Ketamin Sine Panpharma (Ketamine)

Ketamine acts as an NMDA receptor antagonist and is employed in anesthesia and pain management.

• Induction of anesthesia: provides rapid onset of dissociative anesthesia for surgical procedures.
• Procedural sedation: enables safe sedation for diagnostic or minor therapeutic procedures.
• Acute pain analgesia: delivers potent analgesia for severe pain in emergency or postoperative settings.
• Severe traumatic injury analgesia: offers rapid pain relief and sedation for patients with major trauma.
• Bronchoscopy sedation: facilitates patient comfort and airway control during bronchoscopic examinations.
• Pediatric anesthesia: provides age‑appropriate dissociative anesthesia for children undergoing surgery.

• Ketamine binds to the phencyclidine site within the NMDA receptor complex, acting as a non‑competitive antagonist. This blockade reduces excitatory glutamate transmission, leading to dissociative anesthesia, analgesia, and sympathetic stimulation. The drug also interacts with opioid receptors and monoaminergic pathways, contributing to its analgesic and psychomimetic effects.

Ketamine may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects

• Nausea and vomiting: mild to moderate gastrointestinal upset.
• Dizziness or vertigo: transient sense of imbalance.
• Hypertension or tachycardia: elevation of blood pressure and heart rate.
• Visual disturbances: blurred or double vision.
• Salivation increase: excess oral secretions.

Serious or Rare Side Effects

• Respiratory depression: reduced breathing effort requiring support.
• Emergence delirium: vivid hallucinations or agitation during recovery.
• Seizures: rare convulsive episodes.
• Severe hypertension: potentially dangerous blood pressure spikes.
• Cardiac arrhythmias: irregular heart rhythms that may need intervention.

Ketamine requires careful clinical monitoring and patient assessment before and during use.

• Dose individualization: adjust based on patient age, weight, and clinical response.
• Cardiovascular monitoring: observe blood pressure and heart rate throughout administration.
• Respiratory monitoring: watch for hypoventilation or apnea, especially with concurrent depressants.
• Psychiatric effects: be aware of emergence reactions, dysphoria, or hallucinations.
• Contraindications: avoid in patients with known hypersensitivity to ketamine.
• Store below 25°C: keep in original container, protect from light and moisture.

Ketamine can interact with several drug classes, altering its safety profile.

Major Interactions (Avoid)

• Central nervous system depressants (e.g., opioids, benzodiazepines): additive respiratory depression risk.
• Sympathomimetic agents (e.g., epinephrine): may exacerbate hypertension and tachycardia.
• Monoamine oxidase inhibitors: potential for hypertensive crisis.

Moderate Interactions (Monitor Closely)

• Alcohol: can increase sedation and respiratory effects.
• Anticholinergics: may affect secretions and airway management.
• Inhaled anesthetics: may potentiate cardiovascular effects when used together.
