Expert opinion on pharmacotherapy

Introduction:

Ketamine has shown promise as a novel treatment for psychiatric disorders. This narrative expert review provides an update on recent advances in ketamine research.

Areas Covered:

Herein we narratively summarize: (1) new efficacy data from clinical trials, (2) real-world effectiveness data, (3) growing safety data, (4) alternative routes of administration, (5) optimization of treatment protocols, (6) considerations for enantiomer variants, (7) new potential indications. Lastly, limitations and challenges to the progression of the field will be discussed.

Expert Opinion:

Evidence supporting the use of intravenous ketamine and intranasal esketamine for depression has dramatically increased with a large number of clinical trials and real-world effectiveness studies supporting antidepressant effects. Larger studies have provided reassuring data supporting an adequate safety profile, including safety data with long term treatment. Alternative routes of administration have shown promise for improving scalability; however, efficacy as compared to intravenous ketamine remains unclear. Promising preliminary data support ketamine's efficacy in other conditions such as bipolar disorders, personality disorders, post-traumatic stress and obsessive compulsive disorder. Further research is needed to optimize protocols, such as combining ketamine with other interventions. Functional unblinding, expectancy related bias and treatment costs remain challenges for the field.

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Parenteral Anesthetics: Overview

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Drug Therapy

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Psychosis: Goals of Pharmacotherapy

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
