Marcain Spinal Tung

Bupivacaine hydrochloride, the active ingredient in Marcain Spinal Tung, is a local anesthetic presented as a sterile solution for infiltration use. It provides long‑lasting numbness for surgical, regional and spinal anesthesia procedures. GNH USA supplies Marcain Spinal Tung as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Bupivacaine hydrochloride is a long‑acting amide local anesthetic used in regional and spinal anesthesia.

Surgical anesthesia: provides dense sensory block for operative procedures. Regional anesthesia: enables nerve block for limb or trunk surgeries. Spinal anesthesia: produces rapid and profound analgesia for lower‑body operations. Postoperative analgesia: extends pain relief after surgery, reducing the need for systemic opioids.

Adverse reactions may occur following administration of bupivacaine.

Common Side Effects: - Hypotension: reduced blood pressure after spinal block. - Bradycardia: slower heart rate during or after injection. - Nausea: mild to moderate upset stomach. - Dizziness: feeling light‑headed or unsteady. - Metallic taste: transient taste disturbance. - Headache: post‑dural puncture headache.

Serious or Rare Side Effects: - Cardiac arrest: severe cardiotoxicity, especially with high plasma levels. - Seizures: central nervous system excitation due to high concentrations. - Respiratory depression: inadequate breathing requiring support. - Allergic reaction: rash, itching, or anaphylaxis. - Prolonged motor block: extended loss of muscle function. - Methemoglobinemia: rare blood disorder causing reduced oxygen delivery.

When using Marcain Spinal Tung, clinicians should observe several safety measures.

Allergy assessment: verify no known hypersensitivity to amide‑type local anesthetics. Dose calculation: adjust dose based on patient weight, age, and comorbidities. Cardiovascular monitoring: continuously observe heart rate and blood pressure during administration. Neurological assessment: watch for signs of spinal cord irritation or excessive block. Use with caution in hepatic impairment: reduced metabolism may prolong drug effect. Store below 25°C: keep in the original pack, protect from moisture and light.

Bupivacaine may interact with other medicines, requiring careful management.

Major Interactions (Avoid): - Class I antiarrhythmics (e.g., quinidine): increase risk of cardiotoxicity. - Beta‑blockers: may potentiate bradycardia and hypotension. - General anesthetics (e.g., halothane): additive central nervous system depression.

Moderate Interactions (Monitor Closely): - Opioids: enhance respiratory depression when combined. - Sedatives (e.g., benzodiazepines): increase risk of excessive CNS depression. - Lithium: may heighten neurotoxic effects of bupivacaine.
