Most side effects peaked within an hour of ketamine administration and were gone within two hours. (nih.gov)
To overcome the limitations associated with side effects and intravenous delivery, ongoing research efforts seek to develop a more practical rapid-acting antidepressant that works in the brain similarly to ketamine. (nih.gov)
This changes a neural biochemical pathway which increases levels of certain proteins, which, in turn, may contribute to or cause the rapid effects of ketamine in the brain. (bbrfoundation.org)
The mind-altering effects of Ketamine are about 10 minutes into the infusion. (quintessencehealthandwellness.com)
The more synapses that regrow, the better the antidepressant effects of ketamine for the patient. (quintessencehealthandwellness.com)
Outcomes provide evidence of an expected neural excitatory and proinflammatory state in cases that could predispose to neuronal damage via NMDAR hyperactivation through kynurenine pathway activation and will provide evidence in humans of possible effects of temporarily blocking NMDAR with a subanesthetic dose (0.5 mg/kg) of ketamine.

Homeostatic plasticity has different functions, and Drs. Monteggia and Kavalali have proposed that it is this type of plasticity which is required for rapid antidepressant action like the kind generated by ketamine. (bbrfoundation.org)

Ketofol is a combination of ketamine and propofol. (wikipedia.org)
This decline was mainly substituted by Ketamine and particularly Propofol. (biomedcentral.com)

Scientists are finding increasing evidence for the benefits of mind-altering drugs such as ketamine, MDMA, and psilocybin mushrooms. (netgalley.com)

This presentation shares the development of a protocol, process, and education for a new practice of intravenous subanesthetic ketamine administration outside of the intensive care units to ensure nurse comfort and competence, patient safety, and positive patient outcomes. (amsn.org)
This article presents a qualitative review and summary about what is known about ketamine dosing, rate of administration, route of administration, duration of treatment, and frequency of sessions. (psychiatrist.com)
There is likely to be a complex interaction between ketamine dose, session duration, route of administration, frequency of administration, and related practice. (psychiatrist.com)
Procedures -Each horse was sedated multiple times by administration of xylazine (treatment X), xylazine and butorphanol (treatment XB), xylazine with 1 of 2 dosages of ketamine (treatment XK1 or XK2), or xylazine and butorphanol with 1 of 2 dosages of ketamine (treatment XBK1 or XBK2). (avma.org)
The ketamine guideline differs from previous prescribing guidelines by addressing administration of a non-opioid. (paproviders.org)
The ketamine guideline provides best practices for the subanesthetic administration of Ketamine for a variety of conditions. (paproviders.org)
We did not see any serious, drug-related adverse events or increased ketamine cravings with a single-administration. (nih.gov)
Currently, we are short of high-quality comparative data for various ketamine administration routes (Xiong et al. (ketamineacademy.com)
2020). The hunt for new ketamine indications has intensified in the last few decades, but some practitioners still want to know if they are giving the medication efficaciously when using non-IV routes of administration. (ketamineacademy.com)
