Ketamine

Introduction

Ketamine is a fast-acting anesthetic medicine that belongs to the class of dissociative anesthetics. It is commonly used in medical settings for induction and maintenance of anesthesia. Ketamine is also used for pain management, sedation, and sometimes in the treatment of depression and other psychiatric disorders under controlled supervision. It works quickly, has reliable effects, and is often chosen for patients with emergency or critical care needs.

Uses of Ketamine

• Induces anesthesia during surgeries
• Provides pain relief in emergency and post-surgical settings
• Treats severe depression and suicidal thoughts (low-dose therapy)
• Used in sedation for intensive care patients
• Manages chronic pain conditions

How Ketamine Works

Ketamine blocks NMDA receptors in the brain, disrupting pain signals and creating a dissociative state. This mechanism makes it effective for anesthesia, pain relief, and depression treatment.

• Effective for treatment-resistant depression
• Can be used for sedation in critically ill patients
