pineal to synthesize cyclic AMP in response to beta-adrenergic stimulation.  (+info)

Involvement of beta1- and beta2- but not beta3-adrenoceptor activation in adrenergic PYY secretion from the isolated colon. (4/127)

The secretion of PYY by endocrine L cells of the terminal gut is under the control of nutrients, the autonomic nervous system and hormones. Catecholamines, and the non-specific beta-adrenergic agonist isoproterenol induce PYY secretion from rat isolated colon or ileum. Because beta3-adrenergic receptors now appear to mediate many of the effects of catecholamines in the gastrointestinal tract, we investigated the involvement of beta1-, beta2-, and beta3-adrenoceptor stimulation in PYY secretion from the isolated, vascularly perfused rat colon. Infusion of 10(-6) M isoproterenol induced a transient increase in PYY secretion (from 36+/-4 to 87+/-20 fmol/2 min; n=7, P<0.05), that was abolished by a previous infusion of the beta1- and beta2-adrenergic blocker (and partial beta3-agonist) alprenolol (10(-6) M). The beta1-adrenergic agonist dobutamine and the beta-2 agonist terbutaline also (both at 10(-5) M) significantly stimulated PYY secretion, from 29+/-1 to 79+/-12 fmol/2 min and from 19+/-1 to 73+/-13 fmol/2 min respectively (n=7, P<0.05). Neither of the beta3-adrenergic agonists tested (BRL 37 344 (10(-5), 10(-6) M) and SR 58 611A (10(-6) M)) significantly stimulated PYY secretion, thus confirming the exclusive involvement of beta1- and beta2-receptors in beta-adrenergic agonist induced hormone secretion.  (+info)

Pharmacological analysis of dopamine action on the isolated dog atrium. (5/127)

The isolated right atrium of the dog was perfused with arterial blood introduced from a carotid artery of a support dog. The selective injection of dopamine, tyramine and norepinephrine into the cannulated sinus node artery induced dose-relatedly positive chronotropic and inotropic effects. However, for an equal increase in sinus rate, dopamine caused less increase in tension development than norepinephrine. Tyramine caused least increase in contractility. Effects induced by dopamine were not blocked by treatment with tetrodotoxin which blocked those induced by nicotine. Desmethylimipramine treatment significantly suppressed dopamine-induced effects and completely blocked tyramine-induced ones but rather enhanced norepinephrine-induced ones. Alprenolol inhibited effects of dopamine, tyramine and norepinephrine. From these results, it is concluded that positive chronotropic and inotropic effects of dopamine are partly due to tyramine-like effect which causes the release of norepinephrine from sympathetic storage sites.  (+info)

Maltodextrin-based proniosomes. (6/127)

Niosomes are nonionic surfactant vesicles that have potential applications in the delivery of hydrophobic or amphiphilic drugs. Our lab developed proniosomes, a dry formulation using a sorbitol carrier coated with nonionic surfactant, which can be used to produce niosomes within minutes by the addition of hot water followed by agitation. The sorbitol carrier in the original proniosomes was soluble in the solvent used to deposit surfactant, so preparation was tedious and the dissolved sorbitol interfered with the encapsulation of one model drug. A novel method is reported here for rapid preparation of proniosomes with a wide range of surfactant loading. A slurry method has been developed to produce proniosomes using maltodextrin as the carrier. The time required to produce proniosomes by this simple method is independent of the ratio of surfactant solution to carrier material and appears to be scalable. The flexibility of the proniosome preparation method would allow for the optimization of drug encapsulation in the final formulation based on the type and amount of maltodextrin. This formulation of proniosomes is a practical and simple method of producing niosomes at the point of use for drug delivery.  (+info)

Effect of chronic beta-adrenergic receptor blockade in congestive cardiomyopathy. (7/127)

Adrenergic beta-blocking agents were given to 7 patients with advanced congestive cardiomyopathy who had tachycardia at rest (98 plus or minus 13 beats/min). The patients were on beta-adrenergic receptor blockade for 2 to 12 months (average 5-4 months). One patient was given alprenolol 50 mg twice daily and the other patients were given practolol 50 to 400 mg twice daily. Virus infection had occurred in 6 of the patients before the onset of symptoms of cardiac disease. All patients were in a steady state or were progressively deteriorating at the start of beta-adrenergic receptor blockade. Conventional treatment with digitalis and diuretics was unaltered or reduced during treatment with beta-blocking agents. An improvement was seen in their clinical condition shortly after administration of the drugs. Continued treatment resulted in an increase in physical working capacity and a reduction of heart size. Noninvasive investigations including phonocardiogram, carotid pulse curve, apex cardiogram, and echocardiogram showed improved ventricular function in all cases. The present study indicates that adrenergic beta-blocking agents can improve heart function in at lease some patients with congestive cardiomyopathy. Furthermore, it is suggested that increased catecholamine activity may be an important factor for the development of this disease, as has been shown in animal experiments.  (+info)

Identification of beta-adrenergic receptors in human lymphocytes by (-) (3H) alprenolol binding. (8/127)

Human lymphocytes are known to posessess a catecholamine-responsive adenylate cyclase which has typical beta-adrenergic specificity. To identify directly and to quantitate these beta-adenergic receptors in human lymphocytes, (-) [3H] alprenolol, a potent beta-adrenergic antagonist, was used to label binding sites in homogenates of human mononuclear leukocytes. Binding of (-) [3H] alprenolol to these sites demonstrated the kinetics, affinity, and stereospecificity expected of binding to adenylate cyclase-coupled beta-adrenergic receptors. Binding was rapid (t1/2 less than 30 s) and rapidly reversible (t1/2 less than 3 min) at 37 degrees C. Binding was a saturable process with 75 +/- 12 fmol (-) [3H] alprenolol bound/mg protein (mean +/- SEM) at saturation, corresponding to about 2,000 sites/cell. Half-maximal saturation occurred at 10 nM (-) [3H] alprenolol, which provides an estimate of the dissociation constant of (-) [3H] alprenolol for the beta-adrenergic receptor. The beta-adrenergic antagonist, (-) propranolol, potently competed for the binding sites, causing half-maximal inhibition of binding at 9 nM. beta-Adrenergic agonists also competed for the binding sites. The order of potency was (-) isoproterenol greater than (-) epinephrine greater than (-)-norepinephrine which agreed with the order of potency of these agents in stimulating leukocyte adenylate cyclase. Dissociation constants computed from binding experiments were virtually identical to those obtained from adenylate cyclase activation studies. Marked stereospecificity was observed for both binding and activation of adenylate cyclase. (-)Stereoisomers of beta-adrenergic agonists and antagonists were 9- to 300-fold more potent than their corresponding (+) stereoisomers. Structurally related compounds devoid of beta-adrenergic activity such as dopamine, dihydroxymandelic acid, normetanephrine, pyrocatechol, and phentolamine did not effectively compete for the binding sites. (-) [3H] alprenolol binding to human mononuclear leukocyte preparations was almost entirely accounted for by binding to small lymphocytes, the predominant cell type in the preparations. No binding was detectable to human erythrocytes. These results demonstrate the feasibility of using direct binding methods to study beta-adrenergic receptors in a human tissue. They also provide an experimental approach to the study of states of altered sensitivity to catecholamines at the receptor level in man.  (+info)

Alprenolol is a beta-blocker medication that is primarily used to treat hypertension (high blood pressure), angina (chest pain), and various heart rhythm disorders. It works by blocking the action of certain hormones in the body, such as adrenaline, that can cause the heart to beat faster or with increased force. This helps to reduce the workload on the heart and lower blood pressure.

Alprenolol may also be used for other purposes, such as preventing migraines or treating anxiety disorders. It is available in immediate-release and extended-release tablets, and is typically taken two to three times a day. As with any medication, Alprenolol can have side effects, including dizziness, fatigue, and gastrointestinal symptoms such as nausea or diarrhea. It is important to follow the dosage instructions provided by your healthcare provider and to report any bothersome or persistent side effects.

Amino alcohols are organic compounds containing both amine and hydroxyl (alcohol) functional groups. They have the general structure R-NH-OH, where R represents a carbon-containing group. Amino alcohols can be primary, secondary, or tertiary, depending on the number of alkyl or aryl groups attached to the nitrogen atom.

These compounds are important in many chemical and biological processes. For example, some amino alcohols serve as intermediates in the synthesis of pharmaceuticals, dyes, and polymers. In biochemistry, certain amino alcohols function as neurotransmitters or components of lipids.

Some common examples of amino alcohols include:

* Ethanolamine (monoethanolamine, MEA): a primary amino alcohol used in the production of detergents, emulsifiers, and pharmaceuticals
* Serinol: a primary amino alcohol that occurs naturally in some foods and is used as a flavoring agent
* Choline: a quaternary ammonium compound with a hydroxyl group, essential for human nutrition and found in various foods such as eggs, liver, and peanuts
* Trimethylamine (TMA): a tertiary amino alcohol that occurs naturally in some marine animals and is responsible for the "fishy" odor of their flesh.

Sympatholytics are a class of drugs that block the action of the sympathetic nervous system, which is the part of the autonomic nervous system responsible for preparing the body for the "fight or flight" response. Sympatholytics achieve this effect by binding to and blocking alpha-adrenergic receptors or beta-adrenergic receptors located in various organs throughout the body, including the heart, blood vessels, lungs, gastrointestinal tract, and urinary system.

Examples of sympatholytic drugs include:

* Alpha blockers (e.g., prazosin, doxazosin)
* Beta blockers (e.g., propranolol, metoprolol)
* Centrally acting sympatholytics (e.g., clonidine, methyldopa)

Sympatholytics are used to treat a variety of medical conditions, including hypertension, angina, heart failure, arrhythmias, and certain neurological disorders. They may also be used to manage symptoms associated with anxiety or withdrawal from alcohol or other substances.

Adrenergic beta-antagonists, also known as beta blockers, are a class of medications that block the effects of adrenaline and noradrenaline (also known as epinephrine and norepinephrine) on beta-adrenergic receptors. These receptors are found in various tissues throughout the body, including the heart, lungs, and blood vessels.

Beta blockers work by binding to these receptors and preventing the activation of certain signaling pathways that lead to increased heart rate, force of heart contractions, and relaxation of blood vessels. As a result, beta blockers can lower blood pressure, reduce heart rate, and decrease the workload on the heart.

Beta blockers are used to treat a variety of medical conditions, including hypertension (high blood pressure), angina (chest pain), heart failure, irregular heart rhythms, migraines, and certain anxiety disorders. Some common examples of beta blockers include metoprolol, atenolol, propranolol, and bisoprolol.

It is important to note that while beta blockers can have many benefits, they can also cause side effects such as fatigue, dizziness, and shortness of breath. Additionally, sudden discontinuation of beta blocker therapy can lead to rebound hypertension or worsening chest pain. Therefore, it is important to follow the dosing instructions provided by a healthcare provider carefully when taking these medications.

Pindolol is a non-selective beta blocker that is used in the treatment of hypertension (high blood pressure) and certain types of arrhythmias (irregular heart rhythms). It works by blocking the action of certain hormones such as adrenaline and noradrenaline on the heart, which helps to reduce the heart rate, contractility, and conduction velocity, leading to a decrease in blood pressure.

Pindolol is also a partial agonist at beta-2 receptors, which means that it can stimulate these receptors to some extent, reducing the likelihood of bronchospasm (a side effect seen with other non-selective beta blockers). However, pindolol may still cause bronchospasm in patients with a history of asthma or chronic obstructive pulmonary disease (COPD), so it should be used with caution in these populations.

Pindolol is available in immediate-release and extended-release formulations, and the dosage is typically individualized based on the patient's response to therapy. Common side effects of pindolol include dizziness, fatigue, and gastrointestinal symptoms such as nausea and diarrhea.

Pracitolol is not a medical condition, it's a medication. Practolol is a beta blocker drug that is primarily used to treat various cardiovascular conditions such as hypertension (high blood pressure), angina (chest pain due to reduced blood flow to the heart), and certain types of arrhythmias (irregular heart rhythms).

Beta blockers like practolol work by blocking the effects of certain hormones, such as adrenaline, on the heart and blood vessels. This helps to reduce the heart rate, lower blood pressure, and decrease the force of heart contractions, which can improve overall cardiovascular function and reduce the risk of heart-related complications.

It's important to note that practolol is not commonly used in clinical practice due to its association with a rare but serious side effect known as the "practolol syndrome." This condition can cause various symptoms such as dry eyes, skin rashes, and abnormalities of the thyroid gland. As a result, other beta blockers are generally preferred over practolol for the treatment of cardiovascular conditions.

Propranolol is a medication that belongs to a class of drugs called beta blockers. Medically, it is defined as a non-selective beta blocker, which means it blocks the effects of both epinephrine (adrenaline) and norepinephrine (noradrenaline) on the heart and other organs. These effects include reducing heart rate, contractility, and conduction velocity, leading to decreased oxygen demand by the myocardium. Propranolol is used in the management of various conditions such as hypertension, angina pectoris, arrhythmias, essential tremor, anxiety disorders, and infants with congenital heart defects. It may also be used to prevent migraines and reduce the risk of future heart attacks. As with any medication, it should be taken under the supervision of a healthcare provider due to potential side effects and contraindications.

Pentaerythritol Tetranitrate (PETN) is a powerful explosive substance, rather than a medical term. However, it can be used in a medical context as an active ingredient in certain prescription medications.

Medically, Pentaerythritol Tetranitrate is classified as a nitrate vasodilator. It works by relaxing and widening blood vessels, which allows for increased oxygen delivery and improved blood flow, particularly to the heart muscle. This can help reduce the workload on the heart and alleviate symptoms of angina (chest pain) caused by coronary artery disease.

It is available in various forms, such as extended-release tablets or sublingual (under-the-tongue) tablets, under brand names like Nitrolingual®, Nitrostat®, and Pentaerythritol Tetranitrate ER®.

Please consult a healthcare professional for more information about this medication and its uses.

Adrenergic receptors are a type of G protein-coupled receptor that bind and respond to catecholamines, which include the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline). These receptors play a crucial role in the body's "fight or flight" response and are involved in regulating various physiological functions such as heart rate, blood pressure, respiration, and metabolism.

There are nine different subtypes of adrenergic receptors, which are classified into two main groups based on their pharmacological properties: alpha (α) and beta (β) receptors. Alpha receptors are further divided into two subgroups, α1 and α2, while beta receptors are divided into three subgroups, β1, β2, and β3. Each subtype has a unique distribution in the body and mediates distinct physiological responses.

Activation of adrenergic receptors occurs when catecholamines bind to their specific binding sites on the receptor protein. This binding triggers a cascade of intracellular signaling events that ultimately lead to changes in cell function. Different subtypes of adrenergic receptors activate different G proteins and downstream signaling pathways, resulting in diverse physiological responses.

In summary, adrenergic receptors are a class of G protein-coupled receptors that bind catecholamines and mediate various physiological functions. Understanding the function and regulation of these receptors is essential for developing therapeutic strategies to treat a range of medical conditions, including hypertension, heart failure, asthma, and anxiety disorders.

Adrenergic receptors are a type of G protein-coupled receptor that binds and responds to catecholamines, such as epinephrine (adrenaline) and norepinephrine (noradrenaline). Beta adrenergic receptors (β-adrenergic receptors) are a subtype of adrenergic receptors that include three distinct subclasses: β1, β2, and β3. These receptors are widely distributed throughout the body and play important roles in various physiological functions, including cardiovascular regulation, bronchodilation, lipolysis, and glucose metabolism.

β1-adrenergic receptors are primarily located in the heart and regulate cardiac contractility, chronotropy (heart rate), and relaxation. β2-adrenergic receptors are found in various tissues, including the lungs, vascular smooth muscle, liver, and skeletal muscle. They mediate bronchodilation, vasodilation, glycogenolysis, and lipolysis. β3-adrenergic receptors are mainly expressed in adipose tissue, where they stimulate lipolysis and thermogenesis.

Agonists of β-adrenergic receptors include catecholamines like epinephrine and norepinephrine, as well as synthetic drugs such as dobutamine (a β1-selective agonist) and albuterol (a non-selective β2-agonist). Antagonists of β-adrenergic receptors are commonly used in the treatment of various conditions, including hypertension, angina pectoris, heart failure, and asthma. Examples of β-blockers include metoprolol (a β1-selective antagonist) and carvedilol (a non-selective β-blocker with additional α1-adrenergic receptor blocking activity).

Isoproterenol is a medication that belongs to a class of drugs called beta-adrenergic agonists. Medically, it is defined as a synthetic catecholamine with both alpha and beta adrenergic receptor stimulating properties. It is primarily used as a bronchodilator to treat conditions such as asthma and chronic obstructive pulmonary disease (COPD) by relaxing the smooth muscles in the airways, thereby improving breathing.

Isoproterenol can also be used in the treatment of bradycardia (abnormally slow heart rate), cardiac arrest, and heart blocks by increasing the heart rate and contractility. However, due to its non-selective beta-agonist activity, it may cause various side effects such as tremors, palpitations, and increased blood pressure. Its use is now limited due to the availability of more selective and safer medications.

Oxprenolol is a non-selective beta blocker and partial agonist of beta-adrenergic receptors. It works by blocking the effects of certain chemicals on the heart and blood vessels, which can help to reduce heart rate, blood pressure, and strain on the heart. Oxprenolol is used to treat angina (chest pain), high blood pressure, irregular heartbeats, and tremors. It may also be used for other purposes not listed here.

It's important to note that oxprenolol should only be taken under the supervision of a medical professional, as it can have significant interactions with other medications and medical conditions. Additionally, sudden discontinuation of oxprenolol should be avoided, as it can lead to rebound effects such as increased heart rate and blood pressure.

Adrenergic beta-agonists are a class of medications that bind to and activate beta-adrenergic receptors, which are found in various tissues throughout the body. These receptors are part of the sympathetic nervous system and mediate the effects of the neurotransmitter norepinephrine (also called noradrenaline) and the hormone epinephrine (also called adrenaline).

When beta-agonists bind to these receptors, they stimulate a range of physiological responses, including relaxation of smooth muscle in the airways, increased heart rate and contractility, and increased metabolic rate. As a result, adrenergic beta-agonists are often used to treat conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, as they can help to dilate the airways and improve breathing.

There are several different types of beta-agonists, including short-acting and long-acting formulations. Short-acting beta-agonists (SABAs) are typically used for quick relief of symptoms, while long-acting beta-agonists (LABAs) are used for more sustained symptom control. Examples of adrenergic beta-agonists include albuterol (also known as salbutamol), terbutaline, formoterol, and salmeterol.

It's worth noting that while adrenergic beta-agonists can be very effective in treating respiratory conditions, they can also have side effects, particularly if used in high doses or for prolonged periods of time. These may include tremors, anxiety, palpitations, and increased blood pressure. As with any medication, it's important to use adrenergic beta-agonists only as directed by a healthcare professional.

Propanolamines are a class of pharmaceutical compounds that contain a propan-2-olamine functional group, which is a secondary amine formed by the replacement of one hydrogen atom in an ammonia molecule with a propan-2-ol group. They are commonly used as decongestants and bronchodilators in medical treatments.

Examples of propanolamines include:

* Phenylephrine: a decongestant used to relieve nasal congestion.
* Pseudoephedrine: a decongestant and stimulant used to treat nasal congestion and sinus pressure.
* Ephedrine: a bronchodilator, decongestant, and stimulant used to treat asthma, nasal congestion, and low blood pressure.

It is important to note that propanolamines can have side effects such as increased heart rate, elevated blood pressure, and insomnia, so they should be used with caution and under the supervision of a healthcare professional.

Dihydroalprenolol is a non-selective beta blocker drug, which means it blocks both beta-1 and beta-2 receptors. Beta blockers are medications that reduce the effects of epinephrine (adrenaline) in the body, thereby slowing down the heart rate, reducing blood pressure, and decreasing the force of heart contractions.

Dihydroalprenolol is primarily used to treat hypertension (high blood pressure), angina pectoris (chest pain due to reduced blood flow to the heart muscle), and certain types of arrhythmias (irregular heart rhythms). It may also be used for other indications, such as preventing migraines or reducing anxiety before surgery.

Like other beta blockers, dihydroalprenolol works by blocking the action of epinephrine on beta receptors in the heart and blood vessels, leading to decreased heart rate, reduced force of heart contractions, and dilated blood vessels. This results in lower blood pressure and improved blood flow to the heart muscle.

It is important to note that dihydroalprenolol may have side effects, such as fatigue, dizziness, and gastrointestinal symptoms, and it should be used under the guidance of a healthcare professional. Additionally, sudden discontinuation of beta blockers can lead to rebound hypertension or other adverse effects, so it is essential to taper off the medication gradually under medical supervision.

Nadolol is a non-selective beta blocker medication that works by blocking the action of certain natural substances such as adrenaline (epinephrine) on the heart and blood vessels. This results in a decrease in heart rate, heart contractions strength, and lowering of blood pressure. Nadolol is used to treat high blood pressure, angina (chest pain), irregular heartbeats, and to prevent migraines. It may also be used for other conditions as determined by your doctor.

Nadolol is available in oral tablet form and is typically taken once a day. The dosage will depend on the individual's medical condition, response to treatment, and any other medications they may be taking. Common side effects of Nadolol include dizziness, lightheadedness, tiredness, and weakness. Serious side effects are rare but can occur, such as slow or irregular heartbeat, shortness of breath, swelling of the hands or feet, mental/mood changes, and unusual weight gain.

It is important to follow your doctor's instructions carefully when taking Nadolol, and to inform them of any other medications you are taking, as well as any medical conditions you may have, such as diabetes, asthma, or liver disease. Additionally, it is recommended to avoid sudden discontinuation of the medication without consulting with your healthcare provider, as this can lead to withdrawal symptoms such as increased heart rate and blood pressure.

Epinephrine, also known as adrenaline, is a hormone and a neurotransmitter that is produced in the body. It is released by the adrenal glands in response to stress or excitement, and it prepares the body for the "fight or flight" response. Epinephrine works by binding to specific receptors in the body, which causes a variety of physiological effects, including increased heart rate and blood pressure, improved muscle strength and alertness, and narrowing of the blood vessels in the skin and intestines. It is also used as a medication to treat various medical conditions, such as anaphylaxis (a severe allergic reaction), cardiac arrest, and low blood pressure.

Pentobarbital is a barbiturate medication that is primarily used for its sedative and hypnotic effects in the treatment of insomnia, seizure disorders, and occasionally to treat severe agitation or delirium. It works by decreasing the activity of nerves in the brain, which produces a calming effect.

In addition to its medical uses, pentobarbital has been used for non-therapeutic purposes such as euthanasia and capital punishment due to its ability to cause respiratory depression and death when given in high doses. It is important to note that the use of pentobarbital for these purposes is highly regulated and restricted to licensed medical professionals in specific circumstances.

Like all barbiturates, pentobarbital has a high potential for abuse and addiction, and its use should be closely monitored by a healthcare provider. It can also cause serious side effects such as respiratory depression, decreased heart rate, and low blood pressure, especially when used in large doses or combined with other central nervous system depressants.

Adrenergic beta-2 receptor antagonists, also known as beta-2 adrenergic blockers or beta-2 antagonists, are a class of medications that block the action of epinephrine (adrenaline) and other catecholamines at beta-2 adrenergic receptors. These receptors are found in various tissues throughout the body, including the lungs, blood vessels, and skeletal muscles.

Beta-2 adrenergic receptor antagonists are primarily used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). They work by relaxing the smooth muscle in the airways, which helps to reduce bronchoconstriction and improve breathing.

Some examples of beta-2 adrenergic receptor antagonists include:

* Butoxamine
* ICI 118,551
* Salbutamol (also a partial agonist)
* Terbutaline (also a partial agonist)

It's important to note that while these medications are called "antagonists," some of them can also act as partial agonists at beta-2 receptors, meaning they can both block the action of catecholamines and stimulate the receptor to some degree. This property can make them useful in certain clinical situations, such as during an asthma attack or preterm labor.

"Anura" is a term used in the field of zoology, particularly in the study of amphibians. It refers to a order that includes frogs and toads. The name "Anura" comes from the Greek language, with "an-" meaning "without," and "oura" meaning "tail." This is a reference to the fact that members of this order lack tails in their adult form.

The Anura order is characterized by several distinct features:

1. They have short, powerful legs that are well adapted for jumping or leaping.
2. Their forelimbs are smaller and less specialized than their hind limbs.
3. Most anurans have a moist, glandular skin, which helps them to breathe and absorb water.
4. Anura includes both aquatic and terrestrial species, with varying degrees of adaptations for each environment.
5. They lay their eggs in water, and their larvae (tadpoles) are aquatic, undergoing a process called metamorphosis to transform into the adult form.

Anura contains approximately 7,000 known species, making it one of the largest orders of vertebrates. They have a cosmopolitan distribution and can be found on every continent except Antarctica. Anurans play essential roles in many ecosystems as both predators and prey, contributing to the regulation of insect populations and serving as indicators of environmental health.

Adrenergic receptors are a type of G protein-coupled receptor that bind and respond to catecholamines, such as epinephrine (adrenaline) and norepinephrine (noradrenaline). Beta-2 adrenergic receptors (β2-ARs) are a subtype of adrenergic receptors that are widely distributed throughout the body, particularly in the lungs, heart, blood vessels, gastrointestinal tract, and skeletal muscle.

When β2-ARs are activated by catecholamines, they trigger a range of physiological responses, including relaxation of smooth muscle, increased heart rate and contractility, bronchodilation, and inhibition of insulin secretion. These effects are mediated through the activation of intracellular signaling pathways involving G proteins and second messengers such as cyclic AMP (cAMP).

β2-ARs have been a major focus of drug development for various medical conditions, including asthma, chronic obstructive pulmonary disease (COPD), heart failure, hypertension, and anxiety disorders. Agonists of β2-ARs, such as albuterol and salmeterol, are commonly used to treat asthma and COPD by relaxing bronchial smooth muscle and reducing airway obstruction. Antagonists of β2-ARs, such as propranolol, are used to treat hypertension, angina, and heart failure by blocking the effects of catecholamines on the heart and blood vessels.

Adenylate cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP). It plays a crucial role in various cellular processes, including signal transduction and metabolism. Adenylate cyclase is activated by hormones and neurotransmitters that bind to G-protein-coupled receptors on the cell membrane, leading to the production of cAMP, which then acts as a second messenger to regulate various intracellular responses. There are several isoforms of adenylate cyclase, each with distinct regulatory properties and subcellular localization.

Respiratory physiological phenomena refer to the various mechanical, chemical, and biological processes and functions that occur in the respiratory system during breathing and gas exchange. These phenomena include:

1. Ventilation: The movement of air into and out of the lungs, which is achieved through the contraction and relaxation of the diaphragm and intercostal muscles.
2. Gas Exchange: The diffusion of oxygen (O2) from the alveoli into the bloodstream and carbon dioxide (CO2) from the bloodstream into the alveoli.
3. Respiratory Mechanics: The physical properties and forces that affect the movement of air in and out of the lungs, such as lung compliance, airway resistance, and chest wall elasticity.
4. Control of Breathing: The regulation of ventilation by the central nervous system through the integration of sensory information from chemoreceptors and mechanoreceptors in the respiratory system.
5. Acid-Base Balance: The maintenance of a stable pH level in the blood through the regulation of CO2 elimination and bicarbonate balance by the respiratory and renal systems.
6. Oxygen Transport: The binding of O2 to hemoglobin in the red blood cells and its delivery to the tissues for metabolic processes.
7. Defense Mechanisms: The various protective mechanisms that prevent the entry and colonization of pathogens and foreign particles into the respiratory system, such as mucociliary clearance, cough reflex, and immune responses.

Intravenous anesthesia, also known as IV anesthesia, is a type of anesthesia that involves the administration of one or more drugs into a patient's vein to achieve a state of unconsciousness and analgesia (pain relief) during medical procedures. The drugs used in intravenous anesthesia can include sedatives, hypnotics, analgesics, and muscle relaxants, which are carefully selected and dosed based on the patient's medical history, physical status, and the type and duration of the procedure.

The administration of IV anesthesia is typically performed by a trained anesthesiologist or nurse anesthetist, who monitors the patient's vital signs and adjusts the dosage of the drugs as needed to ensure the patient's safety and comfort throughout the procedure. The onset of action for IV anesthesia is relatively rapid, usually within minutes, and the depth and duration of anesthesia can be easily titrated to meet the needs of the individual patient.

Compared to general anesthesia, which involves the administration of inhaled gases or vapors to achieve a state of unconsciousness, intravenous anesthesia is associated with fewer adverse effects on respiratory and cardiovascular function, and may be preferred for certain types of procedures or patients. However, like all forms of anesthesia, IV anesthesia carries risks and potential complications, including allergic reactions, infection, bleeding, and respiratory depression, and requires careful monitoring and management by trained medical professionals.

Catecholamines are a group of hormones and neurotransmitters that are derived from the amino acid tyrosine. The most well-known catecholamines are dopamine, norepinephrine (also known as noradrenaline), and epinephrine (also known as adrenaline). These hormones are produced by the adrenal glands and are released into the bloodstream in response to stress. They play important roles in the "fight or flight" response, increasing heart rate, blood pressure, and alertness. In addition to their role as hormones, catecholamines also function as neurotransmitters, transmitting signals in the nervous system. Disorders of catecholamine regulation can lead to a variety of medical conditions, including hypertension, mood disorders, and neurological disorders.

Norepinephrine, also known as noradrenaline, is a neurotransmitter and a hormone that is primarily produced in the adrenal glands and is released into the bloodstream in response to stress or physical activity. It plays a crucial role in the "fight-or-flight" response by preparing the body for action through increasing heart rate, blood pressure, respiratory rate, and glucose availability.

As a neurotransmitter, norepinephrine is involved in regulating various functions of the nervous system, including attention, perception, motivation, and arousal. It also plays a role in modulating pain perception and responding to stressful or emotional situations.

In medical settings, norepinephrine is used as a vasopressor medication to treat hypotension (low blood pressure) that can occur during septic shock, anesthesia, or other critical illnesses. It works by constricting blood vessels and increasing heart rate, which helps to improve blood pressure and perfusion of vital organs.

During the extensive two-year review process for the 2021 version of the Code, WADA received considerable stakeholder feedback related to drugs of abuse where it was felt that the use of some substances included in the Prohibited List was often unrelated to sport practice. Accordingly, Article 4.2.3 was added to the 2021 Code defining Substances of Abuse as those "Prohibited Substances which are specifically identified as Substances of Abuse on the Prohibited List because they are frequently abused in society outside of the context of sport.". In this context, cocaine, diamorphine (heroin), methylenedioxymethamphetamine (MDMA/"ecstasy") and tetrahydrocannabinol (THC) are designated as Substances of Abuse. These 4 substances are prohibited in competition but sometimes their use out-of-competition can be detected in-competition and lead to an Adverse Analytical Finding. If the athlete can demonstrate that the use of any of these four substances was out-of -competition and unrelated to sport ...
