LIGNOCAD

Definition: LIGNOCAD is a local anesthetic formulation, primarily composed of Lidocaine Hydrochloride, used for topical and injectable numbing in medical, dental, and surgical procedures.

INTRODUCTION

LIGNOCAD is designed for rapid and effective pain relief, commonly used in:

• Dental procedures (tooth extractions, fillings).

• Minor surgeries (skin incisions, suturing).

• Diagnostic tests (lumbar punctures, biopsies).

It acts by blocking sodium channels in nerve cells, preventing pain signal transmission.

DESCRIPTION

Active Ingredient:

• Lidocaine HCl (1%–2% for injectable; 2%–5% for topical).

Formulations:

1. Injectable Solution (most common for dental/surgical use).

2. Topical Gel/Spray (for mucous membranes or skin pre-treatment).

3. Patch (slow-release for prolonged analgesia).

Key Properties:

• Onset:

  • Injectable: 1–3 minutes.

  • Topical: 3–5 minutes (mucous membranes); 10–15 minutes (skin).

• Duration:

  • Without epinephrine: 30–60 minutes.

  • With epinephrine: 2+ hours (vasoconstriction prolongs effect).

USES

1. Dental:

   • Local anesthesia for tooth procedures.

   • Gum numbing before injections.

2. Medical/Surgical:

   • Suturing wounds, incision drainage.

   • IV cannulation pain reduction.

3. Dermatology:

   • Laser treatments, mole removal.

4. Emergency Care:

   • Rapid pain control for minor trauma.

SIDE EFFECTS

Common (Mild):

• Temporary numbness beyond the target area.

• Minor swelling or redness at the injection site.

• Metallic taste (if used orally in dental procedures).

Rare (Severe):

• Allergic reactions (rash, anaphylaxis – rare with lidocaine).

• Cardiovascular effects (if accidentally injected into a blood vessel):

  • Low blood pressure, arrhythmias.

• Central Nervous System (CNS) toxicity (high doses):

  • Dizziness, seizures.

IMPORTANCE

• Gold-standard local anesthetic due to its safety and efficacy.

• Fast-acting, making it ideal for quick procedures.

• Versatile (usable for injections, sprays, gels).

STORAGE

• Injectable: Store at 15–25°C; protect from light.

• Topical: Keep at room temperature; avoid freezing.

• Shelf Life: Typically 2–3 years if unopened.

CONCLUSION

LIGNOCAD is a trusted, multi-purpose anesthetic for pain management in clinics and hospitals. While side effects are rare, proper dosing and administration technique are critical to avoid complications.

Contraindications:

• Allergy to lidocaine or other amide anesthetics.

• Severe liver disease (reduces drug metabolism).

• Not for use in infants without medical supervision.
