Ztlido lidocaine topical system 1.8?

See the DrugPatentWatch profile for Ztlido

Ztlido® Lidocaine Topical System 1.8 % (also sold as LidoPatch® or similar)
A 1.8 % lidocaine‑containing topical anesthetic patch used for localized neuropathic pain.

1. What it is

  • Active ingredient: Lidocaine 1.8 % (w/w)
  • Form: Adhesive patch (often 12 hr wear time) that delivers lidocaine directly to the skin and underlying tissues.
  • Indications (FDA‑approved):
    • Post‑herpetic neuralgia (PHN)
    • Peripheral neuropathic pain (e.g., diabetic neuropathy, trigeminal neuralgia)
    • Pain from musculoskeletal injuries (in some jurisdictions)

2. How to Use (Typical Instructions)

Step What to Do Tips
1 Clean the skin where the patch will be applied (soap + water, dry). Avoid applying to broken, irritated, or inflamed skin.
2 Remove the protective liner, place patch on the clean area, press firmly for 10‑15 s. Do not wrap the patch with additional adhesive tapes.
3 Wear the patch for up to 12 hr (or as directed by your clinician). If the patch becomes loose, replace with a fresh one.
4 Remove the patch by gently peeling from the side. Wash hands after removal.
5 Maximum: No more than 2 patches per day on a single area, and no more than 15 % of body surface area overall. Do not use patches on a larger area than recommended.

Do NOT apply the patch over a large area (>15 % body surface) or on broken skin unless a physician specifically advises it.

3. Common Side Effects

Category Typical Symptoms When to Call a Physician
Local (skin) Redness, itching, burning, mild swelling If the reaction is severe, spreads, or doesn’t resolve in 24 hr
Systemic Dizziness, headache, tinnitus, light‑headedness, fainting If any of these occur, stop use and seek medical help
Rare Allergic contact dermatitis (rash, hives), anaphylaxis Seek emergency care for difficulty breathing, swelling of face/neck, severe rash

4. Contraindications & Precautions

Category Key Points
Contraindicated Known hypersensitivity to lidocaine or any local anesthetic.
Use With Caution • Heart disease (especially conduction abnormalities, heart block) – lidocaine can affect cardiac conduction.
• Hepatic impairment – lidocaine is metabolized by the liver; higher systemic levels can accumulate.
• Pregnancy & Breastfeeding – limited data; use only if benefits outweigh risks.
• Elderly – increased sensitivity; monitor for systemic effects.
Avoid • Applying patches to large areas or broken skin.
• Re‑applying after removal unless advised.
Drug Interactions • CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir) may increase systemic lidocaine levels.
• QT‑prolonging agents (sotalol, amiodarone, quinidine) – avoid concomitant use.
• Other local anesthetics (e.g., prilocaine creams) – avoid simultaneous use to reduce overdose risk.

5. Storage & Handling

  • Keep at room temperature (15–30 °C / 59–86 °F).
  • Avoid moisture (do not store in the bathroom).
  • Keep out of reach of children and pets.
  • Do not use after the expiry date shown on the package.
