Ketamine Hydrochloride solution

What is Ketamine

Ketamine Hydrochloride solution. Ketamine is a dissociative anesthetic used medically for induction and maintenance of anesthesia. Ketamine hydrochloride is also used for the treatment of depression and pain management in humans and animals. It is a novel compound that was derived from phencyclidine in 1962 in pursuit of a safer anesthetic with fewer hallucinogenic effects.

At anesthetic doses, ketamine induces a state of dissociative anesthesia, a trance-like state providing pain relief, sedation, amnesia. Ketamine’s distinguishing features as anesthesia are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. At lower, sub-anesthetic doses, it is a promising agent for pain and treatment-resistant depression. As with many antidepressants, the results of a single administration decreases with time. The long-term effects of repeated use of ketamine hydrochloride solution are largely unknown, and are an area of active investigation.

Urinary and Liver toxicity have been reported among regular users of high doses of ketamine for recreational purposes. Ketamine is an NMDA receptor antagonist, accounting for most of its psychoactive effects on users.

Ketamine hydrochloride was first synthesized in 1962 and it was approved for it to be used in the United States of America in 1970. The drug is regularly used in veterinary medicine and was extensively used for surgical anesthesia in the Vietnam War. Along with other psychotropic drugs, it is on the World Health Organization’s List of Essential Medicines. It is available as a generic medication. When used as a recreational drug, it is found both in crystalline powder and liquid form, and is often referred to by recreational users as “Special K” or simply “K”. It is used as a recreational drug for its hallucinogenic and dissociative effects it has in humans.

Ketamine Dosage

Ketamine is supposed to be administered under the supervision of a doctor/physician. The initial dose of ketamine administered intravenously (IV) ranges from 1 mg/kg to 4.5 mg/kg. The average amount required to produce 5 to 10 minutes of surgical anesthesia is 2 mg/kg. The initial dose of ketamine administered intramuscularly (IM) ranges from 6.5 to 13 mg/kg. A dose of 10 mg/kg usually produces 12 to 25 minutes of surgical anesthesia. Ketamine hydrochloride may interact with barbiturates or narcotics. Tell your doctor all medications you use.

Uses of Ketamine Hydrochloride

Used as Anesthesia: The effect of ketamine on the respiratory and circulatory systems is different from that of other anesthetics. It suppresses breathing much lesser than most anesthetics being used. Ketamine is an option in children as the sole anesthetic for minor procedures or as an induction agent followed by neuromuscular blocker and tracheal intubation, In particular, children with cyanotic heart disease and neuromuscular disorders are good candidates for ketamine anesthesia .

When used at anesthetic doses, ketamine usually stimulates rather than depresses the circulatory system. Protective airway reflexes are preserved and it is sometimes possible to administer ketamine anesthesia without protective measures to the airways. Psychotomimetic effects limit the acceptance of ketamine however, lamotrigine and nimodipine decrease psychotomimetic effects and can be counteracted also by benzodiazepines or Propofol administration. Ketofol is a combination of ketamine and propofol medications.

Ketamine hydrochloride is frequently used as anesthesia in severely injured people and appears to be safe.

It has been widely used for emergency surgery in field conditions in war zones, for instance during the Vietnam War. A 2011 clinical practice guideline supports the use of ketamine as a sedative in emergency medicine, including during physically painful procedures. It is the drug of choice for people in traumatic shock who are at risk of hypotension. Ketamine is unlikely to lower blood pressure, which is dangerous for people with severe head injury, in fact it can raise blood pressure, often making it useful in treating such injuries.

Pain: Ketamine is used for acute pain treatment in emergency departments and in the perioperative period for individuals with refractory pain. These have lower doses than those used for anesthesia. They are usually referred to as sub-anesthetic doses. Adjunctive to morphine or on its own, ketamine reduces morphine use, pain level, nausea, and vomiting after surgery. Ketamine is likely to be most beneficial for surgical patients when severe post-operative pain is expected, and for opioid-tolerant patients.

Depression: Ketamine acts as an antidepressant, although its effect is transient. Intravenous ketamine infusion in treatment-resistant depression may result in improved mood within 4 hours reaching the peak at 24 hours. A single dose of intravenous ketamine has been shown to result in a response rate greater than 60% as early as 4.5 hours after the dose (with a sustained effect after 24 hours) and greater than 40% after 7 days. Even though there are only a few pilot studies studying the optimal dose, increasing evidence suggests that 0.5 mg/kg dose injected over 40 minutes gives an optimal outcome. The antidepressant effect of ketamine is diminished at 7 days, and most people relapse within 10 days, although for a significant minority the improvement may last 30 days or more. The greatest challenge with ketamine treatment can be the length of time that the antidepressant effects lasts after finishing a course of treatment. A possible option may be maintenance therapy with ketamine which usually runs twice a week to once in two weeks. Ketamine may decrease suicidal thoughts for up to three days after the injection.

A Cochrane review of randomized controlled trials in adults with unipolar major depressive disorder, found that when compared with placebo, people treated with either ketamine or esketamine experienced reduction or remission of symptoms lasting 1 to 7 days. There were 18.7% (4.1 to 40.4%) more people reporting some benefit and 9.6% (0.2 to 39.4%) more who achieved remission within 24 hours of ketamine treatment. Among people receiving esketamine, 2.1% (2.5 to 24.4%) more encountered some relief at 24 hours and 10.3% (4.5 to 18.2%) more had few or no symptoms. These effects did not persist beyond one week, although higher dropout rate in some studies mean that the duration of benefit remains unclear.

Ketamine may partially improve depressive symptoms among people with bipolar depression, at 24 hours after treatment, but not 3 or more days. Potentially, 10 more people with bipolar depression per 1000 may experience brief improvement, but not cessation of symptoms, one day following treatment. These estimates are based on limited available research.

Near-death experience: Most people who were able to remember their dreams during ketamine anesthesia report near-death experiences when the widest possible definition of an near death experience is used. Ketamine can reproduce features that commonly have been associated with near-death experiences. A 2019 large-scale study found that written reports of ketamine experiences had a high degree of similarity to written reports of near-death experiences in comparison to other written reports of drug experiences.

Seizures:Ketamine hydrochloride is used to treat status epilepticus that is not responsive to standard treatments.

Asthma: It is used as possible therapy for children with severe acute asthma who do not respond to standard treatment. This is due to its bronchodilator effects. A 2012 Cochrane review found there were minimal adverse effects reported, but the limited studies showed no significant benefit.
