What is ketamine?

Ketamine is a drug that is commonly used both for humans and in anesthesia animals, pain relief, also known as analgesia and the treatment of respiratory diseases that disrupt breathing. It is also studied for use in psychiatric treatment. Some people take it recreational for their effects changing the mind, although its sale for this purpose is widely prohibited. Ketamine chemical formula is C _{13 h 16 clno. It can enter the body intravenously, as is usually done for medical use, or is smoked, inhaled or polel.}

Ketamine is an antagonist of the NMDA receptor, which means that it affects the nervous system by interfereing the normal functioning of molecules called N-methyl D-aspartate (NMDAR) receptors. NMDAR molecules in cells are receptors for excitation neurotransmitter glutamate, which is important for the transmission of nerve impulses, and thus to a person's ability to perceive sensory data such as pain signals. In large quantities, also forbroid opioid receptors, causing DALast analgesic effects. Some research also shows that the drug promotes sleep similar to the inhibition of the cyclic nucleotide channel 1 called HCN1, the protein involved in the electrical control in the nervous system.

The most common use of ketamine is as an intravenous general anesthetic during medical procedures. Due to its potential hallucinogenic effects, it is often used as a supplement to inhalation anesthetics rather than itself. Unlike most anesthetics, it usually causes the patient's heart rate and blood pressure to rise rather than fall. As a result, it is useful for the treatment of patients who have been able to lose a large amount of fluid such as trauma victims. It can also be administered in the form of fluid or cream as a local anesthetic.

It is also used as intravenous analgesic for pain relief. Like its use as an anesthetic, ketamine is usually not usedHe himself because of his hallucinogenic effects. Instead, a small amount is combined with opioids. Analgesics and local anesthetics containing ketamine are particularly effective for cancer pain and damage to the nervous system. In addition to use in humans, the drug is often used by veterinarians as analgesic or antenetic for animals.

Ketamine has other medically useful effects. It is used to treat bronchospasms, muscle structure in the respiratory system that disrupts breathing. Bronchospasms are common among suffering conditions such as asthma, anaphylaxis and chronic bronchitis, and are potentially fatal in serious cases. It is also effective treatment of depression in some patients and can cause significant improvements in patients with depression who are resistant to other antidepressants. It is also investigated as possible treatment of gnawing symptoms in opiate regeneration.

Ketamine is also used as a recreational drug, although it is widely forbidden and potentially dangerous. For this purpose Je usually smoked or inhaled in the form of powder. It can cause intense hallucinations and a change in consciousness called a dissociative state in which the perception of the user of both the outside world and its own body and identity seems distant, dreamy or unreal. Given the importance of glutamate in learning and memory creation, the user's memory is experienced as soon as it ends, often fragmentary or completely missing. Strong use may affect brain physiology and cause memory deterioration, and some research suggests that lower use levels may disrupt the development of dendrites in nerve cells if it continues for a longer period of time.
