Tuaminoheptane
Tuaminoheptane (, ; brand names Heptin, Heptadrine, Tuamine; also known as tuamine and 2-aminoheptane) is a sympathomimetic agent and vasoconstrictor which was formerly used as a nasal decongestant. It has also been used as a stimulant. Tuaminoheptane has been found to act as a reuptake inhibitor and releasing agent of norepinephrine, which may underlie its decongestant and stimulant effects. It is an alkylamine. The chemical structure of the drug differs from that of other norepinephrine releasing agents, such as the phenethylamines, which, in contrast to tuaminoheptane, have an aromatic ring in their structure. Tuaminoheptane is also a skin irritant and can cause contact dermatitis via inhibition of volume-regulated anion channels, which limits its usefulness as a decongestant. Tuaminoheptane is on the 2011 list of prohibited substances published by the World Anti-Doping Agency. See also * 1,3-Dimethylbutylamine * Heptaminol * Isometheptene * Methylhexanamine Methylhexa ...

Nasal Decongestant
A decongestant, or nasal decongestant, is a type of pharmaceutical drug that is used to relieve nasal congestion in the upper respiratory tract. The active ingredient in most decongestants is either pseudoephedrine or phenylephrine (the latter of which has disputed effectiveness). Intranasal corticosteroids can also be used as decongestants and antihistamines can be used to alleviate runny nose, nasal itch, and sneezing. Topical decongestants on topical application as dilute solution (0.05–0.1%) produce local vasoconstriction. Regular use of decongestants for long periods should be avoided because mucosal ciliary function is impaired: atrophic rhinitis and anosmia (loss of the sense of smell) can occur due to persistent vasoconstriction. Decongestants can be absorbed from the nose via an inhaler and produce systemic effects, mainly central nervous system stimulation and rise in blood pressure. These drugs should be used cautiously in hypertensives and in those receiving mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isometheptene
Isometheptene (usually as isometheptene mucate) is a sympathomimetic amine sometimes used in the treatment of migraines and tension headaches due to its vasoconstricting properties; that is, it causes constriction (narrowing) of blood vessels (arteries and veins). Along with paracetamol and dichloralphenazone, it is one of the constituents of Amidrine. Chemistry Isometheptene is a monounsaturated aliphatic secondary amine. Mechanism of action Isometheptene's vasoconstricting properties arise through activation of the sympathetic nervous system via epinephrine and norepinephrine. These compounds elicit smooth muscle activation leading to vasoconstriction by interacting with cell surface adrenergic receptors.

Heptaminol
Heptaminol is an amino alcohol which is classified as a cardiac stimulant (positive inotropic action). It also increases coronary blood flow along with mild peripheral vasoconstriction. It is sometimes used in the treatment of low blood pressure, particularly orthostatic hypotension as it is a potent positive inotrope (improving cardiac contraction). Use in doping Heptaminol is classified by the World Anti-Doping Agency as a doping substance. In 2008, the cyclist Dmitriy Fofonov tested positive for heptaminol at the Tour de France. In June 2010, the swimmer Frédérick Bousquet tested positive. In 2013, the cyclist Sylvain Georges tested positive at the Giro d'Italia. In 2014, baseball player Joel Piniero tested positive as well as St. Louis Cardinals minor league baseball player Yeison Medina. On March 22, 2019, Cycling South Africa reported that Ricardo Broxham has been sanctioned for an anti-doping rule violation of Articles 2.1 and 2.2 of the UCI Anti-Doping Rules after an ...

Sympathomimetic Agent
Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine drenaline norepinephrine oradrenaline and dopamine), which function as both neurotransmitters and hormones. Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines. Mechanisms of action The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and recep ...

Volume-regulated Anion Channel
Volume-regulated anion channels (VRACs) are crucial to the regulation of cell size by transporting chloride ions and various organic osmolytes, such as taurine or glutamate, across the plasma membrane, and that is not the only function these channels have been linked to. Some research has also suggested that VRACs may be water-permeable as well. The regulation of cell volume is necessary not only as a prevention against swelling or shrinkage caused by a change in the cell's environment, but also throughout all stages of a cell's life. The changing of a cell's volume, whether it be swelling or shrinkage, generally occurs without major changes, such as exocytic insertion or endocytic retrieval of the plasma membrane. Instead, volume regulation mostly occurs through the transport of potassium, sodium, chloride, and organic osmolytes across the membrane. The ramifications of cells not being able to regulate their volume size in relation to their environments are great as swelling leads ...

Ion Channel Blockers
A channel blocker is the biological mechanism in which a particular molecule is used to prevent the opening of ion channels in order to produce a physiological response in a cell. Channel blocking is conducted by different types of molecules, such as cations, anions, amino acids, and other chemicals. These blockers act as ion channel antagonists, preventing the response that is normally provided by the opening of the channel. Ion channels permit the selective passage of ions through cell membranes by utilizing proteins that function as pores, which allow for the passage of electrical charge in and out of the cell. These ion channels are most often gated, meaning they require a specific stimulus to cause the channel to open and close. These ion channel types regulate the flow of charged ions across the membrane and therefore mediate membrane potential of the cell. Molecules that act as channel blockers are important in the field of pharmacology, as a large portion of drug design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Octodrine
Octodrine (also known as Vaporpac or DMHA) is a stimulant drug whose pharmacology was studied in a dozen animal studies from the 1940s through the 1970s. These studies found that octodrine can increase blood pressure and cardiac output in animals. The drug was previously approved for use by the FDA as an inhalant (i.e., Vaporpac and Tickle Tackle Inhaler) and in Germany as an oral agent as part of a multicomponent medication (i.e., Ambredin and Ordinal), but is no longer available. DMHA has also been found as an adulterant in sports supplements and is sold online as a designer drug.

Methylhexanamine
Methylhexanamine (also known as methylhexamine, 1,3-dimethylamylamine, 1,3-DMAA, dimethylamylamine, and DMAA; trade names Forthane and Geranamine) is an indirect sympathomimetic drug invented and developed by Eli Lilly and Company and marketed as an inhaled nasal decongestant from 1948 until it was voluntarily withdrawn from the market in the 1970s. Since 2006 methylhexanamine has been sold extensively under many names as a stimulant or energy-boosting dietary supplement under the claim that it is similar to certain compounds found in geraniums, but its safety has been questioned as a number of adverse events and at least five deaths have been associated with methylhexanamine-containing supplements. It is banned by many sports authorities and governmental agencies. Despite multiple warning letters from the FDA, as of 2019, the stimulant remains available in sports and weight loss supplements. History In April 1944, Eli Lilly and Company introduced methylhexanamine under the bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
