That DXM feels so distinct beyond that is just a bonus.
|
|
DXM and ketamine are part of a drug family called glutamate blockers.
|
|
Robotripping is basically an intentional overdose of DXM, the active ingredient in cough syrup.
|
|
DXM, on the other hand, is a hallucinogen that can trigger psychosis in high doses.
|
|
But when it comes to DXM, he encourages caution, adding that even he is skeptical.
|
|
Axome is trying a two-in-one pill of DXM and the common antidepressant bupropion.
|
|
Adding quinidine to DXM keeps it in the body for a longer period of time.
|
|
Once again like Armored Core or MechWarrior, DXM is a game split between two phases of play.
|
|
In theory, antitussive drugs (like Dextromethorphan, often referred to as DM or DXM) block the body's cough reflex.
|
|
DXM molecules looked like codeine and stopped the cough well enough, but otherwise couldn't be more different, Kaplin says.
|
|
But DXM does it differently, in a way that brings it closer to action RPGs, or even Monster Hunter.
|
|
Kaplin is one of the first people attempting to find out how DXM works in practice to help treat depression.
|
|
Soon, his team at Johns Hopkins hopes to explore how long and at what dose DXM might have antidepressant effects.
|
|
More from Tonic: The US government first chanced upon DXM about 50 years ago while researching a non-addictive replacement for codeine in cough syrups.
|
|
From that premise, DXM weaves a conspiratorial yarn about powerful AI, flailing governments, opportunistic corporations, and the people caught in the middle of all three.
|
|
Cough suppressant or not, DXM is particularly attractive as a potential antidepressant because it's a glutamate blocker (like ketamine) and a serotonin booster (like normal antidepressants).
|
|
Avanir is repurposing an existing drug called Nuedexta, which is a mix of DXM and quinidine, a chemical used to block the liver's ability to break down drugs.
|
|
But that didn't stop the government from allowing its use: The drug remains over-the-counter, even though studies have suggested DXM might not help with cough at all.
|
|
One reason the researchers think DXM has potential for treating depression is that it works a little like ketamine, perhaps the most successful street drug thus far repurposed for treating depression.
|
|
Over the past three years, clinicians at several universities have begun experimenting with hallucination-inducing doses of the drug dextromethorphan (DXM), a common ingredient in several over-the-counter cough medicine brands.
|
|
DXM isn't the only mech game with loot—one of my favorite parts of Battletech (my 2018 Game of the Year) was seeing the list of salvageable loot at the end of a mission.
|
|
For reasons unknown, slowing down glutamate activity with DXM or ketamine appears to ease symptoms of depression, says Adam Kaplin, an assistant professor of psychiatry and behavioral sciences and researcher who specializes in experimental antidepressants at Johns Hopkins.
|
|
They found one with dextromethorphan, or DXM, used in over-the counter cough medications and considered addictive when abused; and four with a synthetic cannabinoid, sometimes called Spice, that can cause anxiety, psychosis, tachycardia and death, according to a study last year in Forensic Science International.
|
|
While many games in the mech space—not only Armored Core, but also franchises like MechWarrior and Titanfall—lean towards stylized, milspec "realism," DXM wears its anime influence on its sleeve (and not only because Macross co-creator Shoji Kawamori helped design DXM's mechs, nor because of the inclusion of Gundam voice actors Toru Furuya (Amuro) and Shuichi Ikeda (Char) in the game's Japanese voice cast, though those help).
|
|
Similarly to DXM and DXO, dimemorfan has only relatively low affinity for the σ2 receptor (Ki = 4,421 nM).
|
|
The first band that Kaplan played for was DXM, an underground sampler-driven group in Tel Aviv. He chose playing for DXM instead of taking clarinet lessons. He stayed in Israel until 1991, which is when he immigrated to the United States. After getting a degree from Mannes College in 1996, Kaplan formed a group with Tom Abbs and Geoff Mann called "Trio Plus".
|
|
Rarer side effects included panic attacks, impaired learning, tremor, jaundice, urticaria (hives), and myalgia. DXM has also been "known to increase the frequency of complex partial seizures in epileptics by 25% compared to placebo." Frequent and long-term usage at high doses could possibly lead to toxic psychosis and other permanent psychological problems. Medical DXM use has not been shown to cause the above issues.
|
|
Drugs of this class are unlikely candidates for pharmacological prevention of addiction because these drugs themselves are used recreationally. Examples of NMDAR antagonists are ketamine, dextromethorphan (DXM), phencyclidine (PCP).
|
|
Nitrous oxide, a common anesthetic for humans (especially in dentistry), has also been shown to cause vacuolization in rats' brains, but caused no irreversible lesions. Dextromethorphan, a common antitussive often found in cough medicines, has been shown to cause vacuolization in rats' brains when administered at doses of 75 mg/kg. However, oral administration of dextromethorphan hydrobromide (DXM HBr) to female rats in single doses as high as 120 mg/kg did not result in detectable neurotoxic changes at 4–6 hours or 24–26 hours post-dose (female rats are more sensitive to NMDA antagonist neurotoxicity). The same researchers also found no evidence of neurotoxic changes in retrosplenial or cingulate cortices of male rats orally administered up to 400 mg/(kg day) DXM HBr or female rats orally administered 120 mg/(kg day) DXM HBr, both for 30 days.

DXO is an active metabolite of the pharmaceutical drug dextromethorphan (DXM), which, analogously to DXO, is an enantiomer of the racemic mixture racemethorphan along with levomethorphan, the latter of which has similar properties to those of levorphanol.

Some NMDA receptor antagonists, such as ketamine, dextromethorphan (DXM), phencyclidine (PCP), methoxetamine (MXE), and nitrous oxide (N2O), are recreational drugs used for their dissociative, hallucinogenic, and euphoriant properties. When used recreationally, they are classified as dissociative drugs.
|
|
Cough medicine containing dextromethorphan in gel cap form Dextromethorphan, or DXM, a common active ingredient found in many over-the-counter cough suppressant cold medicines, is used as a recreational drug and entheogen for its dissociative effects. It has almost no psychoactive effects at medically recommended doses. However, dextromethorphan has powerful dissociative properties when administered in doses well above those considered therapeutic for cough suppression. Recreational use of DXM is sometimes referred to in slang form as "robo-tripping", whose prefix derives from the Robitussin brand name, or "Triple Cs", which derives from the Coricidin brand.

Anabolic steroids, including testosterone and human chorionic gonadotropin are Schedule 3 on the California Uniform Controlled Substances Act. On August 31, 2011, California Legislature passed SB 514, which banned the sale of dextromethorphan (DXM), the active ingredient in most over-the-counter cough medicines, to minors.

Dimemorfan (INN) (or dimemorphan) (brand names Astomin, Dastosirr, Tusben), or dimemorfan phosphate (JAN), also known as 3,17-dimethylmorphinan, is an antitussive (cough suppressant) of the morphinan family that is widely used in Japan and is also marketed in Spain and Italy. It was developed by Yamanouchi Pharmaceutical (now Astellas Pharma) and introduced in Japan in 1975. Dimemorfan is an analogue of dextromethorphan (DXM) and its active metabolite dextrorphan (DXO), and similarly to them, acts as a potent agonist of the σ1 receptor (Ki = 151 nM). However, unlike DXM and DXO, it does not act significantly as an NMDA receptor antagonist (Ki = 16,978 nM), and for this reason, lacks dissociative effects, thereby having reduced side effects and abuse potential in comparison.

|
Levomethorphan (INN, BAN) is an opioid analgesic of the morphinan family that has never been marketed. It is the L-stereoisomer of racemethorphan (methorphan). The effects of the two isomers of the racemethorphan are quite different, with dextromethorphan (DXM) being an antitussive at low doses and a dissociative hallucinogen at much higher doses. Levomethorphan is about five times stronger than morphine.

Following RHD's 2009 bankruptcy, it renamed itself Dex One Corporation retaining its headquarters in Cary, North Carolina. In August 2012, Dex One and SuperMedia LLC announced their two companies would be merging to form Dex Media, Inc. The merger was completed on April 30, 2013 and the company began trading publicly on the NASDAQ stock exchange on May 1, 2013 under the symbol DXM.

The development of a potentially life-threatening serotonin syndrome (also more recently classified as "serotonin toxicity") may occur with venlafaxine treatment, particularly with concomitant use of serotonergic drugs, including but not limited to SSRIs and SNRIs, many hallucinogens such as tryptamines and phenethylamines (e.g., LSD/LSA, DMT, MDMA, mescaline), dextromethorphan (DXM), tramadol, tapentadol, pethidine (meperidine) and triptans and with drugs that impair metabolism of serotonin (including MAOIs). Serotonin syndrome symptoms may include mental status changes (e.g. agitation, hallucinations, coma), autonomic instability (e.g.

Examples of antagonists, or more appropriately named receptor channel blockers, of the NMDA receptor are APV, amantadine, dextromethorphan (DXM), ketamine, magnesium, tiletamine, phencyclidine (PCP), riluzole, memantine, methoxetamine (MXE), methoxphenidine (MXP) and kynurenic acid. While dizocilpine is generally considered to be the prototypical NMDA receptor blocker and is the most common agent used in research, animal studies have demonstrated some amount of neurotoxicity, which may or may not also occur in humans. These compounds are commonly referred to as NMDA receptor antagonists.

In the autumn of 2003 he was diagnosed with Head and neck cancer. During several months of chemo- and radiation- therapy he wrote a semi-biographical novel titled RUNAWAY JESUS, which recounted his experiments with the drug dextromethorphan hydrobromide (DXM), followed by What's so Wrong with Love and Peace- Adventures in the European Underground 1965-67. Both available as E-books at Amazon, iTunes, etc. He survived the Head and neck cancer, but in 2007 was diagnosed with bladder cancer, which was treated with two bladder resections.

Black market ecstasy pills are frequently found to contain other drugs in place of or in addition to methylenedioxymethylamphetamine (MDMA). Since the slang term "ecstasy" usually refers only to MDMA, any pill which contains other compounds may be considered adulterated. 3,4-Methylenedioxyamphetamine (MDA), methylenedioxyethamphetamine (MDEA), amphetamine, methylamphetamine, benzylpiperazine (BZP), trifluoromethylphenylpiperazine (TFMPP), caffeine, ephedrine, pseudoephedrine, and dextromethorphan (DXM) are all commonly found in pills being sold as ecstasy. Less common drugs in ecstasy include diphenhydramine, acetaminophen, 5-MeO-DiPT, 2C-B, procaine, and phencyclidine (PCP).

The authors of this study suggested that this increase is unlikely to be of clinical concern. Caution should be used when taking cough medicine containing dextromethorphan (DXM) as serotonin syndrome has been reported. Bupropion has been found to significantly increase citalopram plasma concentration and systemic exposure; the interaction with escitalopram had not been studied, but some monographs warned of the potential interaction. Escitalopram can also prolong the QT interval and hence it is not recommended in patients that are concurrently on other medications that also have the ability to prolong the QT interval.

The remaining symptoms are explained after the discovery of his use of DXM (mixed with alcohol to prevent brain damage), which he used to reduce his intellect. As Sidas regains his status of intellectual genius by not abusing the addictive medicine, he begins work in applied physics, drawing a schematic for a toroidal helicon plasma device, and is reassured that he cannot relate to his wife with his original intellect. House, relating to his situation, essentially helps "lobotomize Einstein" by giving him back his meds, as the patient wishes to be dumb and happy rather than smart and miserable. House tries to break up Lucas and Cuddy at Thanksgiving dinner.

The activity of the NMDA receptor is affected by many psychoactive drugs such as phencyclidine (PCP), alcohol (ethanol) and dextromethorphan (DXM). The anaesthetic and analgesic effects of the drugs ketamine and nitrous oxide are partially due to their effects on NMDA receptor activity. Since 1989 memantine has been recognized to be an uncompetitive antagonist of the N-methyl-D-aspartate receptor (NMDA receptor), entering the channel of the receptor after it has been activated and thereby blocking the flow of ions. The NMDA receptor channels play an important role in synaptic plasticity and synapse formation underlying memory, learning and formation of neural networks during development in the central nervous system (CNS).

Levomethorphan is a prodrug to levorphanol, analogously to DXM acting as a prodrug to dextrorphan or codeine behaving as a prodrug to morphine. As such, levomethorphan has similar effects to levorphanol but is less potent as it must be demethylated to the active form by liver enzymes before being able to produce its effects. As a prodrug of levorphanol, levomethorphan functions as a potent agonist of all three of the opioid receptors, μ, κ (κ1 and κ3 but notably not κ2), and δ, as an NMDA receptor antagonist, and as a serotonin-norepinephrine reuptake inhibitor. Via activation of the KOR, levomethorphan can produce dysphoria and psychotomimetic effects such as dissociation and hallucinations.

No legal distinction currently exists in the United States between medical and recreational use, sale, or purchase. Some states and store chains have implemented restrictions, such as requiring signatures for DXM sale, limiting quantities allowable for purchase, and requiring that purchasers be over the age of majority in their state. The sale of dextromethorphan in its pure powder form may incur penalties, although no explicit law exists prohibiting its sale or possession, other than in Illinois. Cases of individuals being sentenced to time in prison and other penalties for selling pure dextromethorphan in this form have been reported, because of the incidental violation of more general laws for the sale of legitimate drugs – such as resale of a medication without proper warning labels.

William E. White, author of the "DXM FAQ", has compiled informal research from correspondence with dextromethorphan users suggesting that heavy abuse may result in various deficits corresponding to the brain areas affected by Olney's lesions; these include loss of episodic memory, decline in ability to learn, abnormalities in some aspects of visual processing, and deficits of abstract language comprehension. In 2004, however, White retracted the article in which he made these claims. A formal survey of dextromethorphan users showed that more than half of users reported experience of these withdrawal symptoms individually for the first week after long-term/addictive dextromethorphan use: fatigue, apathy, flashbacks, and constipation. Over a quarter reported insomnia, nightmares, anhedonia, impaired memory, attention deficit, and decreased libido.

NMDA receptors have a very important role in modulating long-term excitation and memory formation. NMDA antagonists such as dextromethorphan (DXM, a cough suppressant), ketamine (a dissociative anaesthetic), tiletamine (a veterinary anaesthetic) and ibogaine (from the African tree Tabernanthe iboga) are being studied for their role in decreasing the development of tolerance to opioids and as possible for eliminating addiction/tolerance/withdrawal, possibly by disrupting memory circuitry. Acting as an NMDA antagonist may be one mechanism by which methadone decreases craving for opioids and tolerance, and has been proposed as a possible mechanism for its distinguished efficacy regarding the treatment of neuropathic pain. The dextrorotary form (dextromethadone), which acts as an NMDA receptor antagonist and is devoid of opioid activity, has been shown to produce analgesia in experimental models of chronic pain.
