Methamphetamines
Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational or performance-enhancing drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder (ADHD). It has also been researched as a potential treatment for traumatic brain injury. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine. ''Methamphetamine'' properly refers to a specific chemical substance, the racemic free base, which is an equal mixture of levomethamphetamine and dextromethamphetamine in their pure amine forms, but the hydrochloride salt, commonly called crystal meth, is widely used. Methamphetamine is rarely prescribed over concerns involving its potential for recreational use as an aphrodisiac and euphoriant, among other concerns, as well as the availability of safer substitute drugs with comparable treatment efficacy such as Adderall an ...

Pholedrine
Pholedrine, also known as 4-hydroxy-''N''-methylamphetamine and sold under the brand names Paredrinol, Pulsotyl, and Veritol among others, is a sympathomimetic drug used in topical eye drops to dilate the pupil. It can be used to diagnose Horner's syndrome. In 2004, it remained marketed only in Germany. Pharmacology Pharmacodynamics Pholedrine is described as a sympathomimetic, antihypotensive, and ephedrine-like agent. Chemistry Pholedrine, also known as 4-hydroxy-''N''-methylamphetamine, is a substituted phenethylamine and amphetamine derivative. It is structurally related to methamphetamine (''N''-methylamphetamine), norpholedrine (4-hydroxyamphetamine), oxilofrine (4,β-dihydroxy-''N''-methylamphetamine), and tyramine (4-hydroxyphenethylamine). It is used pharmaceutically as the sulfate salt. The predicted log P of pholedrine ranges from 1.12 to 1.7. History Pholedrine was synthesized by 1951. Society and culture Names ''Pholedrine'' is the generic name of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, Mood disorder, mood, and physical activity, physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of neurotransmitter, excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the Receptor (biochemistry), receptors of excitatory neurotransmitters (e.g., nicotine) or by ...

CYP2D6
Cytochrome P450 2D6 (CYP2D6) is an enzyme that in humans is encoded by the ''CYP2D6'' gene. ''CYP2D6'' is primarily expressed in the liver. It is also highly expressed in areas of the central nervous system, including the substantia nigra. CYP2D6, a member of the cytochrome P450 mixed-function oxidase system, is one of the most important enzymes involved in the metabolism of xenobiotics in the body. In particular, CYP2D6 is responsible for the metabolism and elimination of approximately 25% of clinically used drugs, via the addition or removal of certain functional groups – specifically, hydroxylation, demethylation, and dealkylation. CYP2D6 also activates some prodrugs. This enzyme also metabolizes several endogenous substances, such as N,N-Dimethyltryptamine, hydroxytryptamines, neurosteroids, and both ''m''-tyramine and ''p''-tyramine which CYP2D6 metabolizes into dopamine in the brain and liver. Considerable variation exists in the efficiency and amount of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Nervous System
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilateria, bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and Coelenterata, diploblasts. It is a structure composed of nervous tissue positioned along the Anatomical_terms_of_location#Rostral,_cranial,_and_caudal, rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain, though precursor structures exist in onychophorans, gastropods and lancelets. The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals. Overview In vertebrates, the brain and spinal ...

European Monitoring Centre For Drugs And Drug Addiction
The European Union Drugs Agency (EUDA), known until 2024 as the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), is an agency of the European Union headquartered in Lisbon, Portugal, and established in 1993. In June 2022, the Council of the European Union approved a reform of the organization which lead to an extension of its mandate. The EUDA strives to be the "reference point" on drug usage for the European Union's member states, and to deliver "factual, objective, reliable and comparable information" about drug usage, drug addiction and related health complications, including hepatitis, HIV/AIDS and tuberculosis. Though the EUDA primarily serves Europe, it also works with other partners, scientists and policy-makers around the world. Mission and role The Agency was founded on the principle that independent scientific research is a "vital resource to help Europe understand the nature of its drug problems and better respond to them." Its stated missions a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kidney
In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organ (anatomy), organs that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal artery, renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the urinary bladder, bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, Acid-base homeostasis, acid-base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus (kidney), glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hy ...

Intravenous
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water per os, by mouth. It may also be used to administer pharmaceutical drug, medications or other medical therapy such as blood transfusion, blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intranasal
Nasal administration, popularly known as snorting, is a route of administration in which drugs are insufflation (medicine), insufflated through the nose. It can be a form of either topical administration or systemic administration, as the drugs thus locally delivered can go on to have either purely local or systemic effects. Nasal sprays are locally acting drugs, such as decongestants for cold and allergy treatment, whose systemic effects are usually minimal. Examples of systemically active drugs available as nasal sprays are Migraine#Management, migraine drugs, rescue medications for overdose and seizure emergencies, hormone therapy, hormone treatments, nicotine nasal spray, and nasal vaccines such as live attenuated influenza vaccine. Risks Nasal septum perforation A nasal septum perforation is a medical condition in which the nasal septum, the cartilage, bony/cartilaginous wall dividing the nostrils, nasal cavities, develops a hole or fissure.
