Cardene in 0.83% sodium chloride in plastic container?

Cardene (L‑carnitine) – 10 % IV Solution in 0.83 % Sodium Chloride (Plastic Vial)

Item	Details
Active Ingredient	L‑carnitine (100 mg mL⁻¹ – 10 % solution)
Vehicle	0.83 % Sodium Chloride (≈ 83 g L⁻¹) + water for injection
Container	10 mL polypropylene plastic vial, capped with a screw‑top lid
Appearance	Clear, colourless to slightly pale yellow liquid
Labeling	Manufacturer, batch number, expiry date, sterility statement, “Use at room temperature”
Typical Strength	1 g of L‑carnitine per 10 mL vial (100 mg mL⁻¹)
Isotonicity	0.83 % NaCl ≈ 83 g L⁻¹ (≈ 0.83 % w/v); slightly hypotonic compared with 0.9 % saline, but still considered “normotonic” for most IV uses

Why the 0.83 % NaCl?

• Isotonicity: 0.83 % NaCl provides a near‑physiological osmolarity (≈ 290 mOsm kg⁻¹) which reduces the risk of hemolysis or phlebitis when the solution is administered IV.
• Compatibility with L‑carnitine: L‑carnitine is soluble in a mildly hypotonic saline; 0.83 % is the formulation chosen by the manufacturer to maintain stability and avoid precipitation.

Indications & Typical Use

Condition	Typical Dose (Adults)	Administration
Inherited or acquired carnitine deficiency (e.g., primary carnitine deficiency, mitochondrial disorders)	0.5–1.0 g kg⁻¹ day⁻¹ (often divided)	IV infusion 30–60 min; may be repeated daily or as needed
Severe metabolic acidosis or hypoglycemia in neonatal or pediatric patients	10–20 mg kg⁻¹ (single dose)	Rapid IV push or infusion
Support in critical care (e.g., sepsis, cardiac failure)	30–50 mg kg⁻¹ (single or repeated)	Short‑term infusion

Note: Exact dosing is individualized and should be guided by serum carnitine levels, clinical response, and the treating physician’s protocol.

Storage & Shelf Life

Condition	Storage	Shelf Life
Room Temperature (15–25 °C)	Keep vial upright; avoid prolonged exposure to high heat ( >30 °C )	3 years from manufacture if unopened; 7 days after opening if sealed properly
Refrigeration (≤ 8 °C)	Only for certain formulations that require cold storage; not typical for Cardene 10 %	Use within 48 h after refrigeration if re‑opened
Avoid light	Store in the original opaque plastic container or in a dark place	Same as above

• Do not freeze – freezing can cause precipitation of the drug and compromise sterility.
• Do not mix with other IV solutions unless the manufacturer or a compounding pharmacist confirms compatibility.

Handling & Administration Tips

1. Check the vial: Inspect for particulate matter, cloudiness, or discoloration before use.
2. Use a sterile needle/IV catheter.
3. Dilute if needed: If the dose is large, the vial can be diluted with 0.9 % NaCl or 5 % dextrose to reach the desired volume; do so under aseptic conditions.
4. Infuse slowly: Typical infusion rates range from 10 – 15 mL min⁻¹. Faster rates may increase the risk of irritation.
5. Monitor: Watch for infusion reactions, especially in patients with a history of hypersensitivity to carnitine or sodium chloride.

Adverse Reactions

Symptom	Frequency	Notes
Gastro‑intestinal (nausea, vomiting, abdominal cramps)	Rare	Usually dose‑related; reduce dose if persistent
Allergic reactions (rash, urticaria, anaphylaxis)	Very rare	Use only if no other causes; pre‑medication not routine
Local irritation (phlebitis, extravasation)	Low	Ensure proper IV site and gentle infusion

---

Contraindications & Precautions

• Hypersensitivity to L‑carnitine, sodium chloride, or any excipients.
• Pregnancy & Lactation: Limited data; use only if clearly needed.
• Renal impairment: L‑carnitine is primarily renally cleared; monitor serum levels if available.
• Drug interactions: None specific, but avoid concurrent use of high‑dose calcium‑binding agents that may alter plasma carnitine.

---

Disposal

• Unopened vials: Store at room temperature and discard at expiry.
• Opened vials: Follow institutional sharps and hazardous waste protocols; do not reuse the vial or needle.
• Residual solution: If any remains, it should be disposed of with other hazardous drug waste, not poured down the drain.

Quick Reference Checklist (for Clinicians)

• [ ] Verify dosage and patient weight.
• [ ] Inspect vial for integrity.
• [ ] Dilute appropriately if large volume.
• [ ] Infuse at recommended rate; monitor for reactions.
• [ ] Document serum carnitine levels (if available) and clinical response.
• [ ] Store remaining dose at recommended temperature; discard after 7 days.

Bottom line:
Cardene 10 % is a sterile, isotonic IV solution of L‑carnitine in a 0.83 % NaCl vehicle, packaged in a polypropylene vial that should be stored at room temperature, protected from light, and used within 7 days after opening. It’s employed primarily to correct carnitine deficiency and in certain acute metabolic emergencies, with a good safety profile when used per the indicated protocol.
