Lidocaine topical patch

Lidocaine topical patches deliver targeted, localized pain relief by numbing peripheral nerves at the site of application. They are widely used for neuropathic and musculoskeletal pain, particularly when systemic analgesics are undesirable.

The most common formulation is Lidocaine 5% patch, designed for controlled, sustained transdermal delivery over several hours, providing effective pain reduction with minimal systemic absorption.

Key Benefits

• Localized pain control without systemic opioid exposure

• Non-greasy, easy-to-apply transdermal system

• Suitable for chronic and post-injury pain management

• Favorable safety profile when used as directed

Common Indications

• Postherpetic neuralgia (PHN)

• Localized neuropathic pain

• Back pain and muscle strain

• Arthritis-related focal pain

• Post-surgical localized pain

Mechanism of Action

Lidocaine blocks voltage-gated sodium channels in neuronal membranes, preventing initiation and conduction of nerve impulses. This results in temporary loss of pain sensation at the application site without affecting consciousness or motor function.

Administration

• Route: Topical (transdermal patch)

• Typical Use: Apply to intact skin for up to 12 hours within a 24-hour period

• Patches may be cut to fit the affected area (depending on manufacturer guidance)
