Ketamine – Definition, Uses, & Facts

Ketamine, also called 2-(2-ketamine)-2-(methylamino)-cyclohexanone or CI581, general anesthetic agent related structurally to the hallucinogen phencyclidine (PCP). Ketamine was first synthesized at Parke Davis Laboratories by American scientist Calvin Stevens, who was searching for a different anesthetic to replace PCP, which was not suitable for human use because of the severe hallucinogenic effects it produced upon the recovery of consciousness. Ketamine was initially developed by Belgium in 1963. It was approved for use in people by U.S. Food and Drug Administration in 1970. In the following years, it was used for treating American soldiers in the Vietnam War. Today, since ketamine produces minor hallucinogenic-related side effects in humans, it is utilized in veterinary anesthetic. However, the drug can have a number of applications for human medicine, especially as an anesthetic for infants as well as for those who undergo minor surgery. It is also used to treat depression or chronic pain.

Unlike inhalation anesthetics or the sedative agents (e.g., narcotics and benzodiazepines), ketamine does not affect respiration, or other vital actions of our central nervous system. So, ketamine has a wide range of safety. Furthermore, it’s distinct from other anesthetics as it has three major effects that include analgesia (pain relief) and analgesia (pain relief), hypnosis (sedation) and amnesia. The drug is known particularly for its capacity to create an euphoric (cataleptic) state that is characterised by a deficiency of pain sensation, insanity and a heightened the muscle tone. These features are typically associated with open eyes, jumping eye movements (nystagmus) as well as involuntary movements of the limbs.

Ketamine works by altering the activity of neurons in the brain. This is done through the drug’s inhibition of neuronal uptake of various neurotransmitters, including serotonin, glutamate, as well as dopamine. The result is a depression of neural communication between the thalamus and the cerebral cortex, leading to an uncoupling of brain activity that is associated with memory, sensory experience, motor functions and emotions. Ketamine stimulates the activity of the limbic brain, a region of the brain that plays a role in controlling specific autonomic functions and in integrating different brain functions as well as those related to motivation and emotion.

In clinical use ketamine is administered via intramuscular injection or intravenously. A few minor side effects from the medication include tearing (lacrimation) as it emerges from the state of dissociative anesthetic. Patients might experience severe and troubling hallucinogenic effects, such as intense dreams and delusions upon awakening. these effects are more common for adults than children. Hallucinations are directly related to dose. So, higher doses can cause more severe delirium as well as other symptoms of hallucination than lower doses.

Ketamine’s ability to produce hallucinogenic effects in just a few minutes following it is administered can lead to abuse as recreational drugs. The dissociative effects of ketamin it occurs when high doses of ketamine are taken is often described by recreational users as the “K hole” a separation between the body and mind as well as the hallucinatory “out of body” experience. Ketamine is also known under a variety of street names, such as”K,” special K jet, super acid, as well as cat valium. It can be inhaled, administered by mouth, and the effects last from 30 minutes to over an hour. However, for at least one or two days after using the drug, people may experience signs of schizophrenia, memory loss, impaired judgement, and insufficient coordination. In addition, long-term abuse could cause paranoia and depression, as well as other indicators of cognitive dysfunction. A lot of people appear in a state of stupor after the drug is taken in low doses; however the high doses could cause an unconsciousness, depression of the heart, and death.
