Definition:
NEOVEC 10mg Injection is a novel amino-amide local anesthetic containing Ropivacaine Hydrochloride (10mg/mL), designed for prolonged nerve blocks with reduced cardiotoxicity compared to bupivacaine.
INTRODUCTION
NEOVEC is clinically preferred for:
-
Regional anesthesia (epidural, peripheral nerve blocks)
-
Post-operative pain management (up to 8 hours analgesia)
-
Labor analgesia (low-dose epidural infusions)
It offers differential sensory-motor blockade – numbing pain fibers while sparing motor function at lower doses.
DESCRIPTION
Composition:
-
Ropivacaine HCl (10mg/mL) – S(-)-enantiomer of bupivacaine
-
Preservative-free (single-dose vials)
-
pH 4.0–6.0 (adjusted for stability)
Key Properties:
Parameter | Value |
---|---|
Onset | 10–20 minutes |
Duration | 4–8 hours (dose-dependent) |
Protein Binding | 94% (high) |
Cardiac Safety | Lower risk than bupivacaine |
USES
1. Surgical Anesthesia
-
Epidural: 15–30mg for C-sections
-
Peripheral blocks: 5–10mL (0.5–0.75%) for orthopedic surgeries
2. Pain Management
-
Continuous epidural infusion: 2mg/mL at 6–14mL/hr
-
TAP blocks:Â 20mL (0.2%) for abdominal surgeries
3. Pediatric Use
-
Caudal blocks: 1–2mg/kg (0.2% solution)
SIDE EFFECTS
Common (Dose-related):
-
Hypotension (neuraxial blocks)
-
Nausea (20% with epidurals)
-
Transient neurologic symptoms (1–2%)
Serious (Rare):
-
Cardiotoxicity (only at doses >250mg)
-
Seizures (plasma levels >4.5μg/mL)
-
Allergic reactions (cross-reactivity with other amides)
ADVANTAGES OVER BUPIVACAINE
Feature | NEOVEC (Ropivacaine) | Bupivacaine |
---|---|---|
Motor Block | Less intense | Profound |
Cardiac Safety | Wider therapeutic window | Narrow margin |
Vasoconstriction | Mild (reduced epi-need) | Significant |
DOSAGE GUIDELINES
Application | Concentration | Volume (Max) | Onset | Duration |
---|---|---|---|---|
Epidural | 0.5–1% | 15–30mL | 15min | 3–6hrs |
Nerve Block | 0.2–0.75% | 20–40mL | 10min | 6–8hrs |
Infusion | 0.1–0.2% | 6–14mL/hr | – | Prolonged |
Maximum Dose: 3mg/kg (up to 250mg)
STORAGE & HANDLING
-
Store at 20–25°C (excursions permitted 15–30°C)
-
Protect from light/freezing
-
Single-use only – Discard unused portions
CONTRAINDICATIONS
-
Hypersensitivity to amide local anesthetics
-
Severe hepatic impairment (reduced metabolism)
-
IV regional anesthesia (Bier block) – Risk of systemic toxicity
CONCLUSION
NEOVEC 10mg Injection combines:
✔ Longer action than lidocaine
✔ Safer profile vs bupivacaine
✔ Flexible dosing for surgical/pain applications
Critical Reminders:
-
Use test doses for epidural catheter placement
-
Monitor for CNS toxicity signs (tinnitus, metallic taste)
-
Lipid emulsion (Intralipid)Â must be available for toxicity management
