Sublimaze

Sublimaze is the brand name for fentanyl citrate injection, a potent synthetic opioid analgesic used by healthcare professionals to relieve severe pain and provide analgesia during anesthesia for surgical procedures. Each milliliter contains fentanyl citrate equivalent to 50 micrograms of fentanyl base in a sterile, preservative-free aqueous solution.

Active Ingredient & Strength:

• Fentanyl citrate (equivalent to 50 mcg fentanyl base per mL), a highly potent mu-opioid receptor agonist that significantly diminishes pain perception.

Key Clinical Uses:
Sublimaze is indicated for:

• Short-term pain relief during and after surgery.

• Premedication and induction of anesthesia as an adjunct to other anesthetic agents.

• Supplemental analgesia in general or regional anesthesia protocols.

It is administered only by trained clinicians in settings equipped to manage airway and respiratory effects.

How It Works (Mechanism of Action):
Fentanyl binds to mu-opioid receptors in the central nervous system, altering pain perception and emotional response to pain with a rapid onset of action (often within minutes when given intravenously) and a relatively short duration of effect (about 30–60 minutes).

Dosage & Administration:

• Route: Intravenous (IV) or intramuscular (IM) injection by a qualified healthcare professional.

• Typical dosing: Clinician-individualized based on patient characteristics and surgical context; small bolus doses (e.g., 25–100 mcg) titrated to effect under monitoring.

Safety, Risks & Precautions:

• Schedule II Controlled Substance: Sublimaze (fentanyl) carries a high risk of abuse, dependence, and addiction.

• Respiratory Depression: A significant risk, potentially life-threatening, especially during initiation or dose increases; requires continuous monitoring.

• Use with Other CNS Depressants: Concomitant use with benzodiazepines and other depressants may result in profound sedation or respiratory compromise.

• Contraindications: Unsuitable for patients with severe respiratory disease, acute asthma, or known hypersensitivity to fentanyl.

Storage & Handling:

• Store at room temperature protected from light, and secure in accordance with controlled substance regulations.

Nota Bene:
The Sublimaze brand name has been discontinued in some jurisdictions, but the active compound, fentanyl citrate injection, remains available in generic forms for clinical use.
