Ketamine has emerged as a versatile therapeutic agent with applications spanning anesthesia, pain management, and psychiatric disorders. This review examines ketamine's clinical utility across diverse administration routes, including intravenous, intramuscular, intranasal, and oral, emphasizing the need to individualize dosing regimens. We explore factors influencing ketamine dosing, such as patient characteristics (age, weight, comorbidities), concomitant medications, and desired clinical effects, while balancing efficacy and side effects. The impact of dose, infusion rate, and administration frequency on therapeutic outcomes is analyzed to provide a comprehensive understanding of its clinical implications. The review highlights the critical role of individualized dosing regimens tailored to patient-specific factors. The therapeutic effects of ketamine are dose-dependent, with infusion rate and administration frequency significantly influencing both efficacy and safety. Achieving a balance between clinical benefits and potential side effects remains paramount. There are gaps in knowledge, necessitating for further research into long-term effects, alternative administration routes, and personalized approaches informed by pharmacokinetic variability. Developing standardized, evidence-based protocols and exploring alternative strategies will improve ketamine's therapeutic potential while addressing safety, misuse, and availability concerns.

Background And Aim: Echocardiographic assessment in equines is typically performed on standing animals; however, no studies have evaluated left ventricular function in anesthetized mules using high-dose xylazine. Given the unique pharmacokinetics in mules and their higher anesthetic requirements, this study aimed to assess the effects of acepromazine-xylazine-diazepam-ketamine anesthesia, using the upper limit xylazine dose (1.6 mg/kg), on the left ventricular size and function in mules.

This review examines ketamine's neurotoxic potential across preclinical and clinical studies. The authors synthesized data from preclinical models, then integrated findings from human clinical trials of esketamine and observational studies in recreational users. Animal studies have found that repeated or high-dose subanesthetic ketamine administration results in consistent excitotoxic neuronal damage and lasting cognitive deficits, especially in perinatal animals.

Introduction: Anxiety has been described in the initial stages of schizophrenia, and affective flattening in the chronic illness. The etiology remains unknown. Ketamine, a noncompetitive N-Methyl-D-amino-aspartate acid (NMDA) receptor antagonist, is used in rats as a translational model of schizophrenia.

Background: As a non-competitive blocker of the -methyl-d-aspartate receptor, ketamine is widely used for anesthesia and pain relief in clinical settings. However, certain neurological side effects may appear if it is used for the long term. According to clinical observations, anesthetic doses of ketamine trigger postoperative neurocognitive dysfunction in elderly patients, while subanesthetic doses of ketamine suppress the postoperative neuronal pyroptosis in the hippocampus, ameliorating the cognitive function.

The presence of drugs of abuse in freshwater systems is an emerging environmental concern with potential ecological implications. This systematic literature review examines the global occurrence and distribution of ten highly consumed drugs in rivers, including stimulants (cocaine, amphetamine, methamphetamine, 3,4-methylenedioxy-methamphetamine or MDMA, ketamine) and opioids (codeine, fentanyl, methadone, morphine, tramadol). Using a multi-stage screening process, we identified peer-reviewed articles published between 2012 and 2022, yielding a final dataset covering 225 unique rivers and 865 distinct sampling points across diverse geographic regions.
