Ketamine Injection (e.g., 50 mg/mL × 10 mL) 500 mg

What It Is
Ketamine injection is a medical formulation of ketamine hydrochloride — a general anesthetic used primarily for induction and maintenance of anesthesia in surgical procedures. It produces sedation, amnesia, and analgesia (pain relief) by acting on NMDA receptors in the brain. It may also be used off‑label under strict medical supervision for pain management or psychiatric indications such as treatment‑resistant depression.

Uses and Effects
Ketamine injection is administered intravenously (IV) or intramuscularly (IM) by a healthcare professional. It rapidly induces a dissociative state, making it useful in operating rooms and emergency settings. In controlled medical settings, dosing varies by indication and patient weight. For anesthesia induction, doses often range by weight and route.

Risks and Safety
As a potent anesthetic, ketamine must be administered by trained professionals. Side effects include elevated heart rate and blood pressure, dizziness, confusion, and potentially nausea. Misuse outside clinical settings can be dangerous. It is a controlled substance due to potential for abuse and psychological effects.
